Year End Review 2022

Looking back at our achievements from 2022
By Corina Pip (@imalittletester) |

It was an amazing year here at the Selenium project, and we wanted to remind you of some of the great things we accomplished.

In terms of releases, we continued to build on top of Selenium 4 which was launched in October 2021. This year we published v4.2, v4.3, v4.4, v4.5, v4.6, and v4.7. These releases included improvements, bug fixes, removal of deprecated functionality, improved error handling, updates of the underlying libraries, support for the latest Chrome DevTools versions to keep you in sync with new browser releases, but also new features.

We introduced the first (beta) version of the embedded Selenium Manager. The purpose of this feature is to help you manage your driver binaries without having to manually update them yourself each time a new version is released. We also introduced observability in the Docker-Selenium images. Another major new feature is native support for scrolling in the Actions API. But these are only some of the highlights of what we released. To get the details for each language we support, you can check out their corresponding Changelog pages: Java, Python, Ruby, Javascript, DotNet.

In terms of events and gatherings, in July our Selenium India Conference took place, this time online. It kicked off with an 8 talk pre-conference event, namely Selenium Lite. We then had a full day of workshops, followed by 2 days of conference. We had over 50 speakers and over 800 participants from around the world. The talks focused on Selenium, the Selenium ecosystem, automation, methodologies and best practices. In case you missed some of these talks, you can still watch them here.

We also held 2 test automation summits: one in San Francisco and one in Berlin. During these workshops the participants, together with some of the maintainers of frameworks from the Selenium ecosystem, built their Selenium based projects, added tests, new features and fixed bugs. During the first summit the participants focused on the BiDi protocol, while during the second one the focus was on Appium and mobile automation.

We are kicking off next year with a few surprises. The Selenium Conference in Chicago just announced the Speaker Lineup. Stay tuned for further details!

Many thanks to everyone who has contributed to the Selenium project for all their hard work this year!

And special thanks to all of you who are using, following and supporting the Selenium project.

From everyone here at SeleniumHQ, may you have the best holidays and an amazing new year. See you in 2023!

SeleniumConf Chicago 2023 Speakers Announced

The SeleniumConf Chicago 2023 Program Review Committee and conference organizers are finalizing the agenda, but in advance of this here is what you can look forward to.
By Bill McGee |

As many of you know, the Selenium Conference returns to an in-person event next March 28-30, 2023 in Chicago, IL. The Program Chairs & Committee, as well as the Extended Program Review Committee, have been hard at work putting together an outstanding lineup of speakers and workshops, and we’re close to releasing the full agenda and a completely re-branded conference website - stay tuned! In the meantime, we wanted you to be among the first to know who will be presenting, announce a new, additional pre-conference workshop, and provide you with some important updates. Here we go!

Keynote Sessions

There will be four plenary keynote presentations across the 2-day conference. Selenium Core Committer Diego Molina will open the conference on Wednesday with the “Selenium: State of the Union” presentation, followed by Quality & Leadership Coach Erika Chestnut presenting “Bigger Than The Box”, where she shares how she has crossed the aisles to elevate and expand the role quality in the organizations that she has worked for. Day 2 kicks off with Mark Winteringham, Ministry of Testing OpsBoss, presenting “What Exactly Do You Do In Test Automation”. The final keynote session will be a Q&A with the Selenium Committers panel.

Confirmed Track Session Presenters

Following the opening keynote presentations, there will be two separate track sessions running in parallel. Here are the confirmed speakers to date and the presentations they will be giving:

New Workshop Added - State Model-Based Testing Using Selenium

We’re pleased to announce a new addition to the optional pre-conference workshop day, State Model-Based Testing Using Selenium, led by Ru Cindrea, Managing Partner and Senior Test Consultant, Altom Consulting & Alex Rotaru, Co-owner, Altom Consulting. If you haven’t yet heard of State Model-Based Testing (SMBT) is a testing technique that allows testers to visualize their applications and to generate and automate test flows by using different models of the application under test, thus obtaining a large number of test scenarios. When certain paths of the application are changed, the benefit of using SMBT is that you will only have to modify the states and transitions that apply to that change.

This workshop rounds out the core pre-conference workshop offerings, which include a Selenium Deep Dive session led by Selenium Project Core Committer, Titus Fortner; Driving Observability with Selenium Grid 4, led by Manoj Kumar, VP, Developer Relations at LambdaTest and Selenium Project Leadership Committee member, and Advanced Appium 2.0, with Srini Sekar & Sai Krishna, Lead Consultants at Thoughtworks and long-time Appium workshop instructors.

Workshops are one of the most popular offerings at any SeleniumConf and because class sizes are limited they invariably sell-out. Early Bird ticket sales have closed, but you can still find openings for any of these awesome day-long sessions. Register today and make sure you get a seat at the Conference + Workshop session of your choice.

Wait, Wait - Where is the Fix a Bug, Become a Committer Workshop?

If you’re a long-time follower of past Selenium Conferences, or just happened to attend the July, 2022 virtual SeleniumConf, you may be familiar with the long-standing workshop offering “Fix a Bug, Become a Committer”. This workshop is a bit different in that the goal is to both enhance your own Selenium experience while offering the ability to contribute back to the project. With this, it’s not a learning session, per se, but more of a doing session, and we thought we’d take a different approach this time and make it available at no-charge (other than buying a conference ticket) to a limited number of applicants. If you are familiar with Selenium and want to extend your conference experience an extra day we encourage you to apply. Scholarship applicants (more below) are also welcome to apply.

Announcing the SeleniumConf Chicago 2023 Scholarship Program

The mission of the Selenium project is to educate the QA and developer communities about Selenium, the importance of quality assurance, and automated testing in general. Both the Selenium project and the SeleniumConf organizers very much want everyone to be able to attend the conference, but we know that not everyone’s personal or financial circumstances make this possible - so, we’re setting aside a number of free tickets, and covering travel expenses, as part of our SeleniumConf Chicago 2023 scholarship program.

The program aims to support individuals from underrepresented groups in tech and those facing economic or social hardship so they have access to SeConf content and networking opportunities. If you’re an aspiring software professional looking to use Selenium, or a current one without access to the funds to buy your ticket, you should apply. We will award tickets to people who can show that the knowledge gained will be useful for their ongoing career. The application form will be posted in January, 2023.

Ready to Go, But Your Manager Needs More Convincing?

You’ve now seen the keynotes, the current roster of speakers, and the awesome hands-on workshop descriptions, but you still need more to convince your manager? Download this “Convince Your Boss” email template and tailor it to your specific rationale using the details you’ve gleaned from this post. We’d really like to see you next March in Chicago - so register here!

BELLATRIX Test Automation Framework for C# and JAVA

Customize and extend BELLATRIX, a cross-platform .NET 6 and JAVA test automation framework to perfectly fit your needs. Start on top of hundreds of best practices features and integrations.
By Anton Angelov (@angelovstanton) |

Over the last decade, a large ecosystem of Open Source projects has sprouted up around Selenium. Selenium is often used for automating web applications for testing purposes, but it does not include a testing framework. Nowadays, Selenium Ecosystem initiatives try to give popularity to popular open-source test automation frameworks maintained by people outside of the core Selenium maintainers. One of these frameworks is BELLATRIX, invented by Anton Angelov. It has two versions - C# and Java. A testing framework is an abstraction in which common code provides generic functionality (which can be selectively overridden) for testing different aspects of our applications- UI, API, security, performance, and many others.

BELLATRIX Test Automation Framework

The first version of BELLATRIX appeared on 26 December 2017. It was available only for C# initially, but written on the new back then .NET Core, allowing the framework to be used on all major operating systems (cross-platform). One huge advantage of BELLATRIX is its cross-technology readiness. It allows you to write tests for different technologies such as Web, Mobile, Desktop, and API. In BELLATRIX, we strive for the API for all modules to be as identical as possible.

The usage is simple. We suggest cloning BELLATRIX as a GIT sub-module. Then, any customizations, tests, and project-specific plug-ins should be placed in a project outside the BELLATRIX cloned repository. This way, you can quickly update to the latest version.

BELLATRIX official website, download and releases info

BELLATRIX official C# GitHub Page

BELLATRIX official Java GitHub Page

BELLATRIX C# Documentation

BELLATRIX Java Documentation

Let’s investigate how easy it is to create your first test with BELLATRIX in 15 minutes. The sample will showcase how to create a very basic test login into a website:

  1. Open the BellatrixTestFramework.sln
  1. Under the starthere folder, find the project you prefer: web, mobile, desktop, API
  1. Open the BellatrixLoginTest.cs file. There you will find a sample test automating the login.
[TestClass]
public class LoginTestsMSTest : MSTest.WebTest
{
    public override void TestInit()
    {
       App.Navigation.Navigate("http://demos.bellatrix.solutions/my-account/");
    }

    [TestMethod]
    public void SuccessfullyLoginToMyAccount()
    {
        var userNameField = App.Components.CreateById<TextField>("username");
        var passwordField = App.Components.CreateById<Password>("password");
        var loginButton = App.Components.CreateByXpath<Button>("//button[@name='login']");

        userNameField.SetText("info@yourverybusywebsite.com");
        passwordField.SetPassword("yourverysecretp4ssw0rd$");
        loginButton.Click();

        var myAccountContentDiv = App.Components.CreateByClass<Div>("woocommerce-MyAccount-content");
        myAccountContentDiv.ValidateInnerTextContains("Hello John");

        var logoutLink = App.Components.CreateByInnerTextContaining<Anchor>("Log out");

        logoutLink.ValidateIsVisible();
        logoutLink.Click();
    }
}

All available services are available through the main App class. The Components property provides various Create methods for finding elements. They are generic, so you need to mention the type of the searched element. We have different elements because, for each of them, BELLATRIX offers various additional methods and assertions on top of native WebDriver methods. The sample code uses MSTest as the default test framework, but by changing the attributes, it will also work out of the box for NUnit. Of course, you need to change the base class namespace too.

Why BELLATRIX?

Let’s quickly list some of the essential things the framework brings to the table:

Multiple Test Environments Configuration

Every aspect of the framework can be controlled via a rich JSON configuration designed to work for many test environments. Web Project Configuration.

Customization

One of the hardest things to develop is to allow these generic frameworks to be extendable and customizable. Knowing how essential customization is, we utilize different ways to achieve it. The major one is about writing your own plug-ins.

Test Reliability

One of the biggest problems in test automation is handling timeouts and performing actions on elements that may not be on the page right now. BELLATRIX hides the complexity of searching and waiting for elements. Furthermore, when you perform an action or assertion against an element, we guarantee that once returned, it will be present.

A significant part of your tests are the assertions - checking whether some conditions are met. To handle such scenarios, we created elements Validate methods. They internally handle the whole complexity of waiting for some condition to happen.

updateCart.ValidateIsDisabled();
totalSpan.ValidateInnerTextIs("120.00€", timeout: 30, sleepInterval: 2);
messageAlert.ValidateIsNotVisible();

Complex Controls

BELLATRIX provides API that makes handling HTML tables and grids much easier HTML tables and grids.

Here is an example for asserting grid cells:

TestGrid.ForEachCell(cell => cell.AssertFontSize("14px"));
TestGrid.GetCell("Firstname", 1).ValidateInnerTextIs("Mary");
TestGrid.GetCell(0, 1).ValidateInnerTextIs("John");
TestGrid.GetCell<Employee>(cell => cell.PersonalEmail, 1).ValidateInnerTextIs("mary@hotmail.com");

There is much more complex stuff that you can do with both components so check the official documentation.

Integrations

Seamlessly integrate the framework with your existing tools and processes. Execute tests in the clouds, distribute and publish test results in reporting solutions. Maybe the most significant differentiators of the framework are its many integrations with popular tools such as Jira/qTest/Allure/ReportPortal and clouds such as AWS, Microsoft Azure, + many more. All these integrations leverage BELLATRIX plug-in architecture. For example, we have plug-ins for automatically generating/updating test cases based on our automated tests in qTest and AzureDevops or similarly creating automatic bug reports with steps to reproduce in Jira or Azure.

Dynamic Test Cases

Dynamic test cases are a unique feature in BELLATRIX, where the framework automatically generates test cases in a popular test case management system based on your automated tests. It will populate the title, description, and other necessary properties automatically. Moreover, it will generate human-readable steps and expected results. The most significant benefit is that it will keep up to date with your auto-generated test cases over time, no matter what you change in your tests. It is an excellent functionality which allows the non-technical people of your company to see what your tests are doing.

AI Validation of PDFs and Image

Azure Computer Vision is a service that can be used to extract printed and handwritten text from images and documents with mixed languages and writing styles. In contrast, Azure Form Recognizer is an AI-powered document extraction service that understands your document. You are not limited to PDFs only. You can use the same feature for extracting text from complex images. BELLATRIX comes with similar functionality based on the AWS cloud.

Email Testing

BELLATRIX offers a few utilities for email testing. There are a few scenarios where we need such integration. The first one is related to creating unique email inboxes and using them to submit various online forms. Later, we can read the emails via the services and check the content of the emails. It might be enough to verify the content via regular C#, or in some cases, we might need to interact with the email content in the browser.

There are tons of other integrations that we use on a daily basis in many big enterprise projects, such as cloud secrets management for securely storing credentials and other secrets. All BELLATRIX Integrations

Using BELLATRIX in your projects might save months/years of effort even if you have the required programming knowledge. This way, you can quickly focus on writing automated tests for your project. Usually, there are 4-6 major releases each year, including all bug fixes and new features. Check our release notes history. The framework is fully covered with over 4000 automated tests and offers rich documentation. We make sure to merge the new feature branches only when we are sure that everything is working. If some issue emerges after a major release, it is quickly fixed within a few days.

For feature requests or bug reports, you can submit them to our GitHub repositories. If you believe that the functionality you developed can be added to the CORE framework or you have a bug fix, please submit a PR so we can discuss it and potentially merge it. For anything else, you can reach us via our contact us form.

Introducing Selenium Manager

Get a working environment to run Selenium out of the box with a new beta feature!
By Boni García (@boni_gg) |

Most people’s first experience with Selenium ends up with an error message like this one:

java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.chrome.driver 
system property; for more information, see https://chromedriver.chromium.org/. The latest version can be 
downloaded from https://chromedriver.chromium.org/downloads

Then they have to search the web for instructions on what to do with the drivers they download.

Selenium: now with batteries included!

The Selenium project wants to improve the user experience, and one of the first steps is to help all users to simplify how they set up their environment. Configuring browser drivers has been for many years a task which users need to perform in order to have a working environment to run Selenium.

Setting up a browser driver once is not that complicated, but as browser release cycles got shorter, and now we have a new Chrome/Firefox/Edge version every 4-6 weeks, the task of keeping the browser driver in sync with the browser version is not that easy anymore.

Selenium Manager is a new tool that helps to get a working environment to run Selenium out of the box. Beta 1 of Selenium Manager will configure the browser drivers for Chrome, Firefox, and Edge if they are not present on the PATH.

To run a Selenium test with Selenium 4.6, you only need to have Chrome, Firefox, or Edge installed. If you already have browser drivers installed, this feature will be ignored. If you’d like to help us test it, though, delete your drivers or remove your third party driver manager and things should still “just work.” If they don’t, please file a bug report.

Future releases of Selenium Manager will eventually even download browsers if necessary.

Inspired by Open Source and the Selenium Community

Selenium Manager is not a completely new solution. Over the years, several third-party projects in the Selenium ecosystem emerged. Such as: WebDriverManager for Java, webdriver-manager for Python, webdrivers for Ruby, and WebDriverManager.Net for C#.

All these projects served as an inspiration and as a clear sign that the community needed this feature to be built-in Selenium. In addition, a survey done on January 2021 showed that most Selenium users want to get rid of the driver management problem. Plus, the fact that the driver installation page is by far the most visited one in the Selenium documentation.

Selenium Manager in detail

Selenium Manager is a CLI (Command-Line Interface) tool developed in Rust to allow cross platform execution. On its beta 1 version, Selenium Manager is invoked transparently by the Selenium bindings when no browser driver is detected on the PATH or no third party driver manager is being used.

You can also use Selenium Manager without the Selenium bindings. While we plan to do formal releases in the future, for now, the binaries can be found directly on the Selenium repository. Check the different parameters and options by running the following command:

$ ./selenium-manager --help

A quick example showing how ChromeDriver gets configured can be seen below:

$ ./selenium-manager --browser chrome
INFO	/home/boni/.cache/selenium/chromedriver/linux64/106.0.5249.61/chromedriver

If you maintain a WebDriver based project and would like to use Selenium Manager as well, join us in our community channels and we would be happy to help. Also, if you are interested in contributing, for detailed instructions and information check the project’s README.

Next steps

Selenium Manager is still under development, features will be added and bugs fixed along with each release. However, you as a member of the Selenium community are key part on the future success of this new tool. Please report ideas or bugs through our issue tracker and join the conversation through our community channels. Looking forward to your feedback!

Happy testing!

Using Java 11+ HTTP Client in Selenium 4.5.0 and beyond

We’re happy to share that starting from Selenium 4.5.0, a Java 11+ HttpClient is supported
By Puja Jagani (@pujagani) |

Current HTTP client used in Selenium

Selenium uses an HTTP client and associated WebSocket client for multiple purposes

  • To send commands to the WebDriver
  • To send commands from the Selenium client library to the Grid
  • For various Grid components to communicate with each other depending on the Grid mode
  • To create ChromeDevTools protocol and BiDi protocol sessions

Currently, Selenium uses AsyncHttpClient. AsyncHttpClient is an open-source library built on top of Netty. It allows the execution of HTTP requests and responses asynchronously. Additionally it also provides WebSocket support. Hence it is a good fit.

Why does Selenium want to move to Java 11+ HTTP Client?

While AsyncHttpClient provides the required functionality, the open-source project is not been actively maintained since June 2021. It coincides with the fact that Java 11+ provides a built-in HTTP and WebSocket client. Selenium can utilize it to replace AsyncHttpClient.

Currently, Selenium Java supports Java 8. Selenium has plans to upgrade the minimum version supported to Java 11. However, it is a sizeable effort. Aligning it with major releases and accompanied announcements is crucial to ensure the user experience is intact.

The Selenium server runs great on Java 11+ already, so while we plan to make that the minimum version in a future release, for now we plan to introduce optional components that can take advantage of modern Java releases.

So as a first step towards this move, the Java 11+ HTTP client from Selenium 4.5.0 and above.

Using Java 11+ HTTP Client in Selenium

Prerequisites:

  • Project configured to use Java 11+
  • Using Selenium 4.5.0 as a minumum version, find the latest in the downloads page.

Integrating the Java 11+ client

Java 11+ HTTP client sits in its own artifact. It can be imported into projects that use Java 11+.

Add the artifact the POM

Add the follow dependencies to your pom.xml

<dependency>
  <groupId>org.seleniumhq.selenium</groupId>
  <artifactId>selenium-java</artifactId>
  <version>4.5.0</version>
</dependency>
<dependency>
  <groupId>org.seleniumhq.selenium</groupId>
  <artifactId>selenium-http-jdk-client</artifactId>
  <version>4.5.0</version>
</dependency>

NOTE: In the dependencies above version 4.5.0 is shown, however we recommend you to check the downloads page to use the latest version released. Make sure the versions used are matching.

Set the system property

Set the system property to indicate that Java 11+ Http client needs to be used. By default, it uses the AsyncHttpClient.

 System.setProperty("webdriver.http.factory", "jdk-http-client");

You are all set up to leverage the newly supported client. The user-experience remains the unchanged. Everything else works as expected.

Using the Java 11+ client in Grid

To do that, you will need to download the selenium-http-jdk-client jar file and use the --ext flag to make it available in the Grid jar’s classpath.

The jar file can be downloaded directly from repo1.maven.org and then start the Grid in the following way:

java -Dwebdriver.http.factory=jdk-http-client -jar selenium-server-4.5.0.jar -—ext selenium-http-jdk-client-4.5.0.jar standalone

An alternative to downloading the selenium-http-jdk-client jar file is to use Coursier.

java -Dwebdriver.http.factory=jdk-http-client -jar selenium-server-4.5.0.jar —-ext $(coursier fetch -p org.seleniumhq.selenium:selenium-http-jdk-client:4.5.0) standalone

If you are using the Hub/Node(s) mode or the Distributed mode, setting the -Dwebdriver.http.factory=jdk-http-client and —-ext flags needs to be done for each one of the components.

NOTE: In the dependencies above version 4.5.0 is shown, however we recommend you to check the downloads page to use the latest version released. Make sure the versions used are matching.

Huge thanks to Simon Stewart (@shs96c) for making this possible with his contribution!

Dev and Beta Channel Browsers via Docker Selenium

Now you can test on Google Chrome, Mozilla Firefox, and Microsoft Edge on the Dev and Beta channels using Docker Selenium
By James Mortensen (@jmort253) |

The Docker Selenium browser Beta and Dev channel releases are now regularly published to Docker Hub and updated every two days. This enables testers and developers to test their applications on pre-release versions of Google Chrome, Mozilla Firefox, and Microsoft Edge before their official releases, using container tools, such as Docker. This empowers teams to stay ahead of the curve and catch potential showstoppers in their CI environment before those issues have an impact on their users.

What are “release channels”?

Here’s some background on release channels: Google, Mozilla, and Microsoft all maintain different “channels” for their respective browser releases. Most end users use the “Stable” channel. The Stable channel releases have passed rigorous testing, and these versions are considered “production-ready”. Up until now, this was the only option for a tester or developer when using Docker Selenium. Today, we’re pleased to announce teams can also test on versions of these browsers yet to be released to the general population. These are the Beta and Dev channels.

For clarity, here is Google’s description of these 3 channels from their “Chrome Release Channels” page:

Stable channel: This channel has gotten the full testing and blessing of the Chrome test team, and is the best bet to avoid crashes and other issues. It’s updated roughly every two-three weeks for minor releases, and every 6 weeks for major releases.

Beta channel: If you are interested in seeing what’s next, with minimal risk, Beta channel is the place to be. It’s updated every week roughly, with major updates coming every six weeks, more than a month before the Stable channel will get them.

Dev channel: If you want to see what’s happening quickly, then you want the Dev channel. The Dev channel gets updated once or twice weekly, and it shows what we’re working on right now. There’s no lag between major versions, whatever code we’ve got, you will get. While this build does get tested, it is still subject to bugs, as we want people to see what’s new as soon as possible.

Standalone Usage:

To use these new Docker Selenium container images in Standalone mode, run the following commands:

Chrome Beta:

$ docker run --rm -it -p 4444:4444 -p 7900:7900 --shm-size 2g selenium/standalone-chrome:beta

Chrome Dev:

$ docker run --rm -it -p 4444:4444 -p 7900:7900 --shm-size 2g selenium/standalone-chrome:dev

Firefox Beta:

$ docker run --rm -it -p 4444:4444 -p 7900:7900 --shm-size 2g selenium/standalone-firefox:beta

Firefox Dev:

$ docker run --rm -it -p 4444:4444 -p 7900:7900 --shm-size 2g selenium/standalone-firefox:dev

Edge Beta:

$ docker run --rm -it -p 4444:4444 -p 7900:7900 --shm-size 2g selenium/standalone-edge:beta

Selenium Grid

To run these container images in a Selenium Grid, we’ll use docker-compose. For instance, this example shows how to run a Selenium Grid with Chrome, Firefox, and Edge on the Beta channel:

docker-compose-v3-beta-channel.yml:

# To execute this docker-compose yml file use `docker-compose -f docker-compose-v3-beta-channel.yml up`
# Add the `-d` flag at the end for detached execution
# To stop the execution, hit Ctrl+C, and then `docker-compose -f docker-compose-v3-beta-channel.yml down`
version: "3"
services:
  chrome:
    image: selenium/node-chrome:beta
    shm_size: 2gb
    depends_on:
      - selenium-hub
    environment:
      - SE_EVENT_BUS_HOST=selenium-hub
      - SE_EVENT_BUS_PUBLISH_PORT=4442
      - SE_EVENT_BUS_SUBSCRIBE_PORT=4443

  edge:
    image: selenium/node-edge:beta
    shm_size: 2gb
    depends_on:
      - selenium-hub
    environment:
      - SE_EVENT_BUS_HOST=selenium-hub
      - SE_EVENT_BUS_PUBLISH_PORT=4442
      - SE_EVENT_BUS_SUBSCRIBE_PORT=4443

  firefox:
    image: selenium/node-firefox:beta
    shm_size: 2gb
    depends_on:
      - selenium-hub
    environment:
      - SE_EVENT_BUS_HOST=selenium-hub
      - SE_EVENT_BUS_PUBLISH_PORT=4442
      - SE_EVENT_BUS_SUBSCRIBE_PORT=4443

  selenium-hub:
    image: selenium/hub:latest
    container_name: selenium-hub
    ports:
      - "4442:4442"
      - "4443:4443"
      - "4444:4444"

To run on the more cutting edge – and hence potentially more buggy – Dev channel, simply replace the “beta” tags with “dev”.

Support

These Beta and Dev images represent pre-release browsers and WebDrivers, and they’re not guaranteed to be 100% stable. Should you run into any issues with these images, support from the Selenium community is limited and is dependent on the browser vendors. However, if you believe the issue is related to Selenium, please contact us in the various support channels.

Scaling a Kubernetes Selenium Grid with KEDA

Scaling Selenium Grid in a Kubernetes cluster with the help of KEDA
By Brandon Wolfe (@Wolfe1) |

The Issue

If you have any experience with Selenium Grid and Kubernetes you will probably run into an issue with scaling. Kubernetes (K8S) works wonders for scaling up and down applications based on their CPU and Memory usage, but it is not so straightforward when it comes down to applications like Selenium Grid.

The issue is described quite well in this blog post. But in short, the Horizontal Pod AutoScaler (HPA) that is built into Kubernetes checks (by default) for resource consumption to determine if a deployment needs to be scaled up or down. This becomes an issue for Selenium Grid for a couple reasons:

  1. The browser pods use a variable amount of resources depending on the demand of the current test. This means that all your browser pods may be in use but there isn’t enough CPU usage for the HPA to decide that a scale-up is needed, leaving tests waiting in the queue unnecessarily.
  2. When Kubernetes decides to scale down a deployment it does so (for the most part) at random. You could have 10 tests running on 20 pods and need to scale down. More than likely at least one of the pods asked to terminate will still have a test running, resulting in connection failures.

How KEDA Helps

KEDA is a free and open-source Kubernetes event-driven autoscaling solution that extends the feature set of K8S’ HPA. This is done via plugins written by the community that feed KEDA’s metrics server with the information it needs to scale specific deployments up and down.

Specifically for Selenium Grid, we have a plugin that will tie into our grid to get the information it needs. Example of the used trigger:

triggers:
  - type: selenium-grid
    metadata:
      url: 'http://selenium-grid-url-or-ip:4444/graphql'
      browserName: 'chrome'

All of this gets saved as a Scaled-Object like so:

apiVersion: keda.sh/v1alpha1
kind: ScaledObject
metadata:
  name: selenium-chrome-scaledobject
  namespace: <namespace of your browser pods>
  labels:
    deploymentName: selenium-chrome-node-deployment
spec:
  minReplicaCount: 0
  maxReplicaCount: 80
  scaleTargetRef:
    name: selenium-chrome-node-deployment
  triggers:
    - type: selenium-grid
      metadata:
        url: 'https://selenium-grid-url-or-ip:4444/graphql'
        browserName: 'chrome'

As an added bonus KEDA allows us to scale our deployments down to 0 when there is no use, something the normal out-of-the-box HPA does not allow.

Check more details at the documentation for Scaled-Object in KEDA.

A full example of how to implement this is further down in the article but KEDA solves one of our two issues. Now we can properly scale up and down based on the actual load on the Selenium Grid. Unfortunately scaling down still results in the likely possibility that a pod is still running a test and is told to terminate before it can finish.

Using PreStop and Drain

To combat this we are going to use a combination of K8s PreStop and Selenium Grid’s Drain functionality.

  • PreStop allows us to set a command or chain of commands that is run to completion before the container is told to stop.
  • Drain tells the selenium browser pod to finish its current test and then shut down.

Together these look like so in our browser pod yaml:

spec:
  template:
    spec:
      terminationGracePeriodSeconds: 3600
      ...
      ...
      containers:
        lifecycle:
          preStop:
            exec:
              command: ["/bin/sh", "-c", "curl --request POST 'localhost:5555/se/grid/node/drain' --header 'X-REGISTRATION-SECRET;'; tail --pid=$(pgrep -f '[n]ode --bind-host false --config /opt/selenium/config.toml') -f /dev/null; sleep 30s"]

Breaking this down

  • terminationGracePeriodSeconds is set to however long you wish to give your pods to gracefully terminate before being forced. In this case I give the pods 60 minutes to finish their test when asked to terminate. If you are also scaling your cluster nodes as a part of this you may need to increase the termination grace period for your cluster nodes as well.
  • When the pod is told to stop, the PreStop command is ran first.
  • We curl the localhost of our pod to tell it to drain. The pod will no longer accept new session requests and will finish its current test. More information on this can be found in the Selenium Grid documentation.
  • We then tail the internal node process that will continue to run until the node has been drained.
  • After this we give the pod 30 seconds to finish anything else before giving the full termination command.

And with that our application can now safely scale down our selenium browser deployments!

From Start to Finish

Install KEDA

  • You need to use version 2.8.0 or later, you can find the latest version number at the Selenium Grid Scaler docs.
  • kubectl apply -f https://github.com/kedacore/keda/releases/download/<Version_Number_Here>/keda-<Version_Number_Here>.yaml

Create and apply your scaled object(s)

As described earlier your scaled object will look like so:

apiVersion: keda.sh/v1alpha1
kind: ScaledObject
metadata:
  name: selenium-chrome-scaledobject
  namespace: <namespace of your browser pods>
  labels:
    deploymentName: selenium-chrome-node-deployment
spec:
  minReplicaCount: 0
  maxReplicaCount: 80
  scaleTargetRef:
    name: selenium-chrome-node-deployment
  triggers:
    - type: selenium-grid
      metadata:
        url: 'https://selenium-grid-url-or-ip:4444/graphql'
        browserName: 'chrome'

You will need one of these for every browser you wish to scale.

Things to edit:

  1. namespace should be the namespace that your selenium browser pods exist in
  2. deploymentName are the name of your browser deployment
  3. name (within spec) is also the name of your browser deployment
  4. url is the url of your selenium grid
  5. browserName is the name of the browser you are using
  6. minReplicaCount and maxReplicaCount are the min and maximum pod count you want to have

If you plan to scale with Edge you will need at least version 2.8.0 of KEDA and will need to include sessionBrowserName as well in the trigger metadata:

triggers:
    - type: selenium-grid
      metadata:
        url: 'https://selenium-grid-url-or-ip:4444/graphql'
        browserName: 'MicrosoftEdge'
        sessionBrowserName: 'msedge'

This is due to a name change between the Edge sessions in the queue and the active sessions and is addressed through this pull request.

Once you have that ready just save it as a yaml file and apply with:

  • kubectl apply -f ./<scaled-object-file-name>.yaml --namespace=<browser_namespace>

Add PreStop commands to your browser pods

  1. Set your terminationGracePeriodSeconds of your deployment to whatever the maximum time you wish to give the pods in order to terminate gracefully. Again you may need to also increase the grace period for your nodepool as well which will vary depending on your K8s provider.
  2. Add the PreStop command to the container lifecycle spec:
spec:
  template:
    spec:
      terminationGracePeriodSeconds: 3600
      ...
      ...
      containers:
        lifecycle:
          preStop:
            exec:
              command: ["/bin/sh", "-c", "curl --request POST 'localhost:5555/se/grid/node/drain' --header 'X-REGISTRATION-SECRET;'; tail --pid=$(pgrep -f '[n]ode --bind-host false --config /opt/selenium/config.toml') -f /dev/null; sleep 30s"]

That is it, your Selenium Grid pods should now scale up and down properly without any lost sessions!

Removing Legacy Protocol Support

Selenium 4.3 will only support W3C compliant WebDriver syntax
By Titus Fortner (@titusfortner) |

The Selenium team prides itself on how seriously it takes backwards compatibility. A lot of care has gone into the Java bindings, especially, to ensure very few breaking changes over the years. There is Selenium code written 15 years ago that can still run with Selenium 4 libraries! Providing this exceptional amount of support comes with a large maintenance burden, though, and we need to be able to properly meet the needs of the vast majority of our userbase.

TL/DR:

  • Support for the legacy JSON Wire Protocol will be removed from Java Selenium 4.3 (other languages have already removed this support)
  • Protocol conversions will stop in Selenium 4.3 Grid
  • You can ensure your sessions are W3C compliant by using Browser Options classes instead of the deprecated Desired Capabilities classes (and avoid using “set capability” methods directly)
  • If you rely on the current protocol conversion functionality, and it works for you, you can continue to use it with Selenium Grid 4.2

By far the biggest challenge in the past seven years of Selenium development has been transitioning the underlying implementation from the legacy JSON Wire Protocol to the new standardized W3C WebDriver Protocol. Because the WebDriver specification was being actively developed at the time, Selenium 3 supported both protocols simultaneously. We implemented “handshake” code to determine which protocol to use. When starting a session, Selenium would package the provided capabilities in both legacy and W3C formats, send them to the driver/server, and use whichever protocol was returned. This worked well for the most part. For many users, no changes were necessary to get W3C compliant sessions from new browsers (Firefox 47+ and Chrome 75+).

For the Java bindings, it was decided to take this approach one step further. Instead of just sending along what was provided in both formats, the code converted capabilities from the legacy protocol to the W3C protocol on behalf of the user. The Selenium Grid makes use of this code, so, regardless of which client language sends legacy capabilities to it, the Grid translates it to the W3C protocol for communication with the driver and then re-translates the results back to the legacy protocol. Because the code must make some assumptions and guesses for this to work, there are a lot of frustrating edge cases.

For Selenium 4.0, the Ruby, JavaScript, and .NET bindings, each removed the handshake code, so no legacy commands are used. Due to some issues that couldn’t be resolved before freezing the 3.x code, Python is waiting until Selenium 4.3 to remove its handshake code. The Selenium team intended to continue to support both protocols in the Grid and Java bindings throughout the 4.x releases, but running test suites written for Selenium 2 on the Selenium 4 Grid resulted in a larger than expected number of failures. Half a dozen bugs were discovered, some with a large effect.

The code in question is sufficiently complex that fixing the bugs without causing new problems would be a significant challenge. As such, we’ve decided to start simplifying the code base again by explicitly not supporting capabilities and commands from the legacy protocol in any of the Selenium codebase. If you are using the latest version of Java Selenium, everything that will be removed has already been marked deprecated, so double-check your usage to ensure there aren’t any surprises.

If you’re interested in the nitty-gritty details of some of the issues we found exploring this problem, you can look at the discussion in Selenium Issue #10374.

Locate your locators - Python bindings changes upcoming

Updating your locators for changes in the Python bindings in Selenium 4
By Josh Grant (@joshin4colours) |

In real estate, the mantra for finding a new house or office space is “location, location, location!”. It could be said that when working with Selenium, a critical aspect of writing tests is “locators, locators, locators!”. Having a robust locator strategy - in your app under test and in your test framework - is highly important for effective testing.

If you are a Pythonista like myself and using Selenium for your test automation, then there are some important changes coming to how locators are defined and used.

Sometime after Selenium 4.2, the Python Selenium bindings will remove locator-specific methods for finding elements. This means that the methods

driver.find_element_by_id("some_id")
driver.find_element_by_name("some_name")
driver.find_element_by_tag_name("some_tag")
driver.find_element_by_css_selector("some_selector")
driver.find_element_by_class_name("some_class")
driver.find_element_by_link_text("some_text")
driver.find_element_by_partial_link_text("some_other_text")
driver.find_element_by_xpath("some_xpath")

will be removed. All of these methods are in fact special cases of

driver.find_element(By_object, "some_locator")

so this approach is now preferred (required, even) with the Python bindings.

Note that it’s good practice to use the By object which has specific values for using particular locator strategies. For example, this line

driver.find_element_by_id("submit_button").click()
driver.find_element_by_css_selectors('.myelement child').text

becomes

driver.find_element(By.ID, "submit_button").click()
driver.find_element(By.CSS_SELECTOR, '.myelement child').text

If you’re really desperate however you can use strings instead of the By object:

driver.find_element('id', "submit_button").click()
driver.find_element('css selector', '.myelement child').text

If you have any plans to upgrade your Selenium client for your Python tests to recent versions of Selenium 4, definitely keep these changes in mind. It’s a good time to update your locator strategy and structure.

IE Mode in Edge supported by IEDriver

Support for IE Mode in Edge with IEDriver
By David Burns (@AutomatedTester) |

With the retirement of Internet Explorer 11 (IE 11) later this year, the folks in Redmond have helped the Selenium project with getting IE Mode in Microsoft Edge working in IEDriver.

IE 11 is due to retire on 15 June 2022 for certain versions of Windows 10. After this date, the Selenium project recommends that you test your IE sites with IE Mode in Microsoft Edge. The Selenium Project will not remove support for IE 11 when it retires but we will not actively fix issues as we have done with previous versions of IE.

The Microsoft Edge team have committed to supporting IE Mode in Edge until 2029 when support for Windows 10 is retired.

Microsoft have written up all the details on how to use and how to migrate your site and we recommend you go read and follow their steps to make sure you’re ready.
