Toml配置选项
CLI选项 中 显示的所有选项都可以通过 TOML 文件进行配置. 此页面显示不同Grid组件的配置示例.
请注意, 如果修改或添加了选项, 但尚未记录, 则此文档可能已过时. 如果您遇到这种情况, 请查看 “配置帮助” 部分, 并随时向我们发送更新此页面的请求.
概述
Selenium Grid对配置文件使用 TOML 格式. 配置文件由多个部分组成, 每个部分都有选项及其各自的值.
有关详细的使用指南, 请参阅TOML文档 . 如果出现解析错误, 请使用 TOML linter 验证配置.
一般配置结构具有以下模式:
[section1]
option1="value"
[section2]
option2=["value1","value2"]
option3=true
下面是一些使用Toml文件配置的 Grid组件示例, 该组件可以 从下面的方式开始:
java -jar selenium-server-<version>.jar <component> --config /path/to/file/<file-name>.toml
单机模式
单机服务器, 在端口4449上运行, 新会话请求超时500秒.
[server]
port = 4449
[sessionqueue]
session-request-timeout = 500
特定浏览器和最大会话数限制
默认情况下仅启用Firefox 和Chrome的单机服务器或节点.
[node]
drivers = ["chrome", "firefox"]
max-sessions = 3
配置和定制驱动程序
具有定制驱动程序的单机或节点服务器, 允许使用Firefox试用或者每日构建的功能, 并且有不同的浏览器版本.
[node]
detect-drivers = false
[[node.driver-configuration]]
max-sessions = 100
display-name = "Firefox Nightly"
stereotype = "{\"browserName\": \"firefox\", \"browserVersion\": \"93\", \"platformName\": \"MAC\", \"moz:firefoxOptions\": {\"binary\": \"/Applications/Firefox Nightly.app/Contents/MacOS/firefox-bin\"}}"
[[node.driver-configuration]]
display-name = "Chrome Beta"
stereotype = "{\"browserName\": \"chrome\", \"browserVersion\": \"94\", \"platformName\": \"MAC\", \"goog:chromeOptions\": {\"binary\": \"/Applications/Google Chrome Beta.app/Contents/MacOS/Google Chrome Beta\"}}"
[[node.driver-configuration]]
display-name = "Chrome Dev"
stereotype = "{\"browserName\": \"chrome\", \"browserVersion\": \"95\", \"platformName\": \"MAC\", \"goog:chromeOptions\": {\"binary\": \"/Applications/Google Chrome Dev.app/Contents/MacOS/Google Chrome Dev\"}}"
webdriver-executable = '/path/to/chromedriver/95/chromedriver'
带Docker的单机或节点
单机或节点服务器能够在Docker容器中运行每个新会话.
禁用驱动程序检测,
则最多有2个并发会话.
原型配置需要映射一个Docker映像,
Docker的守护进程需要通过http/tcp公开.
此外，可以通过 devices 属性定义在主机上可访问的哪些设备文件将在容器中可用。
有关 docker 设备映射如何工作的更多信息，请参阅 docker 文档。
[node]
detect-drivers = false
max-sessions = 2
[docker]
configs = [
"selenium/standalone-chrome:93.0", "{\"browserName\": \"chrome\", \"browserVersion\": \"91\"}",
"selenium/standalone-firefox:92.0", "{\"browserName\": \"firefox\", \"browserVersion\": \"92\"}"
]
#Optionally define all device files that should be mapped to docker containers
#devices = [
# "/dev/kvm:/dev/kvm"
#]
url = "http://localhost:2375"
video-image = "selenium/video:latest"
将命令中继到支持WebDriver的服务端点
连接到支持WebDriver外部服务 的Selenium Grid非常有用. 这种服务的一个例子可以是 云提供商或Appium服务器. 这样, Grid可以实现对本地不存在的平台和版本的更多覆盖.
下面是一个将Appium服务器连接到Grid的示例.
[node]
detect-drivers = false
[relay]
# Default Appium/Cloud server endpoint
url = "http://localhost:4723/wd/hub"
status-endpoint = "/status"
# Stereotypes supported by the service. The initial number is "max-sessions", and will allocate
# that many test slots to that particular configuration
configs = [
"5", "{\"browserName\": \"chrome\", \"platformName\": \"android\", \"appium:platformVersion\": \"11\"}"
]
启用基本身份验证
通过配置包含用户名和密码的 路由器/集线器/单机的方式, 可以使用这样的基本身份验证保护Grid. 加载Grid UI或者开始一个新的会话时 需要此用户/密码组合.
[router]
username = "admin"
password = "myStrongPassword"
下面是一个Java示例, 演示如何使用配置的用户和密码启动会话.
URL gridUrl = new URL("http://admin:myStrongPassword@localhost:4444");
RemoteWebDriver webDriver = new RemoteWebDriver(gridUrl, new ChromeOptions());
Setting custom capabilities for matching specific Nodes
Important: Custom capabilities need to be set in the configuration in all Nodes. They also need to be included always in every session request.
[node]
detect-drivers = false
[[node.driver-configuration]]
display-name = "firefox"
stereotype = '{"browserName": "firefox", "platformName": "macOS", "browserVersion":"96", "networkname:applicationName":"node_1", "nodename:applicationName":"app_1" }'
max-sessions = 5
Here is a Java example showing how to match that Node
FirefoxOptions options = new FirefoxOptions();
options.setCapability("networkname:applicationName", "node_1");
options.setCapability("nodename:applicationName", "app_1");
options.setBrowserVersion("96");
options.setPlatformName("macOS");
WebDriver driver = new RemoteWebDriver(new URL("http://localhost:4444"), options);
driver.get("https://selenium.dev");
driver.quit();
Enabling Managed downloads by the Node.
The Node can be instructed to manage downloads automatically. This will cause the Node to save all files that were downloaded for a particular session into a temp directory, which can later be retrieved from the node. To turn this capability on, use the below configuration:
[node]
enable-managed-downloads = true
Refer to the CLI section for a complete example.
