Driver Service Class

服务类用于管理驱动程序的启动和停止. They can not be used with a Remote WebDriver session.

Service classes allow you to specify information about the driver, like location and which port to use. They also let you specify what arguments get passed to the command line. Most of the useful arguments are related to logging.

Default Service instance

To start a driver with a default service instance:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        ChromeDriverService service = new ChromeDriverService.Builder()
                .usingDriverExecutable(getDriverLocation())
                .build();

    service = webdriver.ChromeService()
    driver = webdriver.Chrome(service=service)

            var service = ChromeDriverService.CreateDefaultService();
            driver = new ChromeDriver(service);

    service = Selenium::WebDriver::Service.chrome
    @driver = Selenium::WebDriver.for :chrome, service: service

Driver location

Note: If you are using Selenium 4.6 or greater, you shouldn’t need to set a driver location. If you can not update Selenium or have an advanced use case here is how to specify the driver location:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

                .usingDriverExecutable(getDriverLocation())

    service = webdriver.ChromeService(executable_path=chromedriver_path)

            var service = ChromeDriverService.CreateDefaultService(GetDriverLocation());

    service.executable_path = driver_path

Driver port

If you want the driver to run on a specific port, you may specify it as follows:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

                .usingPort(1234)

    service = webdriver.ChromeService(port=1234)

            service.Port = 1234;

    service.port = 1234

Logging

Logging functionality varies between browsers. Most browsers allow you to specify location and level of logs. Take a look at the respective browser page:

• Chrome
• Edge
• Firefox
• Internet Explorer
• Safari
