Driver Service Class

The Service classes are for managing the starting and stopping of local drivers. They cannot 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().build();
    driver = new ChromeDriver(service);

    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 cannot update Selenium or have an advanced use case, here is how to specify the driver location:

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

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

    service = webdriver.ChromeService(executable_path=chromedriver_bin)

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

    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

    ChromeDriverService service = new ChromeDriverService.Builder().usingPort(1234).build();

    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
