How can DesiredCapabilities be utilized to customize the behavior of the browser driver, such as setting timeouts or enabling/disabling features?

Hey Saanvi,

DesiredCapabilities in Selenium WebDriver are key/value pairs that configure browser behavior. They enable users to customize WebDriver instances, such as setting the FirefoxDriver path for non-default installations. Detailed documentation is available for DesiredCapabilities and specific drivers like ChromeDriver.

Hey Saanvi,

Here you must remember some pointers , below i am sharing you the example along with the pointers to consider when adding desired capabilities.

  • It is a class in org.openqa.selenium.remote.DesiredCapabilities package

  • It gives the facility to set the properties of the browser. Such as to set BrowserName, Platform, and Version of Browser.

  • Mostly, the DesiredCapabilities class is used when we use Selenium Grid.

  • We have to execute mutiple TestCases on multiple Systems with different browser with Different version and Different Operating System.

Example:

WebDriver driver;
String baseUrl , nodeUrl;
baseUrl = "https://www.facebook.com";
nodeUrl = "http://192.168.10.21:5568/wd/hub";

DesiredCapabilities capability = DesiredCapabilities.firefox();
capability.setBrowserName("firefox");
capability.setPlatform(Platform.WIN8_1);

driver = new RemoteWebDriver(new URL(nodeUrl),capability);
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(2, TimeUnit.MINUTES);

I hope you understood the concept.
