Selenium WebDriver Technology & Digital Applications 2 β Questions and Answers
Question 1: Which Selenium WebDriver method is used to switch the driver's context to an iframe?
- driver.switchTo().frame() (Correct answer)
- driver.switchTo().window()
- driver.switchTo().alert()
- driver.switchTo().defaultContent()
Correct answer: driver.switchTo().frame()
driver.switchTo().frame() switches the WebDriver context into the specified iframe so you can interact with its elements.
Question 2: What does the WebDriver method driver.getWindowHandles() return?
- A Set of all open browser window/tab handles (Correct answer)
- The title of the current window
- The URL of the active window
- A List of all open browser window/tab handles
Correct answer: A Set of all open browser window/tab handles
driver.getWindowHandles() returns a Set<String> containing the handles of all currently open browser windows or tabs.
Question 3: Which class in Selenium WebDriver is used to simulate keyboard and mouse actions like hover, drag-and-drop, and right-click?
- Actions (Correct answer)
- Robot
- Keys
- EventFiringWebDriver
Correct answer: Actions
The Actions class provides an API for building complex user interaction sequences such as hover, drag-and-drop, and context clicks.
Question 4: What is the role of DesiredCapabilities in Selenium WebDriver?
- To specify browser properties and settings before launching a session (Correct answer)
- To store test results after a session
- To define locator strategies for finding elements
- To configure wait timeouts for elements
Correct answer: To specify browser properties and settings before launching a session
DesiredCapabilities allows testers to configure browser type, version, platform, and other settings before starting a WebDriver session.
Question 5: Which Selenium component acts as a proxy, translating WebDriver commands into browser-specific instructions?
- Browser driver (e.g., ChromeDriver, GeckoDriver) (Correct answer)
- Selenium Grid Hub
- Selenium IDE
- TestNG framework
Correct answer: Browser driver (e.g., ChromeDriver, GeckoDriver)
Browser-specific drivers like ChromeDriver and GeckoDriver translate the WebDriver protocol commands into native browser automation calls.
Question 6: What does driver.manage().window().maximize() do in Selenium WebDriver?
- Maximizes the browser window to fill the screen (Correct answer)
- Opens a new browser window
- Sets the window to full-screen mode
- Resizes the window to 1920x1080
Correct answer: Maximizes the browser window to fill the screen
driver.manage().window().maximize() enlarges the browser window to the maximum size available on the current display.
Question 7: Which assertion type in TestNG would cause the test suite to immediately stop execution upon failure?
- Assert (hard assertion) (Correct answer)
- SoftAssert
- VerifyAssert
- LazyAssert
Correct answer: Assert (hard assertion)
Hard assertions using Assert class stop test execution immediately when the condition fails, unlike SoftAssert which collects failures and reports them at the end.
