String href = element.getAttribute("href"); // Attribute valueQue 32. How do you handle a dropdown menu in Selenium WebDriver?
Answer:
Use the Select class to interact with dropdowns, selecting options by value, index, or visible text.
Select dropdown = new Select(driver.findElement(By.id("dropdown")));
dropdown.selectByVisibleText("Option 1");Que 33. What is an implicit wait in Selenium WebDriver?
Answer:
Implicit wait sets a default time for WebDriver to wait for elements to appear before throwing an error. It applies globally to all element searches.
driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10));Que 34. How do you navigate back and forward in a browser using Selenium?
Answer:
Use the navigate() method with back() or forward() to move through browser history.
driver.navigate().back();
driver.navigate().forward();Que 35. What is the purpose of the isDisplayed() method in Selenium?
Answer:
The isDisplayed() method checks if an element is visible on the page, returning true if visible, false otherwise.
WebElement element = driver.findElement(By.id("elementId"));
boolean visible = element.isDisplayed();Que 36. How do you handle a checkbox in Selenium WebDriver?
Answer:
Locate the checkbox and use click() to toggle its state or isSelected() to check if it’s selected.
WebElement checkbox = driver.findElement(By.id("checkboxId"));
if (!checkbox.isSelected()) {
checkbox.click();
}Que 37. What is the purpose of the Actions class in Selenium?
Answer:
The Actions class handles advanced user interactions like mouse hovers, drag-and-drop, or keyboard inputs, chaining multiple actions.
Actions actions = new Actions(driver);
actions.moveToElement(driver.findElement(By.id("elementId"))).click().build().perform();Que 38. How do you take a screenshot in Selenium WebDriver?
Answer:
Use the TakesScreenshot interface to capture a screenshot, saving it as a file.
File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(screenshot, new File("screenshot.png"));Que 39. What is the purpose of the WebElement interface in Selenium?
Answer:
The WebElement interface represents an HTML element, providing methods like click(), sendKeys(), and getText() to interact with or retrieve data from elements.
Que 40. How do you verify if an element is enabled in Selenium?

Que 61. How do you handle dynamic web elements with changing attributes in Selenium?
Answer:
Use flexible locators like XPath or CSS Selector with partial matches or DOM traversal. For example, use contains() in XPath for dynamic IDs or classes. Regularly update locators and implement retry logic with WebDriverWait to handle timing issues.
WebElement element = new WebDriverWait(driver, Duration.ofSeconds(10))
.until(ExpectedConditions.elementToBeClickable(By.xpath("//*[contains(@id, 'dynamic')]")));Que 62. What is the difference between explicit and implicit waits in Selenium?
Answer:
Implicit wait sets a global timeout for all element searches, applied automatically. Explicit wait (WebDriverWait) waits for specific conditions (e.g., element visibility) with customizable timeouts. Explicit waits are preferred for precise control and better performance.
// Implicit wait
driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10));

WebElement element = driver.findElement(By.id("insideFrame"));
element.click();
driver.switchTo().defaultContent();Que 65. What is the Page Object Model (POM) in Selenium, and how do you implement it?
Answer:
POM is a design pattern where each web page is represented as a class, with elements and actions as methods, improving maintainability. Use annotations like @FindBy with PageFactory.
public class LoginPage {
@FindBy(id = "username") private WebElement username;
public void login(String user, String pass) {
username.sendKeys(user);
driver.findElement(By.id("password")).sendKeys(pass);
driver.findElement(By.id("submit")).click();
}
}Que 66. How do you handle multiple browser windows in Selenium?

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("document.getElementById('element').click();");Que 68. How do you handle stale element exceptions in Selenium?
Answer:
StaleElementReferenceException occurs when an element is no longer in the DOM. Use WebDriverWait with ExpectedConditions.stalenessOf() or retry logic to relocate the element.
WebElement element = driver.findElement(By.id("element"));
new WebDriverWait(driver, Duration.ofSeconds(10))
.until(ExpectedConditions.stalenessOf(element));
element = driver.findElement(By.id("element")); // RelocateQue 69. What is the role of TestNG in Selenium test automation?

@Test
public void testLogin() {
driver.get("https://example.com");
Assert.assertTrue(driver.getTitle().contains("Login"));
}Que 70. How do you handle file uploads in Selenium?
Answer:
For <input type="file">, use sendKeys() to provide the file path. For non-standard uploads, use tools like AutoIt or Robot class.
WebElement upload = driver.findElement(By.id("fileInput"));
upload.sendKeys("C:\\path\\to\\file.txt");Que 71. How do you automate testing for a drag-and-drop feature in Selenium?
Answer:

DesiredCapabilities caps = new DesiredCapabilities();
caps.setBrowserName("chrome");
WebDriver driver = new RemoteWebDriver(new URL("http://hub-url"), caps);Que 74. How do you run Selenium tests in headless mode?
Answer:
Use browser options (e.g., ChromeOptions) to enable headless mode, running tests without a visible browser UI.
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
WebDriver driver = new ChromeDriver(options);Que 75. How do you integrate Selenium with a CI/CD pipeline?
Answer:
Integrate Selenium with tools like Jenkins or GitHub Actions by adding test scripts to the pipeline, using Maven/Gradle for dependencies, and running tests in headless mode. Generate reports with TestNG or Allure for visibility.
# Example GitHub Actions
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- run: mvn testQue 76. How do you handle AJAX calls in Selenium tests?

wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("ajaxElement")));Que 77. How do you perform cross-browser testing with Selenium?
Answer:
Use a test framework like TestNG and configure WebDriver for multiple browsers (e.g., Chrome, Firefox). Run tests in parallel with Selenium Grid or cloud services like BrowserStack.
@Test
public void testCrossBrowser(@Parameter("browser") String browser) {
WebDriver driver = browser.equals("chrome") ? new ChromeDriver() : new FirefoxDriver();
// Test logic
}Que 78. How do you handle timeouts in Selenium WebDriver?
Answer:
Set timeouts using driver.manage().timeouts() for page load, script execution, or implicit waits. Use explicit waits for specific conditions.

driver.manage().timeouts().scriptTimeout(Duration.ofSeconds(10));Que 79. How do you automate testing for a web table in Selenium?
Answer:
Locate the table with a locator, iterate through rows/columns using findElements with XPath or CSS, and extract data with getText().
List<WebElement> rows = driver.findElements(By.xpath("//table[@id='tableId']/tr"));
for (WebElement row : rows) {
List<WebElement> cells = row.findElements(By.tagName("td"));
for (WebElement cell : cells) {
System.out.println(cell.getText());
}
}Que 80. How do you manage test data in Selenium for reusable tests?
Answer:
Use external files (e.g., Excel, JSON) or @DataProvider in TestNG to supply test data. Read data with libraries like Apache POI or Gson, ensuring tests are data-driven and reusable.
@DataProvider(name = "loginData")
public Object[][] getData() {
return new Object[][] { {"user1", "pass1"}, {"user2", "pass2"} };
}
@Test(dataProvider = "loginData")
public void testLogin(String username, String password) {
// Test logic
}
