Question 1

What is Selenium WebDriver and how does it work?

Accepted Answer

Selenium WebDriver is a web automation framework that allows testing of web applications by directly communicating with the browser using its native support.

Question 2

What are different types of locators in Selenium?

Accepted Answer

Selenium provides various locators such as ID, Name, Class Name, Tag Name, CSS Selector, Link Text, Partial Link Text, and XPath to identify web elements.

Question 3

What is the difference between implicit and explicit waits in Selenium?

Accepted Answer

Implicit waits apply a default time delay globally for all elements, while explicit waits are used for specific elements based on defined conditions.

Question 4

What are common test automation frameworks used with Selenium?

Accepted Answer

Common frameworks include Data-Driven, Keyword-Driven, Hybrid, and Behavior-Driven Development (BDD) with tools like TestNG, JUnit, and Cucumber.

Question 5

How do you handle file uploads in Selenium?

Accepted Answer

Use sendKeys with the file path to the input element of type 'file'. Third-party tools like AutoIt or Robot class are used if it's a native OS dialog.

Question 6

What is the difference between driver.close() and driver.quit()?

Accepted Answer

close() closes the current browser window. quit() closes all windows and terminates the WebDriver session.

Question 7

How do you handle multiple windows/tabs in Selenium?

Accepted Answer

Use getWindowHandles() to get all window handles, then switchTo().window(handle) to switch.

Question 8

What is the purpose of the Actions class in Selenium?

Accepted Answer

The Actions class provides methods for complex user interactions like mouse hover, drag and drop, double-click, and keyboard actions.

Question 9

How do you handle JavaScript alerts, prompts, and confirms?

Accepted Answer

Switch to alert using driver.switchTo().alert(), then use accept(), dismiss(), getText(), or sendKeys().

Question 10

What is the difference between relative and absolute XPath?

Accepted Answer

Absolute XPath starts from the root (html) and is brittle. Relative XPath starts from any element (using //) and is more resilient to DOM changes.
