Core Selenium Interview Questions and Answers

What is Selenium? Selenium is an open-source automation testing framework used to test web applications across browsers. It is widely used for regression, smoke, and functional testing.

What are the main components of Selenium? Selenium has Selenium IDE, Selenium WebDriver, and Selenium Grid. Among them, WebDriver is the most commonly used component for browser automation.

What is Selenium WebDriver? Selenium WebDriver is a powerful browser automation API that interacts directly with browsers through browser-specific drivers such as ChromeDriver and GeckoDriver.

What are the advantages of Selenium? It is open-source, supports multiple browsers, works with different languages, and is highly suitable for web automation testing.

What are the limitations of Selenium? Selenium is designed for web applications and does not support native mobile or desktop app automation without additional tools. It also needs browser drivers and proper synchronization with the application under test.

Selenium WebDriver Interview Questions

• findElement() vs findElements(): findElement returns a single element and throws an exception if not found, while findElements returns a list and returns an empty list when no match exists.
• How do you handle alerts in Selenium?: Use Alert interface methods like accept(), dismiss(), getText(), and sendKeys().
• How do you manage multiple windows?: Use getWindowHandles() and switchTo().window() to move between browser windows.
• How do you handle frames?: Use switchTo().frame() by index, name, ID, or WebElement.
• How do you work with dropdowns?: Use Select class for standard HTML dropdown elements.
• How do you capture screenshots?: Use TakesScreenshot and FileHandler.copy to save screenshot files.
• How do you manage cookies?: Use driver.manage().getCookies(), addCookie(), deleteCookie(), and deleteAllCookies().

Selenium Waits, XPath and Java Questions

What is implicit wait? Implicit wait is a default wait time applied to all element searches in a WebDriver instance.

What is explicit wait? Explicit wait waits until a specific condition is met before continuing execution, such as element visibility or clickable state.

What is WebDriverWait? WebDriverWait is part of Selenium’s explicit wait API and allows waiting for specific expected conditions like visibilityOfElementLocated or elementToBeClickable.

What is FluentWait? FluentWait allows custom polling interval and ignores specific exceptions while waiting for a condition to be satisfied.

What is XPath? XPath is a query language used to navigate and select elements in an HTML or XML document. It is commonly used in Selenium to locate dynamic or complex elements.

What is the difference between absolute and relative XPath? Absolute XPath starts from the root and is often fragile, while relative XPath uses meaningful paths and is more maintainable.

What are common XPath functions? functions like contains(), starts-with(), text(), parent, child, ancestor, descendant, following-sibling, preceding-sibling are commonly used in Selenium automation.

What is the difference between String and StringBuilder? String is immutable, while StringBuilder is mutable and preferred for frequent string modifications in Java automation code.

What is OOP? Object-oriented programming focuses on classes, objects, inheritance, encapsulation, polymorphism, and abstraction.

TestNG, Cucumber and Selenium Framework Questions

What is TestNG? TestNG is a testing framework for Java that provides annotations, grouping, parallel execution, dependency testing, listeners, and powerful reporting.

What are common TestNG annotations? @Test, @BeforeMethod, @AfterMethod, @BeforeClass, @AfterClass, @BeforeSuite, @AfterSuite, and @DataProvider are commonly used.

What is the Page Object Model? POM is a design pattern where each page is represented by a class, helping keep test code cleaner and reducing duplication.

What is Cucumber? Cucumber is a BDD tool that allows behavior-driven scenarios written in plain English using feature files and step definitions.

What is a Scenario Outline? A Scenario Outline is used to run the same scenario logic multiple times with different examples.

What is the benefit of a hybrid framework? A hybrid framework combines the best parts of data-driven, keyword-driven, and POM-based approaches to improve reusability and maintainability.
