Basic Selenium Interview Questions for Freshers

These are the most common entry-level Selenium interview questions asked to beginners and freshers. Interviewers use these questions to check your understanding of Selenium fundamentals, locator strategies, WebDriver basics, and simple automation concepts.

Let’s start with the simple ones.

1. What is Selenium?

Selenium is an open-source automation tool used to test web applications. It supports multiple programming languages and browsers, making it one of the most popular automation testing tools in the industry.

2. What is Selenium WebDriver?

Selenium WebDriver is a core component for automating browser actions. It interacts directly with the browser and performs operations such as clicking, typing, navigating, and fetching element details.

3. What are Locators in Selenium?

Locators are used to find web elements on a page. Familiar locators include ID, Name, Class, CSS Selector, XPath, and LinkText. Locators help WebDriver interact with elements.

4. What is the difference between findElement() and findElements()?

findElement() returns the first matching web element or throws an error if not found. findElements() returns a list of matching elements and does not throw an error even if elements are missing.

5. What is XPath?

XPath is a locator used to find elements based on their HTML structure. It supports navigating through elements using attributes, text, and dynamic patterns.

6. What are CSS Selectors?

CSS Selectors help locate elements using CSS patterns. They are faster than XPath in many cases and allow identifying elements using class, ID, attribute values, and hierarchy.

7. What is the difference between XPath and CSS Selector?

XPath allows navigating both forward and backward in the DOM, while CSS Selectors are generally faster but support only forward traversal. CSS is simpler, while XPath is better suited to complex elements.

8. What is Implicit Wait in Selenium?

Implicit Wait tells WebDriver to wait for a particular time before throwing “No Such Element” errors. It applies globally to all elements and helps improve performance on slow-loading pages.

9. What is Explicit Wait in Selenium?

Explicit Wait is applied to specific elements or conditions. It waits until the element becomes clickable, visible, or present. It gives more control than implicit Wait.

10. What is a WebElement in Selenium?

A WebAn Element represents an element on a web page, such as an input box, button, link, or dropdown. WebDriver interacts with elements using WebElement methods like click(), sendKeys(), and getText().

11. What browsers does Selenium support?

Selenium supports all major browsers like Chrome, Firefox, Edge, Safari, and Opera. Each browser uses its own driver, such as ChromeDriver or GeckoDriver.

12. What are the advantages of Selenium?

Selenium is open-source, supports multiple languages, works across browsers, integrates with frameworks, and supports parallel execution. It is flexible and widely used in automation testing.

13. What is Selenium IDE?

Selenium IDE is a record-and-playback tool mainly used for quick testing and learning. It is not used in professional projects but is helpful for beginners.

14. Can Selenium automate desktop applications?

No. Selenium only automates web applications. For desktop apps, tools like AutoIt or WinAppDriver are used.

15. What languages can Selenium work with?

Selenium supports Java, Python, C#, Ruby, JavaScript, and Kotlin. Most companies prefer Java or Python for automation frameworks.

Selenium WebDriver Interview Questions

These questions help interviewers understand how well you know browser automation, WebDriver commands, waits, navigation, and element interaction. Most Selenium interviews include these questions because WebDriver is the core tool used in real automation projects.

Let’s go through the commonly asked WebDriver questions.

16. What is WebDriver in Selenium?

WebDriver is the leading Selenium automation engine. It directly controls the browser by communicating with browser drivers such as ChromeDriver or GeckoDriver and performing user actions.

17. How does Selenium WebDriver work internally?

WebDriver sends commands to the browser driver. The driver converts these commands into actions and returns results to WebDriver. This flow creates real browser automation.

18. What is the difference between get() and navigate().to()?

get() loads a new web page directly. navigate().to() allows moving through the browser history and supports forward/backward navigation, as well as loading URLs.

19. How do you click a button in Selenium?

You first identify the element using a locator, store it in a WebElement, and then call click().
Example:
driver.findElement(By.id(“login”)).click();

20. How do you enter text in a text box in Selenium?

Use sendKeys() on the WebElement.
Example:
driver.findElement(By.name(“email”)).sendKeys(“abc@test.com”);

21. What are the different types of waits in Selenium?

There are two main waits: Implicit Wait and Explicit Wait. Implicit Wait applies globally, while Explicit Wait waits for specific conditions, such as visibility or clickability.

22. What is Fluent Wait in Selenium?

Fluent Wait allows you to define custom polling intervals and handle exceptions while waiting for an element. It offers more flexibility than implicit and explicit waits.

23. How do you handle dropdowns in Selenium?

Use the Select class.
Example:
Select s = new Select(element);
You can select by index, value, or visible text.

24. How do you handle checkboxes and radio buttons?

Locate the element and use click().
You can also check if it’s selected using isSelected() before performing a click.

25. How do you handle alerts in Selenium?

Use the Alert interface.
Example:
driver.switchTo().alert().accept();
You can also reject or fetch alert text.

26. How do you switch between frames in Selenium?

Use:
driver.switchTo().frame(index)
driver.switchTo().frame(name/id)
driver.switchTo().frame(WebElement)
You must switch back using defaultContent().

27. How do you handle multiple windows or tabs?

Use:
driver.getWindowHandles()
Then switch using:
driver.switchTo().window(windowID);

28. How do you perform mouse actions in Selenium?

Use the Actions class for hover, drag-and-drop, right-click, and double-click.
Example:
Actions a = new Actions(driver);

29. How do you take a screenshot in Selenium?

Use the TakesScreenshot interface.
Example:
((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);

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

close() closes the current browser window, while quit() closes all browser windows opened by WebDriver and ends the session.

31. How do you maximize the browser window in Selenium?

Use:
driver.manage().window().maximize();

32. What is WebDriverWait in Selenium?

WebDriverWait is an explicit wait that waits until a specific condition is met before continuing the script.

33. What is the use of driver.manage()?

It helps manage browser settings like timeouts, cookies, window size, and sessions.

34. How do you scroll a web page in Selenium?

Use JavaScriptExecutor.
Example:
((JavascriptExecutor)driver).executeScript(“window.scrollBy(0,500)”);

35. What is NoSuchElementException?

It occurs when Selenium cannot find the element using the given locator. It is common when pages load slowly or when locators are incorrect.

XPath & CSS Selector Interview Questions

Locators are one of the most critical areas in Selenium interviews. Most interviewers will test your understanding of XPath, CSS selectors, and how you find elements inside the DOM. If you explain locator strategies clearly, your confidence automatically increases.

Let’s look at the most frequently asked questions related to XPath and CSS.

36. What is XPath in Selenium?

XPath is a query language used to locate elements in an HTML document. It can search elements using attributes, text, hierarchy, and advanced patterns.

37. What is the difference between Absolute XPath and Relative XPath?

Absolute XPath starts from the root node (/html/body/…) and breaks easily. Relative XPath starts with // and can be used anywhere on the page, making it more stable for automation.

38. What is Dynamic XPath?

Dynamic XPath helps locate elements whose attributes keep changing. It uses functions such as contains(), starts-with(), and text() to identify elements reliably.

39. What is a CSS Selector in Selenium?

CSS Selectors are a fast and powerful way to find elements based on class, ID, attribute values, and hierarchical patterns.

40. Which is faster: XPath or CSS Selector?

CSS Selectors are generally faster because browsers optimise CSS rendering. XPath is more flexible but slightly slower in some cases.

41. What is the difference between XPath and CSS Selector?

XPath allows backward traversal and complex logic. Whereas CSS is cleaner, faster, and works only forward. Moreover, XPath is better for complex UI, and CSS for speed and simplicity.

42.How do you find elements using CSS Selector by ID?

Use the # symbol.
Example: #username

43.How do you find elements using CSS Selector by Class?

Use the . symbol.
Example: .btn-primary

44.How do you find elements using CSS Selector by Attribute?

Use square brackets.
Example: input[type=’email’]

45.How do you write XPath using contains()?

//input[contains(@name, ‘user’)]
Useful when part of the attribute changes.

46.How do you write XPath using text()?

//button[text()=’Login’]
Used when the visible text is constant.

47.How do you write XPath using starts-with()?

//a[starts-with(@href, ‘/login’)]
Works for dynamic links and buttons.

48.How do you find parent or child elements using XPath?

Parent: //div[@id=’box’]/parent::section
Child: //ul[@id=’menu’]/child::li

49. What is the difference between // and / in XPath?

/ searches from the root node.
// searches anywhere in the DOM.
Thus, // is more flexible.

50. How do you select the nth element using XPath?

(//input[@type=’text’])[3]
This selects the third matching element.

51. How do you select multiple conditions in XPath?

Use and/or.
Example:
//input[@type=’text’ and @name=’email’]

52. What is following-sibling in XPath?

It locates the next sibling of an element.
Example:
//label[text()=’Email’]/following-sibling::input

53. What is preceding-sibling in XPath?

It locates the previous sibling of an element.
Example:
//input[@id=’email’]/preceding-sibling::label

54. How do you handle SVG elements using XPath?

Use local-name():
//*[local-name()=’svg’]

55. What is the best locator to use in Selenium?

Always prefer ID (if unique).
If not available, use CSS Selector.
Use XPath for complex or dynamic elements.

Selenium Framework Interview Questions

Framework questions help interviewers understand if you can work on real automation projects. Knowing WebDriver is not enough companies need testers who understand TestNG, POM, Maven, data-driven testing, and overall framework architecture.

These questions will help you confidently explain how frameworks work and how they are designed in professional automation teams.

56. What is a Selenium Framework?

A Selenium framework is a structured way to organize test scripts, test data, reports, and reusable methods. It makes automation cleaner, faster, and easier to maintain.

57. Why do we use TestNG in Selenium?

TestNG helps organize and execute test cases, handle annotations, create test suites, manage data providers, and generate detailed reports. It brings structure into automation.

58. What are TestNG annotations?

They are special keywords, such as @Test, @BeforeMethod, @AfterMethod, @BeforeClass, and @AfterClass, that control the execution flow of test cases.

59. What is the use of the testng.xml file?

The testing.xml file allows you to run multiple test classes, groups, and suites together. It also helps in parallel execution and setting execution order.

60. What is Page Object Model (POM)?

POM is a design pattern that separates test logic from page elements. Each page has a separate class. This improves readability, reduces duplicate code, and simplifies maintenance.

61. What are the advantages of POM?

POM makes your tests reusable, reduces code duplication, supports easy updates when UI changes, improves readability, and helps build scalable frameworks.

62. What is a Hybrid Framework in Selenium?

A hybrid framework combines multiple approaches, such as POM, Data-Driven Testing, Keyword-Driven design, and TestNG. It is the most commonly used framework in real projects.

63. What is Data-Driven Testing?

Data-driven testing allows running a single test with multiple data sets using files such as Excel, CSV, JSON, or a DataProvider in TestNG. It increases test coverage.

64. How do you send test data using TestNG DataProvider?

Use @DataProvider to supply test data and map it using the @Test annotation. This helps run the same test multiple times with different inputs.

65. What is Maven, and why do we use it in Selenium?

Maven helps manage project dependencies automatically. It also provides a standard folder structure, making it easy to build, run, and update automation projects.

66. What is pom.xml in Maven?

pom.xml is the main configuration file in Maven. It contains dependencies, plugins, build information, and project details needed for Selenium automation.

67. What is the use of the target folder in Maven?

The target folder stores build outputs, such as compiled classes, reports, and logs generated by running the automation tests.

68. What are reusable components in a framework?

Reusable components include helper methods such as click-and-wait functions, browser setup, screenshot methods, and element wrappers that can be used across test scripts.

69. What is a Utility Class in Selenium?

A Utility Class stores standard reusable functions such as Excel reading, wait handling, screenshot capturing, and logging. It helps reduce code repetition.

70. What is the difference between POM and Page Factory?

POM defines the structure of page classes. Page Factory extends POM by using @FindBy annotations and lazy loading through initElements().

71. What is Framework Maintenance?

It means updating locators, improving reusable methods, modifying test data, cleaning unwanted code, and ensuring the framework works smoothly even when application UI changes.

72. What are Logs and Reporting in Selenium?

Logs help track issues. Reports show test execution results. Tools like TestNG reports, Extent Reports, and Allure are commonly used in automation frameworks.

73. How do you organize your folder structure in Selenium?

Common folders include:

pages
testcases
utilities
resources
