3. What is the difference between Selenium 3.0 and Selenium 2.0?
Selenium 2.0 is the merger of the original Selenium project and the WebDriver project. Although Selenium RC got deprecated, its use continued for backward compatibility.
Selenium 3.0 is an extension of Selenium 2.0 and does not include Selenium RC. However, it has increased stability, is inherently backward compatible, and has several bug fixes.
4. What are the testing types Selenium supports?
Selenium supports functional testing and regression testing.
Functional testing involves verifying each function of the application with the required specification.
Regression testing is a partial or complete selection of already executed test cases that undergo re-execution to ensure that existing functionalities are working as designed.
5. What is Selenese?
Selenese refers to the set of Selenium commands used to test web applications. These are of three types: action, accessors, and assertions.
Action commands interact directly with the application, accessors let users store values to a user-defined variable, and assertions verify the current state of the apps with an expected state.
6. What are the Exceptions in Selenium WebDriver?
Selenium WebDriver has Exceptions like any other programming language. Some of the most common Selenium WebDriver Exceptions are:
- NoSuchElementException: Thrown when an element in a given set of attributes isn’t present on the web page.
- TimeOutException: Thrown when a particular operation cannot be completed in a stipulated time.
- StaleElementException: This Exception is thrown when an element is deleted or no longer present in the DOM.
- ElementNotVisibleException: Thrown in cases when an element is present in the DOM but invisible on the web page.
7. Which API is used for database testing in Selenium WebDriver?
Java Database Connectivity (JDBC) API is used for database testing in Selenium WebDriver. JDBC allows users to write and execute SQL queries.
8. What are the types of waits supported by Selenium WebDriver?
Selenium WebDriver has three commands for implementing waits in tests. These are as follows:
Explicit wait: The explicit wait command tells the web driver to wait for specific conditions before throwing ElementNotVisibleException.
Implicit wait: It commands Selenium to wait for a definite amount of time before throwing NoSuchElementException.
Fluent wait: The fluent wait command is used to define the maximum time a web driver needs to wait for a condition and the frequency with which the user wants to check the condition before throwing ElementNotVisibleException.
9. What are the limitations of Selenium WebDriver?
Some of the limitations of Selenium WebDriver include:
- It cannot be used to test mobile and desktop applications
- Lack of built-in reporting
- Limited support for image testing
- Requires prior knowledge of programming language
- Lacks vendor support
10. How to launch different browsers in Selenium?
To launch a browser in Selenium, we need to create a driver instance for the browser we need to work upon. The WebDriver is the interface where Chrome, Firefox, and other browser driver implementations are made.
WebDriver driver = new ChromeDriver();
WebDriver driver = new FireFoxDriver();
11. What is a locator, and how do we locate an element in Selenium?
A locator is an address for identifying a web element within a webpage. In other words, it is a command that instructs Selenium IDE to operate on specific GUI elements. Locators are important because identifying GUI elements is necessary to create an automation script. Selenium uses different types of locators to identify web elements accurately. The locators are name locator, ID locator, CSS selector, XPath, partial link text, and link text.
12. How can we type text in an input box using Selenium?
The method sendKeys() is used to type text in input boxes.
Here’s an example:
WebElement email = driver.findElement(By.id(“email”)); – It uses the ID locator to find the text “email”
email.sendKeys(“abc.123@gmail.com”); – It enters text into the URL field
WebElement password = driver.findElement(By.id(“Password”)); – It uses the ID locator to find the text “password”
password.sendKeys(“xyz456”); – It enters text into the password field
13 What is driver.quit() and driver.close()?
Calling quit() on the driver instance when one or more browser windows are open closes all the open browser windows.
On the other hand, driver.close() closes the browser’s current window even if multiple windows are open.
14. What are the different browser navigation commands for Selenium WebDriver?
Some of the commonly used Selenium WebDriver browser navigation commands are:
driver.navigate().refresh(); – Refreshes the current page
driver.navigate().to(“https://www.upgrad.com/”); – Navigates to the URL provided
driver.navigate().back(); – Has the same job as clicking on the browser’s back button.
driver.navigate().forward(); – Has the same job as clicking on the browser’s forward button.
15. Can Selenium handle Windows-based pop-ups?
Since Selenium is designed to handle web apps, it does not have native support for Windows-based features. But integrating third-party tools like Robot and AutoIT can overcome this limitation.
With that, we come to the end of our Selenium interview questions.

Frequently Asked Questions (FAQs)
1. Is Selenium a programming language?
No, Selenium is not a programming language. It is a powerful open-source suite of tools designed to automate web browsers for testing purposes. However, Selenium provides language bindings, which are libraries that allow you to write your test scripts in popular programming languages like Java, Python, C#, JavaScript, and Ruby. While it does have a test-specific language called "Selenese" for use with Selenium IDE, its main power comes from its integration with these major programming languages.
2. What are the different components of the Selenium Suite?
The Selenium suite is composed of four main components. Selenium IDE (Integrated Development Environment) is a browser extension for quick record-and-playback testing. Selenium WebDriver is the core component, providing a programming interface to create and execute test cases by directly communicating with the browser. Selenium Grid is used to run tests in parallel on multiple machines and browsers simultaneously to speed up test execution. Finally, Selenium Standalone Server is used when you need to run tests on a remote machine.
3. What is Selenium WebDriver, and why is it so important?
Selenium WebDriver is the most crucial component of the Selenium suite. It is an object-oriented API that allows you to control a web browser programmatically. Unlike older tools, WebDriver interacts directly with the browser's native support for automation, making the tests more stable and realistic. This is a key topic in selenium interview questions because it is the primary tool used by automation engineers to write powerful, scalable, and robust test scripts.
4. What are the different types of locators in Selenium?
Locators are the mechanisms by which Selenium WebDriver identifies and finds web elements on a page. There are several types of locators, each with its own use case. The most common ones include locating elements by ID (most reliable), Name, Class Name, Tag Name, Link Text, and Partial Link Text. For more complex scenarios, you can use CSS Selector (which is very powerful and fast) or XPath (which is the most flexible but can be slower). Choosing the right locator is a key skill.
5. What is the difference between XPath and CSS Selector?
Both are powerful locators, but they have key differences. CSS Selector is generally faster and has a more readable syntax, making it a preferred choice for modern web applications. XPath is more powerful and flexible, as it can traverse both forwards and backwards through the HTML DOM, which CSS cannot. For example, XPath can find a parent element from a child element. This is a classic question in selenium interview questions and answers.
6. Can you use Selenium without coding?
Yes, you can. Selenium IDE is a no-code automation tool, available as a browser extension for Chrome and Firefox, that allows users to record their interactions with a website and then play them back as an automated test. It is excellent for beginners, manual testers, or for creating quick, simple test cases. However, for building complex and maintainable automation frameworks, using Selenium WebDriver with a programming language is the industry standard.
7. What are waits in Selenium, and why are they necessary?
Waits are essential for handling synchronization issues in web automation. Modern web applications are dynamic, and elements often take a moment to load. A wait tells WebDriver to pause execution for a certain amount of time before throwing an exception if an element is not yet present or interactive. There are three types: Implicit Wait (a global setting for the driver session), Explicit Wait (waiting for a specific condition to be met), and Fluent Wait (an explicit wait with more configuration options).
8. What is the difference between an implicit wait and an explicit wait?
An implicit wait tells the WebDriver to poll the DOM for a certain amount of time when trying to find an element if it's not immediately available. It is set once and applies to all findElement calls for the entire session. An explicit wait is more specific and flexible. It is applied to a particular element and waits for a specific condition to be met (e.g., waiting for an element to be clickable or visible) before proceeding. Explicit waits are the recommended approach for building reliable tests.
9. How do you handle alerts or pop-ups in Selenium?
Selenium WebDriver provides the Alert interface to handle JavaScript alerts, prompts, and confirmation dialogs. To manage an alert, you first need to switch the driver's focus to the alert box using driver.switchTo().alert(). Once you have the alert object, you can perform actions like accepting it (.accept()), dismissing it (.dismiss()), getting its text (.getText()), or sending text to it if it's a prompt (.sendKeys()).
10. How do you handle dropdowns in Selenium?
For dropdowns created with the standard HTML <select> tag, Selenium provides a convenient Select class. You can interact with the dropdown by selecting options in three ways: by their visible text (selectByVisibleText()), by their value attribute (selectByValue()), or by their index (selectByIndex()). For modern, custom-built dropdowns (made with <div>s or <ul>s), you would need to handle them by clicking the dropdown element and then clicking the desired option element.
11. What is the Page Object Model (POM), and why is it used?
The Page Object Model (POM) is a popular design pattern used in test automation to create a more maintainable and reusable test framework. In POM, you create a separate Java or Python class for each page of your web application. This class contains all the web elements (locators) and the methods that interact with those elements for that specific page. Your test scripts then use these page object methods instead of interacting with the WebDriver directly, which separates the test logic from the page implementation.
12. What are the advantages of using the Page Object Model (POM)?
The main advantage of POM is that it makes your test automation framework highly maintainable. If the UI of a page changes, you only need to update the locators in one place—the corresponding page object class—instead of in every single test script that uses that page. This reduces code duplication and makes the tests much easier to read and manage. This is a very important topic in advanced selenium interview questions.
13. How do you take a screenshot in Selenium WebDriver?
Selenium WebDriver provides a built-in capability to capture a screenshot of the current browser viewport. This is extremely useful for debugging test failures or for providing visual evidence in your test reports. The process involves using the getScreenshotAs() method on the WebDriver instance. This method can save the screenshot as a file, which you can then store in your project's directory.
14. How can you run tests in parallel using Selenium?
Selenium Grid is the component of the Selenium suite designed specifically for running tests in parallel across multiple machines, operating systems, and browser combinations. You set up a central "hub" and then register multiple "nodes" (which can be different machines or virtual machines) to it. When you run your tests, you configure them to point to the hub, and the Grid will distribute the test execution across the available nodes, significantly reducing the total time it takes to run your entire test suite.
15. What is the difference between driver.get() and driver.navigate().to()?
Both methods are used to navigate to a URL, and functionally, they do the same thing. However, the Maps() interface provides additional methods for browser history navigation. After using driver.navigate().to(), you can also use driver.navigate().back(), driver.navigate().forward(), and driver.navigate().refresh(). The driver.get() method is a more direct and commonly used synonym for Maps().to().
16. Can Selenium automate desktop applications?
No, Selenium is designed exclusively for automating web browsers and cannot automate native desktop applications. However, other tools can be integrated with Selenium to achieve this. For example, WinAppDriver (Windows Application Driver) from Microsoft can be used to automate Windows desktop applications, and it uses the same WebDriver protocol, so the syntax is very similar.
17. How do you handle multiple windows or tabs in Selenium?
Selenium WebDriver can manage multiple windows or tabs by using window handles. When a new window is opened, you can get a set of all current window handles using driver.getWindowHandles(). You can then iterate through this set and use the driver.switchTo().window(handle) method to switch the driver's focus to the desired window to perform actions on it.
18. How can I learn Selenium effectively?
The most effective way to learn is through a combination of structured learning and extensive hands-on practice. Start with a comprehensive program, like the software testing courses offered by upGrad, which can provide a strong foundation and expert guidance on building automation frameworks. It is also crucial to work on your own projects, such as automating a real e-commerce website, to truly solidify your skills and prepare for real-world selenium interview questions and answers.
19. What are some common challenges you face in Selenium automation?
Common challenges include handling dynamic elements that change their attributes, managing synchronization issues with slow-loading pages (which requires the proper use of waits), dealing with complex UI elements like captchas (which are designed to be anti-automation), and creating a stable and maintainable framework that can adapt to frequent application changes.
20. Does Selenium offer a promising career?
Yes, Selenium offers an incredibly promising career path. As almost every business now has a web presence, the need for high-quality, automated web testing is critical. Selenium is the undisputed industry standard for web automation. Therefore, the demand for skilled Selenium automation testers is extremely high and is expected to continue to grow, making it an excellent and stable career choice. Preparing for selenium interview questions is a direct investment in your professional future.
