Selenium Interview Questions for candidates with no experience/ fresher:
In short, the below set of questions is meant for freshers seeking to crack a selenium interview. These selenium interview questions are just basic/ level 1 questions that are generally asked for freshers. Nevertheless, with a small piece of advice let’s dive into the interview questions “Understand the concept, not byheart the answers”.
1. What is Selenium?
A. To summarize, Selenium is an automation testing tool used to test web applications on various web browsers. Nevertheless, it cannot be used for testing mobile and desktop applications.
2. Distinguish between manual testing and automation testing.
A. Firstly, manual testing is a process in which the tester manually inserts the credentials or inputs to check the application. On the other hand, in automation testing, a code is written to run the same test automatically using various automation tools like Selenium, UiPath, blue prism etc. This is the most common question often asked in selenium interview questions.
3. What is SDLC?
A. In general, SDLC is an acronym for software development life cycle and is a very crucial part of the pre-production testing of products. There are two types of testing as follows done before the product reaches its final stages. That is,
Manual testing.
Automation testing
4. Mention the various components of the selenium suite.
A. In short, the Selenium suite comes with four different components as follows:
Selenium Integrated Development Environment (IDE).
Remote Control (RC)
Web Driver
Selenium Grid
5. Can you explain the Selenium web driver?
A. Generally, the Selenium web driver is an interface that allows the tester to create and execute various test cases. Moreover, unlike the selenium remote control, it does not need any ideal server. This is an important question that is asked in majority of selenium interview questions.
6. Can you brief me about the selenium remote control?
A. In short, Selenium RC is a server that allows the tester to create and execute test cases in any programming language. However, those codes are converted into selenium core javascript before being sent to the browser.
7. What are the selenium parameter commands at a minimum?
A. There are four parameters in selenium.
Host
Port number
Browser
URL
8. Why selenium?
A. Firstly, it is an open-source tool. Further, it is compatible with multiple browsers and also supports various programming languages. Moreover, it also supports distributed testing.
9. Mention the verification points in Selenium.
A. There are two verification points in selenium
Selenium IDE
Web Driver
The former consists of both verification and assertion commands. Whereas, the Selenium Web driver depends on the coding and does not have any inherent verification.
10. Can you distinguish between assert and verify statements of selenium?
A. Firstly, this is one of the important Selenium interview questions.
Assert: using an assert statement, the tester can check/confirm the presence of an element on the page. Once the assertion is done, the workflow comes to a halt.
Verify: using a verify statement, the tester can check whether the condition provided is true or not. In this case, the workflow does not halt.
11. What are the differences between the commands driver.close( ) and driver.quit( )?
A. In short, Driver.close( ) is a command to close individual browser windows. Whereas, driver.quit ( ) is a command that closes all the windows open in the browser.
12. What are findElement( ) and findElements( ) commands?
A. In brief, as the term indicates, the findElement() command finds the first element on the page and returns a single web element. On the other hand, findElements() commands find and list all the web elements present on the current page.
13. Mention the different types of waits in selenium implicit.
A. To summarize, selenium consists of three types of waits: explicit wait, implicit wait, and fluent wait. Explicit wait waits for a specific condition before proceeding, implicit wait sets a default waiting time for elements, and fluent wait waits for a certain condition with a defined polling frequency. Another one of the widely asked selenium interview questions.
14. What are the various forms of frameworks available in Selenium?
A. To begin with, Selenium has five different types of frameworks as follows,
Data-driven framework
Key-word driven framework
Module-based testing framework
Behaviour-driven testing framework
Hybrid testing framework
15. Define same-origin policy and suggest a way to avoid it.
A. According to this policy, a tester cannot access coding scripts from other websites. However, this can be overcome through the proxy injection method. Besides, the Selenium server is used as a proxy to trick the browser into running the script from other sites.
16. What is an object repository?
A. In short, an object repository is a collection of web elements used in an application undergoing testing and their location values. However, in selenium, these elements are stored in an Excel sheet and later included in testing whenever it is needed.
17. What is a data-driven framework?
A. Data-driven frameworks allow the tester to separate test data and test code so that the same code can be used to test various data.
18. What are selenium annotations?
A. Generally, Annotations used in selenium are synaptic metadata added to the Java source codes. These annotations are provided in the test scenarios before every method. In case, if the annotation is not available for any of the methods then that particular part will be ignored in the process of testing.
19. What is the advantage of a selenium web driver over a selenium server?
A. In a word, the Selenium server plays the role of a mediator between the browser and the application. Whereas, selenium web drivers can instantly communicate with the browser to automate the process.
Selenium Interview Questions for experienced candidates:
Now that we are done with Level 1 questions, let’s start with the Level 2 selenium interview questions meant for candidates with previous work experience.
21. Why use Selenium RC?
A. Firstly, The Selenium IDE has certain limitations that can be addressed by using Selenium RC. It also offers better support for browsers and languages, thereby making the testing process more efficient and effective. Although the IDE is user-friendly, it lacks features like logging, iterations, conditional Statements, and test case result reporting, which can hinder its performance. Therefore, Selenium RC is often utilized to communicate with other languages such as Perl and Python, expanding its capabilities significantly. This is one of the most important selenium interview questions.
22. How do you handle dynamic elements in Selenium?
A. To handle dynamic elements, we can use techniques like using relative XPath, CSS selectors, or dynamic wait conditions such as explicit or implicit waits.
23. How do you handle pop-up windows in Selenium?
A. Firstly, Pop-up windows in selenium can be handled using the getWindowHandles() method to get the window handles. Besides, to switch to the desired window use the switchTo() method, perform operations, and switch back to the main window if needed.
24. How can you handle frames in Selenium?
A. In general, Frames can be handled using the switchTo().frame() method, where you pass the frame element or frame name/ID as a parameter to switch to that particular frame.
25. Explain the concept of Page Object Model (POM) in Selenium.
A. To summarize, Page Object Model is a design pattern that helps in maintaining test scripts by separating them from the web pages. Further, Each web page is represented as a class, and the elements and actions on that page are defined within that class.
26. What are the advantages of using POM in Selenium?
A. The advantages of using POM in Selenium are:
Firstly, the reusability of code
Also, its Improved code maintainability
Further, its Easy test script maintenance, and
Lastly, its Increased test script readability.
Do not miss as it is one of the major selenium interview questions.
27. How do you handle multiple windows in Selenium?
A. A tester can easily handle multiple windows in Selenium using the getWindowHandles() method to get all the window handles, also iterate through them and switch to the desired window using the switchTo().window() method, perform operations, and switch back to the main window if needed.
28. How do you perform mouse hover actions in Selenium?
A. In short, Mouse hover actions can be performed using the Actions class in Selenium. We can use the moveToElement() method to move the mouse cursor to a specific element and then perform actions like clicking, double-clicking, or performing other operations.
29. How can you handle dropdowns in Selenium?
A. One can easily handle Dropdowns, particularly using the “Select Class” in Selenium. Also, we can use the selectByVisibleText(), selectByValue(), or selectByIndex() methods to select an option from the dropdown based on its text, value, or index.
30. What is the use of TestNG in Selenium?
A. TestNG is a testing framework that is widely used in Selenium for test automation. Furthermore, It provides features like parallel test execution, test dependency management, test configuration through annotations, and generates detailed test reports. None of the selenium interview questions ends without this question!!!
30. How do you handle alerts in Selenium?
A. In a word, Alerts can be handled using the Alert interface in Selenium. That is, We can use the switchTo().alert() method to switch the driver’s focus to the alert, accept or dismiss the alert using the accept() or dismiss() methods, and retrieve the text of the alert using the getText() method. Make sure to touch this concept while preparing your selenium interview questions.
31. How do you handle SSL certificates in Selenium?
A. In general, SSL certificates can be handled by creating a custom class that implements the WebDriver interface and overrides the method to accept untrusted SSL certificates. Moreover, this class can be used to instantiate the browser driver and perform the test execution.
32. How do you handle file uploads in Selenium?
A. In a word, File uploads can be handled using the sendKeys() method on the file input element. You can also provide the file path as the argument to the sendKeys() method to upload the file.
33. Mention the various kinds of locators in Selenium.
A. In general, Selenium supports various locators like ID, name, class name, tag name, link text, partial link text, XPath, and CSS selectors to locate elements on a web page.
34. How do you capture screenshots in Selenium?
A. Screenshots can be captured in Selenium using the TakesScreenshot interface. Further, We can also cast the WebDriver instance to TakesScreenshot and use the getScreenshotAs() method to capture the screenshot as a file or as a base64 encoded string.
35. How can you handle cookies in Selenium?
A. In particular, Cookies can be handled using the WebDriver.Options interface. We can also use methods like addCookie(), deleteCookie(), deleteAllCookies(), and getCookieNamed() to manage cookies in Selenium.
36. How do you generate test reports in Selenium?
A. Firstly, TestNG provides built-in support for generating test reports. Further, using the TestNG framework, test results can be generated in formats like HTML, XML, or custom formats using listeners or reporters.
