This blog will guide you to answer the most important questions of the Selenium interview. you to answer the most important Selenium interviews questions. This blog will aid you in your preparation for your interview and help you make it easy. Before we go into the fundamental questions to ask, let’s look at the significance of the first question.
1. What is Automation Testing?
The use of automated tools to write and run test cases without manual involvement in the execution of an automated test suite is called automation testing. Automation tools are favored by Testers to create test cases or test scripts then organize them to form Test Suites. These tools are specifically designed to perform manually-designed test cases with no human involvement.
2. What are the benefits and advantages of automation testing?
The advantages of Automation Testing include:
(a) Save Money and Time.
Automation Testing improves accuracy because there is no risk of human error and user actions.
- Code reusability: Build once and run multiple times, with little or no maintenance and code reusability.
- Easy reporting: Test Browser automatically generates reports after completion of instances.
- Easy for compatibility testing by enabling synchronous execution when combined with OS and browser.
- Code duplication has made testing easier.
(b) More Reliable, Powerful and Versatile.
Automation Tools allow us to integrate with, Jenkins, GitLab, GitHub, Bitbukey, etc.
- Most commonly used for regression testing.
- It helps to monitor.
- Increases test coverage and test cases accordingly.
3. Number of test case cases did you have automated each day?
This is among the difficult Selenium interview question. The test scenario is based on the length and complexity. If the test case is simply the possibility of automating two to five test cases, and fewer or no test cases in the case of high complexity in the course of a single day.
4. What is Selenium?
Selenium is among the most well-known automated testing Suite. It is a playback tool that allows you to test functionally without understanding a scripting language. Selenium is an open-source, web-based UI-based automation suite. Jason Huggins developed this tool in 2004 when he was at ThoughtWorks.
5. What are the various Selenium suite components?
Selenium isn’t one tool or utility, but it’s a collection of different testing tools. That’s why it’s referred to as Selenium Suite. Each tool can be used in different tests and environments.
It has four parts, namely,
(a). Selenium Integrated Development Environment (IDE):
It is available as a Firefox plugin that functions as a recording and playback tool. It was created to speed up the development of automated scripts.
(b). Selenium Remote Control (RC):
Selenium Remote Control is a server that allows the user can write Test cases using any desired programming language. The action commands contained in test scripts are recognized by the server and then sent to browsers in the form of Selenium-based Javascript commands, which will maintain the browser’s behavior in accordance with the commands.
(c). Selenium Web driver:
Selenium Web Driver can be described as a programmatic interface that allows you to build and run tests. It lets you perform actions on web elements. The Web driver doesn’t require an additional server, as opposed to Selenium Remote Control.
(d). Selenium Grid:
The Selenium Grid can be used to distribute commands to various machines at the same time. It facilitates the simultaneous execution of tests in various browsers and various environments. It ensures integrity and concurrency within testing with Test Suite Execution.
6. What are the benefits of using Selenium?
- Open-source
- The community has a huge amount of support and users is huge.
- Cross-browser compatibility (Firefox, Chrome, Edge etc.,)
- Multiple programming language support (Python,Java, Perl etc.,)
- Daily or routine development of the repository
- Distributed testing is possible.
7. What is the most significant differences that separates Selenium 3.0 as well as Selenium 2.0?
Selenium 2.0 is the result of the merger with The Original Selenium project and Web Driver. Web Driver Project. Selenium RC was the original project. Selenium RC got deprecated but was still used to support backward compatibility.
Selenium 3.0 often called an extension of Selenium 2.0 is inherently backward stable and has numerous bug fixes. It is not a part of Selenium RC. Selenium RC at all.
8. What is Selenese?
Selenese which is also known as”the Selenium command, is actually the list of selenium commands used to run your tests. For instance”open” (URL) is an example of a Selenium command that allows you to open the URL you specify in the particular browser. Test scripts are the combination of these commands that are grouped together. There are three kinds of Selenese. They are:
- Actions: We could use it to perform operations and interactions on the element in selenium that we are targeting
- Accessors: They are used to store the values of the variables.
- Assertions: They can be used as checkpoints in order to keep an eye on the flow of commands.
9. What are the parameters that commands involving selenium include at a minimum?
Four conditions must be satisfied for you to be able to pass Selenium. These are given below.
- Host
It is possible to connect to the Selenium with an address specifically for it, instead of an internal host within your local system.
- Port Number
You can select which port to connect, as well i.e. TCP/IP port which connects this Selenium tests directly with Grid hub. Grid hub. It is imperative to make sure that there’s not another application with identical port numbers in a different place on this machine.
- Browser
The browser in which selenium scripts are run.
- URL
The URL for the application will trigger tests included within it.
10. How can you distinguish between absolute Path and Relative Path?
Absolute Path:
- The path begins with the root node and ends with the element’s desired node.
- It starts with a single (“/”) followed by an Slash (“/)
- Example: /html.body/div/td/input
Relative Path:
- This path starts at any node that is between them and leads to the element that you want.
- It starts with an apostrophe, followed by a the double Slash (//)
- Example: //input/example[@id=name]
11. What’s the difference between Assert and verify assertions using Selenium?
Assert:
- You can check whether an element appears on the page or not.
- Test fails and ends at the time of failure in the tests. The program controls ceases.
Verify:
- It’s all about declaring whether the condition stated is valid and/or not.
- The control flow of the program does not stop due to this.
It is evident that using the Verify statement is not able to stop the program’s execution however the Assert statement will stop the execution.
12. What is the major difference between FindElement() and FindElements ()?
findElement() :
It employs the method of locating specified to find the initial component on the webpage and return one element from the web page.
findElements():
It also makes use of the mechanism of finding to find every element on the current page, and provides an exhaustive list of elements on the web.
13. What are the types of verifications which are provided by Selenium?
- Selenium IDE Verify and then apply commands
- Selenium web Driver It doesn’t provide built-in features that aid in verification, and depends on the style of code that we decide to employ. A few examples are looking at the page’s title or specific text that appear on the site, and looking for specific elements such as dropdowns, textbox fields textbox, and so on.,
14. What is the difference between Implicit Wait, as well as Fluent Wait?
(a). Implicit Wait:
You can specify the timeout period for an exact period of time for each of the web elements that are in succession.
(b). Fluent Wait:
It’s a slight increase to the wait that is explicit. we can set the frequency with which we check the condition before throwing the ElementNotVisibleException.
15. What is the primary difference in driver.close() driver.quitstrong> as well as driver.quit ()?
driver.close():
It’s a command which allows the window that is currently open to close. For instance, when we have several browsers open, by using this option, we could close the browser in the one we’re currently in.
driver.quit():
The command closes any browser window that is at present open. If, for instance, you have several browser windows open, this command will close all the windows at once.
16. Can Selenium manage windows-based pop-ups?
We know that Selenium can be described as an automation tool to test which works only with websites-operating applications. So, pop-ups in windows are not managed through Selenium. However, by integrating tools provided by third parties it is possible to resolve this problem.
17. What exactly is the meaning of an Object Repository and how to make an Object Repository with Selenium
18. What are the different types of frameworks?
Data-driven framework:
This test information is generated by using other external files, such as spreadsheets, CSV, XML documents, and so on. The information about the tests is dependent on the input data and verification information stored inside the variables.
Keyword-driven framework:
The tables of data and the keywords are designed independently of the automated tests. The operation of the test scenarios is described in the table, step-by-step section.
Test framework based upon module:
Logical and isolated modules are created from the test application. Independent test scripts are written in each module. The scripts are then put together to create a complete.
Framework to test based on behavior:
Test scripts have been written to ensure that automated testing is carried out on features or functions to guarantee access, comprehension, and credibility for professionals in the field of business, developers or others who test.
Framework for testing that’s a hybrid testing framework
Combining more than one of the frameworks mentioned that combine the strengths of each is referred to as the Hybrid testing framework.
19. What is the policy on same-origin? How can we prevent it?
This policy was formulated to ensure security.
- This policy guarantees that we can’t access the script via a different website.
- The source code loaded by the browser may only be used within the website’s domain.
- This can be circumvented with the use of proxy injection. This method is where it is tricked by the web browser into believing the server of Selenium to appear to make it appear as a real URL (fictional URL).
20. What is the difference between obtainwindowhandle() and the obtainwindowhandles ()?
getwindowhandles() getwindowhandles(): This function is used to determine addresses of each open browser, and return the type of data of Set.
getwindowhandle() getwindowhandle(): This method is used to determine information about the location of the browser window it’s located on, and return the type of data String.
21. What are the various types of Annotations that are used in Selenium?
Syntactic metadata is a feature that can be included in Java source code. This is referred to as annotations. These can appear in packages, variables, parameterization classes, variables, and more. Some of them that are utilized to create Selenium include,
@Before, @Test, @After
22. What is the main difference in the setsSpeed() as well as sleep() methods?
This will slow down the time of execution.
Thread.sleep(): The thread in question will shut down for a predetermined amount of time. It will wait until the command is issued. It only requires a single argument in integer format.
setting sleep(): This command stops the execution for each selenium-related command. This command is only used for demonstration purposes, and for slow web applications.
23. What are the benefits that come with Web driver to Selenium server?
- When Selenium Web Driver is being used there is no need to depend on the Selenium server.
- Selenium server gives us the capabilities of Selenium RC to ensure backward compatibility.
- Selenium server is a middleware to facilitate communication between browsers in selenium as well as the application. While Selenium web driver Selenium web driver calls the browser environment, enabling it to automate.
24. How do you save an amount of data in the form of a text box?
A command that can save values from the text box by using web drivers.
For instance,
driver.findElement(By.id(“your Textbox”)).sendKeys(“your keyword”);
25. What can you do to debug the tests that are in Selenium? Selenium IDE?
- It is necessary to first add breakpoints in order to investigate and then run the test step-by-step.
- Then, run your test.
- The execution ends at the point at which the breakpoint is maintained.
- You can hit the Run button to resume the execution of the commands in succession.
26. Are regular expressions?? What can you do with regular expressions to enhance your studies in Selenium?
There are Search patterns can be represented by the unique Text string that is known as the regular expressions. Regexp is the word that is utilized as a prefix for treating the text in Selenium as regular expression.
27. How do you work using multiple screens in Selenium?
SelectWindow() command within Selenium is a command that can switch between the windows that are currently active. The most distinctive feature among windows is the name for the particular window.
28. How can the message contained in the box alert be read?
storeAlert() command is used to get the message that was displayed in the alert pop-up and save it in an undefined variable.
29. What can you do to verify the precise location of an online element?
verifyElementPositionLeft and verifyElementPositionTop commands are used. These commands make use of the pixels comparison to determine the location of the element from the left and the top of the web page, respectively.
30. Uses of Selenium RC?
- Selenium IDE has the limitations that Selenium RC can diminish in terms of browser support as well as language support.
- IDE is not able to provide many functions such as logging, iterations, tests, conditional statements report, and so on. It is only compatible with HTML Language.
- This is the reason why Selenium RC is used to communicate with other languages such as Perl, Python, etc.,
31. What are the benefits or benefits of Selenium RC?
The advantages or benefits that come from RC include,
- The data can read write to or .xlsx, .csv, .txt etc.
- Dynamic elements, as well as Ajax-related UI elements, are able to be handled.
- Iterations functions and Conditional Statements are a great way to improve and increase flexibility and performance.
- Support for all operating systems and programming interface languages.
- Selenium is a browser plugin that is compatible with any browser that is compatible by Javascript.
32. Do you have a list of the technical limitations when making use of Selenium RC? Selenium RC?
- Same-origin policy
- Anything that is not in the browser is also limited to the execution of the test scenario.
33. Why is it necessary to utilize the TestNG together with Selenium Why should you use RC?
If this automation suite is able to run against different client and server platforms, then we will need to invoke the test scenarios using commands. Additionally, we require reports on test results frequently to calculate estimates and to also allow the possibility of creating the tests. This kind of flexibility is offered by TestNG.
34. Which language do you utilize to build test case suites for Selenium?
The most popular method of implementing Selenium can be Python instead of Java. This is due to
- Java programs can be slower to run when compared to Python programs.
- The execution and the complexity are different, but Python is a great choice.
- Python can be dynamically typed, whereas Java can be statically typed commands.
- Java isn’t as simple or simple to write test cases in comparison to Python.
35. What are Start and Breakpoints? in Selenium?
- Breakpoints
The execution process is stopped by breaking points. This way we can determine if the code is running in the way we expect or not.
- Starting points
The location from which the execution will start is determined by starting point. If you are planning to run an experiment starting from the middle of the code, or breaking point, you can use these.
36. What makes the capability you want beneficial in the context of Selenium?
Key-value pairs are used to store details like the name of the popular browser and browser version and browser history as well as the path for the driver for the browser in the system as well as. This information is used to analyze how the web browser behaves during the time of its execution. This function or feature is generally called the desired capability.
For Selenium,
The driver instance is set up using this method.
It’s a good idea to do this when you need to test the cases across various Operating platforms, browsers and versions.
37. When do you use AutoIT?
We already have learned, Selenium is used to automate web-based apps. However, if we wish to maintain or maintain the GUI, HTML, pop-ups, then we require AutoIT. AutoIT.
38. Please explain why you need Session management in Selenium?
Session handling is crucial when working using Selenium. This is due to the fact that when working on test cases, we have to establish a connection between browsers and applications before performing the commands. There is a possibility when, while running a specific test script, a different test script could be executed on the same host, and the same kind of browser. It is a critical element and the reason we require session handling.
39. Are you able to automatize CAPTCHA?
The answer is no. We are unable to automatize CAPTCHA within Selenium. The purpose of CAPTCHA is to make sure that automated test scripts do not be able to access sensitive data which is the reason why we are unable to automatize the process. The captcha needs to be entered manually in order to keep the flow of testing.
40. How can we launch various browsers on Selenium?
- A driver instance needs to be developed for a specific browser we want to work on.
- WebDriver driver = new FireFoxDriver();
- WebDriver driver = new ChromeDriver();
- This is where the WebDriver is the user interface through which the Firefox chrome, Chrome, and another driver for browsers implementations are created.
41. What is Locator? And how can you find elements in Selenium?
The elements on the page are identified and linked using locators that interact with. There are different types of locators that can be used to locate different kinds of elements found that are on the website page. They can be described as follows:
- ID
- Name
- Class
- Partial Link
- XML Path
- CSS locator
- Link Text
42. Why should you select Selenium rather than QTP (Quick Test Professional)? )?

44. What are the testing types to be that are supported by Selenium?
Testing for Regression Testing as well as Functional Testing is assisted by Selenium.
- Regression Testing:
All Test scenarios are run repeatedly either in part or complete to make sure that the functions work as intended. This includes the following steps,
- Re-testing The test instances within the Test Suite are executed which is expensive and time-consuming.
- Regression Test Case Selection: The test cases are classified into categories such as integration tests, features tests, etc. Some test cases are chosen.
- Prioritization of Test Cases: Test cases that are chosen are prioritized according to the most critical functions and their business impact.
2. Functional Testing:
In this way, all functions of the application are checked against the specific requirements. This is mostly black-box testing since it’s not concerned with the codebase that the software. It comprises the following steps:
- Test input is recognized.
- Test Outcomes are calculated.
- This test is run
- The actual test result and the test results are compared with execution time in this manner.
45. What are the different kinds of exceptions within the Selenium Web driver?
The exceptions that are part of Selenium’s Selenium Web driver are similar to those in other programming languages such as Java, C#, and so on. The most frequently encountered exceptions are:
- TimeOutException This error can be caused when a specific procedure is not completed within the time specified or specified.
- NoSuchElementException: Thia exception is thrown when an element in the given set of attributes is not present on the web page
- ElementNotVisibleException: This error is thrown when a particular element can be visible only in the DOM (Document Object Model) but not visible on the web page.
- StaleElementException: This exception is thrown When an element is either deleted or no longer present in the DOM
46. What API is used to conduct testing databases in Selenium? Selenium Web driver?
JDBC (Java Connection to Databases) is used to perform testing databases in Selenium. This lets us write SQL (Structured SQL Query Language) queries and then execute the queries.
47. Do you have a code snippet that will launch the Chrome browser using Web Driver?
48. Are you able to discuss the difficulties you have to overcome when handling Ajax calls within the Selenium Web driver?
Here are some of the issues we face when dealing with AJAX calls.
- The command to pause in Ajax calls isn’t conventional and reliable for handling. The long pauses in a test case to execute more quickly, increase the amount of time it takes to execute. You can try using the waitForCondition instead of waiting for AJAX applications. AJAX applications.
- The risk assessment that comes with the use of these apps is a challenge.
- The encoding and serialization features of the AJAX applications make it challenging to design automated test cases.
49. Do you have a way to explain how you handle colors in the web driver?
It is possible to make use of this command getCssValue(arg0) to get the colors using the color in the argument.
50. Which web-based driver will be the most efficient?
The implementation of the web driver HTML Unit Driver can be described as the most efficient of all. This is due to the fact that it doesn’t run the tests inside the browser, but instead does only the basic HTTP which is faster than you would expect.

- regular updates Selenium Support is built on a community model system that permits frequent updates and upgrades. The upgrades are easy to install and do not require specific instruction. Selenium is, therefore, both productive and economical.
- Selenium suites that contain lots of information: Selenium is more than a utility or tool. It’s an entire set of testing tools, which is the reason it’s called a suite. Each tool is customized to the specific needs of testing and testing environment requirements. Selenium includes additional tools like Selenium IDE, Selenium Grid as well as Selenium Remote Control (RC).
- Its ease with the possibility of implementing it: Selenium has a user-friendly interface, which makes it easy to create and test. Its open-source capabilities permit users to create the extensions of their choice, which makes them easy to design, alter actions, and later at a higher level. Selenium’s reporting capabilities are one of the main reasons behind its popularity since it allows testers to collect results and take action based upon the results.
59. What are the negatives of using Selenium to test your software?
These are the drawbacks of using Selenium as a tool for testing:
- Tests web-based applications only Selenium is able to support the testing of web-based applications. Applications for mobile devices, Captcha, and Barcode readers are not tested with Selenium in the absence of integration with third-party tools such as Appium or TestNG.
- It does not have a built-in reporting feature or testing management feature: Selenium can generate reports only with third-party tools such as TestNG or JUnit.
- Inaccessibility of dependable technical support As Selenium is an open-source tool there is no specific support for user-related issues is provided.
- may require knowledge about programming language Certain prior programming experience is required to utilize Selenium.
60. What is the most suitable language to deal with selenium?
Python, as well as Ruby, are the most Selenium binding language because the software will auto-load the driver if located in the same directory as your system, or the Python path.
Others:
- Java: Java is still the most used programming language used for the automation of tests however it is not the best choice since it’s not a scripting language.
- JavaScript: JavaScript is utilized for automated testing by 35 percent of our users who write their tests in this language.
61. What is the reason Selenium should be chosen as a tool to test web-based applications or systems?
Selenium has the following benefits that make it an ideal automated testing framework
- It is free and open-source software with a massive number of users and a strong community.

The following commands are able to be used to open web browsers with Selenium:
WebDriver driver = new FirefoxDriver();WebDriver driver = new ChromeDriver();WebDriver driver = new InternetExplorerDriver();
63. What exactly is Selenese? Discuss the various types of Selenium commands.
The language used to write test selenium script within Selenium IDE is called Selenese. It is an assortment of commands to test your website applications or systems. Selenium commands are categorized into three major categories:
- actions: They are commands that directly interact with web-based applications.
- Accessors They are commands that let users store data in an individual-defined variable.
- assertions: It allows a comparison of the status of the application to the expected state.
64. What exactly is a locator? And, if you can, name the various types of locators that are found in Selenium.
A locator is a way that uniquely identifies web elements on a page. There are various kinds of locators that are available in Selenium to identify web pages specifically and precisely, for example:
- ID
- Select Class
- Name
- TagName
- LinkText
- PartialLinkText
- Xpath
- CSS locator
- DOM.
65. Explain the main distinction of “assert” and “verify” commands in Selenium.
“assert” and “verify” commands are identical “assert” and “verify” commands determine if the condition is true or not The only difference is the following:
- Assert This condition aborts the test in the event that the specified condition is not true, otherwise, it will continue to run the tests.
- Check: Verify the condition does not stop the flow of program execution, regardless of whether the condition is either true or false
