Individuals can do web application testing with Selenium, an open-source, automated tool. Selenium has become a vital feature of some of the most popular browsers. Take advantage of the best online Selenium training in Singapore if you want to begin your career as a test automation engineer and improve your chances of getting a job in the field.
Check out a few challenging Selenium automation testing questions to help you prepare for your interview.
Basic interview questions
Q1. What does automation testing mean?
Ans: Automation testing or Test Automation is the practice of automating an application’s or system’s manual testing process through testing tools that enable the creation of scripts that can be run repeatedly, creating detailed test reports for the application or system under test.
Q2. What are the advantages of automation testing?
- You can save money and time.
- Automation Testing improves accuracy by eliminating the possibility of human error.
- Reusability of Code
- Easy reporting
- Compatibility testing is made more accessible by allowing simultaneous execution on multiple operating systems and browsers.
- Highly powerful, versatile, and reliable.
- To interface with Jenkins and GitHub, we use Automation Tools.
- Automation Tools are primarily used for Regression Testing.
- Monitoring test coverage and adding more tests as necessary are made more accessible with the aid of this feature.
Q3. What do you know about Selenium?
Ans: It is the topmost widely used automated testing tool. You can perform functional testing without any knowledge of test scripting languages with this playback tool. A web UI-based automation testing package, Selenium is free and open source. Jason Huggins created it at ThoughtWorks in 2004.
Q4. Tell me a few disadvantages of using Selenium as a testing tool?
- Cannot rely on technical help – Due to the nature of open-source software, technical support is difficult to come by.
- It is limited to Web-based apps.
- Because Selenium only provides a programming interface, it takes longer to construct test cases.
- Difficulty in setting up a test environment using technologies such as UFT, RFT, and SilkTest
- Support for Image Testing is limited.
- New features may not function correctly.
- There is no integration of a test tool for testing.
Q5. What does Selenium Suite mean?
Ans: It is commonly referred to as a Selenium Suite since it includes several different testing tools designed to meet a specific testing need.
Q6. What are the Selenium Suite’s different components?
Ans: Here is a list of the various Selenium Suite components:
Selenium IDE (Integrated Development Environment): You may use it to create automation scripts by capturing user activities on the browser and exporting them as a reusable script with this Firefox/Chrome plug-in.
- Selenium Remote Control (RC)
- Selenium WebDriver
- Selenium Grid
Advanced interview questions
Q1. What are the different sorts of waits that WebDriver supports?
Ans: WebDriver supports two distinct forms of waits:
The implicit wait is used to specify a default interval (say, 30 seconds) between consecutive test stages throughout the test script. Thus, the future test step would be conducted after the 30 seconds have passed since the previous test step was executed.
Explicit Wait: It is used to suspend execution until a specified condition is satisfied or the specified period has elapsed.
Q2. Describe the difference between driver.close() and driver.quit() command in Selenium?
Ans: The driver.close() command shuts down the user’s window, or the web driver is presently accessing. Unlike the driver.close(), driver.quit() should be used with caution because it closes all of the program’s windows.
Q3. What is the pause feature in Selenium IDE?
Ans: To enter into debug mode, a user can click on the pause symbol in the upper right of the IDE when an exception is thrown in a test script. As a result of this feature, the complete test case does not fail, and users can address the issue quickly.
Tricky interview questions
Q1. How to use Selenium WebDriver to handle an Authentication Pop-up?
Ans: Applications need to be more secure in light of the rapid evolution of IT. For this reason, many firms have their proxy settings for apps. Their server will prompt you for your login credentials if you open it in a browser. Before reaching the server, even Selenium has to deal with the same auth pop-up that the user does.
Q2. Is Selenium capable of testing responsive web design?
Ans: Because many people now use smartphones and tablets to access applications, responsive web design testing is critical. A time-consuming and labor-intensive task, manual software testing across all platforms could cause delays in releasing new versions. You can use a framework called Galen to automate RWD testing. You may use this Selenium Grid add-on to run several tests simultaneously and run the tests in the cloud.
Q3. What is the significance of assertions in Selenium?
Ans: Assertions are essential for validation, and a clear indication is given as to whether or not a test case behaves by expectations. Assertions assist testers in determining if a test case has passed or failed.
Fresher interview questions
Q1. Why would I need Selenium?
- Support from the community
- Massive user base
- Cross-browser compatibility is excellent (Firefox, Chrome, Edge)
- The ability to use more than one programming language (Python, Java, Perl)
- Developments in the repository on a daily or frequent basis
- There is also support for distributed testing
Q2. Is Selenium capable of handling pop-up windows?
Ans: Selenium is a web-application automation testing tool, as we already know. As a result, Selenium cannot be used to test the pop-up window in Windows. This problem can be solved, though, if we integrate with third-party technologies.
