If you are looking for Selenium Interview Questions and Answers, in this article we are going to discuss the top 25 most asked Selenium Interview Questions and Answers. An interview can be stressful, especially if you haven’t had one in a while or don’t know what to expect.
You may feel unprepared and even less confident about your abilities, but it’s essential to go into an interview feeling prepared and confident. To help you get through this process, we’ve put together a list of Selenium interview questions that you may encounter during your following Interview so that you can be sure to answer them all correctly!
Selenium Interview Questions and Answers
Here are the top 25 most asked Selenium Interview Questions and Answers:
-
What is unit testing?
Unit testing is software testing that tests individual units of source code. A team is an independent, standalone section of code that performs one specific task and does not rely on other areas or modules. Unit testing can be contrasted with other black box or white box software testing, where larger code sections are tested.
-
Explain various test types in automation?
There are various test types in automation, each serving a different purpose. These test types are Unit Testing, Integration Testing, Smoke Testing, Regression Testing, Performance Testing, and Acceptance testing. Unit testing: Unit testing is done when we write a program to execute unit-level code.
-
What are the various levels of automation?
Selenium tests can be automated at multiple levels, including user interface (UI), integration, and system tests. The lower levels are slower to execute but produce more accurate results, while higher levels have less accurate results. A good balance is vital for optimal automation.
-
Can you explain various approaches for data-driven testing?
Data-driven testing means that tests are specified in terms of example data, which can be anything from a small set of sample records (e.g., a few rows from a typical database table) to large volumes of realistic or non-realistic test data.
Data-driven tests have many advantages over procedural (also called scripted) tests: they lead to higher code coverage, provide excellent documentation for non-programmers, and allow tests to be run automatically at any time.
-
How do you manage your time in the TDD approach?
It will help manage your time effectively since you are writing test cases after coding and running them. This can be done by having an excellent understanding of the Selenium framework and tools.
You need to know that executing test cases is not an easy task, but with Selenium, it has become possible. It is essential to understand how to get started with it and what languages can create test cases? In which language selenium IDE’s are available?
-
Mention a few challenges faced by the tester in automation.
As automation has become more popular, a few challenges need to be overcome to fully integrate automation into software development. One of these challenges is incorporating it with manual testing. Many companies are still having issues finding ways to efficiently run their manual and automated tests together.
-
What are the advantages of using Selenium as an automation tool?
Selenium is an automation tool that allows you to write test scripts in a programming language of your choice (Java, C#, etc.). Using Selenium as an automation tool has many advantages:
- It’s free and open-source.
- It allows for cross-browser testing, including mobile browsers.
- It gives you access to regular browser navigation and not just web element clicks.
- It allows for faster execution of tests than similar tools.
-
What are the disadvantages of using Selenium as a testing tool?
Although Selenium is a great way to simulate user interaction within your applications, it’s essential to know some disadvantages. Here are a few examples
-
Why should Selenium be selected as a testing tool for web applications or systems?
Selenium is open source and free to use, thus reducing the cost of testing. Selenium WebDriver provides easy language bindings in various programming languages like Java, Python, C#, etc. Selenium enables testers to test on real browsers across multiple operating systems.
Selenium has enormous community support that generates new test scripts and quickly fixes defects. Since it integrates with different IDEs such as Eclipse, IntelliJ IDEA, Visual Studio, etc., programmers find it easier to write code for automating tests using Selenium IDE (Selenese).
Selenium tests can be easily integrated with build tools like Apache Ant, Maven, etc. These tools allow the execution of test suites as part of the continuous integration cycle.
-
Can Selenium be used to launch web browsers?
No, Selenium cannot be used to launch web browsers. Selenium is a tool that can automate tests against web applications. It simulates user activity in a browser so that you can test your application and make sure it’s working correctly. Still, it doesn’t control any web browsers or their plugins.
-
What is meant by Selenese? Explain different types of Selenium commands.
Selenese is a domain-specific language for writing automated tests in Selenium. Different types of Selenium commands can be used for various purposes, such as finding an element on a page, validating user input, or asserting that an element’s value has changed.
The complete list of available commands depends on your specific implementation of Selenium. Still, all implementations provide a set of controls for finding elements on web pages and navigating between pages.
-
Explain the same-origin policy and how Selenium handles it?
The same-origin policy refers to a concept that helps ensure web browsers remain secure. All browsers keep lists of sites that are allowed to make cross-domain requests, and if a site or page doesn’t appear on one of these lists, users will receive an error when they try to interact with it.
Selenium has built-in features that allow you to create custom rules for specific pages, but these rules can be challenging to manage.
-
What is automation testing, and what are its advantages?
Automation testing is a type of software testing that involves using special software (called automation tools) to execute pre-scripted tests. Utilizing automation can save time and increase productivity by quickly performing large trials.
Furthermore, automation lets us test in ways that aren’t possible with manual techniques—for example; you could use Selenium IDE or Cucumber to record users as they go through your application and then re-run those recorded scripts for more thorough testing.
Conclusion: Selenium Interview Questions and Answers
It is essential to plan your Interview. When you don’t know what to expect or what questions they may ask, you will be on edge and nervous. Write down some notes on how you would answer those questions if your brain decides to go blank during an interview question.
Practice answering these sample interview questions out loud in front of a mirror so that you can get used to saying these answers confidently and quickly.
