Introduction to Selenium Interview Questions
The following article provides an outline for Selenium Interview Questions. Selenium is focused on automating web programs for the sake of research, but it is much more than that. The functions of web-based management can also be automated. It automates the use of browsers. Selenium supports the most popular browser vendors, embracing it and making it an integral part of their browser. Many other browser automation tools, APIs, and frameworks use this technology as well.
If you are looking for a job related to Selenium, you need to prepare for the 2021 Selenium Interview Questions. Every interview is indeed different as per the different job profiles. Here, we have prepared the important Selenium Interview Questions and Answers, which will help you succeed in your interview.
In this 2021 Selenium Interview Questions article, we shall present the 15 most important and frequently asked Selenium interview questions. These interview questions are divided into two parts are as follows:
Part 1 – Selenium Interview Questions (Basic)
This first part covers basic interview questions and answers:
Q1. What is software testing or test automation?
Software testing uses automation software to write and execute test cases; there is no need for human intervention when running an automated test suite. To write test scripts and test cases, testers tend to use automation software, which they then organize into test suites. The use of advanced software to automate the execution of manually constructed test cases without the need for human interaction is known as automation testing. Accessing test results, controlling test execution, and comparing the real outcome to the predicted result are all capabilities of automation testing software. As a result, detailed test reports of the system under test are generated.
Q2. What are the benefits of automation testing?
The following are some of the most basic advantages of automation testing.
- In an application, automation testing facilitates both technical and output tests.
- It allows us to run test cases over and over again.
- It makes parallel execution easier.
- It makes it easier to assess a large test matrix.
- It increases accuracy by eliminating the possibility of human error.
Q3. Tell some of the most widely used automation testing software for functional automation.
The below are the top ten most commonly used automation research methods for Functional Automation.
- Teleric Test Studio
- Selenium, open-source
- Tosca Testsuite
- HPE Unified Functional Testing
- Rational Robot, by IBM
- Quick Test Professional, by HP
- Coded UI, Microsoft
- Auto It, Open Source
Q4. Tell some of the most widely used automation testing software for non-functional automation.
The below are the top ten most commonly used automation research methods for Non-Functional Automation.
- Burp Suite, by PortSwigger
- Load Runner, by Hp
- JMeter, by Apache
Q5. What is selenium?
Selenium is a lightweight software testing platform. The Selenium tool comes with a replay tool that allows you to create functional testing without having to master a test scripting language. Selenium is a popular open-source Web UI (User Interface) automation testing framework. Selenium is an automation framework that works for various apps, browsers, platforms, and programming languages.
Q6. What are the different components of selenium?
Selenium is a single tool and a suite of software’s, each having a different approach to support automation testing.
It comprises of four major components, which include:
- Selenium IDE (Integrated Development Environment)
- Selenium Remote Control
- Selenium Grid
Q7. List all of the programming languages and operating systems, browsers and programming languages that are supported by selenium.
Selenium is compatible with a wide range of operating systems, browsers, and programming languages.
- Android, iOS, Windows, Linux, Mac, and Solaris are some of the operating systems available.
- Google Chrome, Mozilla Firefox, Internet Explorer, Edge, Opera, Safari, and others are examples of browsers.
Q8. In selenium, what are the various kinds of locators?
A locator is a type of address that provides a one-of-a-kind means of defining a web feature on a webpage.
To classify various elements of a website, Selenium has a number of locators, including:
- CSS Selector
Part 2 – Selenium Interview Questions (Advanced)
Let us now have a look at the advanced interview questions:
Q9. What is selenium assertion?
As a verification point, the assertion is used. It confirms that the application’s current state is as intended. “assert,” “verify,” and “waitFor” are the three forms of assertions.
Q10. Can you describe the difference between the selenium assert and verify commands?
Both the assert and verify commands are in charge of determining whether a condition is true or false. The biggest difference between the two is what each of them does after the condition testing is over. In the case of a verified instruction, if the condition is false, the execution will halt, and no further tests will be run. If the condition is true, however, the program control will proceed to the next test phase. The verify, on the other hand, is unconcerned about the condition testing output.
Q11. What are the various kinds of annotations that selenium uses?
The following JUnit annotations can be used:
Q12. What are the selenium WebDriver exceptions?
Selenium WebDriver has five distinct various exceptions.
Q13. What is Selenese?
The language used in Selenium IDE to write test scripts is called Selenese.
Q14. What’s the difference between keyboard shortcuts and keyboard commands?
Q15. What is selenium IDE, and how does it work?
Selenium IDE is a Firefox plugin that allows you to store and replay test scripts. It helps testers to export recorded scripts in HTML, Java, Ruby, RSpec, Python, C#, JUnit, and TestNG, among other languages. Unfortunately, Selenium IDE has a narrow reach, and the test scripts it generates aren’t either stable or portable.
This concludes our list of the most popular Selenium interview questions and answers. Reading this list will undoubtedly help you in tightening up your Selenium interview preparation.
