Best Selenium with Java Interview Questions and Answers in 2023

Attending a job interview can be overwhelming for both freshers and experienced. It is obvious because your entire career graph and earnings rely on this screening process. Besides, aspirants tend to get nervous when technology is in the picture.

Therefore, we decided to ease their nervousness to an extent, by listing down Selenium Java interview questions. But before we move any further, let’s get to the basics.

Why is Selenium preferred with Java?

No doubt, Java is the most preferred language among developers. Most importantly, Java solemnly supports Selenium and has a vast community of contributors who have designed detailed documentation. Due to this, writing a test case is a cakewalk. Also, it is much faster than other languages and used extensively for commercial applications, thus making the integration smooth.

Apart from this, Java virtual machine (JVM) plays a pivotal role in making Java a platform-independent language. With JVM by its side, you can employ it in any Operating environment; just ensure you have installed JVM on it.

We feel these reasons are enough to justify the role of Selenium Automation with Java. Now without any ado, let’s get into the gist of the article – interview questions for Selenium with Java.

Best Selenium Java Interview Questions and Answers

1. What proficiency level of Java is required for Selenium?

When it comes to Test Automation using Selenium, knowledge of Core Java knowledge is enough, and one can waive off the requirement of Advanced Java. Alongside this, one has to be well versed with all Object Oriented Programming (OOPs) Concepts in Java and basics like variables, data types, modifiers, functions, comments, etc.

2. Why are comments used in Selenium Automation with Java?

The whole objective of having comments is to boost the readability of code. It helps in analyzing the working of the code. With apt commenting, the maintenance becomes easier. You know exactly what changes have to be made and where. Commenting comes in handy, especially when writing functions as they are going to be used by other programmers too. With this, the programmers become aware of the flow and spot bugs in no time while debugging.

3. Can you elaborate a little bit about Selenium WebDriver?

A browser automation framework, Selenium WebDriver is a boon for accepting commands and sending them to a browser. The best part is it communicates seamlessly with the browser and in parallel controls it. It directly communicates and controls the browser. Most importantly, it supports various programming languages, among which is Java.

4. What is a Selenium Grid? Can you name a few scenarios in which it is used?

When you wish to run different tests simultaneously on different machines and browsers, then Selenium Grid is used. The reason is, it is a smart proxy server that routes commands to remote web browser cases. Amid this, one server forms the hub that routes JSON test commands to numerous registered Grid nodes.

Now let’s talk about the scenarios where Selenium Grid is used –

  • Executing tests on numerous operating systems.
  • Executing tests on the same browser but with different versions.
  • Executing on numerous browsers.

5. Do you know which WebDriver implementation is the fastest?

When it comes to the fastest implementation mantra, HTML UnitDriver rules the roost. It is lightweight and known as Headless Browser Driver. It resembles other browsers like IE, Chrome, or even Firefox, but the only difference is that it doesn’t have a GUI. Because of this, it is impossible to see the test execution on screen.

6. Can you name a few open-source frameworks that are supported by Selenium WebDriver?

Some of the key open-source frameworks are:

  • JUnit
  • TestNG
  • Robot Framework
  • Cucumber

Yes, once we run this command, it immediately loads a new web page in the current browser window. The website URL is set to “www.cybersuccess.biz.” Interestingly, it will wait until the whole page is loaded before reverting control to the test.

8. Are you aware of the usage of Java Constructor in Selenium Testing?

When it comes to initializing an object, then a special method is called, known as a constructor. A constructor is present in every class, and it is like a block of code executed during object creation. If the declaration of constructor goes amiss for any Java class, then a default constructor is built by the compiler.
Besides, when it comes to Selenium Page Object Model, a Java Constructor comes in handy.

9. Can you mention some of the Loop statements in Java?

Several times, our code contains blocks of statements. They need to be repeatedly executed. In such situations, loop statements come to the rescue. Besides, there are four types of Loop Statements in Java, and they are as follows:

  • do while loop
  • for loop
  • Enhanced for loop
