The Top 30 Selenium WebDriver Interview Questions

Selenium is a tool widely used for the automated testing of web applications. 90% of companies use Selenium for UI automation. It’s a popular option because Selenium can be written in many programming languages including Java, JavaScript, C#, and Python. 

In this article, we’ll look at important Selenium questions to help you ace your next job interview. 

1. What is Selenium?

Selenium is a tool for automating everything you can do inside a web browser. It automates functional aspects of web-based applications and can run across all browsers and platforms.

2. Which are the components of the Selenium suite

Selenium is not just a single tool or a utility. Rather, it’s a bundle of multiple test tools, referred to as a suite. Each of the tools is designed to meet specific criteria for testing and testing environments.

The suite package contains the following set of tools:

• Selenium IDE (Integrated Development Environment) – Open-source record and playback test automation for the web. This is distributed as a plug-in to Firefox and Chrome.
• Selenium RC (Remote Control) – Selenium RC is a server that allows a user to build test scripts in a desired programming language. It also enables test scripts to be performed across a wide spectrum of browsers.
• Selenium WebDriver – WebDriver is an entirely different tool, with different advantages over Selenium RC. WebDriver interacts directly with the web browser and makes use of its native compatibility to automate. 
• Selenium Grid – Selenium Grid is used to simultaneously distribute the test execution on multiple platforms and environments.
