The most essential benefit is that it can assist in creating high-quality applications and facilitating testing, particularly when it comes to writing functions for simple manipulation.

We will learn how to get started with Selenium automation testing on LambdaTest in this article. But first, let’s discuss what Selenium is and why Selenium automated testing is necessary before moving on with this topic.

What is Selenium testing?

Selenium is the most favored open-source framework for automated testing that allows developers to run unmodified tests on web applications on various platforms, devices, and browsers. With Selenium, testers may easily automate the testing process and quickly provide an application free of bugs.

Without requiring any manual input, Selenium can run the tests frequently and directly in the web browser and control interactions on websites. It assists in removing time- and effort-intensive repetitive manual testing. Selenium Testing refers to testing carried out using the Selenium tool.

Selenium testing supports the most widely used scripting languages, such as Node.js, Java, Python, PHP, Ruby, or C#, enabling developers to write test scripts in the language they are most comfortable with. Additionally, it supports several operating systems, including Windows, Mac, and Linux/Unix, as well as a variety of browsers including Google Chrome, Internet Explorer, Safari, Opera, and Firefox. Selenium is therefore quite advantageous due to its versatility. It is important to keep in mind that Selenium can only be used in browsers; it cannot automate desktop apps.

Selenium Components

The term “Selenium” refers to a collection of tools that are frequently used for cross-browser testing. The Selenium test suite consists of three primary components:

Selenium IDE- The main function of the Selenium IDE (Integrated Development Environment) is to record and perform web application tests on various browsers. It is a browser add-on that makes it simple to write, execute, and debug test scripts with its record and playback features. It is compatible with Windows, Mac OS, and Linux and is accessible as an extension for the Firefox and Chrome web browsers.

Selenium WebDriver- The most crucial tool in the Selenium Suite is Selenium WebDriver. It is the first cross-platform testing framework to automate web application testing. Selenium WebDriver allows for direct communication between the code and the browser. For greater flexibility, it supports many programming languages, including Java, JavaScript, C#, PHP, Ruby, and Python. It also supports a variety of browsers, including Chrome, Safari, Firefox, Internet Explorer, and Opera.

Selenium WebDriver consists of:-

  • API or Application Programming Interface- It uses bindings to convert test scripts from languages like Ruby, Java, Python, etc. to Selenese, the scripting language used by Selenium.
  • Driver – An executable module that launches the test script in a new browser instance.
  • Framework – Support libraries for integrating with test frameworks for programming languages, such as Selenium with TestNG or Selenium with Cucumber.

Selenium Grid- The goal of Selenium Grid was to speed up test execution. It is utilized for distributed or parallel testing. It enables the parallel execution of test scripts across many devices, operating systems, and browsers. This speeds up and greatly simplifies testing for cross-browser compatibility.
