Selenium IDE - A Complete Guide

Let’s take a look at the topics we’ll be covering in this blog:

What is Selenium IDE?

Selenium IDE (Integrated Development Environment) is a plug-in for the Mozilla Firefox web browser for running Selenium scripts. It allows software testing professionals to control the tests, such as record, edit, play, debugs, etc. It consists of the core of Selenium which executes the tests. It does not just control the tests, but it provides an environment for the scripts to run.

Selenium IDE Features

Selenium IDE Features

There are various features available in Selenium IDE:

  • Automatically record test cases – Selenium IDE comes with a feature of automatically recording test cases. It can do that by understanding how a particular web application or website has been interacting with the system. In case you don’t want to use this feature, you may disable it.
  • In-built Assertion Functionality – Users can verify and add asserts to the test scripts which are built on Selenium IDE. These commands are useful for users who want to be thorough with the properties of web pages. A text box with a list of verifying and assert commands pop up every time the user clicks on any element. This list keeps on expanding for as long as the user uses Selenium IDE.
  • Comes with multiple actions – Selenium IDE lets users perform multiple actions using Selenese commands. We’ll talk more about them later in the blog.
  • Responsive web bugs have nowhere to hide – Selenium IDE helps identify the actual case of bugs in the front-end. Applitools Root Cause Analysis can be analyzed by running a Selenium IDE script with the Visual Grid. Once the bug is found, you can click on it to open the Document Object Model (DOM) and Cascading Style Sheet (CSS).
  • Third-party plugins support – Selenium IDE supports third-party plugins. You can use these plugins to upload scripts to a cloud, monitor production application services, etc.
  • Runs from Continuous Integration build scripts – Selenium IDE Runner can easily fit into the CI build scripts. This is only possible if the CI server can call selenium-ide-runner as well as upload the .side file.
  • Selenium IDE is now cross-browser – Selenium IDE is now also available on Google Chrome, Firefox Add-on, and IE Safari.
  • Visually test responsive web apps – Selenium IDE lets users test their web pages on the Visual Grid. It has around 50 emulated devices, browsers as well as viewports.
