How do I install Selenium and set up the environment for testing?

To install Selenium and configure the test environment, we'll use the Eclipse IDE to write test scripts, Java as the programming language, and TestNG as the framework. However, you can use your preferred IDE, programming language and testing frameworks.

Following are the steps to install Selenium.

• Install the latest version of JDK. The JDK contains the JRE (Java Runtime Environment), which is used to write and run Java code. You can get JDK from OpenJDK or Oracle JDK.


• Once the JDK installation is complete, set the environment variables.


• Now install the Eclipse IDE. Here we will use Eclipse IDE for Java Developers.


• Download the Selenium Client Library for Java. Extract the JAR files and save them to a folder.


• Finally, if you are executing your test scripts on your local machine, you must have its respective browser driver installed. However, if you wish to run test on the cloud, you can skip this step.

Once you have installed Selenium, it’s time to set up your project. For demonstration, we will create a Java project in Eclipse.

• Open Eclipse IDE and create a Workspace.


• Create a new Java project by going to File > New > Java Project.


• A pop-up window will appear. Enter your Project name, choose a location to save your project, and select Use an execution environment JRE.


• Now, you need to add Selenium API JAR files to your project. Right-click on the project and select Properties.


• Select Java Build Path and click Add External JARs.


• Add the JARS files for the Selenium Java Client. Navigate to the folder where you extracted the JAR files.


• Once the JARs files are added, click Apply and Close.


You are now ready to write and execute your Selenium scripts.
