Setting up the development environment

Setting up the development environment for Selenium requires the installation of three main components: Java, Eclipse, and Selenium WebDriver.

1. Java: Selenium is written in Java and requires Java Development Kit (JDK) to be installed on your system. You can download and install the latest version of JDK from the official Java website.

2. Eclipse: Eclipse is a popular Integrated Development Environment (IDE) for Java development. You can download and install the latest version of Eclipse from the official Eclipse website.

3. Selenium WebDriver: Selenium WebDriver is a library for automating web browser interactions. You can download the latest version of Selenium WebDriver from the official Selenium website.

Once you have installed these components, you can set up the development environment by creating a new Java project in Eclipse and adding the Selenium WebDriver library to the classpath. To add the library to the classpath, you can either download the Selenium JAR files and add them to the project build path or you can use a build tool such as Maven or Gradle to manage the dependencies.

After setting up the development environment, you are ready to write and run your first Selenium script. You can use the Eclipse IDE to write and debug your script, and run it using the Selenium WebDriver library to interact with the web browser and automate the test actions.
