Installing Selenium on Ubuntu 18.04

Selenium is an open-source testing framework that is widely used for automating web browsers. It allows you to write test scripts in various programming languages, including Python, Java, C#, and Ruby, to automate user interactions with web applications and perform functional testing.

To install Selenium on Ubuntu 18.04, follow the steps below:

1. Open a terminal window.
2. Make sure you have Python installed by running the command: python --version. If Python is not installed, install it by running the command: sudo apt-get install python3.
3. Install pip, the package installer for Python, by running the command: sudo apt-get install python3-pip.
4. Install the Selenium package by running the command: pip3 install selenium.
5. Download the appropriate web driver for your preferred browser. Selenium requires a web driver to interface with the chosen browser. For example, if you are using Google Chrome, download the ChromeDriver from the official website.
6. Extract the downloaded driver and move it to a directory included in the system's PATH variable. For example, you can move it to the /usr/local/bin/ directory.

By following these steps, you have successfully installed Selenium on your Ubuntu 18.04 system. You can now start writing test scripts in your preferred programming language and execute them using Selenium.
