Selenium WebDriver Introduction

Let’s get started with Selenium. Selenium WebDriver is a functional automation tool that automates web application testing.

Selenium WebDriver automates web browsers and provides a set of APIs that can be used to interact with them. These APIs allow web page navigation, click buttons, enter text into text boxes, and select options from drop-down menus.

WebDriver is cross-platform and supports a variety of operating systems and web browsers. It can automate web browser interactions on Windows, Mac, and Linux machines.

JSON wire protocol

The JSON wire protocol provides a transport mechanism for transferring data between servers and clients. It is the industry standard for various Restful web services.

Selenium Test Scripts

To use Selenium WebDriver, we must first install the appropriate driver for its web browser. Once the driver is installed, we can start writing selenium test scripts. Selenium test script is the test code written in any programming language the driver interprets. Selenium test scripts are written in various programming languages, like Java, Python, C#, and Ruby. The syntax for writing test scripts varies depending on the programming language.
