Getting Started

Selenium WebDriver is a popular open-source web application automation tool.  Selenium is used as a functional automation tool to automate web application testing. It provides tools and APIs that allow developers and testers to simulate user interactions, validate functionality, and perform various web application testing tasks.


WebDriver provides a programming interface to control web browsers. It enables the testing team to automate browser actions and interact with the web elements as if they were real users. It communicates directly with the web browser using the browser’s native support for automation.

WebDriver supports various web browsers like Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, Opera, etc.

Taking Screenshot

To get started, let’s use this article to demonstrate a specifically customized screenshot capture feature in the TestNG Automation framework. An awesome capability is to capture screenshots when an Assert fails with the TestNG Framework. In the Assert lifecycle, you can write custom assertions in TestNG by overriding the onAssertFailure() method.

Selenium Grid 3.0

We can use the Selenium grid for distributed testing. A distributed test distributes tests across multiple physical and/or VM’s so that tests can run in parallel. Distribution of tests cuts down the time required for running tests.
