How to Record Selenium Test Execution Video using Monte Screen Recorder API

Normally we take screenshots and attach them to Reports(HTML Reports or extent reports)
to help you in debugging tests and identifying the cause of test failures.

However, in certain cases, a video showing exact screen states, screen transitions and input as generated by your tests might come in even more handy. Such a video could also help presenting / demonstrating your work to your peers and other stakeholders.

Monte Screen Recorder, a Java library that can assist you in creating videos of your Selenium tests.

In this post, I will show you how to create videos for your test cases.

Installation and configuration of the Monte Screen Recorder is easy.

Simply download the .jar file from here and add it as a dependency to your project.
