We are progressing towards an era of automation. Every company, be a startup or a large-scale enterprise, they are all striving to incorporate automation testing in their release cycles as efficiently as they can. Reason being, simply because automation testing drastically reduces the effort involved in validating repetitive test scenarios. JavaScript is no more referred to as a developer-only programming language. With the increasing demand for automation testing, JavaScript testing frameworks have emerged for fulfilling different purposes, some are fit for unit testing, while others are made for E2E(End-to-End) testing. It is no wonder that automation testers throughout the globe have become pretty fond of these JavaScript automation testing frameworks. The variety of JavaScript automation testing frameworks made available for automation testers have become a cause of confusion for many. It is only natural, the more options you have in front of you, the more time it will take for you to decide which JavaScript automation testing framework fits the best for you. Don’t worry though! I am going to highlight the top 8 JavaScript automation testing frameworks that make testing easier based upon your testing requirements. You can also read our other blog on Top JavaScript frameworks for 2019 where we have talked about front-end, back-end, and testing suitable frameworks.

1. Jest
• Rated as number #1 JavaScript automation testing framework for
2018 by the stateofjs survey.
• Jest was developed by Facebook and used to test JavaScript
codes, especially applications developed using React JS.
• The biggest benefit of using Jest is the out of the box experience
of minimal configuration and setup since it comes with a mocking
support an assertion library. Just like any new testing libraries,
the test cases are written using the behavior-driven development
approach.
