What is difference between Mocha.js and Selenium?

Selenium is an open-source test automation framework for testing websites and webapps. Used mainly for end-to-end automation of browser based web testing, it is the most popular automation testing framwork. Mocha.js on the other hand, picks up where selenium gets left off. It extends selenium and is a full featured test automation framework that can used for everything including unit tests, end-to-end tests, integration tests, and much more. In most practical use cases developers and testers do not use just vanilla Selenium. Users usually use both Selenium and frameworks like Mocha.js together.

What are the benefits of Mocha.js for automation?

Mocha.js is a Python based unit test automation framework with great features like annotations, fixtures, test runners, etc. It has in-built classes that help in assertions, testcase management, and organizing test results.

Can Mocha.js be used to run parallel tests?

Latest versions of Mocha.js have out-of-the-box support for running tests in parallel. Mocha.js Jupiter, a component of Mocha.js 5, has a configuration set that can be leveraged to run tests in parallel. For users using older version, they can run tests in parallel using Mocha.js runners, surefire plugin, etc. All these methods are supported at LambdaTest platform. You can run parallel tests at LambdaTest using Mocha.js.

How can I automate with Mocha.js using LambdaTest?

LambdaTest online Selenium Automation Grid enables you to run end-to-end Mocha.js tests on a secure, robust, and scalable Selenium grid infrastructure. With LambdaTest, you can run Python based tests across 3000+ different browsers in parallel. You get higher test coverage and at the same time much shorter build times. Refer to our Mocha.js documentation.

is fantastic. Cross browser and device testingtesting frustration is minimized. You can’t get rid of clients that need ie11 nor can you own every device but lambda test bridge that gap.
