Jest vs Jasmine vs Mocha: What are the differences?

Jest, Jasmine, and Mocha are all JavaScript Testing Frameworks, used to test JavaScript code. Jest is used by Facebook for all React testing and works “out of the box” for any React project. Mocha runs on Node.js. Jasmine does not rely on browsers, DOM, or any particular framework, allowing it to test all JavaScript code with no dependencies. All three are open source.
