Jasmine vs Mocha: What are the differences?

What is Jasmine? DOM-less simple JavaScript testing framework. Jasmine is a Behavior Driven Development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it's suited for websites, Node.js projects, or anywhere that JavaScript can run.

What is Mocha? Simple, flexible, fun javascript test framework for node.js & the browser. Mocha is a feature-rich JavaScript test framework running on node.js and the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases.

Jasmine and Mocha belong to "Javascript Testing Framework" category of the tech stack.

"Can also be used for tdd " is the primary reason why developers consider Jasmine over the competitors, whereas "Open source" was stated as the key factor in picking Mocha.

Jasmine and Mocha are both open source tools. Mocha with 18K GitHub stars and 2.43K forks on GitHub appears to be more popular than Jasmine with 14.4K GitHub stars and 2.12K GitHub forks.

Sellsuki, Onedio, and triGo GmbH are some of the popular companies that use Mocha, whereas Jasmine is used by Coderus, Infoshare, and Ztory. Mocha has a broader approval, being mentioned in 397 company stacks & 268 developers stacks; compared to Jasmine, which is listed in 143 company stacks and 75 developer stacks.

We were able to combine multiple tools with Jest and React Testing Library (e.g. sinon, enzyme, chai). Jest has powerful cli options and increased performance including from parallel testing processes. Migrating was reasonably straight forward as there is a code transformation script to do most of the leg work. Jest's documentation is excellent.

We use Mocha for our FDA verification testing. It's integrated into Meteor, our upstream web application framework. We like how battle tested it is, its' syntax, its' options of reporters, and countless other features. Most everybody can agree on mocha, and that gets us half-way through our FDA verification and validation (V&V) testing strategy.
