MochaJS
MochaJS runs on Node.js and provides support for both front-end and back-end testing. Since it has existed for more than 10 years, it has solid documentation, a wide community, and a lot of online tutorials for easier learning and understanding.
This framework makes asynchronous testing simple by running tests in parallel. That enables accurate reporting and, at the same time, mapping of uncaught exceptions to the correct test cases.
Some of its other benefits include:
- Support for all modern browsers
- Both back-end and front-end testing
- It is open source, which makes it very flexible
NodeJS debugger is supported which makes error tracing easier
However, there are also a few cons to consider for this framework:
Mocha could improve its developer tooling
- It has significantly reduced popularity among the tester community, with the arrival of newer frameworks
- It could do better in terms of overall performance, and onboard features
- Requires a bit more time to set up and configure
