About Jest

Jest aims to work out of the box, config free, on most JavaScript projects. Make tests which keep track of large objects with ease. Snapshots live either alongside your tests, or embedded inline. Tests are parallelized by running them in their own processes to maximize performance. Tests are parallelized by running them in their own processes to maximize performance. By ensuring your tests have unique global state, Jest can reliably run tests in parallel. To make things quick, Jest runs previously failed tests first and re-organizes runs based on how long test files take.

    Pros: - very simple learning curve
    - runs tests quickly
    - declarative syntax makes it easy to read what a test should do
    - strong dependency mocking abilities
    - typescript support through plugins
    - easy to integrate with many different JS frameworks
    - good documentation
    - strong cli tooling
    - free

    Cons: - poor at detecting memory leaks or hanging processes that can stop tests from performing well
