Jest is used by Facebook to test all JavaScript code including React applications.

One of Jest's philosophies is to provide an integrated "zero-configuration" experience.

We observed that when engineers are provided with ready-to-use tools, they end up writing more tests, which in turn results in more stable and healthy code bases.

Benefits

Complete and ready to set-up JavaScript testing solution. Works out of the box for any React project.

Instant Feedback

Fast interactive watch mode runs only test files related to changed files and is optimized to give signal quickly.

Snapshot Testing
