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.
