The watcher includes an interactive command-line interface with the ability to run all tests, or focus on a search pattern. It is designed this way so that you can keep it open and enjoy fast re-runs. You can learn the commands from the “Watch Usage” note that the watcher prints after every run:

> \*Although we recommend running your tests in watch mode during development, you can disable this behavior by passing in the `--no-watch` flag. In most CI environments, this is handled for you (see [On CI servers](#on-ci-servers)).
## Version Control Integration
By default, when you run `npm test`, Jest will only run the tests related to files changed since the last commit. This is an optimization designed to make your tests run fast regardless of how many tests you have. However it assumes that you don’t often commit the code that doesn’t pass the tests.

> If you find yourself doing this often in development, please [file an issue](https://github.com/facebook/create-react-app/issues/new) to tell us about your use case because we want to make watcher the best experience and are open to changing how it works to accommodate more workflows.
For non-CI environments, you can simply pass the `--no-watch` flag to disable test-watching.
The build command will check for linter warnings and fail if any are found.
