-Files in directories named `fixtures` and `helpers` are ignored, as well as files starting with `_`. This can be useful for having helpers in the same directory as your test files.

 *WARNING: NON-STANDARD BEHAVIOR:* The AVA CLI will always try to find and use your projects local install of AVA. This is true even when you run the global `ava` command. This non-standard behavior solves an important [issue](https://github.com/sindresorhus/ava/issues/157), and should have no impact on everyday use.
