### Configuration

[](#configuration)

The fastest way to set up Testo in your project is the built-in `init` command:

```
vendor/bin/testo init
```

It will:

- detect your `src/` directory (or prompt for it),
- create `tests/Unit/` if missing,
- generate a minimal `testo.php` next to your `composer.json`,
- register `composer test` and `composer test:` scripts.

For a sub-app layout, point it at the project root: `vendor/bin/testo init --path=app`.
