Create the necessary database and enter your database configuration details in both `codeception.yml` and `app/config/config.php`. Run the full test suite with `php vendor/codeception/codeception/codecept run` or use the following composer scripts:
+  - `composer test`: run the full test suite
+  - `composer testf`: run only the functional tests
+  - `composer testu`: run only the unit tests

 ## Credits and Contributing
 This project is largely inspired by the [Laravel project](https://github.com/laravel). Some portions of code in Yarak were taken directly from the Laravel project. Many thanks to @taylorotwell and the rest of the Laravel contributors.
