* * unit: `boolean`, default `true` - Laravel will run in unit testing mode.
* * environment: `string`, default `testing` - When running in unit testing mode, we will set a different environment.
* * start: `string`, default `bootstrap/start.php` - Relative path to start.php config file.
* * root: `string`, default ` ` - Root path of our application.
* * filters: `boolean`, default: `false` - enable or disable filters for testing.
