Sample Lumen application with a codeception test, using the codeception-lumen module.
See https://github.com/incube8/codeception-lumen for the module to get codeception tests working with Lumen.
This doesn't quite work completely yet. As a more or less basic test there is one working but I have had to comment out this line:
$I->seeCurrentActionIs('App\Http\Controllers\HomeController@index');
This is because the Laravel\Lumen\Routing\UrlGenerator class doesn't define an action() method -- Lumen routing is a cut down version of the Laravel router so there is a lot of functionality missing or different.
Pull requests gratefully received.
