How to test a frontend Component Ajax Endpoint

[zoomyboy]

Hello,

I'm trying to test a component in my Plugin that receives an ajax request as usual.
To get the input, the Component uses the input() function, so I probably need to make an actual POST Request and register a route for this.

This is what I have so far:

    public function testItThrowsExceptionWhenNothingFound(): void
    {
        $controller = new Controller();
        $anfrage = new Component();
        $this->app['router']->get('/endpoint', function () {
            return 'A';
        });

        $this->get('endpoint')->dd();
    }

I get <p>page not found</p> as Response, so it probably is not even registering the route...
Am I doing something wrong here? What would be the proper way to set this up?

Cheers
