Simulate HTTP and parse route request parameters in Laravel test sheet

Question

I am trying to create unit tests to test some specific classes. I use app()->make()to create instances for testing. So actually HTTP requests are not required.

However, some of the tested functions need information from the routing parameters, so they will make calls, for example. request()->route()->parameter('info'), and this throws an exception:

Call function member function () at zero.

I played a lot and tried something like:

request()->attributes = new \Symfony\Component\HttpFoundation\ParameterBag(['info' => 5]);  

request()->route(['info' => 5]);  

request()->initialize([], [], ['info' => 5], [], [], [], null);

but none of them worked ...

How can I manually initialize the router and supply some routing parameters to it? Or just make it request()->route()->parameter()available?

Update

@Loek: You didn't understand me. Basically, I do:

class SomeTest extends TestCase
{
    public function test_info()
    {
        $info = request()->route()->parameter('info');
        $this->assertEquals($info, 'hello_world');
    }
}

"". request()->route()->parameter() . . , .
