Controller unit test in slim3

Question

At the outset, I would like to say - I'm new in unit testing in PHP (phpunit). In my new project (slim3 framework) I would like to test my controllers for example LoginController.

My idea is (in unit test method)

Create instance of LoginController
Mock some services in controller (DI)
Execute method which is response for request (in my controllers method __invoke)

My problem is about parameters for __invoke method. In Slim3 callable method for request has two first params:

RequestInterface $request and ResponseInterface $response

How can I create this parameters in my unit test class? I was searching for some examples for this issue but without success.

Any suggestions?

I've found some code in Slim3 tests to mock request:

protected function requestFactory()
{
    $uri = Uri::createFromString('https://example.com:443/foo/bar?abc=123');
    $headers = new Headers();
    $cookies = array(
        'user' => 'john',
        'id' => '123',
    );
    $env = Slim\Http\Environment::mock();
    $serverParams = $env->all();
    $body = new Body(fopen('php://temp', 'r+'));
    $request = new Request('GET', $uri, $headers, $cookies, $serverParams, $body);

    return $request;
}

But I'm not sure that is good way.

Thanks for any help
