PHP Mock a class that implements an interface

I am trying to test a factory that it returns the correct instance. But ApiAuthRequest class has to implement a specific interface in order for the test to succeed. How I can do it?

I have tried to create a class in the test, which works but I am not sure if it's the right way.

public function factory_returns_correct_instance(AllowedHttpMethod $httpMethod): void
{
    $request = $this->partialMock(ApiAuthRequest::class, function(MockInterface $request) {
        $request->shouldReceive('getModel')->andReturn($this->model);
    });

    $restrictor = ModelRestrictionFactory::create($request, $httpMethod);
    $this->assertInstanceOf(ModelSystem::class, $restrictor);
}

// If I do this in the test class, test works.

class ApiAuthRequest  implements HasModelSystemRestriction
{

}

This is possible by using \Mockery::mock(); where the first argument is the class followed by the interface.

public function factory_returns_model_system_instance(AllowedHttpMethod $httpMethod): void
    {
        $request = \Mockery::mock(ApiAuthRequest::class, HasModelSystemRestriction::class);
        $request->shouldReceive('getModel')->andReturn($this->model);
        $request->shouldReceive('instanceof')->with(HasModelSystemRestriction::class)->andReturn(true);

        $restrictor = ModelRestrictionFactory::create($request, $httpMethod);

        $this->assertInstanceOf(ModelSystem::class, restrictor);
    }
