Overwrite Laravel Http Faker

Question

Is there a way to overwrite values of Http::fake([]) in Laravel during testing. I've noticed that if I set a value during a faker, eg. Http::fake(['url1.com' => Http::response('OK'), 'url2.com' => Http::response('Not Found', 404),]), if for some reason I need to change the value of say url1.com to something else such as ['message' => 'Success'], if I "update" the value by calling Http::fake(['url1.com' => Http::response(['message' => 'Success']) again at a later point, I'd expect the response when I call Http::get('url1.com') to return ['message' => 'Success'] but it instead always returns OK which was the original value set.

Same way if I later call Http::fake(['url2.com' => Http::response(['message' => 'Object found.'])]), I would expect the response when I call Http::get('url2.com') to be ['message' => 'Object found.'] but it'll always return Not found which was the original value set.

You can use achieve this by swapping the Http client

Http::fake(['https://potato.com' => Http::response('Yummy!', 200)]);

dump(Http::get('https://potato.com')->body()); // Yummy!

at some point in your test, you can reset the Http Facade using Facade Swap

Http::swap(app(\Illuminate\Http\Client\Factory::class));

now you can change the fake value to whatever you want

Http::fake(['https://potato.com' => Http::response("That's what the dcotor ordered.", 200)]);

dump(Http::get('https://potato.com')->body()); // That's what the doctor orderd.
