How to test models in laravel?

Question

Laravel

While I don’t know the tests well

There is an ordinary controller

public function index(Request $request)
    {
        $users= User::all();

        return view('index', compact('users'));
    }

How to test it? That is, how to make sure that User::all returns data, just create a mock and check if the all method was called?

Answer 1

http tests https://laravel.com/docs/8.x/http-tests
methods assertOk, assertViewHas users, assertSee user full_name. That will cover the entire request.
If the database is not destroyed before the test, then you can get to the collection of users using the getOriginalContent() method on the response
and check the presence in the contains collection using the method

Answer 2

Never test third party code, only test your own code.
