PHP: Mockery Mock variable $user = Auth::user() - php

Question

So, I am trying to mock a service method.
In my service file:
/**
* Return all Api Keys for current user.
*
* #return Collection
*/
public function getApiKeys(): Collection
{
$user = Auth::user();
return ApiKey::where('org_id', $user->organizationId)->get();
}
How do I mock this?
<?php
namespace App\Services;
use PHPUnit\Framework\TestCase;
use Mockery as m;
class ApiKeysServiceTest extends TestCase
{
public function setUp()
{
parent::setUp();
/* Mock Dependencies */
}
public function tearDown()
{
m::close();
}
public function testGetApiKeys()
{
/* How to test? $user = Auth::user() */
$apiKeysService->getApiKeys();
}
}
In my TestCase class I have:
public function loginWithFakeUser()
{
$user = new GenericUser([
'id' => 1,
'organizationId' => '1234'
]);
$this->be($user);
}
What I want to do is test this method. Maybe this involves restructuring my code so that $user = Auth::user() is not called in the method. If this is the case, any thoughts as to where it should go?
Thanks for your feedback.

In your testGetApiKeys method you're not setting up the world. Make a mock user (using a factory as suggested in the comments factory('App\User')->create()), then setup an apiKey again using the factory, then call the method and assert it's what you've setup. An example with your code
public function loginWithFakeUser()
{
$user = factory('App\User')->create();
$this->be($user);
}
public function testApiSomething()
{
$this->loginWithFakeUser();
// do something to invoke the api...
// assert results
}
A good blueprint for the test structure is:
Given we have something (setup all the needed components)
If the user does some action (visits a page or whatever)
Then ensure the result of the action is what you expect (for example the status is 200)
