Mocking Eloquent Queries

Posted 8 months ago by Havocbringer

Hello guys,

I am trying to catch up with Unit Tests. The problem is, 99% of our DB queries are using static methods of the Eloquent models, e.g.: User::join(...)->where(...)->get()

Is there any way to mock these DB calls? I seem to be hitting a rock with PHPUnit and Mockery.

Here's an example (everything is deliberately crammed inside a single method):

/** @test */
public function example()
{
    $mockedUser = \Mockery::mock(\App\Models\Admin\User::class);
    $this->app->instance(\App\Models\Admin\User::class, $mockedUser);
    $mockedBuilder = \Mockery::mock(\Illuminate\Database\Eloquent\Builder::class);
    $this->app->instance(\Illuminate\Database\Eloquent\Builder::class, $mockedUser);
    $mockedUser->shouldReceive('where')->with('id',5)->andReturn($mockedBuilder);

    $emptyUser = new \App\Models\Admin\User();
    $emptyUser->id = 2;

    $mockedBuilder->shouldReceive('first')->once()->andReturn($emptyUser);
    $newUser = \App\Models\Admin\User::where('id',5)->first();
    $this->assertEquals($emptyUser->id, $newUser->id);
}

What am I doing wrong? Is it possible to mock such queries without dependency injection or separating the DB extraction layer?
