Feature request: aliased fixture dependences

[santilin]

What steps will reproduce the problem?

Following example in Testing: fixtures,

I can do:

$profile = $I->grabFixture('profiles', 'user1');

But I can not grab a user which is dependent on profileuser:

$user = $I->grabFixture('user', 'user1');

because I get the error "User fixture not loaded".

To grab a user fixture, I have to do:

$user = $I->grabFixture('tests\fixtures\UserFixture', 'user1');

Which is cumbersome.

If I define dependent fixtures with an alias:

namespace app\tests\fixtures;

use yii\test\ActiveFixture;

class UserProfileFixture extends ActiveFixture
{
    public $modelClass = 'app\models\UserProfile';
    public $depends = [**'user'** => 'app\tests\fixtures\UserFixture'];
}

and add these lines to yii2/test/FixtureTrait.php:

+                                               if( is_string($alias) ) {
+                                                       $aliases[$dep] = $alias;
+                                               }
+                                               // need to use the configuration provided in test case
+                                               $stack[] = isset($config[$dep]) ? $config[$dep] : ['class' => $dep];
+                                       }
+                               }
                 // if the fixture is already loaded (ie. a circular dependency or if two fixtures depend on the same fixture) just skip it.

Then I can do

$user = $I->grabFixture('user', 'user1');

By the way, the manual page Testing: fixtures, is misleading as is creating a UserProfileFixture that ends up using the user.php file with user data instead of using a userprofile.php data file with user profile data.
