Gitlab CI other results than local

Hi,

I am trying to get a Gitlab CI pipeline up and running for my laravel project. It is running tests, the one problem is: it gives other results than local.

When i run Phpunit in my homestead env it is all green. The functionality works by manual testing. But when ran in Gitlab CI the test fails. Gitlab cannot find a specific column (which does not exists in any situation, as it is a "custom property" appended to the model).

So i got this test:

     /**
     * @test
     */
    public function a_call_can_be_removed()
    {
        $this->signIn();

        $call = create('App\Call');
        $response = $this->withoutExceptionHandling()->json('DELETE', "/call/{$call->id}");

        $response->assertStatus(200);
        $this->assertDatabaseMissing('calls', $call->toArray());
    }

Data structure of Call:

Id, person_id, user_id, comment, status, attention, timestamps.

Model:

class Call extends Model
{

    protected $guarded = [];

    protected $appends = ['statusDescription'];

    public function person()
    {
        return $this->belongsTo(Person::class);
    }

    public function user()
    {
        return $this->belongsTo(User::class);
    }

    public function getStatusDescriptionAttribute()
    {
        return Status::fromCode($this->status)['description'];
    }
}

Locally the test runs green, but Gitlab CI gives me this:

) Tests\Feature\CallControllerTest::a_call_can_be_removed
Illuminate\Database\QueryException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'statusDescription' in 'where clause' (SQL: select count(*) as aggregate from `calls` where (`comment` = Nam consequatur aliquam magni occaecati ullam et. Ipsum eum dolorem occaecati occaecati cumque dicta laborum. In provident ad et nam. Harum neque ut non quia recusandae dolorum. and `status` = 3 and `person_id` = 1 and `user_id` = 2 and `updated_at` = 2018-05-24 20:40:36 and `created_at` = 2018-05-24 20:40:36 and `id` = 1 and `statusDescription` = 'statusDesc'))

My Gitlab ci yml:

stages:
  - test

variables:
  MYSQL_ROOT_PASSWORD: root
  MYSQL_USER: homestead
  MYSQL_PASSWORD: secret
  MYSQL_DATABASE: homestead
  DB_HOST: mysql

cache:
  paths:
  - vendor/
  - node_modules/
  - public/

test:
  stage: test
  services:
    - mysql:5.7
  image: edbizarro/gitlab-ci-pipeline-php:7.2-alpine-lts
  script:
    - composer install --prefer-dist --no-ansi --no-interaction --no-progress
    - npm install
    - cp .env.gitlab .env
    - npm run dev
    - php artisan key:generate
    - php artisan config:cache
    - php artisan migrate:refresh --seed
    - ./vendor/phpunit/phpunit/phpunit -v --coverage-text --colors=never --stderr

Any other Database test goes well.

Totally clueless. Does anyone have any idea?
