Laravel Eloquent模型单元测试

Question

我正在尝试编写一个测试用例，用于测试Laravel 4.2中两个Eloquent模型之间关系的关联和分离

这是我的测试用例：

class BookingStatusSchemaTest extends TestCase
{

  private $statusText = "Confirmed";
  private $bookingStub;
  private $statusStub;

  public function testMigrateService()
  {

    $this->createTestData();

    $booking = $this->bookingStub;
    $status = $this->statusStub;

    /**
     * Check that the booking has no status. OK
     */
    $this->assertNull($booking->status);

    /**
     * Check that status has no booking. OK
     */
    $this->assertEquals(count($status->bookings), 0);

    /**
     * Add a status to the booking. OK
     */
    $booking->status()->associate($this->statusStub);

    /**
     * Check that status has a booking. NOT OK - This gives error
     */
    $this->assertEquals(count($status->bookings), 1);

    /**
     * Check that the booking has a status. OK
     */
    $this->assertNotNull($booking->status);

    /**
     * Do NOT delete the status, just set the reference
     * to it to null.
     */
    $booking->status = null;

    /**
     * And check again. OK
     */
    $this->assertNull($booking->status);
  }

  private function createTestData()
  {

    $bookingStatus = BookingStatus::create([ 
        'status' => $this->statusText 
    ]);

    $booking = Booking::create([ ]);

    $this->bookingStub = $booking;
    $this->statusStub = $bookingStatus;

  }

}

当我执行它时，我得到：

There was 1 failure:

1) BookingStatusSchemaTest::testMigrateService
Failed asserting that 1 matches expected 0.

预订型号：

class Booking extends Eloquent {

  /**
  * A booking have a status
  */
  public function status()
  {
    return $this->belongsTo('BookingStatus');
  }

}

BookingStatus型号：

class BookingStatus extends Eloquent
{
  protected $table = 'booking_statuses';
  protected $guarded = [ 'id' ];
  protected $fillable = ['status'];

  /**
   * A booking status belongs to a booking
   */
  public function bookings()
  {
    return $this->hasMany('Booking');
  }

}

这是bookingstatus的迁移架构：

  Schema::create('booking_statuses', function(Blueprint $table)
  {
    $table->increments('id');
    $table->string('status');
    $table->timestamps();
  });

还有预订：

Schema::create('bookings', function(Blueprint $table)
{
  $table->increments('id');
  $table->unsignedInteger('booking_status_id')->nullable();
  $table->timestamps();
});

我需要添加/更改哪些能够在我的测试用例中验证关系？
