PHPUnit + Laravel 5.2 +屬性未正確返回

Question

User.php-漂亮的香草hasMany關系：

public function transactions()
{
    return $this->hasMany('App\Transaction');
}

UserTest.php：

public function testTransactionsAttribute()
{
    $user = Auth::user();

    // Verify logged in user is expected user.
    $this->assertTrue($user->username == 'something');

    // Pay something.
    $transaction = $user->payMembershipFee();

    // Verify transaction is in database
    $this->seeInDatabase('transactions', ['amount' => 50, 'user_id' => $user->id]);

    // Verify transaction belongsTo relationship
    $this->assertTrue($transaction->user->username == 'something');

    // Verify user hasMany relationship - fails
    $this->assertTrue($user->transactions->count() > 0, 'The user should have at least one transaction associated.');
}

這就是有趣的地方（我沒有修改數據庫表-剛離開PHPUnit並切換到Tinker）：

$ php artisan tinker

抓取用戶（已驗證是通過測試創建的同一用戶）：

$user = App\User::first()

復制/粘貼斷言：

$user->transactions->count()
=> 1

另外，當我在本地手動執行步驟時，它也可以工作。 因此，Laravel 5.2似乎按預期運行。 但是，PHPUnit不是。

我想知道是否有可能會丟失Laravel 5.2和PHPUnit相互配合的方式？

從模型外部（例如，在測試本身中）：

$user = $user->fresh();

從模型內部，不能執行以下操作：

$this = $this->fresh();

因此，在為用戶創建事務的方法中：

public function createTransaction()
{
    $transaction = new Transaction;
    ...
    $transaction->save();

    // Refresh the relationship specifically        
    $this->load('transactions');

    // There is also fresh([])
    // which is supposed to be able to accept multiple relationships

    return $transaction;
}
