Question

User.php - 漂亮的香草有很多关系：

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.');
}

这里有趣的地方（我没有修改数据库表 - 刚离开PHPUnit并切换到Tinker）：

$ php artisan tinker

抓取用户（已验证是与测试相同的用户）：

$user = App\User::first()

复制/粘贴断言：

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

此外，当我在本地手动执行这些步骤时 - 它可以正常工作。因此，Laravel 5.2似乎正如预期的那样发挥作用。但是，PHPUnit不是。

我想知道是否有可能我错过了Laravel 5.2和PHPUnit相互协作的方式？

从模型外部（例如在测试中）：

$user = $user->fresh();

从模型内部不能做出类似的事情：

$this = $this->fresh();

因此，在为用户创建事务的方法中：

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;
}

PHPUnit + Laravel 5.2 +属性无法正常返回
