Laravel Mail::assertQueued BadMethodCallException

Question

我正在尝试编写一个 Laravel PHPUnit 测试来检查创建用户后邮件是否已排队。

<?php

namespace Tests\Unit\User;

use App\User;
use Tests\TestCase;
use App\Notifications\UserCreated;
use Illuminate\Support\Facades\Mail;
use Illuminate\Foundation\Testing\WithFaker;
use Illuminate\Support\Facades\Notification;
use Illuminate\Foundation\Testing\RefreshDatabase;

class UserUnitTest extends TestCase
{
    use RefreshDatabase;

    /**
     * check if a user was created in database
     *
     * @return void
     */
    public function testUserCreate()
    {
        $user = factory(User::class)->create();

        $this->assertDatabaseHas('users', [
            'email'             => $user->email,
            'active'            => 0,
            'activation_token'  => $user->activation_token,
            'deleted_at'        => NULL
        ]);
    }

    /**
     * check if email was sent after user was created in database
     *
     * @return void
     */
    public function testEmailSentAfterUserCreated()
    {
        Notification::fake();

        // Assert that no notifications were sent...
        Notification::assertNothingSent();

        $user = factory(User::class)->create();

        // Assert a notification was sent to the given users...
        Mail::assertQueued(UserCreated::class, 1);
    }
}

当我运行此测试testEmailSentAfterUserCreated时，它会引发以下异常。

有 1 个错误：

1) Tests\Unit\User\UserUnitTest::testEmailSentAfterUserCreated BadMethodCallException：方法 Illuminate\Mail\Mailer::assertQueued 不存在。

Mail 类已包含在内，我确信参数是正确的，但我不确定为什么会收到此错误。

如果您想在 Mail::assertQueued() 上进行断言，请使用 Mail::fake()。我面临着同样的问题。我忘记在该特定测试用例中添加 Mail::fake() 。
