Php Laravel通知邮件无法在测试中工作

我正在使用通知在触发通知时向所有用户发送邮件

这在手动“浏览网站”使用（向ContactController提交帖子）中效果很好，但在我的测试中，mail facade声称没有发送邮件

控制器：

发送通知电子邮件的驱动程序似乎没有使用
邮件
外观，这意味着
邮件：：假
不会影响它。相反，它直接调用
Mailable
上的
send
方法，该方法依次调用
Mailer
（邮件驱动程序）上的
send

您可以将
Mailable
实例替换为的实例（这是
Mail:：fake
使用的），但它看起来似乎不适合
mailfeak
是数组的情况（这是
MailChannel
传递给
Mailable
的内容）

幸运的是，Laravel源代码包含了一个示例，说明了他们如何测试发送邮件的通知。他们模拟
Mailer
和
Markdown
实例，并检查传递的参数。你可以做类似的事情，比如：

use Mockery as m;
use Illuminate\Contracts\Mail\Mailable;
use Illuminate\Contracts\Mail\Mailer;
use Illuminate\Mail\Markdown;
use Illuminate\Mail\Message;

class ContactFormTest extends TestCase
{

    protected function tearDown(): void
    {
        parent::tearDown();
        m::close();
    }

    protected function setUp(): void
    {
        parent::setUp();

        $this->mailer = m::mock(Mailer::class);
        $this->markdown = m::mock(Markdown::class);
        $this->instance(Mailer::class, $this->mailer);
        $this->instance(Mailer::class, $this->markdown);
    }

    public function a_mail_is_send_when_the_contact_form_is_used()
    {
        $this->withExceptionHandling();

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

        $this->markdown->shouldReceive('render')->once()->andReturn('htmlContent');

        $this->markdown->shouldReceive('renderText')->once()->andReturn('textContent');

        $data = [
            'name' => 'John Doe',
            'email' => 'email@email.com',
            'message' => 'This is a test message'
        ];

        $notification = new ContactRequestNotification($data);

        $this->mailer->shouldReceive('send')->once()->with(
            ['html' => 'htmlContent', 'text' => 'textContent'],
            array_merge($notification->toMail($user)->toArray(), [
                '__laravel_notification' => get_class($notification),
                '__laravel_notification_queued' => false,
            ]),
            m::on(function ($closure) {
                $message = m::mock(Message::class);
                $message->shouldReceive('to')->once()->with([$user->email]);
                $closure($message);
                return true;
            })
        );


        $response = $this->post('/contact', $data);

        $response->assertStatus(200);

    }
}


就个人而言，我现在更愿意在
ContactRequestNotification
类上对
toMail
方法进行单元测试，因为我认为上面的方法不是很好

use Mockery as m;
use Illuminate\Contracts\Mail\Mailable;
use Illuminate\Contracts\Mail\Mailer;
use Illuminate\Mail\Markdown;
use Illuminate\Mail\Message;

class ContactFormTest extends TestCase
{

    protected function tearDown(): void
    {
        parent::tearDown();
        m::close();
    }

    protected function setUp(): void
    {
        parent::setUp();

        $this->mailer = m::mock(Mailer::class);
        $this->markdown = m::mock(Markdown::class);
        $this->instance(Mailer::class, $this->mailer);
        $this->instance(Mailer::class, $this->markdown);
    }

    public function a_mail_is_send_when_the_contact_form_is_used()
    {
        $this->withExceptionHandling();

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

        $this->markdown->shouldReceive('render')->once()->andReturn('htmlContent');

        $this->markdown->shouldReceive('renderText')->once()->andReturn('textContent');

        $data = [
            'name' => 'John Doe',
            'email' => 'email@email.com',
            'message' => 'This is a test message'
        ];

        $notification = new ContactRequestNotification($data);

        $this->mailer->shouldReceive('send')->once()->with(
            ['html' => 'htmlContent', 'text' => 'textContent'],
            array_merge($notification->toMail($user)->toArray(), [
                '__laravel_notification' => get_class($notification),
                '__laravel_notification_queued' => false,
            ]),
            m::on(function ($closure) {
                $message = m::mock(Message::class);
                $message->shouldReceive('to')->once()->with([$user->email]);
                $closure($message);
                return true;
            })
        );


        $response = $this->post('/contact', $data);

        $response->assertStatus(200);

    }
}
