laravel Mock 应该被精确调用 1 次但被调用 0 次

Mock should be called exactly 1 times but called 0 times

提问by Grzegorz Gajda

I have weird problem with Laravel 5 and PHPUnit. When I try to mock Laravel's facades (e.g. Auth, View, Mail) I always get this exception:

我对 Laravel 5 和 PHPUnit 有奇怪的问题。当我尝试模拟 Laravel 的外观（例如 Auth、View、Mail）时，我总是遇到此异常：

Mockery\Exception\InvalidCountException: Method send("emails.register", array('user'=>'object(MCC\Models\Users\User)',), object(Closure)) from Mockery_0_Illuminate_Mail_Mailer should be called exactly 1 times but called 0 times.

Mockery\Exception\InvalidCountException：方法 send("emails.register", array('user'=>'object(MCC\Models\Users\User)',), object(Closure)) 来自 Mockery_0_Illuminate_Mail_Mailer 应该被精确调用 1 次但调用了0次。

I have a problem with "should be called exactly 1 times but called 0 times."part. This is my test code:

我有"should be called exactly 1 times but called 0 times."部分问题。这是我的测试代码：

public function testSendEmailToNewUserListener()
{
    $user = factory(MCC\Models\Users\User::class)->create();

    Mail::shouldReceive('send')
        ->with(
            'emails.register',
            ['user' => $user],
            function ($mail) use ($user) {
               $mail->to($user->email, $user->name)
                    ->subject('Thank you for registering an account.');
            }
        )
        ->times(1)
        ->andReturnUsing(function ($message) use ($user) {
            dd($message);
            $this->assertEquals('Thank you for registering an account.', $message->getSubject());
            $this->assertEquals('mcc', $message->getTo());
            $this->assertEquals(View::make('emails.register'), $message->getBody());
        });
}

I put dd($message)in closure because I want to know details about return value (how looks $message->getTo()).

我dd($message)关闭是因为我想知道有关返回值的详细信息（看起来如何$message->getTo()）。

I checked many sources from Google, from Stackoverflow, most people mentioned about

我从 Google 和 Stackoverflow 上查了很多资料，大多数人都提到过

$this->app->instance('Illuminate\Mail\Mailer', $mockMailer)

but even this instruction doesn't help. Most of questions about this problem are not solved. I checked installed extensions, my Laravel is fresh installed (some models, some routes, about 20 tests).

但即使这条指令也无济于事。关于这个问题的大部分问题都没有解决。我检查了已安装的扩展，我的 Laravel 是全新安装的（一些模型，一些路由，大约 20 个测试）。

Also I tried methods like

我也尝试过类似的方法

->atLeast()
->times(1)

or

或者

->atLeast()
->once()

but nothing is works properly. Also instead of

但没有任何工作正常。也代替

Mail::shouldReceive('mail')

I used

我用了

$mailMock = Mockery::mock('Illuminate\Mail\Mailer');
$mailMock->shouldReceive('mail)

but these methods still not work.

但是这些方法还是不行。

Also I found one great advice (there Stackoverflow) but it doesn't work.

我还发现了一个很好的建议（有Stackoverflow），但它不起作用。

Mockery is by default a stubbing library, not a mocking one (which is confusing because of its name).

That means that ->shouldReceive(...) by default is "zero or more times". When using ->once(), you say it should be called zero or one time, but not more. This means it'll always pass.

When you want to assert that it is called once, you can use ->atLeast()->times(1) (one or more times) or ->times(1) (exactly one time)

默认情况下，Mockery 是一个 stubbing 库，而不是一个 mocking 库（因为它的名字而令人困惑）。

这意味着 ->shouldReceive(...) 默认情况下是“零次或多次”。当使用 ->once() 时，你说它应该被调用零次或一次，但不能更多。这意味着它会一直通过。

当你想断言它被调用一次时，你可以使用 ->atLeast()->times(1)（一次或多次）或 ->times(1)（恰好一次）

Looking at your test case:

查看您的测试用例：

public function testSendEmailToNewUserListener()
{
    $user = factory(MCC\Models\Users\User::class)->create();

    Mail::shouldReceive('send')
        ->with(
            'emails.register',
            ['user' => $user],
            function ($mail) use ($user) {
               $mail->to($user->email, $user->name)
                    ->subject('Thank you for registering an account.');
            }
        )
        ->times(1)
        ->andReturnUsing(function ($message) use ($user) {
            dd($message);
            $this->assertEquals('Thank you for registering an account.', $message->getSubject());
            $this->assertEquals('mcc', $message->getTo());
            $this->assertEquals(View::make('emails.register'), $message->getBody());
        });
}

Either:

任何一个：

• Creating the user calls the Mailfacade, in which case you're calling that facade beforeyou're mocking it up.

• 创建用户调用Mail外观，在这种情况下，您在模拟它之前调用该外观。

OR

或者

• You aren't calling the function which calls the Mailfacade.

• 您不是在调用调用Mail外观的函数。

Either way, Mail::shouldReceive('send')should notbe the last thing in the test case.

无论哪种方式，Mail::shouldReceive('send')应该不会是在测试用例的最后一件事。

The error you are getting is because Mailis expecting the call to happen afteryou call ::shouldRecieve(), but it's not - the test case ends, and the Mockeryinstance has never been called.

您收到的错误是因为Mail期望在您调用之后调用发生::shouldRecieve()，但事实并非如此 - 测试用例结束，并且Mockery从未调用过实例。

You could try something like this instead:

你可以尝试这样的事情：

public function testSendEmailToNewUserListener()
{   
    $testCase = $this;

    Mail::shouldReceive('send')
        ->times(1)
        ->andReturnUsing(function ($message) use ($testCase) {
            $testCase->assertEquals('Thank you for registering an account.', $message->getSubject());
            $testCase->assertEquals('mcc', $message->getTo());
            $testCase->assertEquals(View::make('emails.register'), $message->getBody());
        });

    $user = factory(MCC\Models\Users\User::class)->create();
}

To integrate Mockery with PhpUnit, you just need to define a tearDown() method for your tests containing the following:

要将 Mockery 与 PhpUnit 集成，您只需为包含以下内容的测试定义一个 tearDown() 方法：

public function tearDown() {
    \Mockery::close();
}

This static call cleans up the Mockery container used by the current test, and run any verification tasks needed for your expectations.

此静态调用会清理当前测试使用的 Mockery 容器，并运行您期望所需的任何验证任务。
