Laravel模拟失败测试

Question

我只是想知道，我正在尝试创建这个测试用例，但是它一直失败。 使用Mockery是否有我缺少的东西？

 /** @test */
function can_store_podcast_thumbnail()
{
    $podcast = factory(Podcast::class)->make([
        'feed_thumbnail_location' => 'https://media.simplecast.com/podcast/image/279/1413649662-artwork.jpg',
    ]);

    $mockedService = Mockery::mock(\App\PodcastUploadService::class);
    $mockedService->shouldReceive('storePodcastThumbnail')
        ->with($podcast)
        ->once()
        ->andReturn(true);

    $podcastUploadService = new \App\PodcastUploadService();
    $podcastUploadService->storePodcastThumbnail($podcast);
}

这是我得到的错误：

Mockery\Exception\InvalidCountException: Method storePodcastThumbnail(object(App\Podcast)) from Mockery_2_App_PodcastUploadService should be called

正好1次，但称为0次。

就是想，

谢谢！

假设您要测试Bar类，该类取决于Foo类：

/**
 * This is the Dependency class
 */
class Foo
{
    public function fooAction()
    {
        return 'foo action';
    }
}

/*
 * This is the class you want to test, which depends on Foo
 */
class Bar
{
    private $foo;

    public function __construct(Foo $foo)
    {
        $this->foo = $foo;
    }

    public function barAction()
    {
        return $this->foo->fooAction();
    }
}

现在在bar测试中，您会说，当您运行barAction()您期望fooAction()被调用并返回模拟结果：

$fooMock = Mockery::mock(Foo::class);
$barTest = new Bar($fooMock);

$fooMock->shouldReceive('fooAction')->andReturn('mockReturn');

$result = $barTest->barAction();

$this->assertEquals('mockReturn', $result);

在该示例中，我在构造函数级别传递了Foo对象，但是如果在函数级别传递它，其工作原理相同

我希望这有帮助！
