Laravel模擬失敗測試

Question

我只是想知道，我正在嘗試創建這個測試用例，但是它一直失敗。 使用Mockery是否有我缺少的東西？

 /** @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);
}

這是我得到的錯誤：

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

正好1次，但稱為0次。

就是想，

謝謝！

假設您要測試Bar類，該類取決於Foo類：

/**
 * 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();
    }
}

現在在bar測試中，您會說，當您運行barAction()您期望fooAction()被調用並返回模擬結果：

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

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

$result = $barTest->barAction();

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

在該示例中，我在構造函數級別傳遞了Foo對象，但是如果在函數級別傳遞它，其工作原理相同

我希望這有幫助！
