php - 模拟 Laravel 缓存助手

Question

使用 PESTPHP testing framework , 我想模拟 Laravel 的缓存助手但是当我尝试它时，我得到这样的错误:

Method Mockery_2_Illuminate_Cache_CacheManager::remember() does not exist on this mock object`

我想模拟 rememberForever() 方法，但为什么 remember() 方法会显示在错误消息中？我还尝试将 shouldReceive() 更改为另一种方法，但是 remember() 方法总是被模拟。

这是我的 Controller 代码:

public function index()
{
    $groups = cache()->rememberForever('groups', fn() => Group::pluck('id', 'slug'));

    return view('index', compact(
        'groups'
    ));
}

和我的测试:

it('should return given data on index page', function () {
    /** @var \Tests\TestCase $this */

    $groups = Group::pluck('id', 'slug');

    Cache::shouldReceive('rememberForever')->once()
        ->with('groups', \Closure::class)
        ->andReturn($groups);

    actingAs()->get(route('index'))
        ->assertViewHasAll([
            'groups' => $groups,
        ]);
});

这是显示的错误:

 • it should return given data on index page

当使用 partialMock 时:

  • it should return given data on index page

Answer 1

rememberForever 方法在您使用 cache() 帮助器或 Cache 获得的 CacheManager 实例上不存在 门面。相反，它在 CacheRespository 实例上，您可以使用 Mockery::spy() 来查看以确保调用正确的方法。

public function testCacheWorks(): void
{
    $cacheRepository = Cache::driver();
    $cacheRepositorySpy = \Mockery::spy($cacheRepository);
    Cache::swap($cacheRepositorySpy);

    // do stuff that writes to the cache

    $cacheRepositorySpy->shouldHaveReceived("rememberForever")
        ->once()
        ->with($cache_entry_key, \Closure::class)
        ->andReturns($some_test_object);
}
