Laravel 功能测试。缓存模拟不起作用! CacheManager::driver()，但未指定预期

Question

当我使用单元测试缓存移动来测试我的应用程序时，效果很好。但是当我尝试通过功能测试来测试我的 api 时，我遇到了一个异常。

public function testGet()
{
    Cache::shouldReceive('rememberForever')->times(5)->andReturn([]);

    Cache::shouldReceive('has')
        ->once()
        ->andReturn(false);

    Cache::shouldReceive('forever')
        ->once()
        ->andReturn([]);

    $response = $this->getJson('/api/table/get');
    $response->assertOk();

    $responseArr = $response->getOriginalContent();
    $this->assertEmpty($responseArr['table']);
}

Tests\Feature\Controller\API\Site\TableApiControllerTest::testGet Mockery\Exception\BadMethodCallException: Received Mockery_2_Illuminate_Cache_CacheManager::driver(), but no expectations were specified

在其他单元测试中完全相同的模拟工作没有错误。

我在这里找到了答案 - https://github.com/laravel/framework/issues/10803#issuecomment-401611084%23issuecomment-401611084

    $cacheDriver = app('cache')->driver();
    Cache::shouldReceive('driver')->andReturn($cacheDriver);
