Laravel Feature Testing. Cache mocking not working! CacheManager::driver(), but no expectations were specified

问题

When I test my application with unit-testing cache moking works well. But when I try test my api through feature tests I got an exception.

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

Exactly the same mocking in other unit-tests works without errors.

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