mock.restoreAll()
此函数会恢复由该 MockTracker 之前创建的所有模拟的默认行为。与 mock.reset() 不同,mock.restoreAll() 不会将模拟与 MockTracker 实例解除关联。
【This function restores the default behavior of all mocks that were previously
created by this MockTracker. Unlike mock.reset(), mock.restoreAll() does
not disassociate the mocks from the MockTracker instance.】
