常见的想当然

mockReset clears call records and replaces the mock implementation with an empty function returning undefined like Jest, rather than reverting to the initial implementation while keeping the spy active

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• assert mockReset on vi.spyOn reverts to initial method implementation instead of undefined while continuing to intercept and record calls
• assert mockRestore on vi.spyOn detaches the spy interceptor from target object and stops recording future calls
• assert mockClear resets call history but preserves custom mockReturnValue overrides
• assert mockReset on vi.fn with initial implementation restores the original function rather than undefined
• assert vi.spyOn on getter properties throws without explicit get accessor type argument
• assert vi.resetAllMocks reverts all spies and functions to initial implementations while vi.restoreAllMocks unhooks spies
