javascript - 开玩笑 - 模拟超时后返回的 Promise

Question

我有这个模块

function waitTimeout(ms: number) {
 return new Promise((resolve) => setTimeout(() => resolve(true), ms));
}


async function verifyUserRecord(userId) {

 await waitTimeout(10000);

 await <some other method call>
 /////////////// more logic /////////////
}

我如何使用 jest 来模拟对 的调用waitTimeout？意思是模拟setTimeout和Promise.resolve？

我尝试使用：

jest.useFakeTimers();

jest.runAllTimers();

jest.runAllTicks();

jest.advanceTimersByTime(60000);

jest.runOnlyPendingTimers();

但他们都没有工作，我不断得到：

Async callback was not invoked within the 20000 ms timeout specified by jest.setTimeout.Timeout - Async callback was not invoked within the 5000 ms timeout specified by jest.setTimeout.Error:

请指教。
