javascript - Jest setTimeout 不暂停测试

Question

it('has working hooks', async () => {
  setTimeout(() => {
    console.log("Why don't I run?")
    expect(true).toBe(true)
  }, 15000)

我已经查看了这个答案、Jest 文档和几个 GitHub 线程:

Disable Jest setTimeout mock

此时，超时内的函数没有运行。 我怎样才能让 Jest 暂停执行测试 15 秒，然后运行内部函数？

谢谢!

Answer 1

it('has working hooks', async () => {
  await new Promise(res => setTimeout(() => {
    console.log("Why don't I run?")
    expect(true).toBe(true)
    res()
  }, 15000))
})

或

it('has working hooks', done => {
  setTimeout(() => {
    console.log("Why don't I run?")
    expect(true).toBe(true)
    done()
  }, 15000)
})
