mocha.js - 如何编写具有超时和异步的摩卡测试

问题描述

createStream 需要获得浏览器的影音权限，所以我不得不推迟这个测试

和createStream回报destroyStream承诺

我想测试destroyStream，这只是没有得到我想要的，有人帮忙吗？

it("my test need to be delayed, and i want to test destroyStream", function () {
  setTimeout(async () => {
    // i need to create stream first
    const publishStream = await createStream();
    expect(streamCenter.previewVideoList.length).to.equal(1);

    // then destory stream
    await zg.destroyStream(publishStream);
    expect(streamCenter.previewVideoList.length).to.equal(0);
  }, 2000); // my test need to be delayed
});

解决方案

it("my test need to be delayed, and i want to test destroyStream", async function () {
    this.timeout(10000); // set timeout 10s
    // i need to create stream first
    const publishStream = await createStream();
    expect(streamCenter.previewVideoList.length).to.equal(1);

    // then destory stream
    await zg.destroyStream(publishStream);
    expect(streamCenter.previewVideoList.length).to.equal(0);
  
});

如果我及时允许权限，这似乎可行。否则它将失败并出现错误“权限被拒绝”
