摩卡在 npm 测试中没有失败

Question

您好，我在让我的 mocha 测试项目正常工作时遇到了一些问题。我正在使用 Visual Studio 代码。

当我调试以下 Mocha 代码时，我可以看到两个 ownerid 值在 expect 子句中不匹配，跨过我的 expect 行会触发 emitPendingUnhandledRejections()。

不幸的是，如果我单独进行 npm 测试，所有测试都会通过，而我期望会失败。这是为什么？

it('Get Owner should be all match', () => {

  let ownerdata: any;
  helper.createbasicowner()
    .then((ownerdata: any) => {

      return chai.request(app).post('/GetOwnerByID').send({
        ownerid: ownerdata.ownerid

      }).then((odata: any) => {
        expect(odata.body.ownerid).to.not.eql(ownerdata.ownerid);
      })
    })
});

这是我的 package.json:

 "version": "1.0.0",
 "description": "webservices for ",
 "main": "index.js",
 "scripts": {
  "test": "mocha --reporter spec --compilers ts:ts-node/register test/**/*.test.ts",

你应该让 mocha 通过返回 promise 来等待异步任务完成。

it('Get Owner should be all match', () => {

  let ownerdata: any;
  return helper.createbasicowner()
    .then((ownerdata: any) => {

      return chai.request(app).post('/GetOwnerByID').send({
        ownerid: ownerdata.ownerid

      }).then((odata: any) => {
        expect(odata.body.ownerid).to.not.eql(ownerdata.ownerid);
      })
    })
});
