Ich verwende Mokka, Chai und versprochenen Chai. Der Test sollte fehlschlagen, tut dies aber nicht. Ich weiß nicht, was falsch läuft, irgendwelche Vorschläge?
const { describe, it } = require('mocha')
const chai = require('chai')
const { expect } = require('chai')
const chaiAsPromised = require('chai-as-promised')
chai.use(chaiAsPromised)
describe('test', () => {
it('must be rejected', async () => {
expect(Promise.resolve('success')).to.rejected
})
})
Ich versuche ein Versprechen zu testen, das abgelehnt werden sollte. Der Test sollte fehlschlagen, aber der Test ist erfolgreich
摘自Chai as Promised 文档
您可以使用
async /await或.then(() => {})在测试中包含多个 Promise。这四个测试将失败：
const { describe, it } = require('mocha'); const chai = require('chai'); const { expect } = require('chai'); const chaiAsPromised = require('chai-as-promised'); chai.use(chaiAsPromised); describe('test', () => { it('must be rejected (1)', () => { return expect(Promise.resolve('success')).to.eventually.be.rejected; }); it('must be rejected (2)', (done) => { expect(Promise.resolve('success')).to.eventually.be.rejected.notify(done); }); it('must be rejected (3)', async () => { await expect(Promise.resolve('success1')).to.eventually.be.fulfilled; return expect(Promise.resolve('success2')).to.eventually.be.rejected; }); it('must be rejected (4)', () => { return expect(Promise.resolve('success1')).to.eventually.be.fulfilled.then( () => expect(Promise.resolve('success2')).to.eventually.be.rejected ); }); });实例：https://stackblitz.com/edit/node- a7t3tx?file=index.js
