node.js - 将 ChaiHttp 与 beforeEach 或 before 方法一起使用

Question

我有一个 NodeJS Express 应用程序，我想对其使用 cookie 进行单元测试。所以我想使用 beforeEach 或 before 来创建 Cookie。

没有任何问题的代码(但没有 before 方法):

import * as chai from 'chai';
import { expect } from 'chai'
import chaiHttp = require('chai-http');


import { app } from '../../server';
describe('Relaties', () => {
    describe('Ophalen alle relaties met: GET /api/ehrm-klantnr/relatie', () => {
        it('should get alle relaties', (done) => {

            let agent = chai.request.agent(app)
            agent
                .put('/api/ehrm-klantnr/medewerker/login')
                .send({ email: 'admin@sfgtest.com', wachtwoord: '<secret>' })
                .then(function (res) {
                    expect(res).to.have.cookie('SESSIONID');
                    // The `agent` now has the sessionid cookie saved, and will send it
                    // back to the server in the next request:
                    return agent.get('/api/ehrm-klantnr/relatie')
                        .set('meta','1')
                        .then(function (res) {
                            expect(res).to.have.status(200);
                            expect(res.body.data[0].vestiging).to.equal('Slib Hoofdkantoor');
                            done();
                        });
                });
        });
    });
});

不运行的是:

import * as chai from 'chai';
import { expect } from 'chai'
import chaiHttp = require('chai-http');

import { app } from '../../server';
 describe('Relaties', () => {
    let agent = chai.request.agent(app);

    describe('First this one', function () {
        beforeEach(function () {
            console.log('outer describe - beforeEach');

            agent
                .put('/api/ehrm-klantnr/medewerker/login')
                .send({ email: 'admin@sfgtest.com', wachtwoord: '<secret>' })
                .then(function (res) {
                    expect(res).to.have.cookie('SESSIONID');
                });
        });
    });

    describe('Ophalen alle relaties met: GET /api/ehrm-klantnr/relatie', () => {
        it('should get alle relaties', (done) => {

            return agent.get('/api/ehrm-klantnr/relatie')
                .set('meta', '1')
                .then(function (res) {
                    expect(res).to.have.status(200);
                    expect(res.body.data[0].vestiging).to.equal('Slib Hoofdkantoor');
                    done();
                });
        });
    });
});

它完全忽略了我的 before 或 beforeEach (这两种方法都不起作用)。也许 chai-http 没有 before 或 beforeEach 支持？我做错了什么？

重组后。

describe('Relaties', () => {
    const agent = chai.request.agent(app);

        beforeEach(function (done) {
            console.log('outer describe - beforeEach');

            agent
                .put('/api/ehrm-klantnr/medewerker/login')
                .send({ email: 'admin@sfgtest.com', wachtwoord: '<secret>' })
                .then(function (res) {
                    expect(res).to.have.cookie('SESSIONID');
                    done();
                });
        });


    describe('Ophalen alle relaties met: GET /api/ehrm-klantnr/relatie', () => {
        it('should get alle relaties', (done) => {

            return agent.get('/api/ehrm-klantnr/relatie')
                .set('meta', '1')
                .then(function (res) {
                    expect(res).to.have.status(200);
                    expect(res).to.be.an('object');
                    expect(res.body.data).to.be.an('array');
                    expect(res.body.data[0]).to.be.an('object');
                    expect(res.body.data[0].id).to.equal(1);
                    done();
                });
        });
    });
});

我仍然收到有关 promise 的错误。

如果这对某人有用，这是最终的解决方案:

 describe('Relaties', () => {
    const agent = chai.request.agent(app);

        beforeEach(function (done) {
            console.log('outer describe - beforeEach');

            agent
                .put('/api/ehrm-klantnr/medewerker/login')
                .send({ email: 'admin@sfgtest.com', wachtwoord: '<secret>' })
                .then(function (res) {
                    expect(res).to.have.cookie('SESSIONID');
                    done();
                });
        });


     describe('Ophalen alle relaties met: GET /api/ehrm-klantnr/relatie', () => {
        it('should get alle relaties', (done) => {

            agent.get('/api/ehrm-klantnr/relatie')
                .set('meta', '1')
                .then(function (res) {
                    expect(res).to.have.status(200);
                    done();
                });
        });
    }); 
});
