这是我的测试代码。我正在测试一个API。问题是" after“钩子正在工作,并在测试结束后删除数据库。但是“之前”的钩子不起作用。这里有什么问题?我试过了,但找不到问题所在。我试着只用一个虚拟测试来运行之前的钩子,比如在控制台中记录一些东西。也不管用。
const chai = require('chai');
const { assert } = require('chai');
const chaiHttp = require('chai-http');
const mongoose = require('mongoose');
mongoose.Promise = global.Promise;
require('../resolvedir');
const User = require('models/User');
const server = require('bin/www');
const testData = require('./test_data');
chai.use(chaiHttp);
describe('Empty User Collection before test', function () {
it('should drop User Collection before test starts', function () {
before(function (done) {
User.collection.drop();
done();
});
});
});
describe('Testing /registration end point', () => {
it('should return a valid JWT token', (done) => {
chai.request(server)
.post('/register')
.send({ name: testData.name, email: testData.email, password: testData.password })
.end((err, res) => {
assert.equal(res.status, 200, 'Http response code is 200');
assert.exists(res.body.auth, 'Auth confirmation message exist');
assert.isTrue(res.body.auth, 'Auth confirmation message is true');
assert.exists(res.body.token, 'JWT token is neither null or undefined');
assert.isString(res.body.token, 'JWT token is string');
done();
});
});
it('should fail registration', (done) => {
chai.request(server)
.post('/register')
.send(testData)
.end((err, res) => {
assert.equal(res.status, 409, 'Http response code is 409');
assert.isString(res.body.message);
assert.equal(res.body.message, 'User Exist');
done();
});
});
});
describe('Testing /login end point', function () {
it('should get a valid JWT token on successful login', function (done) {
chai.request(server)
.post('/login')
.send({ email: testData.email, password: testData.password })
.end((err, res) => {
assert.isString(res.body.token, 'JWT token is string');
done();
});
});
});
describe('Empty User Collection after test', function () {
it('should drop User Collection after test ends', function () {
after(function (done) {
User.collection.drop();
done();
});
});
});

Mongoose和MongoDB支持承诺。chai-http supports promises也是。
before应该驻留在describe块内,而不是it内。Mocha支持异步块的承诺,不需要done。但是这些测试使用了done,而且使用的方式不一致。before是异步的,但done()是同步调用的。只有在测试成功时才调用done(),当断言失败时会导致测试超时。
它应该是:
describe('Empty User Collection before test', function () {
before(function () {
return User.collection.drop();
});
it('should drop User Collection before test starts', function () {
...
});
});和
it('should get a valid JWT token on successful login', function () {
return chai.request(server)
.post('/login')
.send({ email: testData.email, password: testData.password })
.then((res) => {
assert.isString(res.body.token, 'JWT token is string');
});
});等等。
如果应该在Testing /registration end point测试套件中删除一个数据库,那么也应该有删除数据库的before -或者所有测试都可以具有带有before的父describe
describe('Suite', function () {
before(function () {
return User.collection.drop();
});
describe('Testing /registration end point', () => {...})
describe('Testing /login end point', () => {...})
...
