我已经开始使用mocha了,我对一个特定的测试用例有疑问.这是代码:
var assert = require("chai").assert;
var request = require('supertest');
var http = require("http");
var conf = require("../config/config");
var app = require("../app");
var mongoose = require('mongoose');
var User = mongoose.model('User');
describe('User controller', function(){
describe('POST /register', function(){
it('should return false when the parameters are not unique', function (done) {
request(app)
.post('/user/register')
.send({username:"janette_doe", email:"janette_doe@gmail.com", password:"test123"})
.expect('Content-Type',/json/)
.expect({success:true, redirect:'/user/registerConfirmation'})
.end(function(err, res) {
if (err) {
return done(err);
}
request(app)
.post('/user/register')
.send({username:"janette_doe", email:"janette_doe@gmail.com", password:"test123"})
.expect('Content-Type',/json/)
.expect({success:false}, done);
});
});
});
我期望结果是错误的,因为在数据库中插入用户之后,唯一索引规则应该引发错误.当我运行这个测试时,我得到了这个:{success:true,redirect:’/ user / registerConfirmation’},我应该得到这个:{success:false}.我注意到,当我在每次测试之前没有清除数据库时(在utils.js中),我得到了预期的值.由于异步错误,我是否收到此错误?我怎样才能重写这个测试以确保它有效?
谢谢

util.js包含测试序列的配置:
'use strict';
process.env.NODE_ENV = 'test';
var config = require('../config/config');
var mongoose = require('mongoose');
beforeEach(function (done) {
mongoose.connection.db.dropDatabase();
return done();
});
afterEach(function (done) {
return done();
});
user.js用户模型:
var mongoose = require('mongoose'),
Schema = mongoose.Schema,
var UserSchema = new Schema({
username: {type: String, required: true, unique: true},
email: {type: String, required: true, unique: true},
password: {type: String, required: true},
status: {type: Number, default:0}
});
UserSchema.virtual('date')
.get(function(){
return this._id.getTimestamp();
});
UserSchema.pre('save', function(next) {
//Password encryption ...
});
mongoose.model('User', UserSchema);
user.js(controller)是所有用户路由的控制器.
...
router.post('/register', function (req,res,next){
var newUser = new User({
username: req.body.username
, email: req.body.email
, password: req.body.password
});
newUser.save(function(err){
if(err){
res.send({success: false});
}else{
var newToken = new UserToken({
userId: newUser._id
, email: newUser.email
});
newToken.save(function(err){
if(err){
res.send({success: false});
}else{
res.send({success: true, redirect: '/user/registerConfirmation'});
}
});
}
});
});
...

我已经尝试了end()函数,它仍然无法正常工作.
最佳答案 如何在测试测试套件中链接超级请求 – 第二个请求未正确调用.当您没有清除数据库时,测试在第一个.expect({success:true,…})上失败并且您获得了预期值.
正确的方法是使用.end方法执行第一个请求,检查潜在错误,然后执行第二个请求以查看它是否已失败:
describe('User controller', function(){
describe('POST /register', function(){
it('should return false when the parameters are not unique', function (done) {
request(app)
.post('/user/register')
.send({username:"janette_doe", email:"janette_doe@gmail.com", password:"test123"})
.expect('Content-Type',/json/)
.expect({success:true, redirect:'/user/registerConfirmation'})
.end(function(err, res) {
// Check if first request has failed (it should not!)
if (err) {
return done(err);
}
// Testing the second, not unique request. that should fail
request(app)
.post('/user/register')
.send({username:"janette_doe", email:"janette_doe@gmail.com", password:"test123"})
.expect('Content-Type',/json/)
.expect({success:false}, done);
});
});
});
