我想开始在我的项目中结合Jest测试，但是我很难让这个测试工作。当我运行它时，我得到这个错误抛出。
thrown: "Exceeded timeout of 5000 ms for a test.
Use jest.setTimeout(newTimeout) to increase the timeout value, if this is a long-running test."

我的app.js文件看起来像这样
const express = require("express");
const colors = require('colors');
const errorHandler = require('./middleware/error');
const morgan = require('morgan');
const localdb = require('./db/bootcampDB');
const fileupload = require('express-fileupload');
const path = require('path');
const cookieParser = require('cookie-parser');
//ROUTES
const reviews = require('./routes/reviews');
const auth = require('./routes/auth')
const bootcamps = require('./routes/bootcamps');
const courses = require('./routes/courses')
const users = require('./routes/users');
const app = express();
app.use(express.json())
if(process.env.NODE_ENV === 'development'){
app.use(morgan('dev'));
}
localdb();
app.use(fileupload())
//SET static folder
app.use(express.static(path.join(__dirname, 'public')));
app.use('/api/v1/bootcamps', bootcamps);
app.use('/api/v1/courses', courses);
app.use('/api/v1/auth', auth);
app.use('/api/v1/users', users);
app.use('/api/v1/reviews', reviews);
app.use(cookieParser);
app.use(errorHandler)
module.exports = app;
const app = require('./app');
const port = process.env.PORT || 4000
const server = app.listen(port, ()=>{
console.log(`Server running in ${process.env.NODE_ENV} mode on port ${port}`.yellow.bold);
})
process.on('unhandledRejection',(err, promise)=>{
console.log(`Error: ${err.message}`.red);
//Close server
server.close(()=>{
process.exit(1)
})
})
这个特殊的测试需要通过"/api/v1/users"像这样的路由
router.route('/').get(advancedResults(User), getUsers).post(createUsers);
这行代码在名为uses.js的文件中，该文件位于名为routes的文件夹中。
user.js文件const express = require('express');
const {getUsers,getSingleUsers,createUsers, deleteUsers, updateUsers} = require('../controllers/users');
const User = require('../models/user');
const router = express.Router({mergeParams:true});
const {protect, authorize} = require('../middleware/auth')
const advancedResults = require('../middleware/advancedResults');
router.use(protect);
router.use( authorize('admin'))
router.route('/').get(advancedResults(User), getUsers).post(createUsers);
router.route('/:id').get(getSingleUsers).put(updateUsers).delete(deleteUsers);
module.exports = router;
方法本身在一个名为user.js的文件中，该文件位于controllers文件夹中。它看起来像这样
// @desc Create user
// @route POST /api/v1/auth/users
// @access Private/Admin
exports.createUsers = asynHandler(async(req, res, next)=> {
const user = await User.create(req.body)
res.status(201).json({success:true, data: user})
});
我所做的一件事是改变被传递到请求中的内容。例如，如果我传入'/api/v1/users'，我不会得到时间错误，而是得到这个错误
expected 201 "Created", got 404 "Not Found"
12 | password:"1234567",
13 | role:"admin"
> 14 | }).expect(201);
| ^
15 |
16 | })

这让我更加困惑，因为我认为我是在告诉程序创建数据，而不是找到它。如果有人能帮助我理解Jest和这里发生了什么，我会非常感激。
感谢我弄明白了其实是别人帮我弄明白的。路由错误。处理步骤Jest不知道该跑哪条路线，当它找不到路线时就会超时。我的请求应该是这样写的
test('Create a new user', async () => {
const response = await request(app)
.post(`/api/v1/auth/register`)
.send({
name: 'alex',
email: 'a@gmail.com',
password: '1234567',
role: 'admin',
}).expect(201);
});
auth.js路由文件
const express = require('express');
const {register, login, getMe, getAllUser,forgotPassword, resetPassword, updateDetails, updatePassword} = require('../controllers/auth');
const { protect } = require('../middleware/auth');
const router = express.Router();
router.get('/allusers',getAllUser);
router.post('/register', register);
router.post('/login', login);
router.get('/me', protect, getMe);
router.post('/forgotPassword', forgotPassword);
router.put('/resetpassword/:resettoken', resetPassword);
router.put('/updatedetails', protect, updateDetails);
router.put('/updatepassword', protect, updatePassword);
module.exports = router;
