我正在创建一个账单跟踪应用程序，该应用程序让用户根据我使用JavaScript创建的条件来创建账单。

我的任务是进行验收测试。

到目前为止，这是我的代码： 我的index.js文件

const express = require('express')
const app = express()
const port = 3000

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/bill');
var MongoClient = require('mongodb').MongoClient
var ObjectID = require('mongodb').ObjectID

app.use(express.json())
app.use(express.urlencoded({ extended: true }));
app.use(express.static('public'))
app.set('view engine', 'pug')
app.set('views', __dirname + '/views');

var billSchema = new mongoose.Schema(
{
  type: { type: String, required: true },
  dueDate: { type: Date, required: true },
  company: { type: String, required: true },
  amtDue: { type: Number, required: true },
  paidStatus: { type: String, required: true }
});

var bill = mongoose.model('bill', billSchema);

var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function() 
{
  app.get('/', (req, res) => 
  {
    bill.find({}, function(err, bills) 
    {
      if (err) 
      {
        console.log(err)
        res.render('error', {})
      } 
      else 
      {
        res.render('index', { bills: bills })
      }
    });
  });

  app.get('/bills/new', (req, res) => 
  {
    res.render('bill-form', { title: "New bill", bill: {} })
  });

app.get('/bills/:id/update', (req, res) => 
{
    let id = ObjectID.createFromHexString(req.params.id)

    bill.findById(id, function(err, bill) 
    {
      if (err) 
      {
        console.log(err)
        res.render('error', {})
      } 
      else 
      {
        if (bill === null) {
          res.render('error', { message: "Not found" })
        } else {
          res.render('bill-form', { title: "Update bill", bill: bill })
        }
      }
    });
});

app.post('/bills/new', function(req, res, next) {
    let newbill = new bill(req.body);
    newbill.save(function(err, savedbill)
    {
      if (err) 
      {
        console.log(err)
        res.render('bill-form', { bill: newbill, error: err })
      } 
      else 
      {
        res.redirect('/bills/' + savedbill.id);
      }
    });
});
app.get('/bills/:id', (req, res) => 
{
    let id = ObjectID.createFromHexString(req.params.id)

    bill.findById(id, function(err, bill) 
    {
      if (err)
      {
        console.log(err)
        res.render('error', {})
      } 
      else 
      {
        if (bill === null) 
        {
          res.render('error', { message: "Not found" })
        } 
        else 
        {
          res.render('bill-detail', { bill: bill})
        }
      }
    });
});

app.post('/bills/:id/update', (req, res, next) => 
{
    let id = ObjectID.createFromHexString(req.params.id)
    bill.updateOne({"_id": id}, { $set: req.body }, function(err, details)
    {
        if(err)
        {
            console.log(err)
            res.render('error', {})
        }
        else
        {
            res.redirect('/bills/' + id)
        }
    });
});

app.post('/bills/:id/delete', (req, res) => 
{
    let id = ObjectID.createFromHexString(req.params.id)
    bill.deleteOne({_id: id}, function(err, product)
    {
        res.redirect("/")
    });
});

app.post('/api/bills', (req, res) => 
{
    let newbill = new bill(req.body)

    newbill.save(function (err, savedbill) 
    {
        if (err) 
        {
            console.log(err)
            res.status(500).send("There was an internal error")
        }
        else 
        {
            res.send(savedbill)
        }
    });
});

app.post('/api/bills', (req, res) => 
{
    bill.find({}, function(err, bills)
    {
        if(err)
        {
            console.log(err)
            res.status(500).send("Internal server error")
        }
        else
        {
            res.send(bills)
        }
    });
});

app.get('/api/bills', (req, res) => 
{
    bill.find({}, function(err, bills)
    {
        if(err)
        {
            console.log(err)
            res.status(500).send("Internal server error")
        }
        else
        {
            res.send(bills)
        }
    });
});

app.get('/api/bills/:id', (req, res) => 
{
    let id = ObjectID.createFromHexString(req.params.id)

    bill.findById(id, function(err, bill) 
    {
        if (err) 
        {
            console.log(err)
            res.status(500).send("Internal server error")
        }
        else
        {
            if (bill === null) 
            {
                res.status(404).send("Not found")
            } 
            else 
            {
                res.send(bill)
            }
        }
    });
  });

app.put('/api/bills/:id', (req, res) => 
{
    let id = ObjectID.createFromHexString(req.params.id)

    bill.updateOne({"_id": id}, { $set: req.body }, function(err, details) 
    {
        if (err) 
        {
            console.log(err)
            res.status(500).send("Internal server error")
        } 
        else 
        {
            res.status(204).send()
        }
    });
  });

app.delete('/api/bills/:id', (req, res) => 
{
    let id = ObjectID.createFromHexString(req.params.id)

    Review.deleteOne({"_id": id}, function(err) 
    {
      if (err) 
      {
        console.log(err)
        res.status(500).send("Internal server error")
      } 
      else 
      {
        res.status(204).send()
      }
    });
  });
});



app.listen(port, () => console.log(`Example app listening on port ${port}!`))
module.exports.app = app;
module.exports.schema = bill;

然后我有一个专门用于测试的脚本

let assert = require('assert');
let chai = require('chai');
let chaiHttp = require('chai-http');
let serverAndSchema = require('../index');
let server = serverAndSchema.app
let Bill = serverAndSchema.schema
let should = chai.should();
chai.use(chaiHttp);

describe('Bills', function() {
  describe('/GET bill', function() {

    it('should get the specified bill', function(done) {
      let expectedBill = new Bill({
        type: "Test Type",
        dueDate: "12/3/2018T06:00:00.000Z",
        company: "Test Company",
        amtDue: "100",
        paidStatus: "Test Status"
      });

      expectedBill.save(function(err, savedBill) {
        chai.request(server)
          .get('/api/bills/'+savedBill.id)
          .end((err, res) => {
            res.should.have.status(200);
            res.body.should.be.a('object');
            res.body.should.have.property('type').eql(savedBill.type)
            res.body.should.have.property('dueDate').eql(savedBill.dueDate)
            res.body.should.have.property('company').eql(savedBill.company)
            res.body.should.have.property('amtDue').eql(savedBill.amtDue)
            res.body.should.have.property('paidStatus').eql(savedBill.paidStatus)
            res.body.should.have.property('_id').eql(savedBill.id)
            done();
          })
        });
      });
   });
});

数据已添加到我的数据库中，但是在尝试运行测试时出现此错误：

Uncaught TypeError: Cannot read property 'id' of undefined

对此有任何帮助！

当我检查Bill架构时，我发现问题是由您的58格式引起的。因此，保存的mongo失败，并且您获得<?php if ( is_cart() ) : ?> <p class="woocommerce-shipping-destination"> <?php if ( $formatted_destination ) { // Translators: $s shipping destination. printf( esc_html__( 'Estimate for %s.', 'woocommerce' ) . ' ', '<strong>' . esc_html( $formatted_destination ) . '</strong>' ); $calculator_text = __( 'Change address', 'woocommerce' ); } else { echo esc_html__( 'This is only an estimate. Prices will be updated during checkout.', 'woocommerce' ); } ?> </p> <?php endif; ?> 的{​​{1}}，并且当您尝试访问<?php if ( is_cart() ) : ?> <p class="woocommerce-shipping-destination"> <?php if ( $formatted_destination ) { $calculator_text = __( 'Change address', 'woocommerce' ); } ?> </p> <?php endif; ?> 时，它会抛出您得到的错误。

这是解决方案：
