我试图测试我的API使用jest和它不工作，同时在 Postman 它的作品成功.这里是我的服务代码：

  1. async function createData(req, res) {
  2.     const newData = req.body
  4.     const data = await prisma.room.create({
  5.         data: {
  6.             roomType: newData.roomType,
  7.             roomImage: newData.roomImage,
  8.             roomStatusId: newData.roomStatusId,
  9.             roomCode: newData.roomCode,
  10.             roomCapacityId: newData.roomCapacityId,
  11.             category: newData.category,
  12.             floor: newData.floor,
  13.             i: newData.i,
  14.             occupied_status: newData.occupied_status,
  15.             overlook: newData.overlook,
  16.             description: newData.description,
  17.             bedSetup: newData.bedSetup,
  18.             connecting: newData.connecting,
  19.             rateCodeId: newData.rateCodeId
  20.         }
  21.     });
  23.     if (!data) {
  24.         return errorResponse(res, 'Error', '', 404);
  25.     }
  27.     return successResponse(
  28.         res,
  29.         `Data has been inserted successfully`,
  30.         data,
  31.         200,
  32.     );
  33. }

下面是我的API测试代码：

  1. describe('POST /room', () => {
  2.     it('Should create a new room', async () => {
  3.         const newData = {
  4.             roomType: "STANDARD",
  5.             roomImage: "https://i.pravatar.cc/300",
  6.             roomStatusId: 1,
  7.             roomCode: 1,
  8.             roomCapacityId: 1,
  9.             category: "well",
  10.             floor: 3,
  11.             i: 2,
  12.             occupied_status: true,
  13.             overlook: "well",
  14.             description: "kamar well",
  15.             bedSetup: "well",
  16.             connecting: "well",
  17.             rateCodeId: 1
  18.         };
  19.         // console.log('createdRoom:', newData);
  21.         const response = await request(app)
  22.             .post('/room')
  23.             .send(newData);
  25.         // Perform assertions
  26.         expect(response.statusCode).toBe(200);
  27.         expect(response.body).toHaveProperty('data');
  28.         expect(response.body.data).toMatchObject(newData);
  29.     });
  30. });

我试过使用 Postman ，它没有错误，我不知道为什么'房间类型'是未定义的。

奇怪的是，它似乎通过 Postman 工作，而不是在测试中。
我已经设置了一个最小的例子来解决你的问题，但看起来效果不错。很可能你的解析器配置不正确，请参阅app.use(express.json())。
下面是一个工作示例（也在StackBlitz上）：

  1. const request = require('supertest');
  2. const express = require('express');
  4. const initializeMockApp = () => {
  5.   const app = express();
  6.   app.use(express.json());
  8.   app.post('/room', (req: any, res: any) => {
  9.     const newData = req.body;
  11.     const data = {
  12.       roomType: newData?.roomType,
  13.     };
  15.     res.status(200).json(data);
  16.   });
  17.   return app;
  18. };
  20. describe('MockApp', () => {
  21.   it('POST /room', async () => {
  22.     // given
  23.     const app = initializeMockApp();
  24.     const newData = { roomType: 'my-room-type' };
  26.     // when
  27.     const res = await request(app).post('/room').send(newData);
  29.     // then
  30.     expect(res.statusCode).toBe(200);
  31.     expect(res.body.roomType).toEqual(newData.roomType);
  32.   });
  33. });
