如何使用Jest在nest.js应用程序上测试headers请求

npm install --save-dev jest @types/jest

import { Test, TestingModule } from '@nestjs/testing';
import { AppController } from './app.controller';

describe('AppController', () => {
  let appController: AppController;

  beforeEach(async () => {
    const app: TestingModule = await Test.createTestingModule({
      controllers: [AppController],
    }).compile();

    appController = app.get<AppController>(AppController);
  });

  it('should return headers', () => {
    // Your test code goes here
  });
});

import * as request from 'supertest';

it('should return headers', () => {
  return request(appController.getHttpServer())
    .get('/')
    .expect(200)
    .expect((response) => {
      expect(response.headers['content-type']).toContain('application/json');
      // Add more assertions for other headers if needed
    });
});

npx jest
