如何测试验证管道会在NestJS上抛出格式不正确的请求的expect错误

import { Test, TestingModule } from '@nestjs/testing';
import { INestApplication, ValidationPipe } from '@nestjs/common';
import * as request from 'supertest';
import { AppModule } from '../src/app.module';

describe('AppController (e2e)', () => {
  let app: INestApplication;

  beforeEach(async () => {
    const moduleFixture: TestingModule = await Test.createTestingModule({
      imports: [AppModule],
    }).compile();

    app = moduleFixture.createNestApplication();
    app.useGlobalPipes(new ValidationPipe()); // 添加验证管道
    await app.init();
  });

  it('should throw an error for incorrect request format', async () => {
    const response = await request(app.getHttpServer())
      .post('/your-endpoint')
      .send({ invalidField: 'value' }); // 发送格式不正确的请求

    expect(response.status).toBe(400); // 预期的HTTP状态码为400
    expect(response.body.message).toBe('Invalid request format'); // 预期的错误消息
  });

  afterAll(async () => {
    await app.close();
  });
});
