如何测试Nestjs拦截器？

import { Test, TestingModule } from '@nestjs/testing';
import { INestApplication, Controller, Get, UseInterceptors } from '@nestjs/common';
import { Interceptor } from './interceptor';
import * as request from 'supertest';

@Controller()
class TestController {
  @Get()
  @UseInterceptors(Interceptor)
  getData() {
    return 'Hello World!';
  }
}

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

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

    app = moduleFixture.createNestApplication();
    app.useGlobalInterceptors(Interceptor);
    await app.init();
  });

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

  it('should intercept the request', async () => {
    const response = await request(app.getHttpServer())
      .get('/')
      .expect(200);

    expect(response.text).toBe('Hello World!');
    // Add more assertions to test the behavior of the interceptor
  });
});
