[노마드 코더 NestJS로 API 만들기] 3 Testing E2E

 

npm run test:e2e

 

테스팅 어플리케이션도 실제 어플리케이션처럼 설정하기 - main.ts의 pipe

beforeAll(async () => {
  const moduleFixture: TestingModule = await Test.createTestingModule({
    imports: [AppModule],
  }).compile();
  
  app = moduleFixture.createNestApplication();
  app.useGlobalPipes(
    new ValidationPipe({
      whitelist: true,
      forbidNonWhitelisted: true,
      transform: true,
    }),
  );
  await app.init();
});
