nestjs - 如何在 e2e 测试期间应用 Global Pipes

Question

使用Test.createTestingModule时如何应用全局管道?

通常情况下，应用程序挂载到 main.ts 时会添加全局管道。 .

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

    app = moduleFixture.createNestApplication()
    await app.init()
    done()
  })

您可以在初始化测试模块之前添加它们:

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

    app = moduleFixture.createNestApplication()

    // Add global pipe here
    app.useGlobalPipes(new ValidationPipe({ transform: true, whitelist: true, forbidNonWhitelisted: true }))

    await app.init()
    done()
  })
