api - 使用超测响应错误404的nestjs e2e测试graphql

Question

当我运行 e2e 测试时：

这是

应用程序.Module.ts

@Module({
  imports: [
    GraphQLModule.forRoot({
      cors: {
        origin: process.env.FRONTENDURL,
        credentials: true,
      },
      installSubscriptionHandlers: true,
      autoSchemaFile: 'src/schema.gql',
      context: ({ req, res, url }) => ({
        headers: req.headers,
        res,
        url: req.protocol + '://' + req.headers.host,
      }),
    }),
    ScheduleModule.forRoot(),
    UserModule,
    BusinessModule,
    PrismaModule,
    ReviewModule,
    LikeModule,
    FollowModule,
    ImageModule,
    LocationModule,
    CategoryModule,
    ReportModule,
    ClaimModule,
    FeedModule,
  ],
  controllers: [UserController],
  providers: [ClaimResolver, ClaimService],
})
export class AppModule {}

和 main.ts

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import * as cookieParser from 'cookie-parser';
import { NestExpressApplication } from '@nestjs/platform-express';

async function bootstrap() {
  const app = await NestFactory.create<NestExpressApplication>(AppModule, {
    cors: true,
  });
  app.use(cookieParser('Secret'));
  app.enableCors({
    origin: process.env.FRONTENDURL,
    credentials: true,
  });
  //app.setViewEngine('hbs');
  await app.listen(5000);
}
bootstrap();

所以这是我的

app.e2e-spec.ts

import { Test, TestingModule } from '@nestjs/testing';
import { ExecutionContext, INestApplication } from '@nestjs/common';
import * as request from 'supertest';
import { AppModule } from './../src/app.module';
import { GqlExecutionContext } from '@nestjs/graphql';
import { AuthGuard } from '../src/utils/auth/auth.guard';

const gql = '/graphql';

describe('AppController (e2e)', () => {
  let app: INestApplication;
  beforeAll(async () => {
    const moduleFixture: TestingModule = await Test.createTestingModule({
      imports: [AppModule],
    }).compile();

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

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

it('loged in', async () => {
    const result = await request(app.getHttpServer())
      .post(gql)
      .send({
        query: `mutation login{
        login(data:{
          email:"[e-mail]",
          password: "alaa01151116980",
        }){
          token
          user{
            userName
            id
          }
        }
      }`,
      })
      // .expect(404)
      .expect((response) => {
        expect(response.body.data.login.token).toEqual(
          expect.objectContaining({
            login: {
              token: expect.any(String),
            },
          }),
        );
      });
  });
});

我得到了错误

● AppController (e2e) › loged in

    TypeError: Cannot read property 'login' of undefined

当我将app.e2e-spec.ts文件中的响应更改为：

it('loged in', async () => {
    const result = await request(app.getHttpServer())
      .post(gql)
      .send({
        query: `mutation login{
        login(data:{
          email:"[e-mail]",
          password: "alaa01151116980",
        }){
          token
          user{
            userName
            id
          }
        }
      }`,
      })
      // .expect(404)
      .expect((response) => {
        expect(response).toEqual(
          expect.objectContaining({
            login: {
              token: expect.any(String),
            },
          }),
        );
      });
  });

我收到了回复

我注意到这里有些东西我找不到 404 状态代码，并且不同的 url 端口与我使用的后端 url 不匹配，所以我将超测试请求发送到错误的 url 并收到 {data：“null”} 但我不知道怎么做要解决这个问题 。
