我使用NestJS框架。使用@ nestjs / typeorm时,我创建了一个包含用户的存储库。使用这种方法创建存储库,我的e2e测试。使用数据库时,所有数据都已成功保存。连接没有问题。这是我的文件:
app.module.ts
import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { Connection } from 'typeorm';
import { AuthModule } from './modules/auth/auth.module';
@Module({
imports: [
TypeOrmModule.forRoot(),
AuthModule,
],
})
export class AppModule {
constructor(private readonly connection: Connection) { }
}
auth.module.ts
import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { AuthService } from './auth.service';
import { AuthController } from './auth.controller';
import { Users } from '../../entity/Users';
@Module({
imports: [TypeOrmModule.forFeature([Users])],
controllers: [AuthController],
providers: [AuthService],
})
export class AuthModule {}
auth.service.ts
...
// my repo
constructor(
@InjectRepository(Users)
private readonly usersRepository: Repository<Users>,
) { }
...
app.e2e-spec.ts
import { INestApplication } from '@nestjs/common';
import { Test } from '@nestjs/testing';
import * as request from 'supertest';
import { AppModule } from './../src/app.module';
describe('AppController (e2e)', () => {
let app: INestApplication;
beforeAll(async () => {
const moduleFixture = await Test.createTestingModule({
imports: [AppModule],
}).compile();
app = moduleFixture.createNestApplication();
await app.init();
});
it('/ (GET)', () => {
return request(app.getHttpServer())
.get('/')
.expect(404)
.expect('{"statusCode":404,"error":"Not Found","message":"Cannot GET /"}'); //todo fix me
});
});
一切都是按照文档编写的。当您运行npm run test:e2e时,控制台会出现以下错误:
> [email protected] test:e2e /home/nikita/MyFiles/Work/bcs-backend
> jest --config ./test/jest-e2e.json

请帮我!
请务必在app
的示例中使用app.close()
