我尝试为我的简单NestJS后端服务引入e2e测试。我提供了一个用sinon模拟的自定义userService和自定义UserRepository。
这是我的 user.e2e-spec.ts 文件:
import * as request from 'supertest';
import * as sinon from 'sinon';
import { Test } from '@nestjs/testing';
import { INestApplication } from '@nestjs/common';
import { UserService } from '../../src/user/user.service';
import { getRepositoryToken } from '@nestjs/typeorm';
import { User } from '../../src/user/user.entity';
import { TestUtil } from '../../src/utils/TestUtil';
import { createFakeUser } from '../../src/user/test/userTestUtil';
let sandbox: sinon.SinonSandbox;
let testUtil;
describe('User', () => {
let app: INestApplication;
const fakeUser = createFakeUser();
const userService = { findOne: () => fakeUser };
beforeAll(async () => {
sandbox = sinon.createSandbox();
testUtil = new TestUtil(sandbox);
const module = await Test.createTestingModule({
providers: [
{
provide: UserService,
useValue: userService,
},
{
provide: getRepositoryToken(User),
useValue: testUtil.getMockRepository().object,
},
],
}).compile();
app = module.createNestApplication();
await app.init();
});
it(`/GET user`, () => {
return request(app.getHttpServer())
.get('/user/:id')
.expect(200)
.expect({
data: userService.findOne(),
});
});
afterAll(async () => {
await app.close();
});
});
这是我的 user.controller.ts :
import { ApiBearerAuth, ApiUseTags } from '@nestjs/swagger';
import { Controller, Get, Param } from '@nestjs/common';
import { UserService } from './user.service';
import { User } from './user.entity';
@ApiUseTags('Users')
@ApiBearerAuth()
@Controller('user')
export class UserController {
constructor(private readonly userService: UserService) {}
@Get('/:id')
findOne(@Param('id') id: number): Promise<User> {
return this.userService.find(id);
}
}
我用相同的模式编写了一堆单元测试,并且可以正常工作。不知道这个e2e超级测试怎么了。
感谢您的帮助!
更新: 这是我收到的错误消息:

将请求的导入更改为:
<div class="issue-table-container">
<table mat-table [dataSource]="dataSource" class="issue-table"
matSort matSortActive="created" matSortDisableClear matSortDirection="asc">
<ng-container matColumnDef="number">
<th mat-header-cell *matHeaderCellDef>Issue #</th>
<td mat-cell *matCellDef="let row">{{row.number}}</td>
</ng-container>
<ng-container matColumnDef="title">
<th mat-header-cell *matHeaderCellDef>Title</th>
<td mat-cell *matCellDef="let row"><b>{{row.title}}</b>
<button mat-raised-button class="label-button" *ngFor="let label of row.labels" [ngStyle]="setBadgeStyles(label.color)">{{label.name}}</button></td>
</ng-container>
<ng-container matColumnDef="created">
<th mat-header-cell *matHeaderCellDef mat-sort-header disableClear>
Created
</th>
<td mat-cell *matCellDef="let row">{{row.created_at | date:'shortDate'}}</td>
</ng-container>
<ng-container matColumnDef="updated">
<th mat-header-cell *matHeaderCellDef mat-sort-header disableClear>
Updated
</th>
<td mat-cell *matCellDef="let row">{{row.updated_at | date:'shortDate'}}</td>
</ng-container>
<ng-container matColumnDef="estimate">
<th mat-header-cell *matHeaderCellDef mat-sort-header disableClear>
Estimate
</th>
<td mat-cell *matCellDef="let row">{{row.estimate}}</td>
</ng-container>
<ng-container matColumnDef="pipeline">
<th mat-header-cell *matHeaderCellDef mat-sort-header disableClear>
Pipeline
</th>
<td mat-cell *matCellDef="let row">{{row.pipeline}}</td>
</ng-container>
<tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
<tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
</table>
</div>
在测试中,将:id替换为数字:
import request from 'supertest';
在控制器中:
it(`/GET user`, () => {
return request(app.getHttpServer())
.get('/user/1') // pass here id, not a string
.expect(200)
.expect({
data: userService.findOne(),
});
});
现在应该可以使用。
