Question

因此，我想测试一个控制器，但是我总是遇到相同的错误，而且我对Jest并不真正熟悉。 我使用php，并且已经在phpUnit中进行了一些单元测试，但是使用Jest，我确实在理解操作上遇到了一些麻烦。

这是我的错误消息

<div id="stats">
  <div class="box">
    <i class="fas fa-cloud"></i>
    <p>Members</p>
  </div>
  <div class="box">
    <i class="fas fa-cloud"></i>
    <p>Awards</p>
  </div>
  <div class="box">
    <i class="fas fa-cloud"></i>
    <p>Countries</p>
  </div>
</div>

我的控制器

**我的服务**

import {Controller, HttpStatus, Post, Res, Body, ValidationPipe, Put, Param, Get} from '@nestjs/common';

import {CreateCustomerDto} from './dto/customer/customer.dto';
import {CustomerService} from './customer.service';

@Controller('customer')
export class CustomerController {
    constructor(private readonly customerService: CustomerService) { }

    @Post()
    async createPost(@Res() res, @Body(ValidationPipe) createCustomerDto: CreateCustomerDto ) {
        const customer = await this.customerService.createCustomer(createCustomerDto);
        return res.status(HttpStatus.OK).json({
            customer: customer
        });
    }

    @Put('update/:id')
    async createUpdate(@Param('id') id: string, @Res() res, @Body(ValidationPipe) createCustomerDto: CreateCustomerDto) {

        const customer = await this.customerService.updateCustomer(createCustomerDto, id);

        return res.status(HttpStatus.OK).json({
            customer: customer
        });
    }
}

}

还有我的测试

   import {Injectable} from '@nestjs/common';
import {Model} from 'mongoose';
import {InjectModel} from '@nestjs/mongoose';
import {Customer} from './interfaces/customer.interface';
import {CreateCustomerDto} from './dto/customer/customer.dto';

@Injectable()
export class CustomerService {
    constructor(@InjectModel('customer') private readonly customerModel: Model<Customer>) {}

    async createCustomer(createCustomerDto: CreateCustomerDto ): Promise<Customer> {
        const customer = new this.customerModel(createCustomerDto);
        return customer.save();
    }
async updateCustomer(createCustomerDto: CreateCustomerDto, id: string): Promise<Customer> {
    const customer = await this.customerModel
        .findByIdAndUpdate(id, createCustomerDto, {new: true});

    return customer;

}

正如评论中已经提到的，请确保已正确配置了玩笑。尝试将以下内容添加/修改到您的package.json

  "jest": {
    "moduleFileExtensions": [
      "js",
      "json",
      "ts"
    ],
    "rootDir": "src",
    "testRegex": ".spec.ts$",
    "transform": {
      "^.+\\.(t|j)s$": "ts-jest"
    },
    "coverageDirectory": "../coverage",
    "testEnvironment": "node"
  }

使用Jest在NestJs中进行单元测试
