auto generate code templete for unit testing
quick switch to ut code file

Usage

• in workspace right click a file choose command create/switch to UT file
• in editor use shortcut ctl + alt + t to switch/create ut file

Features

• support nest framework ut creation，auto import Test Target Class
• auto import & mock dependency which is injected by construstor
• if test root dir exist base.mock.ts then it will auto added to test file
• auto update test mock dependency when source class add new dependencies

Prerequisite

• file must use sigle quote, formatted
• using nest test framework && jest

Example

• Target Nest Class: business.service.ts

  import { Injectable } from '@nestjs/common';
  import { HttpUtil } from './util/httpUtil';
  
  @Injectable()
  export class BusinessService {
  
      constructor(private readonly httpUtil: HttpUtil) {
      }
  
      async invoke(req): Promise<any> {
          return await this.httpUtil.call(req);
      }
  }
  

• genereated Test class: business.service.test.ts

  require('../base.mock');
  import { Test } from '@nestjs/testing';
  import { BusinessService } from '../../src/business.service';
  import { HttpUtil } from '../../src/util/httpUtil';
  
  describe('test BusinessService', () => {
      let businessService: BusinessService;
  
      class HttpUtilMock {
          // todo: to mock functions
      }
  
      beforeEach(async () => {
          const HttpUtilProvider = {
              provide: HttpUtil,
              useClass: HttpUtilMock
          };
  
          const moduleRef = await Test.createTestingModule({
              imports: [],
              controllers: [],
              providers: [BusinessService, HttpUtilProvider],
          }).compile();
          businessService = moduleRef.get<BusinessService>(BusinessService);
  
      });
  
      test('BusinessService business', async () => {
          // todo mock && call && assert
  
      });
  
  });
