开玩笑有时找不到模块

Question

实际上，我正在尝试测试功能并收到该错误：

我正在使用的文件：

searchUserService

import { SearchUserService } from '../../src/service/searchUser.service';
import { SearchUserRepository} from '../../src/repository/searchUser.repository'
import { Util } from 'src/util/util'

let userId = '123456'

describe('', () => {
  it('', async () =>{

  const res =  new SearchUserService(new SearchUserRepository(new Util)).searchCredential(userId) 

    expect(res).toBe('')
})
})

package.json

}

searchUser.service.ts

  import { Injectable } from '@nestjs/common';
  import { BaseService } from '********************';
  import { SearchUserRepository } from '../repository/searchUser.repository';

  @Injectable()
  export class SearchUserService extends BaseService {
   constructor(private readonly searchUserRepository: SearchUserRepository) {
    super();
 }

async searchCredential(userId: string) {

  this.logger.info(`[SearchUserService] - searchCredential - userId = ${userId}`, '');

  return await this.searchUserRepository.searchCredential(userId);
}
}

jest.conf.js

        const path = require('path');

    module.exports = {
    rootDir: path.resolve(__dirname, './'),
    verbose: true,
    preset: 'ts-jest',
    testEnvironment: 'node',
    collectCoverage: true,
    coverageDirectory: process.env.JEST_CLOVER_OUTPUT_DIR || './_devops/coverage',
    coverageReporters: ['text', 'clover', 'lcov'],
    collectCoverageFrom: [
        '**/src/**/*.{ts}',
        '!**/spec/**/*.{ts}',
        '!**/tests/**/*.{ts}',
    ],
    moduleFileExtensions: [
        'ts',
        'tsx',
        'js',
        'json',
        'jsx'
    ]
    };

我尝试了其他功能并进行调试，当我开始调试时，错误立即发生并没有任何机会，而其他功能我得到了相同的结果。

这似乎是来自Jest或NestJs的导入错误。

我已经检查了Jest的文档以及一些与我所获得的问题类似的文件，但没有一个解决了我的问题。
