节点打字稿项目中的笑话覆盖率始终返回空 [英] Jest coverage in a node typescript project always returns empty

问题描述

当我尝试获取单元测试用例的覆盖率报告时，我正在从事后端Typescript项目，Jest在终端以及html报告中均未声明任何内容，返回空的覆盖率报告.我还尝试了---coverage --watchAll = false ，但它也返回了空文档.我无法找到此问题的解决方案.有人可以帮我弄清楚我在做什么错吗?

I am working on backend Typescript project when i am trying to get coverage report for unit test case,Jest returns empty coverage report in terminal as well as in html report stating nothing. i also tried with -- --coverage --watchAll=false but it also returns the empty document. I could not able to found a solution for this issue. can anyone help me to figureout what i am doing wrong here?

package.json

"scripts":{
    "unit-test": "jest --config='./config/jest/jest_unit.config.js' --forceExit --detectOpenHandles",
}

jest_unit.config.js

    },
  },

Jest Coverage htm，终端没有显示覆盖线

Jest Coverage htm and terminal shows no coverage lines

推荐答案

能够通过将配置文件移至根目录来解决此问题，这里的配置一切都很好，我不知道为什么玩笑会这样.

Can able to fix this issue by moving config file to root, Everything is good here in configuration, I dont know why jest behaves like this.
