当我尝试测试反应组件LoginForm.js时，我在 LoginForm 中遇到错误。我需要一个joi在 LoginForm 中调用的模块。

TypeError: /home/jaisonjustus/project/captainmice/src/components/LoginForm/test/LoginForm.js: /home/jaisonjustus/project/captainmice/src/components/LoginForm/src/jsx/LoginForm.jsx: /home/jaisonjustus/project/captainmice/node_modules/joi/index.js: /home/jaisonjustus/project/captainmice/node_modules/joi/lib/index.js: /home/jaisonjustus/project/captainmice/node_modules/joi/lib/cast.js: /home/jaisonjustus/project/captainmice/node_modules/joi/lib/string.js: Cannot read property 'buffer' of undefined

文件夹结构

node_modules/
jest-preprocessor.js
src/
  components/
    LoginForm/
      src/
        jsx/
          LoginForm.jsx
        LoginForm.scss
      test/
        LoginForm.js

笑话配置

{ 
      rootDir: 'src',
      testDirectoryName: 'test',
      testPathDirs: [ 'components' ],
      modulePathIgnorePatterns: [ '../node_modules/' ],

      moduleFileExtensions: [ 'js', 'jsx', 'json' ],
      unmockedModulePathPatterns: [ 
        '../node_modules/react’, 
        '../node_modules/joi’
      ] 
    }

这是我的解决方法

这个错误真的很令人沮丧，但现在我jest.autoMockOff();在我的测试文件的顶部使用它并且它工作正常。大概我可以jest.mock(..)在单个文件上手动使用，但我还没有尝试过。

更新：有一个不需要您关闭自动模拟的修复程序。
