Question

我有一个我想测试的模块。该模块正在使用其他外部模块，并且开玩笑很难解决它们。

它正在解决基本路径： ./ node_modules /反应标签的输入/ DIST模块/

而不是： ./ node_modules /反应标签的输入/ node_modules /反应-DND

下面是正在发生的事情的简化版本：

错误：

Cannot find module 'react-dnd' from 'reactTags.js'

  at Resolver.resolveModule (node_modules/jest-cli/node_modules/jest-resolve/build/index.js:160:17)
  at Object.<anonymous> (node_modules/react-tag-input/dist-modules/reactTags.js:13:17)
  at Object.<anonymous> (src/tagger/eventtagger.js:5:404)

这是我的测试文件：的 caseevent.test.js

import EventTagger from './eventtagger.js';

eventtagger.js

import ReactTags from 'react-tag-input';

的package.json

我错过了什么？如何让jest-resolve找到或模拟更深层次的组件？

我也有同样的问题。我尝试过的一些事情：

jest.unmock（模块）位于测试文件的顶部在Jest安装文件中填充模块 jest.mock（jest.fn（）=＆gt; {console.log（＆＃39;做某事＆＃39;））最后，这似乎有效，但我无法找到相关文档：

在测试文件的顶部：

/ ** * @providesModule moduleName * /

这似乎认出了我需要的模块。 Jest应该隐含地看到开箱即用的模块，但我还没有那种经验。

jest-resolve嵌套模块解析错误路径：无法从'reactTags.js'中找到模块'react-dnd'
