我有一个基于 的 React 项目 React Redux Starter Kit .
在 Jest 测试中:当我尝试使用诸如“components/Link”之类的基于根的路径导入某些内容时 - 它不起作用。只有相对路径有效。
放
{ "jest": { "rootDir": "<rootDir>/src" } }
在文件 package.json 中不起作用。
还有别的办法吗？
文件package.json:

文件 package.json 的最终工作 Jest 部分:
"jest": {
"rootDir": "./src/",
"moduleFileExtensions": ["js", "jsx"],
"moduleDirectories": ["node_modules", "bower_components", "src"],
"verbose": true
}
最佳答案
我认为如果你不想使用相对路径，你必须定义额外的moduleDirectories，比如
// package.json
{
"jest": {
"moduleFileExtensions": ["js", "jsx"],
"moduleDirectories": ["node_modules", "bower_components", "src"],
}
}
