babel-plugin-module-resolver aliases + jest watch bug

See original GitHub issue

Here is the demo repo: https://github.com/cloud-walker/jest-module-resolver-bug steps to reproduce the bug are listed in the readme file.

What is the current behavior? jest --watch -o will ignore deps imported using babel-plugin-module-resolver

What is the expected behavior? I’m not sure if its possible, maybe I have to use the moduleNameMapper trick to make it work instead, but maybe it could work, so I’m notifying it.

Jest will not make assumptions on aliases based on the babel plugins you use. You’ll need to tell Jest how to resolve these absolute aliases using moduleNameMapper:

  "jest": {
    "moduleNameMapper": {
      "@/(.*)": "<rootDir>/source/$1"
    }
  }

You’ll also need to remove empty jest.config.js because Jest prioritizes it over package.json

why is this closed? I’m facing the same issue. It makes much more intuitive sense for alias configuration to be inherited from babel config when babel-jest is used
