NestJS – Test suite failed to run Cannot find module ‘src/article/article.entity’ from ‘comment/comment.entity.ts’

You can tell Jest how to resolve module paths by configuring the moduleNameMapper option, which is useful if you’re using packages like module-alias or if you’re using absolute paths. Add these lines to your Jest configuration:

{
  // ...

  "jest": {
    // ...

    "moduleNameMapper": {
      "^src/(.*)$": "<rootDir>/$1"
    }
  }
}

Now modules that start with src/ will be looked into <rootDir>/, which is the src folder by default (this configured a few lines above). Check out the documentation link above to get ideas of everything you can do with this.

I don’t know what’s wrong with using absolute paths as the other reply said, it’s not only useful but it also works just fine in both NestJS and in Angular.
