04-mikes-ts-setup.md - import path in a `index.test.ts`

[andrewmiroshnichenko]

I followed all steps in a tutorial, and received an TS error Cannot find module '..' or its corresponding type declarations.ts(2307) while trying to do

import { avg, sum3 } from '..';

What I could miss?

Folder structure is

My tests/tsconfig.json internals are

{
  "extends": "../tsconfig.json",
  "references": [
    {
      "name": "my-lib",
      "path": ".."
    }
  ],
  "compilerOptions": {
    "types": [
      "jest"
    ],
    "rootDir": "..",
    "noEmit": true
  },
  "include": [
    "."
  ]
}

and in a Problems tab of VS Code I'm receiving an error
File '/home/stradivari/projects/temp/tests/index.test.ts' is not under 'rootDir' '/home/stradivari/projects/temp/src'. 'rootDir' is expected to contain all source files.

change the import statement to
import { avg, sum3 } from '../src/index';
