Typescript Cannot find module in tests folder

Question

I'm trying to add Jest to test my CLI written in Typescript but whenever I run jest it gives me the following error:

Cannot find module '../src/utils' or its corresponding type declarations.

This is my folder structure:

- tests
  - utils
    - index.ts
- src
  - utils
    - index.ts
  - Profiler.ts
  - index.ts
- webpack.config.js
- jest.config.ts
- tsconfig.json
- package.jsonf

This is my tsconfig.json

{
  "compilerOptions": {
    "target": "ES2016",
    "module": "commonjs",
    "rootDir": "src",
    "allowJs": false,
    "checkJs": false,
    "declaration": true,
    "declarationMap": true,
    "outDir": "./dist",
    "forceConsistentCasingInFileNames": true,
    "strict": true,
    "noImplicitAny": true,
    "alwaysStrict": true,
    "skipLibCheck": true
  }
}

This is my jest.config.ts

import type { Config } from "jest";
import { defaults } from "jest-config";

const config: Config = {
  preset: "ts-jest",
  testEnvironment: "node",
};

export default config;

May be important but VScode also throws this error

And if I click on the path to go to the file, it says file not found and displays this path

I'm pretty sure it has something to do with my tsconfig.json. I've tried adding both to src & test to rootDirs and a bunch of other things that I found online, like adding the paths to include but nothing has solved this.

if you are running the test from tests/utils/index.ts it would be ../../src/utils. As only going back one directory (../) would put you inside tests and then you look for a tests/src which does not exist
