feat: preparation to tests

[giorgiofellipe]

Describe the feature you'd like to request

This project is really amazing, helped me a lot figuring out some issues with pnpm and expo in a monorepo. So many thanks to you all.

Although, I'm still experience tons of errors when it comes to run my tests written using Jest. So I thought it would be great to have tests here as well (no matter the runner), as tests are crucial part of any project.

Describe the solution you'd like to see

Tests boilerplate
