Add back the jest config file or fix the issue with importing jest inside the tests

[Reblixt]

This happends now when i create a new npx create-solana-dapp

and do these commands in the followoing order:

cd ./new-dapp/anchor
anchor build
anchor test

if i do as the complier suggested. remove import @types/jest and add import 'jest'; then the test works but... my editor looks like this instead. a wall of syntax error on every ( describe, it, expect)

I have tried to have both import "@types/jest"; import "jest";

Imported but the test fails anyway because of the import.

v20.17.0 LTS

Thanks for creating the issue, I will get this fixed after the weekend!

Just started digging into this.

I got the tests running by:

• removing import '@types/jest' from the spec - I did not replace it with import 'jest'.
• removing the typeRoots key from anchor/tsconfig.json.

With these changes, the tests run. I do still see similar errors when I open the project in nvim, strangely enough WebStorm and VS Code don't show them.

I'll keep digging into this, but the above 2 steps might unblock you.

I've made the above changes (and a bunch more) in the relevant template and set up a GitHub Actions workflow to make sure the tests run on CI.

I hope this fixes the issues with newly created projects. If it doesn't, don't hesitate to ping me here and I'll re-open the issue investigate further.
