Cannot find module 'setupDevtools' from 'setup.js'

[Nightsd01]

Issue :

I'm developing a react-native SDK. Whenever I attempt to run my tests using npx jest, I see the following error:

 FAIL  src/__tests__/onesignal.test.ts
  ● Test suite failed to run

    Cannot find module 'setupDevtools' from 'setup.js'

      at Resolver.resolveModule (node_modules/jest-resolve/build/index.js:221:17)
      at Object.<anonymous> (node_modules/react-native/jest/setup.js:12:6)

Expected behavior :

I'm not a JS developer (I'm an iOS dev) so forgive my complete ignorance. I am not sure if this is an issue with ts-jest or not.

Debug log:

I set the environmental variable, but ts-jest.log is no where to be found?

Minimal repo:

Here is our SDK: https://github.com/geektimecoil/react-native-onesignal/tree/typescript_conversion

I am working in the typescript_conversion branch, that is where the issue is.

Same issue here. still investigating it..

I see a similar issue reported in react-native github. I think it might not be related to ts-jest

I think you are right - I'll be closing this issue since it probably is an issue with jest and not this repo.

Same here @Nightsd01 do you solved it?

Several bugfixes were needed, and I managed to get the tests running:

• Eliminates unknown "export" token: "Unexpected token export, when import not compiled libraries"

"transformIgnorePatterns": [
    "node_modules/?!(react-router)"
],

• Removed jsdom - no longer emulating browser environment for react native. "TypeError: Cannot set property '_eventListeners' of undefined” with jest"
• Updated: testPathIgnorePatterns to ignore all folders except "src" so we can remove roots: ["src"] which causes: "Cannot find module 'setupDevtools' from 'setup.js'"
