React-Native / Jest / Convex-test setup issue

Setting up convex-test (0.0.35) in a near fresh RN Expo sdk 52 app Basic test file 
import { describe, expect, test } from '@jest/globals'
import { convexTest } from 'convex-test'
import schema from './schema'

describe('foo', () => {
  test('foo', async () => {
    const t = convexTest(schema)
    expect(true).toBe(true)
  })
})
import { describe, expect, test } from '@jest/globals'
import { convexTest } from 'convex-test'
import schema from './schema'

describe('foo', () => {
  test('foo', async () => {
    const t = convexTest(schema)
    expect(true).toBe(true)
  })
})
I receive an error when running the expo default npm run test command: SyntaxError: Cannot use import statement outside a module

@Riki Know if this is a regression?

I don’t know, but good idea to jnow. I will do a manual bisect with different versions and let you know

@Riki good enough to know if it's every worked, but a bisect would be a dream

Hey @Tom it's strange but after investigation whenever I reinstall whatever version of convex-test, I get this error still

I tried a bunch of things like having convex-text added within the jest config field in my package.json as per recommended by the expo team: https://docs.expo.dev/develop/unit-testing/#additional-configuration-for-using-transformignorepatterns 
  "jest": {
    "preset": "jest-expo",
    "transformIgnorePatterns": [
      "node_modules/(?!((jest-)?react-native|@react-native(-community)?)|expo(nent)?|@expo(nent)?/.*|@expo-google-fonts/.*|react-navigation|@react-navigation/.*|@sentry/react-native|native-base|react-native-svg|convex-test)"
    ]
  },
  "jest": {
    "preset": "jest-expo",
    "transformIgnorePatterns": [
      "node_modules/(?!((jest-)?react-native|@react-native(-community)?)|expo(nent)?|@expo(nent)?/.*|@expo-google-fonts/.*|react-navigation|@react-navigation/.*|@sentry/react-native|native-base|react-native-svg|convex-test)"
    ]
  },
But I still get a similar error.

@Pierre it looks like convex-test doesn't work with Jest, just with vitest
