[Bug]: ESM + Typescript doesn't work while transpiling testEnvironment #4195
Description
Version
29.1.1
Steps to reproduce
- Clone my repo https://github.com/luiz290788/jest-esm-typescript
- run
NODE_OPTIONS="--experimental-vm-modules" npx jest - test will fail with message:
FAIL ./my-test.test.ts
● Test suite failed to run
my-environment.ts:4:13 - error TS1343: The 'import.meta' meta-property is only allowed when the '--module' option is 'es2020', 'es2022', 'esnext', 'system', 'node16', or 'nodenext'.
4 console.log(import.meta.url)Expected behavior
Expect the testEnvironment to be transpiled as expected using ESM.
Actual behavior
testEnvironment is transpiled as commonjs
Debug log
I tried to post the logs but github complained saying it was too long.
Additional context
It looks like the transpilation happens normally for the tests but the useESM is not affecting the testEnvironment.
