Summary

Because <rootDir> is not workspace-root directory when it has a monorepo structure like Nrwl/Nx, <rootDir>/node_modules is not compatible with that.

Test plan

Does this PR introduce a breaking change?

  • Yes
  • No

If the workspace is not monorepo and jest.config.js is placed at the root directory, the result is not changed. This should help issues at monorepo.

Can you please add an example repo to the examples folder? That will provide a test case for this change.

@ahnpnl does the example mean monorepo workspace, right? Is the name example-app-v12-monorepo ok?

lint needs fixing with lint:fix and snapshot needs to be updated with yarn test -u

sadly Windows is not happy with NODE_OPTIONS, this option seems to work only with Linux/Mac
