@cortinico / @cipolleschi - any idea why the Jest tests would be failing on the test_codegen job only?

There are snapshot format changes between Jest 27 and 29, which we opt out of via jest.config.js changes (snapshotFormat). From the failures it's as if the test_codegen tests are using Jest 29 but without the updated config. I can't see anything in the job spec suggesting it uses a different Jest config though.

Update: I also can't reproduce by re-running with SSH, yarn jest is green there.

(Ah! test_codegen runs under a different working directory so isn't picking up the root config. Thanks Nico for the tip)

Answered offline: test_js and test_codegen are using two different Jest configs. I recall discussing with @cipolleschi about it. Ideally we should unify them under test_js and use a single config.
