Workers pull jobs from a shared queue, so a worker that finishes early can run a second job in the same process. Flatware::RSpec.run ends each job with ::RSpec.reset, which sets RSpec.configuration to nil. On the next job --require spec_helper is a no-op (already required), so the new configuration has none of the config.includes or hooks from spec_helper. Specs then fail with errors like undefined method 'stub_request' (WebMock), missing FactoryBot methods, and so on.

Because it depends on worker timing, it shows up as intermittent failures, which is happening to us a lot recently.

Fix: use ::RSpec.clear_examples instead. It clears the example groups and reporter (so nothing runs twice) but keeps the configuration.

Added a test that reproduce the issue by running two jobs through Flatware::RSpec.run in one subprocess against a spec_helper that includes a helper module.

Disclosure: Built with Claude, but manually verified and submitted.

Please resolve the CI errors

I tried in #126 😄 I think they're all unrelated, it's just that CI is set to fail-fast. Same failures happen on master. It first failed on Rubocop, I threw a fix in for that, now it's the Cucumber incompatibility:
