 ## [Unreleased]
 
 ### Added
+- Added CI check in `.github/workflows/pr-checks.yml` to ensure all test files follow the naming convention `*_test.py`.This prevents untracked or skipped tests from being missed during CI runs.
 - Add `TokenFeeScheduleUpdateTransaction` class to support updating custom fee schedules on tokens (#471).
 - Add `examples/token_update_fee_schedule_fungible.py` and `examples/token_update_fee_schedule_nft.py` demonstrating the use of `TokenFeeScheduleUpdateTransaction`.
 - Update `docs/sdk_users/running_examples.md` to include `TokenFeeScheduleUpdateTransaction`.
