Yicong-Huang opened a new issue, #4516: URL: https://github.com/apache/texera/issues/4516
## Task Summary Two debugger-adjacent worker RPC handlers have no Python-side unit tests: - **`core/architecture/handlers/control/evaluate_expression_handler.py`** — backs the frontend's "watch variable" feature; builds a runtime context (`self`, `tuple_`, `input_`) from the worker context and forwards it to `ExpressionEvaluator.evaluate`. - **`core/architecture/handlers/control/replay_current_tuple_handler.py`** — `retry_current_tuple` chains the current tuple back onto the front of the input iterator and resumes USER + EXCEPTION pause types (used by debugger "step over an exception" flows). Both are small handlers (~20 lines) but on the critical path for the Udon debugger UX. Same gap pattern as #4509. ## Proposed Action Add `test_evaluate_expression_handler.py` and `test_replay_current_tuple_handler.py` next to the production files, following the pytest pattern from `test_debug_command_handler.py` (mock the worker context fields the handler reads, drive `async` methods via `asyncio.run`). Cover: - **EvaluateExpressionHandler**: runtime context contains the executor as `self`, the current input tuple as `tuple_`, and the current input port id as `input_`; the request expression is forwarded to `ExpressionEvaluator.evaluate`; the evaluator's return value is returned unchanged. - **RetryCurrentTupleHandler** (note: class name differs from file name): when the worker state is `COMPLETED`, the handler no-ops (no chain, no resume); otherwise it prepends the current tuple onto `current_input_tuple_iter` and resumes both USER_PAUSE and EXCEPTION_PAUSE; in either branch returns `EmptyReturn`. ## Priority P3 – Low (test-coverage gap) ## Task Type - [x] Testing / QA -- This is an automated message from the Apache Git Service.
