Redesign integration test architecture to eliminate async/sync deadlock:
- Run SimulationServer in dedicated background thread with own event loop
- Rewrite TempCo tests as fully synchronous (no @pytest.mark.asyncio)
- Add ServerThread fixture in tests/integration/conftest.py
- Fix Unicode encoding errors (replace deg, mu, +/- with ASCII)
- Optimize temperature points for faster settling (23C, 25C, 27C)
All 3 TempCo integration tests now passing in ~5 minutes total.
- Revert server to only send responses for non-empty strings
Per SCPI protocol: successful commands with no output send nothing
- Add TEMP:RAMP command support to thermal chamber simulator
- Fixes test_multiple_commands and test_physics_engine_integration
TCP server integration tests now passing (8/8).
TempCo integration tests still need work due to async/sync mixing.
Move synchronous test execution to thread pool executor to avoid
blocking the async event loop. This prevents deadlocks when sync
client code tries to communicate with async server in same loop.
Note: Integration tests still experiencing timeouts - needs further
investigation. Unit tests and TCP server communication are working.
- Always send a response (even empty) to prevent client timeouts
- Add pandas-stubs to dev dependencies for mypy type checking
- Server now sends newline-terminated response for all commands
This fixes the mypy CI failure. Integration test failures still need
investigation - likely due to event loop blocking when mixing sync/async.
- Fix import sorting in test_instruments.py (ruff I001)
- Install pandas-stubs for mypy type checking
- Add garbage collection cleanup to repository test fixtures
- Prevent Windows file locking errors in tempfile cleanup
All CI checks now passing: lint, type check, and all 244 tests.
- Use X | None syntax instead of Optional[X] (UP045)
- Sort imports in dashboard app (I001)
- Remove unnecessary UTF-8 encoding argument (UP012)
- Add 'from err' to exception re-raises (B904)
- Remove unused imports in integration tests (F401)
- Fix useless expression in test (B018)
- Cast **1.5 result to float in LDO model (mypy no-any-return)
- Use functools.partial instead of lambda in server (mypy misc)
InstrumentServer is a general-purpose SCPI-over-TCP server that can
host any device implementing the SCPIDevice protocol (process method).
Moving it from simulation/ to instruments/transport/ reflects this:
- simulation package now depends on instruments package
- InstrumentServer can host both virtual and real instrument adapters
- Added SCPIDevice Protocol for type-safe device registration
