Refactor timing tests to use mcrfpy.step() for synchronous execution

Converts tests from Timer-based async patterns to step()-based sync
patterns, eliminating timeout issues in headless testing.

Refactored tests:
- simple_timer_screenshot_test.py
- test_animation_callback_simple.py
- test_animation_property_locking.py
- test_animation_raii.py
- test_animation_removal.py
- test_timer_callback.py

Also updates KNOWN_ISSUES.md with comprehensive documentation on
the step()-based testing pattern including examples and best practices.

@ -8,20 +8,94 @@ As of 2026-01-14, with `--mcrf-timeout=5`:
- 40 timeout failures (tests requiring timers/animations)
- 19 actual failures (API changes, missing features, or bugs)
## Timeout Failures (40 tests)
## Synchronous Testing with `mcrfpy.step()`
These tests require timers, animations, or callbacks that don't complete within the 5s timeout.
Run with `--mcrf-timeout=30` for a more permissive test run.
**RECOMMENDED:** Use `mcrfpy.step(t)` to advance simulation time synchronously instead of relying on Timer callbacks and the game loop. This eliminates timeout issues and makes tests deterministic.
**Animation/Timer tests:**
- WORKING_automation_test_example.py
- benchmark_logging_test.py
- keypress_scene_validation_test.py
### Old Pattern (Timer-based, async)
```python
# OLD: Requires game loop, subject to timeouts
def run_tests(timer, runtime):
# tests here
sys.exit(0)
mcrfpy.Timer("run", run_tests, 100, once=True)
# Script ends, game loop runs, timer eventually fires
```
### New Pattern (step-based, sync)
```python
# NEW: Synchronous, no timeouts
import mcrfpy
import sys
# Setup scene
scene = mcrfpy.Scene("test")
scene.activate()
mcrfpy.step(0.1) # Initialize scene
# Run tests directly
frame = mcrfpy.Frame(pos=(100, 100), size=(100, 100))
scene.children.append(frame)
# Start animation
anim = mcrfpy.Animation("x", 500.0, 1.0, "linear")
anim.start(frame)
# Advance simulation to complete animation
mcrfpy.step(1.5) # Advances 1.5 seconds synchronously
# Verify results
if frame.x == 500.0:
print("PASS")
sys.exit(0)
else:
print("FAIL")
sys.exit(1)
```
### Key Differences
| Aspect | Timer-based | step()-based |
|--------|-------------|--------------|
| Execution | Async (game loop) | Sync (immediate) |
| Timeout risk | High | None |
| Determinism | Variable | Consistent |
| Timer firing | Once per step() call | Per elapsed interval |
### Timer Behavior with `step()`
- Timers fire once per `step()` call if their interval has elapsed
- To fire a timer multiple times, call `step()` multiple times:
```python
# Timer fires every 100ms
timer = mcrfpy.Timer("tick", callback, 100)
# This fires the timer ~6 times
for i in range(6):
mcrfpy.step(0.1) # Each step processes timers once
```
## Refactored Tests
The following tests have been converted to use `mcrfpy.step()`:
- simple_timer_screenshot_test.py
- test_animation_callback_simple.py
- test_animation_property_locking.py
- test_animation_raii.py
- test_animation_removal.py
- test_timer_callback.py
- test_timer_once.py
## Remaining Timeout Failures
These tests still use Timer-based async patterns:
- WORKING_automation_test_example.py
- benchmark_logging_test.py
- keypress_scene_validation_test.py
- test_empty_animation_manager.py
- test_simple_callback.py
