Implements Phase 1 of TESTING_STRATEGY_PHASE5.md with comprehensive integration tests covering compile → runtime → inspector synchronization. Tests Added (all passing): - Compile/runtime/inspector roundtrip (basic + multiple properties) - Property get/set operations (existing and nonexistent) - Type conversion behavior (Float→Int) - Range validation and clamping - Immutability enforcement (compiler rejects @export on let) - Hot-reload scenarios (add/remove properties) - Performance stress tests (50 properties, 1000 rapid accesses) - from_inspector parameter correctness - Property access before execution Key Findings Documented: 1. ✅ Compiler correctly rejects @export on immutable (E812) 2.⚠️ Runtime allows type mismatches without validation - set_exported_property accepts any Value type - Could cause runtime errors later - TODO: Consider adding type checking 3.⚠️ Properties persist after hot-reload - exported_properties HashMap not cleared on recompilation - Removed properties still accessible - May be intentional for Inspector value preservation - TODO: Document hot-reload semantics Test Coverage: - Integration: 15 new tests (0 → 15) - Total project: 717 tests passing (702 + 15) - 0 failures, 10 ignored (Godot engine tests) Impact: - Closes critical integration testing gap - Documents actual runtime behavior vs expected - Identifies 2 areas for potential improvement - Provides regression protection for Phase 5 features See: docs/planning/v0.0.4/TESTING_STRATEGY_PHASE5.md
Documents implementation of 15 critical integration tests covering end-to-end Inspector synchronization (compile → runtime → inspector). Report Contents: - Executive summary with key metrics (717 total tests passing) - Detailed breakdown of 9 test categories - Key findings: 5 strengths, 2 areas for improvement - Type safety analysis (runtime doesn't validate types) - Hot-reload behavior documentation (properties persist) - Impact on testing strategy (Phase 1 complete) - Next steps and recommendations Key Insights: ✅ Compiler correctly rejects @export on immutable (E812) ✅ Complete integration chain working correctly ✅ Performance excellent (50 properties, 1000 accesses)⚠️ Runtime accepts any type in set_exported_property (no validation)⚠️ Properties persist in HashMap after hot-reload removes them Recommendations: 1. Add type validation in set_exported_property (2-3 hours) 2. Clarify hot-reload semantics (intentional vs bug) 3. Consider auto-pruning removed properties (1-2 hours) Testing Coverage: - Phase 1 (Integration Tests): ✅ COMPLETE - Phase 2 (Headless Godot): Next priority - Phase 3-5: Scheduled per testing strategy See: docs/planning/v0.0.4/INTEGRATION_TESTS_REPORT.md

… existing infrastructure
**PROBLEM**: Duplicated testing infrastructure and unclear testing patterns
**ROOT CAUSE**:
- Created new headless testing infrastructure without discovering existing test_harness
- test_harness + ferris-test.toml already handle Godot headless execution
- Documentation spread across multiple files without clear SSOT
**SOLUTION**: Refactor to use existing infrastructure + create TESTING_GUIDE.md
**Changes**:
1. **Created TESTING_GUIDE.md** (1000+ lines) - Single Source of Truth
- Documents all 4 testing patterns (Unit, Integration, GDExtension, Benchmark)
- Clear layer separation and when to use each
- Configuration guide (ferris-test.toml)
- Running tests commands
- Troubleshooting section
- Explains why 10 godot_bind tests are ignored (covered by integration tests)
2. **Refactored headless_integration.rs** to use existing infrastructure:
- BEFORE: Custom get_godot_exe() reading GODOT_BIN env var
- AFTER: Uses TestConfig::from_file('ferris-test.toml')
- Applies environment overrides via config.with_env_overrides()
- Uses existing GodotRunner from test_harness
- Eliminates duplicate configuration logic
3. **Updated documentation** to reference TESTING_GUIDE.md:
- HEADLESS_GODOT_SETUP.md: Marked as archival, points to TESTING_GUIDE.md
- RUNNING_HEADLESS_TESTS.md: Marked as archival, content in TESTING_GUIDE.md
- TESTING_STRATEGY_PHASE5.md: Added reference to TESTING_GUIDE.md as primary doc
**Test Coverage Clarification**:
- 702 unit tests (compiler, runtime, godot_bind, test_harness)
- 15+ integration tests (.ferris scripts)
- 10 ignored godot_bind tests → Covered by integration tests (export_properties_test.ferris)
- GDExtension testing pattern documented for future use
**Benefits**:
- ✅ Single source of truth for all testing patterns
- ✅ Discoverable testing documentation (TESTING_GUIDE.md)
- ✅ Eliminates duplicate configuration (uses ferris-test.toml)
- ✅ Generalizable pattern for any crate needing GDExtension tests
- ✅ Clear explanation of why some tests are ignored
**See**: docs/TESTING_GUIDE.md for complete testing reference

…erability
**Problem**: Testing infrastructure wasn't discoverable, leading to:
- Copilot suggesting duplicate test framework creation
- Contributors unaware of existing ferris-test harness
- No central hub for test documentation
- Test matrices not linked or tracked systematically
**Solution**: Create docs/testing/README.md as single source of truth
**Changes**:
1. **docs/testing/README.md** (NEW):
- Central hub for all testing documentation (500+ lines)
- 4-layer testing strategy overview
- Quick-start guides for each test type:
* Unit (compiler): 543 tests
* Unit (runtime): 110 tests
* Integration (.ferris): 15+ tests
* Headless (GDExtension): 11 pass, 10 ignored
* Benchmarks: 8 suites
- Test matrix tracking section with coverage summary
- ferris-test CLI documentation
- Testing checklist for new features
- Backlinks to TESTING_GUIDE, DEVELOPMENT, CONTRIBUTING
2. **docs/DEVELOPMENT.md**:
- Updated "Test Your Changes" section
- Added link to testing/README.md
- Expanded testing layer explanation
- Added quick links to testing docs
3. **CONTRIBUTING.md**:
- Updated "Testing Guidelines" section
- Added 4-layer testing strategy overview
- Linked to testing/README.md and TESTING_GUIDE.md
- Updated ferris-test documentation
- Emphasized testing requirements
**Impact**:
- ✅ Testing infrastructure now highly discoverable
- ✅ Clear entry point (testing/README.md) for all testing
- ✅ Test matrices linked for systematic tracking
- ✅ Reduced risk of duplicate infrastructure creation
- ✅ Better contributor onboarding
**Related**: v0.0.4 Phase 5 completion, test harness maturity
