+# Unit Test Coverage Summary
+
+## Overview
+This document summarizes the comprehensive unit tests generated for the new minimap feature implementation (branch: new_minimap vs dev).
+
+## Changed Files and Test Coverage
+
+### 1. src/map.c / src/map.h
+**Changes:**
+- Modified `map_set_current_room()` to include first_visit detection
+- Added `bool* first_visit` output parameter
+- Enhanced room tracking logic
+
+**Test File:** `test/test_map_room_tracking.c`
+
+**Test Cases (12 total):**
+1. **test_map_set_current_room_basic** - Basic room coordinate calculation from world position
+2. **test_map_set_current_room_first_visit_true** - Verify first_visit flag is true on initial entry
+3. **test_map_set_current_room_first_visit_false** - Verify first_visit flag is false on subsequent entries
+4. **test_map_set_current_room_null_first_visit** - NULL parameter safety (backward compatibility)
+5. **test_map_set_current_room_exact_boundary** - Position exactly at room boundary
+6. **test_map_set_current_room_negative_position** - Negative positions clamp to (0,0)
+7. **test_map_set_current_room_beyond_bounds** - Out-of-bounds positions clamp to max room coordinates
+8. **test_map_set_current_room_multiple_visits** - Sequential room visits and revisits
+9. **test_map_set_current_room_same_room_movement** - Movement within same room maintains visited state
+10. **test_map_set_current_room_coordinate_calculation** - Various position-to-room coordinate conversions
+11. **test_map_set_current_room_one_pixel_before_boundary** - Edge case: one pixel before room boundary
+12. **test_map_set_current_room_corner_rooms** - All four corner rooms at map boundaries
+
+**Coverage:**
+- ✅ Happy path: basic room tracking
+- ✅ Edge cases: boundaries, negative values, out-of-bounds
+- ✅ First visit detection (true/false states)
+- ✅ NULL parameter safety
+- ✅ Multiple room transitions
+- ✅ Coordinate clamping logic
+
+### 2. src/gui.c / src/gui.h
+**Changes:**
+- Replaced `miniMapFrame` sprite with `miniMap` texture-based sprite
+- Added `gui_update_minimap()` - Updates minimap with room data
+- Added `gui_reset()` - Clears minimap texture
+- Modified `gui_render_minimap()` - Renders pixel-based minimap with current room highlight
+
+**Test File:** `test/test_gui_minimap.c`
+
+**Test Cases (14 total):**
+1. **test_gui_reset_clears_minimap** - Reset operation clears minimap without destroying it
+2. **test_gui_update_minimap_null_safety** - No crashes with valid parameters
+3. **test_gui_update_minimap_empty_room** - Handle empty room with all NULL spaces
+4. **test_gui_update_minimap_lethal_spaces** - Render lethal spaces (pits, etc.) correctly
+5. **test_gui_update_minimap_mixed_tiles** - Handle various tile types (walls, doors, tiles, occupied)
+6. **test_gui_update_minimap_different_room_positions** - Update minimap for different room coordinates
+7. **test_gui_render_minimap_basic** - Basic rendering without crashes
+8. **test_gui_render_minimap_room_positions** - Render with various room positions
+9. **test_gui_minimap_update_render_cycle** - Complete update→render cycle simulation
+10. **test_gui_minimap_multiple_updates** - Multiple sequential updates to same minimap
+11. **test_gui_minimap_dimensions** - Verify correct sprite and texture dimensions
+12. **test_gui_reset_after_updates** - Reset clears state after multiple updates
+13. **test_gui_minimap_texture_access_type** - Verify texture is SDL_TEXTUREACCESS_TARGET
+14. **test_gui_minimap_position** - Verify correct sprite position (0, 4)
+
+**Coverage:**
+- ✅ Minimap initialization and creation
+- ✅ Update cycle with various room states
+- ✅ Rendering with different room positions
+- ✅ Reset functionality
+- ✅ Multiple update/render cycles
+- ✅ Texture properties (dimensions, access type)
+- ✅ Sprite properties (position, fixed flag)
+- ✅ Edge cases: empty rooms, lethal spaces, mixed tiles
+
+### 3. Other Changed Files
+**Files:** src/main.c, src/player.c, src/skill.c, src/input.c
+
+**Changes:**
+- Integration code (calling new minimap functions)
+- Minor include statement additions
+
+**Testing Strategy:**
+These files contain integration logic that connects the tested components. The comprehensive unit tests for map.c and gui.c cover the core functionality. Integration testing would be handled at a higher level.
+
+## Test Framework
+**Framework:** CMocka (existing project standard)
+**Setup:** SDL3 initialization for GUI tests
+**Build Integration:** Added to test/CMakeLists.txt
+
+## Running the Tests
+```bash
+# From build directory
+cmake ..
+make test_map_room_tracking
+make test_gui_minimap
+
+# Run tests
+./test/test_map_room_tracking
+./test/test_gui_minimap
+```
+
+## Test Statistics
+- **Total Test Cases:** 26
+- **Test Files Created:** 2
+- **Functions Tested:** 4 (map_set_current_room, gui_update_minimap, gui_reset, gui_render_minimap)
+- **Code Coverage Focus:** New and modified code paths
+- **Edge Cases Covered:** 15+
+- **Integration Points:** Multiple
+
+## Test Quality Measures
+1. **Setup/Teardown:** Proper SDL initialization and cleanup for GUI tests
+2. **Memory Management:** All allocated resources properly freed
+3. **Isolation:** Tests are independent and don't affect each other
+4. **Assertions:** Clear, specific assertions with meaningful checks
+5. **Naming:** Descriptive test names following project conventions
+6. **Documentation:** Comments explaining test purpose and expectations
+
+## Coverage Highlights
+
+### Boundary Testing
+- Negative positions
+- Out-of-bounds coordinates
+- Exact boundary positions
+- Corner cases
+
+### State Management
+- First visit vs. subsequent visits
+- Room transition sequences
+- Multiple updates to same state
+
+### Null Safety
+- NULL parameter handling
+- Backward compatibility with existing code
+
+### Integration Scenarios
+- Update→Render cycles
+- Reset→Update→Render flows
+- Multiple room transitions
+
+## Future Considerations
+1. Consider adding performance tests for minimap rendering with large room counts
+2. Integration tests for the complete game loop with minimap updates
+3. Visual regression tests for minimap appearance
+4. Load testing for rapid room transitions
+
+## Conclusion
+The test suite provides comprehensive coverage of the new minimap feature with:
+- ✅ 26 test cases covering all new/modified functions
+- ✅ Extensive edge case and boundary testing
+- ✅ Proper memory management and resource cleanup
+- ✅ Integration with existing CMocka test framework
+- ✅ Clear documentation and maintainable code
