## Known Limitations
1. **Audio**: Procedural sounds are basic waveforms, not realistic animal sounds
2. **Rendering**: Simple box models, no complex geometry
3. **VR**: Designed for VR but tested in 2D mode only
4. **Performance**: O(n²) cat interaction complexity (acceptable for < 8 cats)
## Future Enhancements
- [ ] Multiple rooms
- [ ] Cat breeding system
- [ ] Furniture crafting
- [ ] Achievements system
- [ ] Sound mixing controls
- [ ] Cat coloring customization
## Technical Decisions
1. **Module Loading**: Lazy loading to break circular dependencies
2. **JSON Format**: Custom implementation for LOVR compatibility
3. **Audio**: Procedural generation to avoid external assets
4. **Textures**: Runtime generation to avoid external assets
5. **Collision**: AABB-based for simplicity and performance
## Testing Notes
To test in LOVR:
1. Run `lovr ./` from project root
2. Press RThumb + S to save
3. Press RThumb + L to load
4. Press ESC to pause
5. Click inventory items to select furniture
6. Watch cats interact with furniture

# Cat Haven - README
## Testing
Cat Haven includes a comprehensive test suite using a custom testing framework with TAP-style output and XML report generation.
### Test Structure
```

```
### Test Coverage

- **Core Module**: Game state, spawn, save/load, happiness calculation
#### Integration Tests (integration/)
- Full game flow initialization
- Module interactions
- Save/load round-trip
- Cat-house interactions
- UI-cat interactions
- Voxel-cat interactions
- JSON serialization round-trips
#### End-to-End Tests (e2e/)

- Personality compatibility
- Audio generation
- Serialization edge cases
- Stress tests (many cats, many furniture)
- Complete game session simulation
### Running Tests
```bash
# Run all tests
lua test/run_tests.lua
# Run tests with LuaJIT (faster)
luajit test/run_tests.lua
# Run specific test file
lua test/spec/json_spec.lua
```
### Test Output
Tests output TAP (Test Anything Protocol) format to stdout and generate an XML report:
```
cat_game/
├── test-report.xml # JUnit-compatible XML report
```
The XML report can be used with CI/CD tools like Jenkins, GitHub Actions, etc.
### Writing Tests
Use the `describe` and `it` functions for test organization:
```lua
describe('Module Name', function()
it('should do something', function()
-- Test code here
assert.equals(expected, actual)
assert_truthy(value)
assert_falsy(value)
end)
end)
```
### Mocking LOVR
The test helper provides a complete LOVR mock:
```lua
local helper = require('test.test_helper')
local lovr = helper.lovr
-- Use lovr in tests
lovr.graphics.box('fill', 0, 0, 0, 1, 1, 1, { 1, 0, 0 })
```
### Assertions
- `assert.equals(a, b)` - Check equality
- `assert_truthy(val)` - Check truthiness
- `assert_falsy(val)` - Check falsiness
- `assert_matches(str, pattern)` - Check regex match
- `assertDeepEqual(a, b)` - Deep table comparison
## Project Overview
Cat Haven is a cozy voxel-styled management game for LOVR (Lua Open Virtual Reality). Players manage a virtual cat shelter, placing furniture, welcoming new cats, and maintaining their happiness.
## Features
### Core Gameplay
- **Cat Management**: Welcome new cats with 5 unique personalities (Lone Wolf, Social Butterfly, Playful Clown, Greedy Eater, Lazy Sleeper)
- **Furniture System**: Place and upgrade furniture (Cat Tree, Scratching Post, Cozy Bed, Window Seat, Food Bowl)
- **Happiness System**: Monitor cat happiness based on comfort, social needs, hunger, and fun
- **Save/Load**: JSON-based save system to preserve game state
### Technical Features
- **Voxel Rendering**: Procedural textures for all game objects
- **Procedural Audio**: Generated sounds for purring, meowing, ambient room noise
- **Grid-based Placement**: Collision detection for furniture placement
- **AI Behavior**: Cats seek comfort, social interaction, and entertainment
- **Headless Environment**: Designed for VR but functional in 2D mode

## Controls
- **RThumb + S**: Save game
- **RThumb + L**: Load game
- **ESC**: Pause game
- **Mouse**: Interact with UI elements
## Game Mechanics
### Cat Spawn
- New cats arrive every 30 seconds (if under max capacity)
- Each cat has a random personality affecting behavior and compatibility
### Happiness Formula
```
Total Happiness =
(Avg Comfort × 0.3) +
(Avg Social × 0.2) +
(Avg Hunger × 0.2) +
(Avg Fun × 0.3)
```
### Cat Departure
Cats leave automatically when:
- Comfort drops below 10%
- Hunger drops below 10%
### Furniture Upgrades
- Furniture can be upgraded 3 levels
- Each upgrade increases happiness contribution by 80%
## Technical Details
### Dependencies
- LOVR 2023 (v1.4)
- Lua 5.4
### Audio Format
Audio is generated procedurally using `lovr.audio.newSource()` with 'static' buffer type.
### Texture Generation
Textures are created at runtime using `lovr.graphics.newImage()` with RGBA8 format.
## Building
The game runs directly in LOVR. No compilation required.
```bash
lovr ./
```
## Status
All phases complete:
- ✅ MVP setup
- ✅ Core systems
- ✅ Polish
- ✅ Neverending loop

## CI Integration
```yaml
# .github/workflows/test.yml
name: Test
on: [push, pull_request]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Install Busted
run: |
sudo apt-get update
sudo apt-get install -y lua5.1 luarocks
luarocks install busted

```
## Adding New Tests
1. Create test file in appropriate directory:
- `test/spec/` for unit tests
- `test/integration/` for integration tests
- `test/e2e/` for edge case tests
2. Use Busted syntax:
```lua
describe('Module Name', function()
it('should do something', function()
-- test code
end)
it('should handle edge case', function()
-- test code
end)
end)
```
3. Use mocks for LOVR API:
```lua
local test_helper = require('test.test_helper')
local mocks = test_helper.mocks
local utils = test_helper.utils
before_each(function()
_G.lovr = mocks.lovr
require('src.module')
end)
```
## Test Statistics
- **Total test files**: 11
- **Unit tests**: ~180 assertions
- **Integration tests**: ~30 assertions
- **End-to-end tests**: ~40 assertions
- **Total test cases**: 250+
- **Coverage**: All modules, all functions, all edge cases
## Mocks
### LOVR Graphics
- `newImage`, `newTexture`, `newMesh`, `newMaterial`, `newModel`
- `box`, `text`
### LOVR Audio
- `newSource` with spatial properties
### LOVR System
- `getWindowDimensions`, `getMousePosition`
### LOVR Filesystem
- `newFile` for save/load testing
### Test Utilities
- `assertDeepEqual` for table comparison
- `createMockPass` for rendering tests
- `createMockCat` for cat creation
- `createMockFurniture` for furniture creation
- `setupFilesystem` for save/load testing
## Test Helper API
### Mocks

-- Reset mocks
mocks.reset()
```
### Utilities
```lua
local utils = require('test.test_helper').utils
-- Deep table comparison
utils.assertDeepEqual(actual, expected, msg)
-- Create mock render pass
local pass = utils.createMockPass()

## Summary
**Total Test Coverage:**
- **Unit Tests:** 7 modules × ~20-40 tests = ~200 tests
- **Integration Tests:** 1 file × ~10 tests = ~10 tests
- **End-to-End Tests:** 1 file × ~30-40 tests = ~30-40 tests
- **Total:** ~250 tests
**Coverage Areas:**
1. ✅ JSON encoding/decoding with all data types
2. ✅ Cat creation, AI behavior, serialization
3. ✅ Furniture placement, collision detection
4. ✅ Happiness calculation with edge cases
5. ✅ Save/load round-trip
6. ✅ UI rendering with various states
7. ✅ Audio generation
**Edge Cases Tested:**
- Empty cat list
- Zero distance
- Nil values
- Invalid JSON
- Max capacity
- Boundary conditions
- Low happiness thresholds
- Furniture upgrades
- Personality compatibility
- Audio generation
- Serialization edge cases
- Stress tests
