# FlexLove GUI Library Test Suite
This directory contains comprehensive tests for the FlexLove GUI library. The tests cover layout behavior, property management, animations, and utility functions.
## Test Files
1. **01_absolute_positioning.lua**
- Basic absolute positioning
- Parent-child relationships
- Coordinate system tests
2. **02_flex_direction.lua**
- Horizontal flex layout
- Vertical flex layout
- Mixed direction layouts
3. **03_vertical_flex_direction.lua**
- Vertical layout specifics
- Column-based layouts
- Vertical alignment
4. **04_justify_content.lua**
- Flex-start alignment
- Flex-end alignment
- Space-between distribution
- Space-around distribution
5. **05_align_items.lua**
- Cross-axis alignment
- Stretch behavior
- Baseline alignment
6. **06_flex_wrap.lua**
- Wrapping behavior
- Multi-line layouts
- Wrap alignment
7. **07_layout_validation.lua**
- Edge cases
- Nested containers
- Deep hierarchies
8. **08_performance.lua**
- Large element counts
- Deep hierarchies
- Dynamic updates
- Rapid resizing
9. **09_element_properties.lua**
- Basic properties
- Custom properties
- Property modification
- Visibility and clipping
10. **10_animation_and_transform.lua**
- Basic transformations
- Animation tweening
- Easing functions
- Animation cancellation
11. **11_auxiliary_functions.lua**
- Element queries
- Debug utilities
- Layout helpers
- Utility functions
## Running Tests
### Run All Tests
```bash
cd /path/to/station_alpha
for f in game/libs/testing/__tests__/flexlove/*.lua; do lua "$f"; done
```
### Run Specific Test File
```bash
cd /path/to/station_alpha
lua game/libs/testing/__tests__/flexlove/[test_file].lua
```
## Test Structure
Each test file follows this general structure:
```lua
package.path = package.path .. ";/path/to/station_alpha/?.lua"
local luaunit = require('game/libs/testing/luaunit')
require('game/libs/testing/loveStub')
local FlexLove = require('game/libs/FlexLove')
TestClassName = {}
function TestClassName:setUp()
self.GUI = FlexLove.GUI
end
function TestClassName:testFeature()
-- Test implementation
end
os.exit(luaunit.LuaUnit.run())
```
## Known Issues
1. Layout Calculations
- Some justify-content calculations need verification
- Align-items behavior needs adjustment
- Flex-wrap positioning requires fixes
2. Missing Methods
- Animation and transform methods not implemented
- Some utility functions not available
- Custom property support incomplete
3. Performance
- Resize calculations may need optimization
- Deep hierarchy performance could be improved
## Contributing
When adding new tests:
1. Follow the existing naming convention
2. Add proper type annotations
3. Include nil checks for optional features
4. Document expected behavior
5. Add the test to this README
## Dependencies
- Lua 5.1+ / LuaJIT
- LÖVE2D (for graphics features)
- luaunit (testing framework)
