## Testing Game Changes
|
||||
## Testing
|
||||
|
||||
Currently no automated test suite. Manual testing workflow:
|
||||
1. Build with `make`
|
||||
2. Run `make run` or `cd build && ./mcrogueface`
|
||||
3. Test specific features through gameplay
|
||||
4. Check console output for Python errors
|
||||
### Test Suite Structure
|
||||
|
||||
The `tests/` directory contains the comprehensive test suite:
|
||||
|
||||
```
|
||||
tests/
|
||||
├── run_tests.py # Test runner - executes all tests with timeout
|
||||
├── unit/ # Unit tests for individual components (105+ tests)
|
||||
├── integration/ # Integration tests for system interactions
|
||||
├── regression/ # Bug regression tests (issue_XX_*.py)
|
||||
├── benchmarks/ # Performance benchmarks
|
||||
├── demo/ # Feature demonstration system
|
||||
│ ├── demo_main.py # Interactive demo runner
|
||||
│ ├── screens/ # Per-feature demo screens
|
||||
│ └── screenshots/ # Generated demo screenshots
|
||||
└── notes/ # Analysis files and documentation
|
||||
```
|
||||
|
||||
### Running Tests
|
||||
|
||||
```bash
|
||||
# Run the full test suite (from tests/ directory)
|
||||
cd tests && python3 run_tests.py
|
||||
|
||||
# Run a specific test
|
||||
cd build && ./mcrogueface --headless --exec ../tests/unit/some_test.py
|
||||
|
||||
# Run the demo system interactively
|
||||
cd build && ./mcrogueface ../tests/demo/demo_main.py
|
||||
|
||||
# Generate demo screenshots (headless)
|
||||
cd build && ./mcrogueface --headless --exec ../tests/demo/demo_main.py
|
||||
```
|
||||
|
||||
### Reading Tests as Examples
|
||||
|
||||
**IMPORTANT**: Before implementing a feature or fixing a bug, check existing tests for API usage examples:
|
||||
|
||||
- `tests/unit/` - Shows correct usage of individual mcrfpy classes and functions
|
||||
- `tests/demo/screens/` - Complete working examples of UI components
|
||||
- `tests/regression/` - Documents edge cases and bug scenarios
|
||||
|
||||
Example: To understand Animation API:
|
||||
```bash
|
||||
grep -r "Animation" tests/unit/
|
||||
cat tests/demo/screens/animation_demo.py
|
||||
```
|
||||
|
||||
### Writing Tests
|
||||
|
||||
**Always write tests when adding features or fixing bugs:**
|
||||
|
||||
1. **For new features**: Create `tests/unit/feature_name_test.py`
|
||||
2. **For bug fixes**: Create `tests/regression/issue_XX_description_test.py`
|
||||
3. **For demos**: Add to `tests/demo/screens/` if it showcases a feature
|
||||
|
||||
### Quick Testing Commands
|
||||
```bash
|
||||
# Test basic functionality
|
||||
make test
|
||||
|
||||
# Run in Python interactive mode
|
||||
make python
|
||||
|
||||
# Test headless mode
|
||||
# Test headless mode with inline Python
|
||||
cd build
|
||||
./mcrogueface --headless -c "import mcrfpy; print('Headless test')"
|
||||
|
||||
# Run specific test with output
|
||||
./mcrogueface --headless --exec ../tests/unit/my_test.py 2>&1
|
||||
```

## Testing Guidelines
|
||||
|
||||
### Test-Driven Development
|
||||
- **Always write tests first**: Create automation tests in `./tests/` for all bugs and new features
|
||||
- **Practice TDD**: Write tests that fail to demonstrate the issue, then pass after the fix is applied
|
||||
- **Close the loop**: Reproduce issue → change code → recompile → verify behavior change
|
||||
- **Always write tests first**: Create tests in `./tests/` for all bugs and new features
|
||||
- **Practice TDD**: Write tests that fail to demonstrate the issue, then pass after the fix
|
||||
- **Read existing tests**: Check `tests/unit/` and `tests/demo/screens/` for API examples before writing code
|
||||
- **Close the loop**: Reproduce issue → change code → recompile → run test → verify
|
||||
|
||||
### Two Types of Tests
|
||||
|
||||
#### 1. Direct Execution Tests (No Game Loop)
|
||||
For tests that only need class initialization or direct code execution:
|
||||
```python
|
||||
# These tests can treat McRogueFace like a Python interpreter
|
||||
# tests/unit/my_feature_test.py
|
||||
import mcrfpy
|
||||
import sys
|
||||
|
||||
# Test code here
|
||||
result = mcrfpy.some_function()
|
||||
assert result == expected_value
|
||||
print("PASS" if condition else "FAIL")
|
||||
# Test code - runs immediately
|
||||
frame = mcrfpy.Frame(pos=(0,0), size=(100,100))
|
||||
assert frame.x == 0
|
||||
assert frame.w == 100
|
||||
|
||||
print("PASS")
|
||||
sys.exit(0)
|
||||
```
|
||||
|
||||
#### 2. Game Loop Tests (Timer-Based)
|
||||
For tests requiring rendering, game state, or elapsed time:
|
||||
For tests requiring rendering, screenshots, or elapsed time:
|
||||
```python
|
||||
# tests/unit/my_visual_test.py
|
||||
import mcrfpy
|
||||
from mcrfpy import automation
|
||||
import sys
|
||||
|
||||
def run_test(runtime):
|
||||
"""Timer callback - runs after game loop starts"""
|
||||
# Now rendering is active, screenshots will work
|
||||
automation.screenshot("test_result.png")
|
||||
|
||||
# Run your tests here
|
||||
automation.click(100, 100)
|
||||
|
||||
# Always exit at the end
|
||||
print("PASS" if success else "FAIL")
|
||||
# Validate results...
|
||||
print("PASS")
|
||||
sys.exit(0)
|
||||
|
||||
# Set up the test scene
|
||||
mcrfpy.createScene("test")
|
||||
# ... add UI elements ...
|
||||
|
||||
# Schedule test to run after game loop starts
|
||||
mcrfpy.setTimer("test", run_test, 100) # 0.1 seconds
|
||||
ui = mcrfpy.sceneUI("test")
|
||||
ui.append(mcrfpy.Frame(pos=(50,50), size=(100,100)))
|
||||
mcrfpy.setScene("test")
|
||||
mcrfpy.setTimer("test", run_test, 100)
|
||||
```
|
||||
|
||||
### Key Testing Principles
|
||||
- **Timer callbacks are essential**: Screenshots and UI interactions only work after the render loop starts
|
||||
- **Use automation API**: Always create and examine screenshots when visual feedback is required
|
||||
- **Exit properly**: Call `sys.exit()` at the end of timer-based tests to prevent hanging
|
||||
- **Headless mode**: Use `--exec` flag for automated testing: `./mcrogueface --headless --exec tests/my_test.py`
|
||||
- **Timer callbacks are essential**: Screenshots only work after the render loop starts
|
||||
- **Use automation API**: `automation.screenshot()`, `automation.click()` for visual testing
|
||||
- **Exit properly**: Always call `sys.exit(0)` for PASS or `sys.exit(1)` for FAIL
|
||||
- **Headless mode**: Use `--headless --exec` for CI/automated testing
|
||||
- **Check examples first**: Read `tests/demo/screens/*.py` for correct API usage
|
||||
|
||||
### Example Test Pattern
|
||||
```bash
|
||||
# Run a test that requires game loop
|
||||
./build/mcrogueface --headless --exec tests/issue_78_middle_click_test.py
|
||||
### API Quick Reference (from tests)
|
||||
```python
|
||||
# Animation: (property, target_value, duration, easing)
|
||||
anim = mcrfpy.Animation("x", 500.0, 2.0, "easeInOut")
|
||||
anim.start(frame)
|
||||
|
||||
# The test will:
|
||||
# 1. Set up the scene during script execution
|
||||
# 2. Register a timer callback
|
||||
# 3. Game loop starts
|
||||
# 4. Timer fires after 100ms
|
||||
# 5. Test runs with full rendering available
|
||||
# 6. Test takes screenshots and validates behavior
|
||||
# 7. Test calls sys.exit() to terminate
|
||||
# Caption: use keyword arguments to avoid positional conflicts
|
||||
cap = mcrfpy.Caption(text="Hello", pos=(100, 100))
|
||||
|
||||
# Grid center: uses pixel coordinates, not cell coordinates
|
||||
grid = mcrfpy.Grid(grid_size=(15, 10), pos=(50, 50), size=(400, 300))
|
||||
grid.center = (120, 80) # pixels: (cells * cell_size / 2)
|
||||
|
||||
# Keyboard handler: key names are "Num1", "Num2", "Escape", "Q", etc.
|
||||
def on_key(key, state):
|
||||
if key == "Num1" and state == "start":
|
||||
mcrfpy.setScene("demo_1")
|
||||
```
|
||||
|
||||
## Development Best Practices
|
||||
|
||||
### Testing and Deployment
|
||||
- **Keep tests in ./tests, not ./build/tests** - ./build gets shipped, and tests shouldn't be included
|
||||
- **Keep tests in ./tests, not ./build/tests** - ./build gets shipped, tests shouldn't be included
|
||||
- **Run full suite before commits**: `cd tests && python3 run_tests.py`
