- Add ROM tests when modifying editors
- Add AI tests when touching agent features
See `docs/internal/CI-TEST-STRATEGY.md` for detailed CI configuration.
For detailed CI configuration, see the CI/CD section below.

## Fast Test Builds (Recommended for Development)
For rapid test iteration, use the dedicated fast test presets. These use `RelWithDebInfo` with optimized flags (`-O2 -g1`) which builds **2-3x faster** than Debug while retaining enough debug info for test failures.
### Quick Commands (macOS)
```bash
# Configure with fast test preset
cmake --preset mac-test
# Build tests
cmake --build --preset mac-test
# Run stable tests with fast preset
ctest --preset fast
```
### Platform-Specific Fast Test Presets
| Platform | Configure Preset | Build Preset | Test Preset |
|----------|-----------------|--------------|-------------|
| macOS | `mac-test` | `mac-test` | `fast` |
| Windows | `win-test` | `win-test` | `fast-win` |
| Linux | `lin-test` | `lin-test` | `fast-lin` |
### Example Workflow
```bash
# One-liner: Configure, build, and test (macOS)
cmake --preset mac-test && cmake --build --preset mac-test && ctest --preset fast
# Windows equivalent
cmake --preset win-test && cmake --build --preset win-test && ctest --preset fast-win
# Linux equivalent
cmake --preset lin-test && cmake --build --preset lin-test && ctest --preset fast-lin
```
### z3ed CLI Self-Test
The z3ed CLI includes a built-in self-test for quick verification:
```bash
# Run z3ed self-test diagnostics
./build_test/bin/z3ed --self-test
# The self-test is also included in ctest with label "z3ed"

## ROM Auto-Discovery
The test framework automatically discovers ROMs without requiring environment variables. It searches for common ROM filenames in these locations (relative to working directory):
**Search Paths:** `.`, `roms/`, `../roms/`, `../../roms/`
**ROM Filenames:** `zelda3.sfc`, `alttp_vanilla.sfc`, `vanilla.sfc`, `Legend of Zelda, The - A Link to the Past (USA).sfc`
This means you can simply place your ROM in the `roms/` directory and run tests without setting `YAZE_TEST_ROM_PATH`:
```bash
# Just works if you have roms/zelda3.sfc
./build/bin/Debug/yaze_test_stable
```
The environment variable still takes precedence if set.
