### All KiCad-Critical Features Tested

All previously untested features have now been implemented and tested:

| Feature | KiCad Usage | Priority | Status |
|---------|-------------|----------|--------|
| wxDataViewCtrl virtual mode | Zone Manager, Net Inspector (large data) | HIGH | ✓ TESTED |
| wxAuiNotebook | Tab panels (variant) | MEDIUM | ✓ TESTED |
| wxWizard | Footprint wizard | MEDIUM | ✓ TESTED |
| wxGrid cell editing | Property editing | MEDIUM | ✓ TESTED |
| wxCalendarCtrl | Date selection | LOW | ✓ TESTED |
| wxGrid custom renderers | Layer manager color swatches | HIGH | ✓ TESTED |

| wxCheckListBox | Layer visibility toggles | MEDIUM | ✓ TESTED |

**Current Coverage**: ~100% of KiCad-critical features tested (244 tests across 38 apps)

### Not Needed for KiCad
1. wxRichTextCtrl - Disabled in WASM build, KiCad doesn't use it
2. wxGraphicsContext - KiCad uses OpenGL GAL directly, not wxGraphicsContext

---

## WASM Implementation Limitations

Some wxWidgets features have incomplete WASM implementations. These are documented below with their current status.

### Known WASM Limitations

| Feature | Status | Details |
|---------|--------|---------|
| wxGraphicsContext | NOT NEEDED | KiCad uses OpenGL GAL directly (via WebGL in WASM) |
| Threading (wxThread) | STUBBED | WASM is single-threaded, API exists but no-op |
| wxFileName::GetSize | STUBBED | Returns wxInvalidSize for virtual filesystem |

### Recently Implemented WASM Features

These features were implemented to improve KiCad compatibility:

| Feature | Status | Implementation Notes |
|---------|--------|----------------------|
| wxFontEnumerator | WORKS | Uses Local Font Access API (Chrome 103+) with Asyncify |
| Bitmap masking | WORKS | wxMask with color-keyed transparency via Canvas composite ops |
| Text decorations | WORKS | Underline/strikethrough via Canvas textDecoration property |
| Non-rectangular regions | WORKS | wxRegion clipping via Canvas path-based clip() with multiple rects |

### WASM Edge Cases Tested

The `wasmedge_test` app verifies WASM-specific behaviors:

- **File System**: `/tmp/` virtual filesystem read/write works
- **Threading**: wxUSE_THREADS defined but stubbed (expected)
- **Font Enumeration**: Works via Local Font Access API (Chrome 103+)
- **Clipboard**: Works via Asyncify browser integration
- **Memory Growth**: WASM memory growth works (10MB+ allocations)
- **OS Info**: wxGetOsVersion returns stubbed values (expected)
- **URL Launch**: wxLaunchDefaultBrowser works via window.open()
- **wxFileName**: Path manipulation functions work correctly

---

## Build Notes

### GL vs Non-GL Apps
- Main app (minimal_test) uses `LDFLAGS_GL` with OpenGL support
- Standalone test apps use `LDFLAGS_NOGL` without OpenGL
- This prevents "_glBegin is not defined" crashes in non-GL apps

### Build Command
Always use the build script:
```bash
cd tests/wasm-app && ./build-test-apps.sh
```

---

## Baseline Screenshots

The test suite captures screenshots during test runs for visual regression testing. These screenshots are compared against a baseline to detect unexpected visual changes.

### Directory Structure

```
tests/
├── baseline-screenshots/     # Known-good reference screenshots (146+ files)
├── test-results/            # Screenshots from latest test run
└── wasm-app/
    └── e2e/                 # Playwright test specs
```

### Comparing Screenshots

Use the comparison script to check for visual regressions:

```bash
./scripts/compare-screenshots.sh
```

This will:
- Compare all baseline screenshots with current test results
- Report identical, different, and missing screenshots
- Show file size differences (useful for detecting changes)

Example output:
```
=== Screenshot Comparison ===
Baseline:     /path/to/tests/baseline-screenshots
Test Results: /path/to/tests/test-results

=== Comparing Baseline Screenshots ===
DIFFERENT: dialogs-msgbox-info-open.png (baseline: 47468B, current: 47478B, diff: 10B / .02%)

=== Summary ===
Total baseline screenshots: 121
Identical:                  54
Different:                  67
Missing from test results:  0
```

### Understanding Differences

Small byte differences (<2%) are typically caused by:
- **Timestamps** in event logs (e.g., `[19:45:35]` vs `[18:49:35]`)
- **PNG compression** variations between runs
- **Anti-aliasing** differences

These are **not** visual regressions. Visually inspect screenshots if you see larger differences.

### Updating Baseline Screenshots

After verifying changes are intentional, update the baseline:

```bash
# Copy current screenshots to baseline
cp tests/test-results/*.png tests/baseline-screenshots/

# Or selectively update specific screenshots
cp tests/test-results/dialog-*.png tests/baseline-screenshots/
```

### Running Tests with Screenshots

```bash
cd tests/wasm-app
npm test                    # Run all tests (saves screenshots to test-results/)
npx playwright test --ui    # Interactive mode with screenshot preview
```
