### 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 |
| wxPrintPreview frame | Schematic/PCB print preview | MEDIUM | ✓ TESTED |
| wxBitmapButton | Toolbar icons | MEDIUM | ✓ TESTED |
| wxTreebook | Settings dialogs (hierarchical) | MEDIUM | ✓ TESTED |
| wxBitmapComboBox | Layer chooser with swatches | MEDIUM | ✓ 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
- All wx test apps (including minimal_test) link with `LDFLAGS_NOGL`; legacy GL
  emulation was removed 2026-06-10. WebGL rendering is tested by gal-webgl.

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

---

## Baseline Screenshots

The test suite captures raw PNGs during test runs for visual regression testing,
compared offline against per-engine baselines (the calibrated gate in
`tools/screenshots/`). Baseline PNGs live in the private R2 bucket
`pcbjam-ci-screenshots` (content-addressed by sha256); git commits only the
manifest that pins them.

### Directory Structure

```
tests/
├── baseline-screenshots/    # GITIGNORED cache of the R2 bucket (npm run screenshots:fetch)
│   ├── chromium/            # Known-good references, Chromium render
│   └── firefox/             # Known-good references, Firefox render
├── test-results/
│   ├── chromium/            # Latest run's captures per engine
│   └── firefox/
└── screenshot-manifest.json  # Committed pin: {name, engine, sha256, …} per baseline
```

Specs write via `stableShot(page, 'name.png')` / `shotPath(page, 'name.png')`
(`e2e/utils/element-tracker.ts`) — the engine subdir is derived from the running
browser, so the same spec on two engines produces two independent captures.

### Comparing Screenshots

```bash
cd tests
npm run screenshots:fetch   # materialize the baseline cache from R2 (idempotent)
npm run screenshots:check
```

This diffs `test-results/<engine>/` against `baseline-screenshots/<engine>/` with
per-engine calibrated noise floors and reports CHANGED / ADDED / REMOVED (removed
detection is driven by the manifest). On each main push, CI posts the same report
(triptych images labeled `[chromium]`/`[firefox]`) to Discord.

### Updating Baseline Screenshots

CI's Linux render is the source of truth — never copy local (Mac) renders into
the baselines. Promote from a CI run instead (churn-free: only meaningfully
changed images restage, and the manifest regenerates automatically):

```bash
cd tests
npm run screenshots:promote -- --run <ci-run-id>   # needs the read-write R2 keypair (tests/.env)
git commit   # only screenshot-manifest.json changes — PNGs are uploaded to R2, never committed
```

### Running Tests with Screenshots

```bash
cd tests
npm test                    # setup + the full merged run (all CI projects)
npx playwright test --ui    # Interactive mode with screenshot preview
```
