Adds a complete CI workflow that builds WLED-MM firmware, runs it in QEMU ESP32 emulation, and validates the web UI using Playwright browser tests.

What this PR does

  • QEMU E2E workflow (.github/workflows/qemu-e2e-test.yml): Builds firmware with OpenETH networking, launches QEMU with port forwarding, verifies HTTP connectivity, then runs Playwright tests
  • WLED_QEMU build flag: Skips WiFi and ESP32 EMAC hardware initialization that QEMU can't emulate, uses OpenETH MAC driver instead
  • Vendored OpenETH MAC driver (lib/openeth_mac/): ESP-IDF v4.4.7 source for esp_eth_mac_new_openeth() since the pre-built Tasmota libethernet.a doesn't include it
  • Playwright E2E tests (e2e-tests/): Tests all main UI pages using correct WLED server routes (/, /settings, /settings/wifi, /liveview, etc.) and validates JSON API endpoints
  • JS console log capture (e2e-tests/fixtures.js): Shared Playwright fixture captures all browser console messages (log, warn, error, info, debug) and page errors per test, writes per-test log files to console-logs/, attaches them to the HTML report, and uploads as a separate js-console-logs CI artifact
  • Network connectivity checks: Verifies DHCP, IP assignment, and HTTP 200 before running browser tests
  • CI artifacts: Uploads QEMU logs, Playwright HTML report, and JS console logs for debugging

Server Routes Tested

The tests use WLED's compiled-in page routes (not filesystem paths):

  • / — Main UI (index page)
  • /settings, /settings/wifi, /settings/leds, /settings/ui, /settings/sync, /settings/time, /settings/sec, /settings/um, /settings/2D — Settings pages
  • /simple.htm, /welcome, /update, /liveview — Other pages
  • /json/info, /json/state — JSON API endpoints

Build Environment

  • New PlatformIO env: esp32_16MB_QEMU_debug (ethernet + OpenETH + WLED_QEMU flag)
  • Feature branch added to push trigger for testing
  • @playwright/test installed in CI before browser download
Original prompt

This section details on the original issue you should resolve

<issue_title>Verify basic operations in CI</issue_title>
<issue_description>Can we have a CI workflow that uses qemu to actually try running the application on a simulated esp32 and correct with playwright to navigate though the basic pages to confirm that every page loads without JavaScript errors?

We can then later extend with further playwright tests and confirmation of the JSON API

The default image creates a WiFi AP, however using an ethernet supported build might be more appropriate, but then qemu would also need to emulate that ethernet controller as well as the esp32 </issue_description>

Walkthrough

This PR implements a complete QEMU-based end-to-end testing infrastructure for WLED's ESP32 firmware. It adds helper scripts to set up and run QEMU, configures a QEMU-specific firmware build, guards WiFi/AP initialization and network access in the firmware with WLED_QEMU preprocessor branches, defines Playwright test suites for page load validation, and orchestrates everything via a GitHub Actions workflow that builds the firmware, launches QEMU, executes tests, and reports results.

Changes

QEMU E2E Testing Infrastructure

Layer / File(s) Summary
QEMU helper scripts: setup, runtime, and exception decoding
.github/scripts/setup-qemu.sh, .github/scripts/run-qemu.sh, .github/scripts/monitor-qemu.py
Three executable scripts enable QEMU environment management: setup installs QEMU with dependency checks, run creates a 16MB flash image and launches QEMU with port forwarding to localhost:8080, and monitor decodes ESP32 exceptions by extracting hex addresses and invoking addr2line.
Firmware PlatformIO QEMU build configuration
platformio.ini
env:esp32_16MB_QEMU_debug creates a QEMU-targeted 16MB debug build disabling OTA/serial protocols, enabling Ethernet/OpenETH modes, setting QEMU-specific compile flags, and customizing pin/feature configurations.
Firmware network adapter for QEMU tcpip_adapter
wled00/src/dependencies/network/Network.cpp
localIP(), subnetMask(), gatewayIP(), isConnected(), and isEthernet() add WLED_QEMU-guarded branches that query tcpip_adapter directly instead of the ETH object, enabling Ethernet access in QEMU's user-mode networking.
Firmware QEMU defaults: AP behavior and static IP
wled00/wled.h
apBehavior defaults to AP_BEHAVIOR_BUTTON_ONLY in QEMU mode, staticIP can be overridden via WLED_STATIC_IP_DEFAULT_1..4, and WLED_CONNECTED macro bases connectivity solely on ETH.localIP()[0] under QEMU.
Firmware application logic: WiFi/AP/connection guarding
wled00/wled.cpp
WiFi/AP initialization, Improv scanning, and connection handling are wrapped with #ifndef WLED_QEMU guards; initEthernet() adds a QEMU branch skipping ETH.begin() and manually configuring tcpip_adapter with DHCP or static IP.
Playwright test configuration and npm scripts
playwright.config.js, package.json
playwright.config.js configures sequential execution, HTML reporting, and baseURL from WLED_BASE_URL environment variable; package.json adds @playwright/test dependency and test:e2e, test:e2e:ui, and test:e2e:debug npm scripts.
Playwright E2E test suites
e2e-tests/index.spec.js, e2e-tests/settings.spec.js, e2e-tests/other-pages.spec.js
Three test spec files verify WLED pages load without JavaScript uncaught exceptions: index tests /index.htm and UI elements, settings iterates /settings*.htm routes, other-pages tests additional WLED HTML pages.
GitHub Actions CI workflow
.github/workflows/qemu-e2e-test.yml
Orchestrates the complete pipeline: build-firmware job compiles ESP32 QEMU firmware and uploads artifact; test-qemu job downloads artifact, launches QEMU, performs HTTP readiness checks, runs Playwright suite, analyzes logs for exceptions, uploads reports, and cleans up.
Documentation, gitignore, and implementation summary
IMPLEMENTATION_SUMMARY.md, docs/QEMU-ISSUES.md, e2e-tests/README.md, .gitignore
Adds comprehensive documentation covering overview, troubleshooting, and local/CI execution; updates gitignore to exclude Playwright and QEMU artifacts.

@copilot is it possible to run the e2e test with gcc sanitizing features enabled? Especially ThreadSanitizer would be interesting.

ThreadSanitizer and other GCC sanitizers have limited support for ESP32:

Challenges:

  1. Toolchain limitation: ESP32 uses Xtensa GCC which has incomplete sanitizer support compared to standard GCC
  2. Memory constraints: Sanitizers add significant overhead (2-20x memory, 2-5x slowdown) - ESP32 QEMU has limited RAM
  3. QEMU compatibility: ESP32 QEMU may not fully support sanitizer instrumentation

Potential alternatives:

  • Native x86 build with sanitizers (if WLED has host-target compilation mode)
  • Unit tests with sanitizers on host platform
  • Valgrind on QEMU (limited ESP32 support)

If you want to proceed, I can:

  1. Create a separate build environment with sanitizer flags (-fsanitize=thread)
  2. Attempt to enable it for QEMU testing
  3. Add error handling for likely failures

However, this is experimental and may not work reliably. Would you like me to attempt it, or would you prefer focusing on other testing approaches?

Added step to install required shared libraries before setting up QEMU:
- libsdl2-2.0-0 (SDL2 library - required by QEMU)
- libpixman-1-0 (pixel manipulation library)
- libglib2.0-0 (GLib library)

Enhanced setup-qemu.sh to verify dependencies after installation:
- Checks for missing libraries with ldd
- Shows QEMU version if successful
- Provides clear error message with install commands if libraries missing

This fixes the "error while loading shared libraries: libSDL2-2.0.so.0" error.

Port 80 is a privileged port requiring root permissions, which CI jobs
don't have and shouldn't require. Changed to use port 8080 instead:

- Updated workflow to use port 8080 for QEMU
- Changed default port in run-qemu.sh from 80 to 8080
- Updated all test URLs to use localhost:8080
- Updated README documentation with correct port
- Updated Playwright config default baseURL to use port 8080

This allows QEMU to start without requiring root/sudo privileges.

The or_flag field was renamed from or to avoid a C++ keyword conflict. Per coding guidelines, WLED-MM-specific modifications to vendored code should be marked with // WLEDMM comments to track local changes.

@copilot please analyze the log files i've uploaded in comment #303 (comment) .

It looks like the playwright tests are trying to access the WLED-MM WebUI pages directly, however the server routes from https://github.com/MoonModules/WLED-MM/blob/mdev/wled00/wled_server.cpp should be used: './', .'/settings/', './settings/sync', etc. (littleFS is initialized and functional, however web pages are directly served from the WLED firmware image).

Please iterate over the e2e test script until we have a working test that pulls all main UI elements (see original expectations in #302 ).

The tests were using filesystem-based paths like /index.htm and
/settings_wifi.htm which only work with LittleFS content. WLED serves
pages from compiled-in firmware data via route-based URLs:
- '/' for main UI (not /index.htm)
- '/settings' for settings landing
- '/settings/wifi', '/settings/leds', etc. for sub-pages
- '/welcome', '/liveview', '/update' for other pages
- '/json/info', '/json/state' for API endpoints

Also added JSON API validation tests.

@copilot please analyze the log files i've uploaded in comment #303 (comment) .

It looks like the playwright tests are tryin...

Fixed in the latest commit. The tests were using filesystem-based paths (/index.htm, /settings_wifi.htm) which only serve from LittleFS. WLED serves compiled-in pages via route-based URLs defined in wled_server.cpp:

  • / → main UI (compiled-in PAGE_index)
  • /settings → settings landing page
  • /settings/wifi, /settings/leds, /settings/sync, etc. → subpages (dispatched via url.indexOf() matching in serveSettings())
  • /welcome, /liveview, /update, /simple.htm → other pages

Updated tests:

  • index.spec.js: Tests / route, checks UI elements (#picker, #sliders), validates /json/info and /json/state API
  • settings.spec.js: Tests /settings, /settings/wifi, /settings/leds, /settings/ui, /settings/sync, /settings/time, /settings/sec, /settings/um, /settings/2D
  • other-pages.spec.js: Tests /simple.htm, /welcome, /update, /liveview

All pages verified for JavaScript uncaught exceptions (page errors).

All pages verified for JavaScript uncaught exceptions (page errors).

@copilot are the JS console logs available as CI job downloadable artifacts?

example

console.log("No array of holidays in holidays.json. Defaults loaded.");

- Create shared Playwright fixture that captures all browser console
  messages (log, warn, error, info, debug) and page errors per test
- Write logs to console-logs/ directory with one file per test
- Attach logs to Playwright HTML report for inline viewing
- Upload console-logs/ as separate CI artifact (7-day retention)
- Add console-logs/ to .gitignore

All pages verified for JavaScript uncaught exceptions (page errors).

@copilot are the JS console logs available as CI job downloadable artifacts?
...

Yes — JS console logs are now captured and available as CI artifacts. The implementation:

  1. Shared fixture (e2e-tests/fixtures.js) captures ALL browser console messages (log, warn, error, info, debug) plus uncaught page errors during each test
  2. Per-test log files written to console-logs/ directory (one .log file per test, named after the test title)
  3. CI artifact — uploaded as js-console-logs with 7-day retention, downloadable from the Actions run
  4. Inline in Playwright report — also attached to each test in the HTML report, so you can see console output alongside screenshots/traces

Example log output for a test:

[LOG] Loading WLED UI...
[WARN] WebSocket connection failed
[ERROR] Cannot read properties of undefined (reading 'x')
[PAGE_ERROR] Uncaught TypeError: ...

This will capture messages like the console.log at index.js:239 you referenced.

Settings pages have individual titles like "Usermod Settings", "2D Set-up",
"Wi-Fi Settings" etc. - not all contain "WLED". Updated tests to expect
the actual title served by each page.

@copilot the playwright tests seem to have wrong expectations.

    Expected pattern: /WLED/

...

Fixed in the latest commit. The issue was that settings.spec.js expected all settings pages to have /WLED/ in the title, but the actual HTML pages have individual titles:

  • /settings → "WLED Settings"
  • /settings/wifi → "Wi-Fi Settings"
  • /settings/leds → "LED Settings"
  • /settings/um → "Usermod Settings"
  • /settings/2D → "2D Set-up"
  • /settings/sec → "Misc Settings"
  • etc.

Updated the tests to expect the exact title each page actually serves (sourced from wled00/data/settings_*.htm <title> tags).

Remove redundant npm install @playwright/test``.

If @playwright/test is listed in package.json (which it should be per the PR), npm ci on line 91 already installs it. The explicit npm install @playwright/test`` creates a duplicate installation and may cause version drift if the package.json version differs.

Declare the Playwright test runner as a devDependency to keep installs deterministic.

test:e2e runs npx playwright test, while the repo directly imports @playwright/test (e.g., playwright.config.js, e2e-tests/fixtures.js, and e2e-tests/index.spec.js via page.request.get(...)). package.json only contains the test:e2e script and has no @playwright/test (or playwright) dependency, so CI/local runs depend on transient npx resolution.

@copilot I've found two error messages in the console logs, what do they mean? Is this a firmware problem, or maybe a consequence of firewalled execution inside the CI environment?

...

Both errors are expected firmware behavior in the QEMU build, not CI firewall issues:

1. /update → 501 (Not Implemented)
The QEMU build has -D WLED_DISABLE_OTA (platformio.ini line 2040). When the update page HTML loads, it references style.css via @import. The page itself loads fine through the settings dispatcher, but the browser also attempts to load some sub-resource that hits the explicit /update GET handler (line 435 in wled_server.cpp), which returns 501 because OTA is compiled out.

2. /simple.htm → 404 (Not Found)
The simple page HTML references simple.css and simple.js as separate files (line 53 and 262 in simple.htm). These are NOT compiled into the firmware as separate routes — they're only served from LittleFS via handleFileRead(). Since no custom UI files are uploaded to LittleFS in QEMU, the server returns 404.

Neither error causes JavaScript exceptions (the tests pass). They're just browser-reported network errors for resources that can't be served in this configuration. The simple.css/simple.js files would normally exist on LittleFS when uploaded by a user via the file editor, and OTA would be available in a production build without WLED_DISABLE_OTA.

No action needed — these are informational console messages, not bugs.

- enable OTA page
- enable simplified UI (optional)
- enable PixelForge

Declare @playwright/test as a devDependency.

The test:e2e script runs npx playwright test, and multiple files import from @playwright/test (playwright.config.js, e2e-tests/fixtures.js at line 2, and transitively e2e-tests/index.spec.js via fixtures), but package.json does not declare @playwright/test in devDependencies. This makes local and CI installs non-deterministic because npx fetches the package on-demand while the import statements require it to be installed in node_modules.

Assert navigation responses are successful before proceeding.

Both page.goto('/') calls (lines 28 and 49) do not capture or check the HTTP response. If the server returns an error status (4xx/5xx), the tests may still pass if the error page has a matching title or DOM structure. Capture the response and assert it's OK before checking page content.

🛡️ Proposed fix
     // The main UI is served at '/' (or '/sliders') from compiled-in PAGE_index
-    await page.goto('/');
+    const response = await page.goto('/');
+    expect(response?.ok(), 'Main UI should return HTTP 2xx/3xx').toBeTruthy();

Add @playwright/test to package.json instead of installing it inline.

Running npm install @playwright/test`` after npm ci modifies `node_modules` beyond the locked state, which can cause version drift and makes the Playwright dependency implicit rather than tracked in version control.

Suggested approach

Add to package.json devDependencies:

"devDependencies": {
  "`@playwright/test`": "^1.x"
}

Then simplify the step:

       - name: Install Playwright Browsers
-        run: |
-          npm install `@playwright/test`
-          npx playwright install --with-deps chromium

Replace fixed 3-second waits with condition-based waits.

Fixed timeouts (lines 34, 51) are brittle: they may be too short on slow CI runners or unnecessarily long on fast machines. Instead, wait for a specific DOM element or network condition that signals the UI is ready (e.g., await page.locator('#picker').waitFor() or await page.waitForSelector('#sliders')).

♻️ Suggested refactor
     // Wait for page to be loaded (don't wait for networkidle as API calls may hang)
     await page.waitForLoadState('load');
     
-    // Wait a bit for initial JavaScript to execute

Consider using async file write to avoid blocking the teardown phase.

fs.writeFileSync blocks the event loop during test teardown. While acceptable for small log files, switching to fs.promises.writeFile (or fs.writeFile with promisification) would be more consistent with the async fixture pattern and avoid potential blocking if logs grow large.

Add if-no-files-found: ignore to prevent upload failure when directory is missing.

The console-logs/ directory is only created by Playwright fixtures when tests actually run. If the workflow fails before Playwright executes any tests, this directory won't exist and the upload step will fail unnecessarily.

Navigation response not validated (persists from previous review).

Both page.goto('/sliders') calls (lines 30 and 50) ignore the HTTP response, so a 404 or 5xx could still pass if the title/DOM assertions happen to match. The JSON API tests (lines 60, 70) demonstrate the correct pattern with page.request.get() and explicit response.status() checks.

🔍 Proposed fix
-    await page.goto('/sliders');
+    const response = await page.goto('/sliders');
+    expect(response?.ok(), '/sliders should return HTTP 2xx/3xx').toBeTruthy();
     await page.waitForLoadState('load');

Apply the same pattern at line 50.

Filename collision risk remains unresolved.

Lines 40-41 contain the fix for the filename uniqueness issue raised in the previous review, but it's commented out with the note "not (yet) compatible with artefacts collection step." While the developer is aware of the collision risk (parallel runs or retries can overwrite the same .log file), deferring the fix means diagnostics may still be lost in multi-worker or retry scenarios.

Run the following script to verify whether the CI artifact collection step can handle unique suffixes in filenames:

#!/bin/bash
# Description: Check CI artifact upload patterns to understand filename constraints

# Search for artifact upload steps and path patterns

⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Redundant npm install may override locked dependency version.

npm ci (line 91) already installs dependencies from package-lock.json. Running npm install @playwright/test`` without a version specifier can install the latest version, potentially overriding the locked version and causing inconsistent test behavior.

If @playwright/test is already in package.json, remove the redundant install:

-        run: |
-          npm install `@playwright/test`
-          npx playwright install --with-deps chromium
