+# WLED-MM Wokwi Simulation Testing
+
+This directory contains configuration and tests for running WLED-MM in the Wokwi ESP32 simulator with Playwright-based web interface testing.
+
+## Overview
+
+The Wokwi testing workflow:
+1. Builds the WLED firmware for ESP32
+2. Runs the firmware in the Wokwi ESP32 simulator
+3. Uses Playwright to test the web interface
+4. Verifies pages load without JavaScript errors
+
+## Files
+
+- `diagram.json` - Wokwi hardware configuration (ESP32 DevKit)
+- `wokwi.toml` - Wokwi CLI configuration and port forwarding
+- `prepare-firmware.sh` - Script to copy built firmware to test directory
+- `run-simulator.sh` - Script to start the Wokwi simulator
+
+## Running Tests Locally
+
+### Prerequisites
+
+1. Install Node.js dependencies:
+   ```bash
+   npm ci
+   ```
+
+2. Install Wokwi CLI:
+   ```bash
+   curl -L https://wokwi.com/ci/install.sh | sh
+   ```
+
+3. Install Playwright browsers:
+   ```bash
+   npx playwright install --with-deps chromium
+   ```
+
+### Build and Test
+
+1. Build the web interface:
+   ```bash
+   npm run build
+   ```
+
+2. Build the firmware:
+   ```bash
+   pio run -e esp32dev_compat
+   ```
+
+3. Prepare firmware for testing:
+   ```bash
+   ./test/wokwi/prepare-firmware.sh esp32dev_compat
+   ```
+
+4. Start the Wokwi simulator (in a separate terminal):
+   ```bash
+   cd test/wokwi
+   ./run-simulator.sh
+   ```
+
+5. Run Playwright tests (in another terminal):
+   ```bash
+   npm run test:wokwi
+   ```
+
+## CI Integration
+
+The GitHub Actions workflow (`.github/workflows/wokwi-test.yml`) automatically runs these tests on:
+- Push to `mdev` branch
+- Pull requests to `mdev` branch
+- Manual workflow dispatch
+
+## Test Cases
+
+The Playwright tests (`test/playwright/wokwi-basic.spec.js`) verify:
+- Main index page loads without errors
+- Settings pages load without errors
+- Edit page loads without errors
+- JSON API endpoints respond correctly
+
+## Extending Tests
+
+To add more tests:
+1. Edit `test/playwright/wokwi-basic.spec.js`
+2. Add new test cases using Playwright's `test()` function
+3. Follow the existing pattern of checking for console errors
+
+## Troubleshooting
+
+### Simulator doesn't start
+- Check that firmware.bin exists in test/wokwi/
+- Verify Wokwi CLI is installed: `wokwi-cli --version`
+- Check Wokwi CLI logs for errors
+
+### Web server not accessible
+- Wait 30-60 seconds for the ESP32 to boot and start WiFi
+- Check that port 8080 is not already in use
+- Verify port forwarding in wokwi.toml
+
+### Tests fail
+- Check Playwright report: `npx playwright show-report`
+- Look for console errors in test output
+- Verify firmware build completed successfully
+

Subject: [PATCH 13/29] Switch to esp32_V4_wokwi_debug build and improve debug
 output collection

- Update workflow to use esp32_V4_wokwi_debug environment (added by @softhack007)
- Separate serial output from Wokwi CLI diagnostic messages
- Increase timeout to 240 seconds for web server startup
- Increase simulator timeout to 300 seconds
- Capture serial.log and wokwi.log separately
- Display first 50 lines of serial output on success
- Display last 100 lines of both logs on failure
- Update README.md with new build environment
- Add better visual separators and emoji indicators in logs

Subject: [PATCH 14/29] Add boot validation scenarios for quick firmware
 testing

- Create boot-check.yaml: 12-second quick boot validation
- Create boot-full.yaml: 30-second comprehensive boot validation
- Add CI step for quick boot check before Playwright tests
- Update README.md with scenario documentation and usage examples
- Boot check runs as pre-flight validation in CI workflow
- Both scenario logs uploaded as artifacts for analysis

+## Boot Validation Scenarios
+
+Wokwi CLI supports test scenarios that can validate firmware boot without requiring a full Playwright test suite. Two scenarios are provided:
+
+### Quick Boot Check (`scenarios/boot-check.yaml`)
+A fast 12-second validation that ensures WLED boots without immediate crashes.
+
+**Features:**
+- Simple delay-based validation
+- Total runtime: ~12 seconds
+- Fails if simulator crashes or hangs during boot
+- Perfect for CI pre-flight checks
+
+**Usage:**
+```bash
+cd test/wokwi
+~/.wokwi-ci/bin/wokwi-cli --timeout 20000 --scenario scenarios/boot-check.yaml .
+```
+
+### Comprehensive Boot Validation (`scenarios/boot-full.yaml`)
+A thorough 30-second validation with extended timing for WiFi AP and HTTP server initialization.
+
+**Features:**
+- Allows full system initialization
+- Total runtime: ~30 seconds
+- More detailed validation
+- Better for local testing and troubleshooting
+
+**Usage:**
+```bash
+cd test/wokwi
+~/.wokwi-ci/bin/wokwi-cli --timeout 40000 --scenario scenarios/boot-full.yaml .
+```
+
+### Creating Custom Scenarios
+
+You can create your own scenario files in YAML format:
+
+```yaml
+version: 1
+timeout: 15000  # milliseconds
+
+steps:
+  - name: "Description of step"
+    sleep: 5000  # wait 5 seconds
+```
+
+The scenario will fail if:
+- The simulator crashes during execution
+- The timeout is exceeded
+- Any step encounters an error
+
 ## Extending Tests
 
 To add more tests:
 1. Edit `test/playwright/wokwi-basic.spec.js`
 2. Add new test cases using Playwright's `test()` function
 3. Follow the existing pattern of checking for console errors
+4. Create custom scenario files in `scenarios/` directory

Subject: [PATCH 15/29] Handle WebSocket connection errors gracefully in boot
 validation

- Increase boot check scenario timeout from 12s to 15s for slower CI environments
- Increase CLI timeout from 20s to 30s to account for network delays
- Add version check and better error handling for code 1006 (WebSocket closure)
- Make boot check non-fatal for transient network issues
- Continue with full simulation test if boot check has network errors
- Update README with new timings and error handling notes

Subject: [PATCH 16/29] Fix Wokwi CLI path issue in boot validation step

- Add Wokwi CLI bin directory to PATH in boot validation step
- Use 'wokwi-cli' command instead of full path for better portability
- Add verification step to confirm Wokwi CLI installation
- Display CLI location and directory contents for debugging
- Update boot check timing references (12s -> 15s for consistency)

Subject: [PATCH 22/29] Fix scenario step key: use 'delay' with time units
 instead of 'wait'

- Change 'wait: 6000' to 'delay: 6s' in boot-check.yaml
- Change 'wait: 8000/10000/8000/4000' to 'delay: 8s/10s/8s/4s' in boot-full.yaml
- Wokwi CLI requires 'delay' with time units (e.g., '6s', '200ms')
- Fixes "Invalid scenario step key: wait" error
- Correct format per Wokwi documentation

Subject: [PATCH 24/29] Optimize CI workflow: move Playwright install after
 boot check and collect serial output

Changes:
- Move "Install Playwright browsers" step after boot validation
  - Saves time if boot check fails (no need to install Playwright)
  - Playwright only installed if firmware boots successfully
- Collect serial output from boot check scenario
  - Separate serial output (stdout) to boot-check-serial.log
  - Keep CLI diagnostics (stderr) in boot-check.log
  - Display both logs on success and failure
  - Better debugging with separate log streams

Benefits:
- Faster feedback on boot failures (skip Playwright install)
- More comprehensive boot check debugging
- Clearer separation of concerns in logs

Subject: [PATCH 26/29] Enable serial monitor in diagram.json and add firmware
 verification

Critical fix for missing serial output:
- Add serialMonitor configuration to diagram.json with display:"always"
  - Required for capturing serial output in headless/CI mode
  - Without this, firmware output is not recorded
- Add firmware hexdump verification in boot check workflow
  - Displays first 64 bytes to verify valid ESP32 header (0xe9 magic byte)
  - Helps diagnose corrupt or invalid firmware files
- Update README with comprehensive Serial Monitor Configuration section
  - Explains why serialMonitor config is required
  - Documents configuration options
  - Adds troubleshooting steps for missing serial output
  - Includes firmware verification commands

This should resolve the issue where boot check runs but shows no firmware serial output

+```json
+"serialMonitor": {
+  "display": "always",
+  "newline": "lf"
+}
+```
+
+**Why this is needed:**
+- Without `display: "always"`, serial output is not captured in headless/CI mode
+- The Wokwi simulator only records serial output when explicitly configured
+- This is **required** for debugging boot issues and verifying firmware execution
+
+**Configuration options:**
+- `display: "always"` - Ensures serial output is captured even in headless mode (CI)
+- `display: "auto"` - Only shows serial monitor when running interactively (not suitable for CI)
+- `newline: "lf"` - Line ending format (LF for Unix-style, CRLF for Windows)
+
+**Troubleshooting missing serial output:**
+If you see empty serial logs (`boot-check-serial.log` or `serial.log`):
+1. Verify `serialMonitor` section exists in `diagram.json`
+2. Check firmware.bin has valid ESP32 header (starts with `0xe9` magic byte)

Subject: [PATCH 29/29] Add bootloader and partitions support for ESP32
 filesystem

Critical fix for "partition not found" errors in serial output:

- Update wokwi.toml to include bootloader.bin and partitions.bin
  - Bootloader flashed at 0x1000 (standard ESP32 location)
  - Partitions flashed at 0x8000 (partition table location)
  - These are required for ESP32 filesystem (SPIFFS) support

- Update prepare-firmware.sh to copy additional files:
  - bootloader.bin from build directory
  - partitions.bin from build directory
  - Shows checkmarks for successful copies
  - Lists all files at end for verification

- Update README.md with Flash Files Configuration section:
  - Explains why bootloader and partitions are needed
  - Documents flash memory layout
  - Shows complete wokwi.toml configuration

- Update .gitignore to exclude bootloader.bin and partitions.bin

Without these files, ESP32 cannot access filesystem which causes
initialization errors. This resolves the partition-related errors
seen in the serial output.

 ## Files
 
 - `diagram.json` - Wokwi hardware configuration (ESP32 DevKit) with serial monitor settings
-- `wokwi.toml` - Wokwi CLI configuration and port forwarding
-- `prepare-firmware.sh` - Script to copy built firmware to test directory
+- `wokwi.toml` - Wokwi CLI configuration, flash files, and port forwarding
+- `prepare-firmware.sh` - Script to copy built firmware, bootloader, and partitions to test directory
 - `run-simulator.sh` - Script to start the Wokwi simulator
+- `firmware.bin` - Main firmware binary (copied from build)
+- `firmware.elf` - Firmware with debug symbols (copied from build)
+- `bootloader.bin` - ESP32 bootloader (copied from build, flashed at 0x1000)
+- `partitions.bin` - Partition table (copied from build, flashed at 0x8000)
+
+## Flash Files Configuration
+
+The simulator requires multiple binary files to properly emulate ESP32 boot and filesystem:
+
+**wokwi.toml flash configuration:**
+```toml
+[wokwi]
+firmware = "firmware.bin"        # Main application code
+elf = "firmware.elf"             # Debug symbols
+partitions = "partitions.bin"    # Partition table
+
+[[wokwi.flashFiles]]
+offset = 0x1000                  # Bootloader location
+file = "bootloader.bin"
+
+[[wokwi.flashFiles]]
+offset = 0x8000                  # Partition table location
+file = "partitions.bin"
+```
+
+**Why these files are needed:**
+- `bootloader.bin` - ESP32 second-stage bootloader, loads the application
+- `partitions.bin` - Partition table defining flash memory layout (app, SPIFFS, etc.)
+- Without these, filesystem operations will fail with "partition not found" errors
+- Standard ESP32 flash layout: bootloader@0x1000, partitions@0x8000, app@0x10000
