Register the plugin in your Rust code. **Important**: Only include this in debug builds: + + ```rust + // src-tauri/src/lib.rs or main.rs + + let mut builder = tauri::Builder::default(); + + // Only enable automation in debug builds + #[cfg(debug_assertions)] + { + builder = builder.plugin(tauri_plugin_automation::init()); + } + + builder + .run(tauri::generate_context!()) + .expect("error while running tauri application"); + ``` + + > ⚠️ **Warning**: Never include the automation plugin in release builds, as it could allow external control of your application. + +### Step 3: Set Environment Variable + +Set your CrabNebula API key as an environment variable: + +```bash +export CN_API_KEY="your-api-key-here" +``` + +For CI/CD, add this as a secret: + +**GitHub Actions:** +```yaml +env: + CN_API_KEY: ${{ secrets.CN_API_KEY }} +``` + +### Step 4: Configure WebdriverIO + +Update your `wdio.conf.ts` to use CrabNebula: + +```typescript +export const config = { + services: [ + ['@wdio/tauri-service', { + driverProvider: 'crabnebula', + crabnebulaManageBackend: true, // Auto-manage backend (default) + crabnebulaBackendPort: 3000, // Backend port (default) + }] + ], + + capabilities: [{ + browserName: 'tauri', + 'tauri:options': { + // Path to your debug binary + application: './src-tauri/target/debug/your-app-name', + } + }], + + // ... rest of your config +}; +``` + +### Step 5: Build Your App + +Build your Tauri app in debug mode: + +```bash +npm run tauri build -- --debug +``` + +Or with cargo directly: +```bash +cd src-tauri && cargo build +``` + +### Step 6: Run Tests + +Now you can run your WebdriverIO tests: + +```bash +npm run wdio +``` + +## Troubleshooting + +### "CN_API_KEY is not set" + +**Solution**: Ensure the environment variable is set: +```bash +echo $CN_API_KEY # Should show your API key +``` + +If empty, set it: +```bash +export CN_API_KEY="your-api-key" +``` + +### "@crabnebula/tauri-driver not found" + +**Solution**: Install the package: +```bash +npm install -D @crabnebula/tauri-driver +``` + +### "tauri-plugin-automation not found" + +**Solution**: Add the plugin to your Tauri app: +```bash +cd src-tauri && cargo add tauri-plugin-automation +``` + +Then ensure it's registered in your Rust code with the `#[cfg(debug_assertions)]` guard. + +### "test-runner-backend exited with code X" + +**Possible causes**: +- Invalid or expired CN_API_KEY +- Port 3000 already in use (change `crabnebulaBackendPort`) +- macOS security restrictions + +**Solutions**: +1.
