Create audit configuration in `src/services/audits/audit-config.ts` if needed 2. Use `AuditExecutor` from `src/services/audits/audit-executor.ts` 3. Execute audit via appropriate method: - `executeAxeAudit(url, config)` for axe-core - `executeLighthouseAudit(url, config)` for Lighthouse - `executeWaveAudit(url, config)` for WAVE API 4. Save results to `/reports` directory as JSON files with timestamp 5. Return normalised audit results ## Output Format Results must be saved as JSON files in `/reports` directory: - Filename format: `{tool}-{timestamp}.json` - Content: Normalised audit result from `NormalisedAuditResult` type ## Configuration Use consistent configuration: - Timeout: 30000ms default - Browser: chromium default - Tags: Include WCAG tags for axe-core (e.g., ["wcag2a", "wcag2aa"]) ## Example ```typescript import { AuditExecutor } from './services/audits/audit-executor.js'; import { writeFile } from 'fs/promises'; const executor = new AuditExecutor(); const result = await executor.executeAxeAudit('https://example.com'); await writeFile(`reports/axe-${Date.now()}.json`, JSON.stringify(result, null, 2)); ```
