Potential causes: + +1. **WASM Module Loading** + - Circuit files trying to load during test + - WASM initialization failing in Playwright environment + - File: `src/lib/zkml/circuit-manager.ts` + +2. **Web Workers** + - Proof generation uses Web Workers + - Workers may not initialize properly in test environment + - File: `src/lib/proof/worker-pool.ts` + +3. **IndexedDB** + - Circuit caching uses IndexedDB + - May have permissions/access issues in Playwright + - File: `src/lib/zkml/circuit-manager.ts` (Circuit) + +4. **Browser API Access** + - Some component accessing unavailable browser APIs + - SharedArrayBuffer, WebGL, or other restricted APIs + - Need to check component initialization code + +5. **Sentry Integration** + - Sentry SDK may be causing issues in test environment + - Error reporting initialization may fail + - File: `src/hooks.client.js` + +--- + +## Recommended Next Steps + +### High Priority (1-2 hours) + +1. **Add Debugging to Components** + - Add try-catch blocks in ZKMLProver component + - Add console.logs to track initialization + - Identify exact point of crash + +2. **Mock WASM/Workers in Tests** + - Create test fixtures that mock circuit loading + - Stub out Web Worker creation + - Mock IndexedDB operations + +3. **Run Tests with Debug Logging** + + ```bash + DEBUG=pw:api npm run test:e2e -- --headed + ``` + + - Watch browser window for errors + - Capture console output from page + +### Medium Priority (2-3 hours) + +4. **Create Test-Specific Build** + - Add environment flag for testing + - Disable WASM loading in test mode + - Use mock circuit data + +5. **Simplify Test Cases** + - Create minimal smoke tests that don't interact with proof generation + - Test basic navigation and rendering only + - Gradually add complexity + +6. **Review Component Lifecycle** + - Check onMount hooks in components + - Verify no synchronous API calls + - Ensure proper error handling + +### Low Priority (4+ hours) + +7. **Alternative Testing Approach** + - Consider using @testing-library/svelte for component tests + -
