# Webapp Testing (FlowBRE E2E & Latency Benchmark Edition) Browser-driven and API testing using Playwright to verify `flow.html` UI interaction, FastAPI endpoint correctness, latency SLAs, and memory garbage collection baseline. ## Testing & Audit Directives 1. **Automated Latency SLA Verification Under Load**: - Simple GET endpoints (`GET /health`): Assert response latency is **`< 30 ms`**. - Onboarding evaluation CRUD endpoints (`POST /evaluate`): Assert end-to-end latency is **`< 80 ms`**. - Zen-Engine rule evaluation: Assert Rust core execution is **`< 10 ms`**. - Total pipeline latency: Assert **`< 100 ms`**. 2. **Post-GC Baseline Memory Verification**: - Execute batch request runs and measure CPython process RSS memory. - Confirm that following Stage 4 (`Garbage Collection`), memory reference counts drop to zero and heap allocations return to baseline (`Stage 5: Memory Released`), preventing process memory leaks. 3. **Single-File UI & Bidirectional Sync Verification (`flow.html`)**: - Launch Playwright against local `flow.html`. - Interact with Step 4 onboarding inputs (`cibilScore`, `dpdCount`, `income`). - Assert that Tab 2 simulator decision cards and decision alert banners update in real-time without JavaScript console errors. 4. **Capture Evidence**: - Record exact latency distribution logs and take Playwright screenshots of decision output banners for empirical task verification.
