Quality Assurance: Comprehensive Test Coverage and Flaky Test Triage

Overview

This PR implements comprehensive quality improvements across four interconnected GitHub issues, adding authorization testing, E2E coverage for settings/privacy journeys, visual regression testing, and automated flaky test reporting with triage workflow.

Issues Addressed

Closes #680
Closes #681
Closes #682
Closes #683

Changes Summary

1. Authorization-Failure Tests for Backend Routes (#681 - P0)

File: backend/tests/authorization-routes.test.ts (373 lines)

Implements explicit authorization-failure tests for all backend route groups to ensure security-sensitive APIs correctly enforce 401 and 403 responses.

Coverage:

• Subscriptions routes (GET, POST)
• Audit routes (GET, POST)
• Compliance routes (account deletion, data export)
• API Keys routes (role-based access control)
• Webhooks routes (admin/owner only)
• User routes (profile access and updates)

Test Cases: 20+ test cases verifying:

• 401 Unauthorized responses for unauthenticated requests
• 403 Forbidden responses for insufficient permissions
• Role-based access control (owner, admin, member, viewer)
• Scope-based authorization for API keys
• Authorization failure patterns across all route groups

Acceptance Criteria Met:

• ✅ Route inventory includes authz tests for each endpoint family
• ✅ Test failures block merges (Jest tests fail on auth violations)
• ✅ Missing protections discovered during test writing are fixed

2. Playwright E2E Coverage for Settings and Privacy Journeys (#680 - P1)

File: client/e2e/settings-privacy.spec.ts (350 lines)

Adds comprehensive end-to-end tests for settings, privacy export, deletion request, MFA, and email preferences journeys.

Test Coverage (13 test cases):

• Settings page access and navigation
• Email preferences management and updates
• Privacy export and data download functionality
• Account deletion request and cancellation flows
• MFA enable/disable functionality
• Notification preferences management
• Authentication failure handling
• Responsive design on mobile viewports
• Loading state verification
• Dark mode appearance

Acceptance Criteria Met:

• ✅ Core settings journeys covered end to end
• ✅ Auth and failure paths included
• ✅ CI artifacts include screenshots on failure (via Playwright's built-in screenshot feature)

3. Flaky Test Reporting and Triage Workflow (#682 - P2)

Files:

• client/lib/test-utils/flaky-reporter.ts (enhanced, +102 lines)
• .github/workflows/flaky-test-triage.yml (new, 122 lines)

Wires flaky test reporting into the triage workflow with automatic issue creation, PR comments, and persistent tracking.

Flaky Reporter Enhancements:

• Triage status tracking (new, acknowledged, investigating, resolved)
• Severity classification (critical >50%, warning 30-50%, info <30%)
• Triage guidance with debug steps
• Markdown report generation for CI artifacts
• Persistent flaky test data for chronic test tracking
• CI failure on critical flaky tests

GitHub Actions Workflow:

• Triggered on E2E test workflow completion
• Automatically creates GitHub issues for critical flaky tests (>50% flake rate)
• Comments on PRs with flaky test summaries
• Uploads markdown reports as CI artifacts
• Provides triage guidance to owners
• Fails CI if critical tests detected

Acceptance Criteria Met:

• ✅ Flaky runs persisted in CI artifacts (JSON + Markdown)
• ✅ Owners receive triage guidance (GitHub issues + PR comments)
• ✅ Chronic flaky tests tracked explicitly (persistent JSON data)

4. Visual Regression Coverage for Dashboard and Onboarding (#683 - P2)

Files:

• client/e2e/visual-regression.spec.ts (403 lines)
• client/docs/VISUAL_REGRESSION_TESTING.md (203 lines)

Adds visual regression testing for dashboard and onboarding flows with baseline snapshots, responsive design verification, and comprehensive documentation.

Visual Regression Tests (20+ test cases):

• Dashboard layout tests (desktop, mobile, tablet)
• Subscription list component regression
• Spending chart visualization regression
• Dashboard header regression
• Onboarding flow step-by-step regression
• Mobile onboarding regression
• Tour highlight regression

Responsive Design Tests:

• 5 viewport sizes tested (320px to 1920px)
• Horizontal scroll verification
• Layout adaptation verification
• Component visibility verification

Additional Tests:

• Dark mode visual regression (dashboard, onboarding)
• Accessibility focus indicator verification

Documentation:

• Comprehensive visual regression testing guide
• Baseline management procedures
• CI/CD integration details
• Best practices and troubleshooting
• Responsive design testing guide
• Dark mode testing guide

Acceptance Criteria Met:

• ✅ Baseline snapshots exist for key pages
• ✅ Review workflow for intentional changes documented
• ✅ Responsive variants included (5 viewports)
