5.3 Test Execution & Defect Tracking

• Lead: QA Team

• Tool: Jira + TestRail (optional for large teams)

Weekly Testing Cycle:

Monday-Wednesday: Test Execution

• ├─ Run regression tests on new build

• ├─ Test new features

• ├─ Document results

• └─ Report defects

Example daily standup:

QA Lead: "We found 3 bugs yesterday:

1. Login error not showing (HIGH)

2. Payment history pagination broken (MEDIUM)

3. Typo in email template (LOW)

We're targeting 95% test pass rate by Friday."

Wednesday: Defect Triage

• ├─ Review all bugs reported

• ├─ Assign severity

• ├─ Assign to developer

• └─ Agree on resolution target

Thursday-Friday: Verification

• ├─ Retest fixed bugs

• ├─ Run regression on fixes

• ├─ Verify no new issues

• └─ Sign off on build quality

Status Report (Friday): Total Tests: 250 Passed: 240 (96%) Failed: 10 (4%) Bugs Fixed: 8 Outstanding: 2 (assigned, in progress) Ready for UAT: YES

5.4 Automated Testing

• Framework: Jest (unit), Playwright/Cypress (E2E; AI-generated starter suites permitted)

• Coverage Target: >80%

Test Suite Structure:

/tests

• ├─ unit/

• │├─ auth.test.js (Login, signup, password reset)

• │├─ payment.test.js (Payment processing)

│└─ wallet.test.js (Wallet management) ├─ integration/ │├─ auth-flow.test.js (Register → Login → Dashboard) │├─ payment-flow.test.js (Add card → Payment → Email) │└─ api-integration.test.js (API endpoints) ├─ e2e/ │├─ login-flow.test.js (Full user login journey) │├─ payment-journey.test.js (Complete payment) │└─ error-scenarios.test.js (Error handling) └─ performance/ ├─ load-test.js (1000 concurrent users) └─ stress-test.js (Spike to 5000 users)

Example test (Jest): describe('Payment Processing', () => { test('should process valid payment', async () => { const paymentData = { amount: 99.99, paymentMethodId: 'pm_test_valid', currency: 'USD' }; const result = await paymentService.process(paymentData); expect(result.status).toBe('completed'); expect(result.transactionId).toBeDefined(); }); test('should reject invalid amount', async () => { const paymentData = { amount: -10, paymentMethodId: 'pm_test_valid' }; await expect(paymentService.process(paymentData)) .rejects .toThrow('Amount must be positive'); }); });

5.5 Performance Testing

• Tool: Apache JMeter or Load.io

• Targets:

  • API response time: <200ms (95th percentile)

  • Page load: <3 seconds

  • Concurrent users: 1000+

– Transactions: 500/second

Performance Test Scenario:

Test: Login spike during marketing campaign

• ├─ Baseline: 100 users/sec (constant)

• ├─ Spike: Increase to 500 users/sec over 5 minutes

• ├─ Sustain: 500 users/sec for 30 minutes

• └─ Cool down: Return to 100 users/sec

Metrics to Monitor:

• ├─ Response time: Should stay <200ms

• ├─ Error rate: Should stay <0.1%

• ├─ CPU usage: Should stay <80%

• ├─ Memory: Should stay <75%

• ├─ Database connections: Should stay <80% max

Result: PASS

• ├─ Peak response time: 185ms

• ├─ Error rate: 0.05%

• ├─ No timeout errors

• └─ System recovered cleanly after spike

5.6 Security Testing

• Lead: Security Engineer / QA

• Tools: OWASP ZAP, Burp Suite

• Focus Areas:
