Software Testing & QA
Software testing pyramid (unit, integration, E2E) & API load and stress testing services with Playwright, k6 benchmarks & OWASP verification.
Direct Answer Summary
Rohini builds automated software testing and QA pipelines across all five critical layers: deterministic Unit tests, contract-verified Integration tests, cross-browser Playwright End-to-End (E2E) suites, k6 Performance and Load testing, and OWASP Security audits. We wire every suite into CI/CD quality gates so teams ship faster with zero production regressions.

Technical Architecture Breakdown
1. Unit & Integration Testing (Foundation)
Pure domain logic is covered by millisecond unit tests, while APIs and database queries run against ephemeral Testcontainers PostgreSQL/Redis instances.
2. Deterministic Playwright E2E Suites
Critical user journeys—signup, checkout, lead forms, and RBAC flows—run headlessly across Chromium, WebKit, and mobile viewports without flaky sleeps.
3. Performance, Load & Soak Testing (k6)
Scripted virtual-user ramps validate throughput, memory leaks, and connection-pool limits under 2x–5x expected peak traffic.
4. Security & OWASP Verification
Automated dependency scanning, auth/IDOR boundary tests, rate-limit checks, and XSS/SQLi input fuzzing protect production endpoints.
Production Tech Stack Matrix
| Layer | Technologies | Architectural Rationale | Production Guarantee |
|---|---|---|---|
| Unit & Contract | Node Test Runner, Vitest, Jest, Pytest, Zod | Fast feedback in < 5 seconds on every commit | Deterministic zero-flake runs |
| Integration | Supertest, Testcontainers (Postgres/Redis) | Tests real SQL migrations and cache behavior | Catches schema drift early |
| E2E & Visual | Playwright, Trace Viewer, Axe Accessibility | Real browser verification on desktop & mobile | Zero broken critical flows |
| Load & Security | Grafana k6, OWASP ZAP, Semgrep, npm audit | Quantifies breaking points and closes vuln gaps | Documented SLA benchmarks |
Commercial Use-Case Matrix
| Scenario | Core Requirement | Delivered System | Outcome |
|---|---|---|---|
| Pre-Launch SaaS / E-Commerce | Verify checkout, webhooks & peak load | Playwright E2E + k6 load suite + security pass | Confident zero-downtime launch |
| Legacy Codebase Refactoring | Prevent regressions while modernizing | Characterization + integration test harness | Safe weekly deployments |
| High-Traffic API Platforms | Prove 1,000+ RPS under SLA | k6 spike/soak tests in CI/CD | Verified p99 < 150ms |

Frequently Asked Questions
Can you set up automated QA for an app built by another team?
Yes. We audit existing repositories, add Playwright E2E and API integration suites, and wire them into GitHub Actions or GitLab CI.
What is included in Performance & Load testing?
We write k6 scripts simulating realistic traffic, spike, and soak scenarios, then deliver p95/p99 latency reports and bottleneck fixes.
Do you test security vulnerabilities like broken access control and injection?
Yes. We test authentication boundaries, RBAC/IDOR isolation, rate limiting, CSRF/XSS protections, and dependency CVEs.
