QA & Testing
Automated testing, performance audits, and security testing for production-grade quality. End-to-end test suites with Playwright, unit testing with Jest, load testing, and accessibility audits — quality built into your CI/CD pipeline.
Shipping fast without breaking things requires automated testing at every layer of your application: unit tests for business logic and utility functions, integration tests for API contracts and database operations, and end-to-end tests for critical user flows like signup, checkout, and onboarding. We build comprehensive test suites that run automatically in your CI pipeline and catch regressions before they ever reach production.
Our testing stack is modern and battle-tested: Jest for unit and integration testing with fast parallel execution, Playwright for cross-browser end-to-end testing (Chromium, Firefox, WebKit), and Cypress for component-level testing when visual verification matters. Every test suite includes fixtures, factories, and seed data for reproducible test environments.
Beyond functional correctness, we cover performance testing (load testing with k6 or Artillery, Core Web Vitals monitoring, database query performance), security testing (OWASP Top 10 vulnerability scanning, dependency auditing with npm audit and Snyk, static analysis), and accessibility testing (automated axe-core checks plus manual screen reader verification for WCAG 2.1 AA compliance).
Every test failure blocks the deployment pipeline — quality gates are non-negotiable. We also set up flaky test detection and quarantine so unreliable tests don't erode your team's confidence in the test suite over time.

Frequently Asked Questions
We automate everything that can be reliably automated and produces consistent, repeatable results: unit tests for business logic, API integration tests, regression suites for existing functionality, and end-to-end tests for critical user flows like login, checkout, onboarding, and payment processing. These automated tests run on every pull request and block merges when they fail, catching regressions before they reach production. Manual testing is reserved for areas where human judgment adds real value: exploratory testing to discover unexpected behavior, usability evaluation of new features, testing complex visual layouts across devices, and edge cases that are difficult or impractical to script (like testing with real payment providers in sandbox mode). For most projects, we target 80%+ automated coverage of critical user paths, supplemented by manual QA sessions for every new feature before it ships. The ratio typically works out to 85-90% automated and 10-15% manual effort.
We target 80%+ code coverage for business-critical modules and 100% coverage for high-risk code paths: payment processing, authentication and authorization, data encryption, and personally identifiable information handling. However, coverage percentage alone is a misleading metric — a test suite with 60% coverage of the right code is significantly more valuable than 95% coverage that misses the checkout flow or authentication edge cases. Our approach prioritizes coverage of critical user journeys end-to-end (signup → onboarding → core action → payment), error handling paths (what happens when the API is down, payment fails, or session expires), and boundary conditions (empty states, maximum input lengths, concurrent operations). We use Istanbul/nyc for coverage reporting integrated into CI, with per-module thresholds that prevent coverage from decreasing over time. Coverage reports are reviewed during code reviews to ensure new code includes meaningful tests, not just tests written to hit a number.
Yes — security testing is integrated into our QA process at multiple levels. We cover the OWASP Top 10 vulnerabilities systematically: SQL injection and NoSQL injection (parameterized queries, ORM validation), cross-site scripting or XSS (output encoding, Content Security Policy headers), cross-site request forgery or CSRF (token validation), broken authentication (session management, password policies, brute-force protection), insecure direct object references (authorization checks on every endpoint), security misconfiguration (HTTP headers, CORS, TLS settings), and sensitive data exposure (encryption at rest and in transit). Automated security scanning runs in CI on every build: dependency vulnerability auditing with npm audit and Snyk to catch known CVEs in third-party packages, static analysis with tools like ESLint security plugins and Semgrep for code-level vulnerabilities. Every API endpoint is tested for authorization bypass — ensuring users cannot access resources belonging to other users or escalate their permissions. For applications handling sensitive data (healthcare, finance, PII), we coordinate manual penetration testing with certified security professionals as an add-on service.
