Software Quality Assurance That Ships Confidence
End-to-end software testing and quality assurance — manual and automated — to catch bugs early, improve reliability, and deliver products that users trust.
ZTABS provides qa & testing — End-to-end software testing and quality assurance — manual and automated — to catch bugs early, improve reliability, and deliver products that users trust. Our capabilities include test automation, manual qa, performance testing, and more.
How We Approach QA & Testing
Shipping buggy software is the fastest way to lose users and credibility. ZTABS provides comprehensive QA and testing services — from test strategy and planning through manual testing, automation frameworks, and CI/CD integration. We work as an embedded QA team alongside your developers or as a standalone testing partner for pre-launch audits.
Our automation stack includes Playwright and Cypress for end-to-end browser testing, Jest and Vitest for unit and integration tests, k6 and Artillery for load and performance testing, and Appium for mobile app testing. We write tests that run in your CI pipeline (GitHub Actions, GitLab CI, CircleCI) so every pull request is validated automatically. For manual testing, we cover functional testing, exploratory testing, cross-browser compatibility, responsive design verification, and accessibility audits (WCAG 2.1 AA).
We also specialize in API testing using Postman and custom scripts, security testing including OWASP Top 10 checks, and regression testing to ensure new features don't break existing functionality. Every engagement starts with a test strategy document that defines scope, risk areas, test types, and coverage targets. We provide detailed bug reports with reproduction steps, screenshots, and severity classifications.
QA engagements range from $5K for a pre-launch audit to $10K-$25K/month for ongoing embedded QA teams.
Common Use Cases for QA & Testing
- Pre-launch quality audits for web and mobile applications
- Automated test suite setup for CI/CD pipelines
- Regression testing for large codebases with frequent releases
- Cross-browser and cross-device compatibility testing
- Performance and load testing before scaling events
- Accessibility compliance testing (WCAG 2.1, Section 508)
- API testing for microservices and third-party integrations
- Security testing and vulnerability scanning
