About the Service
We check stability, logic, performance, edge-case behavior, and adherence to expected user flows. From websites and mobile apps to chatbots, APIs, AI tools, IoT systems, and more — we test digital products at any stage: pre-release, post-development, or during scaling. We create test cases, build checklists, perform manual and automated testing (Playwright, PyTest, Postman), and prepare full documentation with screenshots, logs, and detailed reports. We integrate with your workflow — Jira, Notion, Trello, or any format you prefer.
With us, you get not just development, but a reliable technology partner ensuring your business success.

Frequently Asked Questions
What does Momentum Squads' Quality Assurance service cover?
We deliver the full QA pipeline: from requirements analysis and test-strategy creation to manual and automated testing. We verify functionality, security, performance and usability of your product.
What's the difference between a tester and a QA engineer?
A tester focuses on finding bugs in code that's already written. A QA engineer prevents bugs at the architecture-planning stage, designing the development process so the product is high-quality by default.
When should you use manual testing vs automated testing?
Manual testing is ideal for new projects, UI and UX validation. Automation pays off on large projects with regular updates, where you need to recheck legacy functionality (regression testing) — saving time and budget long-term.
Do you run performance and load testing?
Yes — we measure how your site or app behaves under high concurrency. That surfaces architectural bottlenecks and proves the system won't fall over during peak traffic or marketing campaigns.
What types of testing do you perform on mobile apps?
We test on real iOS and Android devices: behaviour on different networks (Wi-Fi, 4G/5G), correct rendering across screen resolutions, energy consumption and integration with the phone's system features.
How does QA actually reduce development cost?
Fixing a bug found at the idea or design stage is dozens of times cheaper than fixing the same bug after release. A solid QA process shortens Time-to-Market and prevents losing customers to technical failures.
Which tools do you use for test automation?
Our stack: Selenium, Playwright and Cypress for web; Appium for mobile. We write autotests in Python and JavaScript and integrate them into CI/CD so every change is verified automatically.
Do you provide bug reports and overall product status?
Always. After every testing cycle you receive a detailed Bug Report describing the issues found, reproduction steps and fix recommendations, plus a release-readiness overview.
Do you do security testing?
Yes — we test the system against SQL injection, XSS and other vulnerabilities. We verify protection of personal data and the correctness of encryption protocols, so your business stays safe.
How do I engage your QA team?
We can plug in at any project stage. We start with an audit of the existing product or documentation and propose an optimal test plan aligned with your business goals and budget.
