Software testing · QA
Software testing and QA, from the first requirement to release.
Red Giant tests web and mobile applications for businesses in Vietnam and abroad. Our QA engineers join at the requirement stage, so problems are caught in design, not found by your users after launch.
Testing services
Every kind of testing your release needs
Manual testing
Engineers walk through every critical path the way your users will, on real browsers and devices, and log each defect with steps to reproduce.
Test automation
Maintainable end-to-end and API suites in Playwright, Cypress or Selenium, wired into your CI so every build is checked.
Regression testing
Before each release we re-run what already worked, so a new feature doesn’t quietly break an old one.
Exploratory testing
Time-boxed sessions that go off-script to find the bugs test cases don’t predict.
Performance and load testing
We measure response times under realistic load and find the point where your system slows down.
Mobile device testing
iOS and Android apps and responsive sites checked on the screen sizes and OS versions your users have.
Security checks
Access control, data exposure and common web vulnerabilities checked before they reach production.
Release integration testing
The release candidate tested as a whole, with its integrations, in an environment that mirrors production.
User acceptance testing (UAT)
We prepare UAT scenarios with your team and support them through sign-off against the agreed criteria.
Post-deployment checks
Right after you go live we verify the critical paths in production and report within 2 hours of your go signal.

AI-built apps
Built your app with AI coding tools?
We run a dedicated QA service for apps built with Claude Code, Cursor, Lovable and similar tools: the same process, focused on where those apps usually break.
