+91 98183 63944Our QA engineers test every screen, workflow and integration of your web or mobile app against your requirements — on real browsers and devices. You get clear, reproducible bug reports your developers can fix fast, and a release you can ship with confidence.
Developers test what they build, but they test it the way they built it. Independent functional testing checks your app the way real users use it — every requirement, every edge case, every browser and device. We find the broken flows, wrong calculations and confusing errors before they reach your customers.

Click an area to see what we check — and an example of what we find.
Every screen, form and journey checked against your requirements.
Your web app on the browsers and screen sizes your users actually use.
Android and iOS apps tested on real devices, not just emulators.
The APIs, payment gateways and third-party services behind your app.
Making sure new releases don’t break features that already worked.
Automated test suites for the flows you run on every release.
Study your requirements, user stories and the app itself.
Write a test plan and test cases that cover every requirement.
Run the tests on agreed browsers, devices and environments.
Clear, reproducible bug reports with steps, screenshots and severity.
Verify fixes, run regression tests and sign off the release.
Every engagement is scoped to your application and release plan. Tell us what you need and we’ll send a fixed quote.
A focused round of functional testing for one release or new feature — ideal before a launch.
End-to-end functional, cross-browser, mobile and API testing of your whole application.
An ongoing QA team that tests every sprint and release alongside your developers.
“Their penetration testing methodology was thorough and aligned with OWASP standards. The final report was detailed, actionable, and easy for our developers to understand.”
“Xtreme InfoSec identified critical vulnerabilities that other vendors missed, with excellent remediation support.”
Functional testing checks that every feature of your software does what it is supposed to do — that inputs give the right outputs, and that users can complete every task without errors.
Both. We test new features manually, then automate the stable flows you run on every release (with tools such as Selenium, Playwright and Appium) to save time and cost.
Web applications on all major browsers, Android and iOS apps on real devices, APIs, and desktop applications.
Functional testing focuses on whether features work. If you also want to know whether they can be attacked, we can add web, mobile or API penetration testing to the same engagement.
