Functional Testing — every feature works the way your users expect

Our 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.

Overview

Bugs in production cost far more than bugs found in testing.

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.

Without functional testing, you risk:

  • ●Broken sign-up, login or checkout flows
  • ●Wrong calculations, prices or reports
  • ●Releases that break features that used to work
  • ●Poor app-store ratings and support tickets
  • ●Lost customers and revenue

FAQ

Questions before you start

What is functional testing?−

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.

Do you do manual or automated testing?+

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.

Which platforms do you test?+

Web applications on all major browsers, Android and iOS apps on real devices, APIs, and desktop applications.

Do you also check for security issues?+

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.
