WEB What we test
-
Websites
Functional testing of forms and checkout flows, visual checks across all resolutions and browsers, and performance under load, before your site sees its first real visitor.
-
Desktop apps
Windows and macOS: installation, upgrades and regression after every change. We also check what users should never see: edge cases and recovery from errors.
-
Mobile apps
Android and iOS on real phones: touch, gestures, rotation, network drops, low battery. An emulator doesn't know how an app behaves in your pocket. We do.
On real devices
An emulator is an approximation; a real device is the truth. We test on phones of different generations and price ranges, because not all of your users hold the latest flagship.

Why QA matters
Software history is full of expensive lessons: bugs that made it to production have cost companies millions. A few famous examples:
-
$370M
Ariane 5 (1996)
The European Space Agency rocket exploded 40 seconds after launch because of a single integer overflow in code inherited from the previous rocket.
-
$440M
Knight Capital (2012)
Old code forgotten on one of eight servers was activated during a deploy and lost 440 million dollars in 45 minutes. The firm never recovered.
-
$18M
NASA Mariner 1 (1962)
The probe to Venus was destroyed 293 seconds after launch because of a single missing hyphen in a hand-transcribed formula. The most expensive hyphen in history.

The cost of a late bug
IBM's analysis: a bug found in production costs up to a hundred times more than the same bug caught during development. That's why you test before launch, not after the first complaint.
More on why testing before launch matters in our article (in Serbian): Why a website must be tested before launch. And one bug is following you around this page right now. Scroll to the end.
