QA – quality assurance and software testing

Quality Assurance (QA) is the systematic process of making sure software does what it should – reliably, quickly and securely – on all devices and under real load. We offer QA as part of our projects and as a standalone service for software developed by other teams.

Types of testing

Functional testing

We check every scenario from the user’s point of view – registration, ordering, payment, reports, access rights – including the edge cases and error cases developers often miss.

Regression testing

With every new version we check that the existing features still work. This is where automation saves the most time and money.

Automated tests

We build a suite of automated tests (unit, integration and end-to-end) that run on every code change through CI/CD. Bugs are caught in minutes, not weeks.

Load and performance testing

We simulate hundreds and thousands of simultaneous users to find the bottleneck – before Black Friday, a campaign or a TV advert.

Security testing

Checks for vulnerabilities from the OWASP Top 10: injections, XSS, broken authentication, data leaks, weak configuration. If needed – a full penetration test.

Compatibility and mobile devices

We test on real browsers and devices – Chrome, Safari, Firefox, Edge, Android and iOS, at different screen sizes.

Accessibility (WCAG)

We check whether the site can be used by people with disabilities – with a screen reader, with the keyboard only, with zoom. The European Accessibility Act (EAA), applicable from 28 June 2025, requires certain products and services, including online stores, to be accessible.

What you get

• a test plan and test scenarios;
• detailed bug reports with steps to reproduce, screenshots and video;
• prioritisation by severity;
• automated tests that remain in your project;
• a performance report with specific recommendations;
• re-testing after the bugs are fixed.

QA as a service

For companies with ongoing development we offer a QA specialist or team on a monthly contract who joins your process – takes part in planning, tests every new feature and maintains the automated tests.
