How we test web apps

Functional testing

We evaluate if a web app works correctly according to the requirements.

Compatibility testing

We check if a web application works correctly in different browsers, on different devices, and other platforms.

Usability testing

We check if a web application is convenient, easy to use, and user-friendly.

Security testing

We assess a web app’s security, the possibilities of unauthorized access and data breaches.

Integration testing

We test integration between different parts of a web app and between a web application and third-party solutions.

Data testing

We check if there are any issues with the data that are entered into and processed in a web application.

API testing

We check whether a web app works correctly with third-party APIs. If a web application has its own API, we evaluate its work as well.

Regression testing

We check whether the recent bug fixes and changes in a web app caused any disruptions in its work.

Performance testing

We assess a web app’s performance (speed, load, resource consumption, etc.).

Accessibility testing

We assess if people with disabilities can use a web app easily.

Stages of testing
