API Testing


Functional Testing

Black box testing that helps verify whether the code function is compliant with requirements and a web/mobile app works properly and satisfies user needs. Functional testing implies ignoring the internal parts of your web/mobile app and focusing on the output generation.

Unit Testing

White box testing that aims to verify that the implemented unit is producing expected output against given input. Typically applied for small units of code with individual functions.

Integration Testing

We combine a group of software components to produce output, and then we assess the interaction between software and hardware. For example, we can verify this way whether the payment system was integrated properly into the software or not.

Performance Testing

Allows us to measure how your web or mobile application meets performance criteria (including speed and reliability), compare several systems to define which perform better and detect general performance failures.

Regression Testing

Performed to protect your application against further failures and avoid any regressions caused by changes deployed to the functional or non-functional areas of a system, such as patches, enhancement or configuration/environment changes.

Security Testing

We perform security testing to make sure your software architecture, web or mobile app are well protected against phishing, cyber-fraud, DDoS, malware, adware and other threats that can kill your product.
