Functional testing services that cover it all

Our company delivers the full scope of functional testing services, including:

Smoke testing

The very first step of the testing process, this one is to make sure the most important features work well, before proceeding with further testing.

Interface testing

We test the user interface functionality to check how fully and correctly it meets the requirements.

Requirements-based testing

We design a precise set of test cases based on the software requirements that we analyze and validate.

Integration testing

We detect defects occurring in the interfaces as well as in the functioning of integrated components or systems as a whole.


Exploratory testing

We extend the test coverage by going beyond the predefined test suite, using cognitive thinking and clearly understanding particular software specifics and end users’ behavior.

System testing

We carry out functional system testing for all of the integrated components to evaluate how the system’s behavior corresponds to the specification.

Regression testing

We assure the changes made to the system haven’t affected its flawlessly working functionality.

Acceptance testing

We ascertain that consumers can use the software to effectively perform the tasks for which the software was built.
