While performing functional QA testing, we assess core system functionality and also check if the software is user-friendly. For this, we conduct basic usability checking, accessibility verification for end users and we determine and test error conditions.
To make the functional testing process flow more efficient, we perform requirements-based checking based on prioritized criteria and start by testing the most critical features. We execute functional tests applying black box methodology.
In order not to miss software logic issues and avoid redundant checking, we thoroughly examine the specifications and system requirements. By prioritizing product features and tests, we evaluate critical functionality first.
If a bug is discovered and regression testing needs to be carried out, functional testing helps to trace already executed tests and recheck system functions. This approach allows us to understand the current quality of the solution and evaluate future steps.
