Functional testing is what we might rationally think of as the most fundamental kind of software testing. When people build software, they build it to perform a whole array of tasks. So QArtrock is here to evaluate whether or not the software performs those tasks, for which it was designed.
Functional testing deals with how applications functions, or, in other words, its relation to the users and especially to the rest of the system.
To make functional testing more efficient, we perform requirements-based checking under the prioritized criteria and start testing the most critical features.
