Functional testing is considering the specified behavior and is based on an analysis of functionality specifications of a component of the system or the whole system itself.
Functional tests are using system functions as a basis and can be performed at all testing levels (component testing, integration tests, system level and stage of acceptance). Commonly, these functions are described in requirements, functional specifications, or in precedents for using the system (use cases).
Testing of the functionality can be performed according to such aspects as:
- requirements
- business processes
Testing in the field of “requirements” make use of the functional requirements specification of the system as a basis to design testing environment (Test Cases). In such case, the list of testing objects is to be drawn up, it is also necessary to prioritize requirements according to the risks (if it was not done in the list of requirements), because it will become a basis for prioritizing Test Cases. This program will help you to stay highly focused on the task and will not let you miss …
