How to Sort Software Requirements to Verify Them Effectively?
Professional test engineers insist on verifying the software requirements specification before beginning to write code and plan functional testing, usability testing, security testing and other testing types.
Checking of application requirements has a number of peculiarities. It is an important element of quality assurance, because incomplete, incorrect or ambiguous requirements lead to defects in the program code, finding and correcting which take some time and efforts.
Experts in manual and automated testing advise to sort the application requirements in order to efficiently discover the typical errors.
It is Recommended Dividing the Tested Requirements Into:
- clear and distinct requirements that must be implemented in the program code;
- unspecified requirements that do not give clear information or can be interpreted differently;
- assumed requirements; these are requirements imagined by the designers, but not written in the specification.
The last two groups must be discussed and clarified with the designers and clients.
There are requirements that are to be implemented in late phases of the development process; this condition must be mentioned in their description. The developers and testers should have clear understanding of what requirements should be implemented at every development phase.
If all the mentioned points are discussed and correctly understood by the development team and experts in mobile testing, desktop testing or web site testing, the project is more effective and fewer software bugs are made.
