Those, who specialize in web site testing, desktop testing and mobile application testing, know that it is necessary to start a software testing process from verifying the application requirements.
Requirements must be carefully checked by test engineers as soon as they are ready. It allows to find and correct software bugs before they are implemented in the code.
Experts in manual and automated testing claim that checking of software requirements has some peculiarities.
There are 3 Common Defects of Application Requirements:
- Unspecified requirements. These are requirements that are not enough exact or do not give certain figures, for example: the application should load fast. This requirement doesn’t inform the desired speed.
- Assumed, but not documented requirements. Sometimes customers assume some functions and qualities of the program, but do not describe them in the requirements specification. Test engineers should detect such requirements, clarify and make sure they have been added to the specification.
- Ambiguous requirements. There are requirements that can be interpreted in different ways. Testers must determine what they mean and make them clear to all the project members.
A software development process is much more profitable, if the requirements are tested at the beginning. Results of functional testing, load testing, usability testing, security testing and other testing types always prove that.
