It is wise to proceed to mobile testing, desktop testing and web site testing as early as possible.

Often project managers involve a software testing company only when the development process begins, and some parts of the application are ready. But experts in manual and automated testing recommend beginning a testing process from testing the application requirements. This way a lot of errors can be eliminated before their implementation in the program code.

It is common knowledge that the most cost effective approach to software development is to get rid of defects before their appearance in the program.

Software Product Requirements Must:

  • describe all the assumed functions and features of the elaborated application;
  • be unequivocal; all the team members should have the same understanding of the requirements;
  • inform what the application is not supposed to do.

Test engineers study the software requirements, discuss them, clarify what is missing or equivocal and ask the designers for explanation. For example, if a requirement is understood differently be different team members, or when the requirement is not specified. This way every requirement is verified and edited, if necessary.

Key to efficient software testing and development is in well thought out and carefully tested requirements.
