10 Software integration and testing

Individual units or modules are tested. It involves testing of source code by developers.

Individual modules are grouped together and tested. The purpose is to determine that modules are working as expected once they are integrated.

Testing is performed on the whole system by checking whether the system or application meets the requirement specification document.

u Mapping VectorCAST Features

Conclusions

Agenda

19

u What we see at most customers is a software architect or safety manager role. The person(s) in this ‘role’ owns the responsibility to define, specify, develop, monitor, and improve the software development process

u The mapping will show how various features in VectorCAST could support your software development process

u The applicability of these features to your software development process will have to be evaluated on a project by project basis
