In the model previously designed, you are going to create and update manually requirements, or import them from Doors or ALM Quality Center. Requirements are dragged and droped on transitions. Then requirement traceability report with generated test cases is automatically created. Model can also be filtered in order to show small pathes to cover selected requirements, and allows to generate small test campaigns covering these requirements. This kind of testing is named "Requirement based testing". by Fabrice TROLLET
