For example, you may have Test Scripts that are combinations of different actions you can perform to a record. These Test Scripts may be combinations of the addition, modification, and the deletion of a record: 1  Add, Modify, Delete (the obvious one). 2  Add, Delete, Modify. 3  Add, Delete, Add, Delete, ...4  Add, Add, Add, ...f you identify and implement these actions as separate Test Scripts and reuse them in other Test Scripts you will achieve a higher level of reuse. Another goal would be to structure your Test Scripts in such a way that a change in the target software causes a localized and controllable change in your Test Scripts.
