How many types of Actions are there in QTP?
There are three kinds of actions: non-reusable action—an action that can be called only in the test with which it is stored, and can be called only once. reusable action—an action that can be called multiple times by the test with which it is stored (the local test) as well as by other tests. external action—a reusable action stored with another test. External actions are read-only in the calling test, but you can choose to use a local, editable copy of the Data Table information for the external action.
