Actions help divide your test into logical units, specific activities that you perform in your application.

A test is made up of calls to actions. When you create a new test, it contains a call to a single action or create tests that call multiple actions by inserting calls to them, to make the design more modular and efficient tests.

• reusable action—an action that can be called multiple times by the test with which is stored in 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. They can be modified only in the test with which they are stored.

• Non-resuable-actions —an action that can be called only in the test with which it is stored, and can be called only once.
