Purpose

The purpose of the Testability Element is to implement test-specific functionality that facilitates testing, either manual or automated. There are various types of test-specific behavior, two of which are:

• "Stubs" for implementation elements that you need to simulate or have decided not to include completely in a test target.
• Elements that provide specialized interfaces or output.

Timing

Testability Element are created and modified in parallel with creating and modifying corresponding application or system implementation elements

Responsibility

The Implementer is responsible for this artifact. For additional details, see Responsibility in Artifact: Implementation Element.

The Tester role uses the testability elements to implement and execute tests.

Tailoring

See Tailoring in Artifact: Implementation Element.
