Artifact: Test Subsystem

Test Subsystem	A kind of implementation subsystem, in the implementation model, containing test-related components.
UML representation:	Package in the implementation model, stereotyped as ½test subsystem╗.
Worker:	Implementer
Optionality:	This artifact is only used if you are designing and implementing test specific functionality.
More information:	Guideline: Implementation Subsystem.

Purpose

The purpose of the test subsystem is to implement the test specific functionality to facilitate or automate tests. There are two main types of test-specific subsystems:

• Test subsystems that are "stubs" for design classes that you need to simulate or have decided not to include completely in a test target.
• Test subsystems that are drivers, facilitating the automation of test cases.

The Tester uses the test subsystems to execute the test specific functionality in testing. The test subsystem is a kind of implementation subsystem.

Properties

See Properties in Artifact: Implementation Subsystem.

Timing

Test subsystems are created and modified in parallel with creating and modifying corresponding application subsystems.

Responsibility

See Responsibility in Artifact: Implementation Subsystem.

Tailoring

See Tailoring in Artifact: Implementation Subsystem.
