====== ENV-002f — Establish Communication Relationships ======

[[dido:03-dido-te:99-annexes:annex-c-requirements:03-functional-requirements:03-01-test-environment-requirements:env-002-configure-test-environment:start|Go to ENV-002 — Configure Test Environment]]

===== Statement =====

The [[dido:99_annexes:annex-b-terms-and-definitions:d:dido-te|DIDO-TE]] SHALL establish each communication relationship specified for a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]] before [[dido:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]].

===== Derived From =====

  * [[dido:03-dido-te:99-annexes:annex-b-references:dte-005|[DTE5] DIDO-TE Requirements Register]], source requirement identifier and obligation to be assigned
  * [[dido:03-dido-te:99-annexes:annex-b-references:dte-006|[DTE6] Structured Information Processing Reference Architecture (SIP-RA)]]
  * [[dido:03-dido-te:99-annexes:annex-b-references:dte-007|[DTE7] Federated Data Interpretation Systems Reference Architecture (FDIS-RA)]]

===== Rationale =====

Establishing each specified communication relationship provides the controlled information paths required among the [[dido:99_annexes:annex-b-terms-and-definitions:t:test_object|Test Objects]], [[dido:99_annexes:annex-b-terms-and-definitions:n:node|Nodes]], [[dido:99_annexes:annex-b-terms-and-definitions:t:test_resource|Test Resources]], and supporting services within a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]].

Each communication relationship determines the participating endpoints and the applicable direction, protocol, interface, data exchange, addressing, quality, and security conditions.

Establishing and verifying these relationships before [[dido:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]] prevents missing, incorrect, or unintended communication paths from affecting execution or the resulting [[dido:99_annexes:annex-b-terms-and-definitions:t:test_result|Test Results]].

===== Applies To =====

  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_object|Test Object]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:n:node|Node]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_resource|Test Resource]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:c:configuration|Configuration]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:c:constraint|Constraint]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]]

===== Verification =====

Verification confirms that:

  * The DIDO-TE establishes every communication relationship specified for the Test Environment.
  * Each established communication relationship connects the specified participating endpoints.
  * Each established communication relationship has the specified direction, protocol, interface, addressing, data exchange, and quality characteristics, when applicable.
  * Each established communication relationship satisfies its applicable security and environmental Constraints.
  * The configured Test Environment excludes communication relationships prohibited by its controlled information.
  * The DIDO-TE records each established communication relationship as part of the resulting Test Environment Configuration.
  * The DIDO-TE maintains [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] between each specified communication relationship and its configured instance.
  * A missing, incorrect, prohibited, or untraceable communication relationship constitutes nonconformance with this requirement.

Verification includes:

  * Inspection of the communication relationships specified for the Test Environment
  * Inspection of the endpoints and characteristics of each established communication relationship
  * Testing of communication across each required relationship
  * Testing for the absence of each prohibited communication relationship
  * Comparison of the observed communication relationships with the controlled Test Environment information
  * Inspection of the resulting Test Environment Configuration
  * Inspection of Traceability records connecting each specified communication relationship to its configured instance
  * A negative assessment using a missing, incorrect, prohibited, or untraceable communication relationship
  * Confirmation that the negative assessment produces a nonconformance result
