====== ENV-001f — Define Communication Relationships ======

[[dido:03-dido-te:99-annexes:annex-c-requirements:03-functional-requirements:03-01-test-environment-requirements:env-001-define-test-environment:start|Go to ENV-001 — Define Test Environment]]

===== Statement =====

The [[dido:99_annexes:annex-b-terms-and-definitions:d:dido-te|DIDO-TE]] SHALL define each communication relationship required among the elements included in a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]] or record that no communication relationship is required and provide the basis for the determination.

===== 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 =====

Defining the required communication relationships establishes how the elements included in a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]] exchange information during a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]].

The defined relationships provide the information required to configure connectivity, validate the instantiated Test Environment, reproduce its communication structure, and determine whether an unexpected communication path influenced a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_result|Test Result]].

An explicit determination that no communication relationship is required distinguishes an intentional condition from missing information.

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

  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:n:node|Node]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_object|Test Object]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_resource|Test Resource]]

===== Verification =====

Verification confirms that:

  * Each Test Environment defines every required communication relationship among its included elements.
  * Each defined communication relationship identifies the participating elements.
  * Each communication relationship present in the instantiated Test Environment corresponds to a defined communication relationship.
  * A Test Environment requiring no communication relationship records the determination and its basis.
  * An undefined required communication relationship constitutes nonconformance with this requirement.

Verification includes:

  * Inspection of the controlled information for each Test Environment
  * Inspection of the defined communication relationships
  * Inspection of the communication relationships present in the instantiated Test Environment
  * Comparison of the defined relationships with the relationships present in the instantiated Test Environment
  * Inspection of recorded determinations that no communication relationship is required
  * Inspection of the basis recorded for each such determination
  * A negative assessment using an undefined or unexpected communication relationship
  * Confirmation that the negative assessment produces a nonconformance result
