====== ENV-001h — Define Environmental Constraints ======

[[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 environmental [[dido:99_annexes:annex-b-terms-and-definitions:c:constraint|Constraint]] applicable to a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]] or record that no environmental Constraint applies 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 applicable environmental [[dido:99_annexes:annex-b-terms-and-definitions:c:constraint|Constraints]] establishes the physical, virtual, operational, jurisdictional, or connectivity conditions governing a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]].

The defined Constraints support validation of the instantiated Test Environment, reproduction of the conditions under which a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]] occurred, and assessment of whether an environmental difference influenced a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_result|Test Result]].

An explicit determination that no environmental Constraint applies 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:c:constraint|Constraint]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]]

===== Verification =====

Verification confirms that:

  * Each Test Environment defines every applicable environmental Constraint.
  * Each defined environmental Constraint identifies the condition or property it governs.
  * The instantiated Test Environment satisfies each applicable environmental Constraint.
  * A Test Environment without an applicable environmental Constraint records the determination and its basis.
  * A missing, undefined, or unsatisfied applicable environmental Constraint constitutes nonconformance with this requirement.

Verification includes:

  * Inspection of the controlled information for each Test Environment
  * Inspection of the defined environmental Constraints
  * Inspection or measurement of the conditions present in the instantiated Test Environment
  * Comparison of the observed conditions with the defined environmental Constraints
  * Inspection of recorded determinations that no environmental Constraint applies
  * Inspection of the basis recorded for each such determination
  * A negative assessment using a Test Environment that violates an applicable environmental Constraint
  * Confirmation that the negative assessment produces a nonconformance result
