===== Statement =====

Before each [[dido:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]], the [[dido:99_annexes:annex-b-terms-and-definitions:d:dido-te|DIDO-TE]] SHALL apply each applicable [[dido:99_annexes:annex-b-terms-and-definitions:c:constraint|Constraint]] to the [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]] element governed by the Constraint.

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

  * [[dido:03-dido-te:99-annexes:annex-c-requirements:03-functional-requirements:03-01-test-environment-requirements:env-003-establish-controlled-starting-state:start|ENV-003 — Establish Controlled Starting State]]

  * [[dido:03-dido-te:99-annexes:annex-b-references:dte-006|[DTE6] Structured Information Processing Reference Architecture (SIP-RA)]]

===== Rationale =====

Applying each applicable [[dido:99_annexes:annex-b-terms-and-definitions:c:constraint|Constraint]] establishes the conditions, limits, prohibitions, dependencies, and relationships governing the controlled starting state.

Constraints may govern participating [[dido:99_annexes:annex-b-terms-and-definitions:n:node|Nodes]], [[dido:99_annexes:annex-b-terms-and-definitions:t:test_object|Test Objects]], [[dido:99_annexes:annex-b-terms-and-definitions:t:test_resource|Test Resources]], [[dido:99_annexes:annex-b-terms-and-definitions:t:test_input|Test Inputs]], communication relationships, security controls, resource limits, timing, location, or other Test Environment characteristics.

Applying Constraints before Test Execution prevents a starting state that violates its governing conditions from producing invalid, misleading, or incomparable [[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_definition|Test Definition]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:c:constraint|Constraint]]
  * [[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]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_input|Test Input]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:c:configuration|Configuration]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]]

===== Verification =====

Verification confirms that:

  * The controlled descriptive information identifies each Constraint applicable to the Test Environment.
  * The controlled descriptive information identifies the Test Environment element governed by each Constraint.
  * The DIDO-TE applies each applicable Constraint before Test Execution.
  * Each governed Test Environment element satisfies its applicable Constraints.
  * The DIDO-TE detects missing, conflicting, unsatisfied, and prohibited conditions.
  * The DIDO-TE records the identity, application status, and evaluation result of each applicable Constraint.
  * The DIDO-TE maintains [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] among each Constraint, its governed Test Environment element, its evaluation result, and the applicable Test Execution.
  * A missing, incorrectly applied, conflicting, unsatisfied, or untraceable Constraint constitutes nonconformance with this requirement.

Verification includes:

  * Inspection of the controlled descriptive information identifying the applicable Constraints
  * Inspection of the Test Environment elements governed by the Constraints
  * Observation of Constraint application and evaluation
  * Confirmation that each governed Test Environment element satisfies its applicable Constraints
  * Testing for missing, conflicting, unsatisfied, and prohibited conditions
  * Inspection of Constraint identity, application-status, and evaluation records
  * Inspection of Traceability records connecting each Constraint to its governed element, evaluation result, and Test Execution
  * A negative assessment using a missing, incorrectly applied, conflicting, unsatisfied, or untraceable Constraint
  * Confirmation that the negative assessment produces a nonconformance result
