====== ENV-002c — Instantiate Included Nodes ======

[[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 instantiate each [[dido:99_annexes:annex-b-terms-and-definitions:n:node|Node]] included in 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 =====

Instantiating each included [[dido:99_annexes:annex-b-terms-and-definitions:n:node|Node]] establishes the operational participants required by a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]].

The instantiated Nodes perform the information-processing, communication, observation, control, or support functions required during [[dido:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]].

Establishing correspondence between each defined Node and its instantiated state supports controlled execution, [[dido:99_annexes:annex-b-terms-and-definitions:r:reproducibility|Reproducibility]], and assessment of whether a Node difference influenced a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_result|Test Result]].

===== 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_execution|Test Execution]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:c:configuration|Configuration]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:b:baseline|Baseline]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:d:deployment_target|Deployment Target]]

===== Verification =====

Verification confirms that:

  * The DIDO-TE instantiates every Node included in the Test Environment.
  * Each instantiated Node corresponds to a Node identified by the controlled Test Environment information.
  * Each instantiated Node has the specified version, Baseline, Configuration, and Deployment Target.
  * Each instantiated Node enters its required initial lifecycle state before Test Execution.
  * The DIDO-TE maintains [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] between each defined Node and its instantiated state.
  * A missing, incorrect, or untraceable Node instance constitutes nonconformance with this requirement.

Verification includes:

  * Inspection of the Nodes identified for the Test Environment
  * Inspection of each instantiated Node
  * Comparison of each instantiated Node with its controlled definition
  * Inspection of the version, Baseline, Configuration, Deployment Target, and initial lifecycle state of each instantiated Node
  * Inspection of Traceability records connecting each defined Node to its instantiated state
  * A negative assessment using a missing, incorrect, or untraceable Node instance
  * Confirmation that the negative assessment produces a nonconformance result
