 +====== ENV-004h — Control External Dependencies ======
  
 +[[dido:03-dido-te:99-annexes:annex-c-requirements:03-functional-requirements:03-01-test-environment-requirements:env-004-provide-deterministic-test-environment:start|Go to ENV-004 — Provide Deterministic Test Environment]]
 +
 +===== Statement =====
 +
 +The [[dido:99_annexes:annex-b-terms-and-definitions:d:dido-te|DIDO-TE]] SHALL control each external dependency in accordance with the applicable [[dido:99_annexes:annex-b-terms-and-definitions:t:test_definition|Test Definition]].
 +
 +===== Derived From =====
 +
 +  * [[dido:03-dido-te:99-annexes:annex-c-requirements:03-functional-requirements:03-01-test-environment-requirements:env-004-provide-deterministic-test-environment:start|ENV-004 — Provide Deterministic Test Environment]]
 +  * [[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 =====
 +
 +A [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]] may rely on services, systems, data sources, identity providers, repositories, networks, devices, infrastructure, or organisations outside its direct boundary.
 +
 +A change in an external dependency may alter the behaviour of the [[dido:99_annexes:annex-b-terms-and-definitions:t:test_object|Test Object]] or the resulting [[dido:99_annexes:annex-b-terms-and-definitions:t:test_result|Test Results]].
 +
 +The applicable Test Definition identifies each external dependency and specifies its required identity, version, interface, state, response behaviour, availability, and permitted variation.
 +
 +Control includes isolation, substitution, simulation, replication, version restriction, contractual restriction, or measurement and recording, as specified by the Test Definition.
 +
 +===== 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: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:e:evidence|Evidence]]
 +
 +===== Verification =====
 +
 +Verification confirms that:
 +
 +  * The applicable Test Definition identifies each external dependency that influences the Test Execution.
 +  * Each external dependency has a unique identity.
 +  * Each external dependency has a defined provider and boundary.
 +  * The Test Definition specifies the required version, interface, state, response behaviour, availability, and permitted variation for each external dependency.
 +  * The DIDO-TE applies the specified control method to each external dependency.
 +  * The DIDO-TE verifies the state of each external dependency before Test Execution.
 +  * The DIDO-TE monitors each applicable external dependency during Test Execution.
 +  * The DIDO-TE detects an unavailable, substituted, altered, incompatible, or unauthorised external dependency.
 +  * The DIDO-TE records dependency identities, versions, states, interactions, changes, failures, and detected deviations as [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]].
 +  * The DIDO-TE maintains [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] among each external dependency, the Test Definition, the Test Execution, the Evidence, and the Test Results.
 +  * An unidentified, uncontrolled, unavailable, incompatible, altered, or untraceable external dependency constitutes nonconformance with this requirement.
 +
 +Verification includes:
 +
 +  * Inspection of the external dependencies identified by the Test Definition
 +  * Inspection of dependency identities, providers, boundaries, versions, interfaces, states, and control methods
 +  * Observation of external dependency control during Test Execution
 +  * Comparison of required and observed dependency conditions
 +  * A negative assessment using an unavailable or incompatible external dependency
 +  * A negative assessment using an unauthorised dependency substitution
 +  * Confirmation that the DIDO-TE detects and records each deviation
 +  * Inspection of dependency Evidence and Traceability records
 +  * Confirmation that each negative assessment produces a nonconformance result
