 +===== Statement =====
 +
 +The [[dido:99_annexes:annex-b-terms-and-definitions:d:dido-te|DIDO-TE]] SHALL emulate each participating [[dido:99_annexes:annex-b-terms-and-definitions:n:node|Node]] specified by the applicable [[dido:99_annexes:annex-b-terms-and-definitions:t:test_definition|Test Definition]].
 +

 +
 +===== Rationale =====
 +
 +A distributed system depends on the identities, roles, interfaces, states, capabilities, and behaviours of its participating Nodes.
 +
 +A participating Node may comprise the actual implementation, a virtualised instance, a simulator, a stub, a service double, or another controlled representation. The selected representation must exhibit the behaviour required by the Test Definition for the applicable Test Execution.
 +
 +An incorrectly represented Node may alter communication, coordination, failure handling, recovery, security, or resulting system behaviour. The Test Definition therefore specifies the required representation and fidelity criteria for each participating Node.
 +
 +===== 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 participating Node.
 +  * Each participating Node has a unique identity.
 +  * The Test Definition specifies the role, interfaces, initial state, configuration, capabilities, dependencies, and required behaviour of each participating Node.
 +  * The Test Definition identifies the representation used for each participating Node.
 +  * The Test Definition specifies the applicable fidelity criteria for each Node representation.
 +  * The DIDO-TE instantiates each participating Node using its specified representation.
 +  * Each participating Node occupies the location and relationships specified by the distributed topology.
 +  * Each participating Node exposes the specified interfaces.
 +  * Each participating Node assumes the specified initial state before Test Execution.
 +  * Each participating Node exhibits the specified behaviour during Test Execution.
 +  * The DIDO-TE distinguishes an actual implementation from an emulated representation in the resulting records.
 +  * The DIDO-TE detects a missing, additional, substituted, incorrectly configured, incorrectly located, or unresponsive participating Node.
 +  * The DIDO-TE records Node identities, representations, configurations, states, interactions, 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 participating Node, its representation, the Test Definition, Test Execution, Evidence, and [[dido:99_annexes:annex-b-terms-and-definitions:t:test_result|Test Results]].
 +  * A missing, additional, incorrectly represented, incorrectly configured, unsupported, or untraceable mandatory participating Node constitutes nonconformance with this requirement.
 +
 +Verification includes:
 +
 +  * Inspection of the participating Nodes identified by the Test Definition
 +  * Inspection of Node identities, roles, representations, interfaces, configurations, states, capabilities, and dependencies
 +  * Comparison of specified and instantiated participating Nodes
 +  * Observation of participating Node behaviour during Test Execution
 +  * A negative assessment with a missing or substituted participating Node
 +  * A negative assessment with an incorrect Node configuration, state, interface, or behaviour
 +  * Confirmation that the DIDO-TE detects and records each Node deviation
 +  * Inspection of participating-Node Evidence and Traceability records
 +  * Confirmation that each mandatory Node deviation produces a nonconformance result
