 +
 +===== Discussion =====
 +
 +A Test Environment identifies the configured Test Items, resources, conditions, and controls within which a test is executed.
 +
 +A Test Environment establishes the execution context required by a Test Definition. The Test Environment can identify:
 +
 +  * The System Under Test
 +  * Supporting Test Items
 +  * Nodes
 +  * Node Sets
 +  * Deployment Targets
 +  * Computing resources
 +  * Storage resources
 +  * Network topology
 +  * Communication paths
 +  * Software
 +  * Configuration settings
 +  * Test data
 +  * Credentials and authorization references
 +  * Security controls
 +  * Operational conditions
 +  * State conditions
 +  * Time conditions
 +  * Observation points
 +  * Measurement facilities
 +  * Evidence-collection facilities
 +  * Applicable Governance Policies
 +
 +A Test Environment can reference reusable environment definitions, Node Profiles, Deployment Target records, Test Items, and other controlled artifacts.
 +
 +A Test Environment can exist within a:
 +
 +  * [[public:99_annexes:annex-b-terms-and-definitions:c:connected_environment|Connected Environment]]
 +  * [[public:99_annexes:annex-b-terms-and-definitions:d:disconnected_environment|Disconnected Environment]]
 +  * [[public:99_annexes:annex-b-terms-and-definitions:a:air-gapped_environment|Air-Gapped Environment]]
 +
 +The Test Environment definition identifies the required configuration. A realized Test Environment identifies the resources and conditions actually used for a Test Run.
 +
 +The distinction permits an evaluator to compare the required Test Environment with the realized Test Environment and determine whether the Test Run occurred under the required conditions.
 +
 +===== Definition =====
 +
 +//configured combination of Test Items, resources, conditions, and controls within which a test is executed//
 +
 +===== Source =====
 +
 +Adapted from:
 +
 +  * [[https://www.omg.org/spec/TestIF/1.0/Beta3/PDF|OMG Test Information Interchange Format (TestIF), Version 1.0 Beta 3, Section 7.3.6, TestEnvironment]]
 +  * [[https://www.omgwiki.org/dido/doku.php?id=dido:public:te|DIDO Test Environment System Description, Version 0.2]]
 +  * [[public:99_annexes:annex-b-terms-and-definitions:d:dido-te|Distributed Immutable Data Object Test Environment (DIDO-TE)]]
 +  * DIDO-TE draft Requirements Register
 +  * United States Patent Application Publication US 2022/0237111 A1, Distributed Immutable Data Object Testing
 +  * United States Patent US 12,086,057 B2, Distributed Immutable Data Object Testing
 +
 +OMG TestIF describes a Test Environment as a Test Object that identifies the system configuration necessary to execute a test. The DIDO-TE definition extends the configuration concept to identify the Test Items, resources, conditions, and controls required for reproducible testing and validation.
 +
 +===== Note =====
 +
 +A Test Environment is not the same as [[public:99_annexes:annex-b-terms-and-definitions:d:dido-te|DIDO-TE]].
 +
 +DIDO-TE identifies the governed testing system. A Test Environment identifies a configured execution context managed or used by that system.
 +
 +One DIDO-TE implementation can manage multiple Test Environments.
 +
 +A Test Environment does not necessarily contain only virtual resources. A Test Environment can include:
 +
 +  * Physical Nodes
 +  * Virtual Nodes
 +  * Containers
 +  * Simulated Nodes
 +  * Emulated Nodes
 +  * External systems
 +  * Cloud resources
 +  * On-premises resources
 +  * Test instruments
 +  * Human-operated Test Items
 +
 +A Test Environment differs from a Deployment Target:
 +
 +  * A [[public:99_annexes:annex-b-terms-and-definitions:d:deployment_target|Deployment Target]] identifies a specific configured destination to which a Deployment can deliver an Infrastructure Environment
 +  * A Test Environment identifies the complete configured context within which a test is executed
 +
 +A Test Environment can use one or more Deployment Targets.
 +
 +A Test Environment definition does not demonstrate that the required configuration existed during a Test Run. Test Evidence must identify the realized configuration and applicable execution conditions.
 +
 +===== Example =====
 +
 +A Test Environment for evaluating a DIDO node implementation identifies:
 +
 +  * Four validated reference Nodes
 +  * One changed Node
 +  * The applicable Node Profiles
 +  * The selected Deployment Targets
 +  * The virtual network topology
 +  * The permitted communication paths
 +  * The initial DIDO state
 +  * The required clock conditions
 +  * The Test Data
 +  * The observation points
 +  * The Evidence-collection facilities
 +  * The applicable Governance Policies
 +  * The security and authorization controls
 +
 +DIDO-TE realizes the Test Environment before initiating the Test Run. The Test Evidence records the resources, configurations, versions, and conditions actually present during execution.
