====== MO-006b — Infrastructure-Independent Testing ======

[[dido:03-dido-te:99-annexes:annex-c-requirements:01-mission-objectives:mo-006:start|Go to MO-006 — Application-Independent and Infrastructure-Independent Testing]]

===== Statement =====

[[dido:99_annexes:annex-b-terms-and-definitions:d:dido-te|DIDO-TE]] SHALL preserve [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure_independence|Infrastructure Independence]] when testing across different [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure|Infrastructures]].

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

MO-006b derives from [[dido:03-dido-te:99-annexes:annex-c-requirements:01-mission-objectives:mo-006:start|MO-006 — Application-Independent and Infrastructure-Independent Testing]].

MO-006b specifies the infrastructure-independent portion of MO-006.

===== Rationale =====

Infrastructure Independence separates the governing test from the design, implementation, provider, platform, and deployment choices associated with particular Infrastructure.

This separation supports consistent evaluation across different Infrastructure without allowing infrastructure-specific assumptions to change the testing intent or favour a particular Infrastructure implementation, platform, or provider.

Infrastructure-specific adaptations remain appropriate when execution requires them. Such adaptations preserve the governing:

  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_definition|Test Definition]]
  * Evaluated characteristics
  * Evaluation method
  * [[dido:99_annexes:annex-b-terms-and-definitions:a:acceptance_criteria|Acceptance Criteria]]
  * Required outcomes
  * [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] obligations
  * [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]]

Infrastructure Independence does not imply infrastructure-neutral results. Infrastructure characteristics affect observed results, including:

  * [[dido:99_annexes:annex-b-terms-and-definitions:p:performance_efficiency|Performance Efficiency]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:r:reliability|Reliability]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:o:operational_stability|Operational Stability]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:r:resource_consumption|Resource Consumption]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:s:storage_consumption|Storage Consumption]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:e:energy_consumption|Energy Consumption]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:c:cost|Cost]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:s:scalability|Scalability]]

Infrastructure-independent testing identifies and records relevant Infrastructure characteristics so the evaluation distinguishes Infrastructure effects from changes to the governing test.

===== Applies To =====

MO-006b applies to:

  * DIDO-TE
  * Test Definitions
  * Infrastructure
  * Infrastructure-specific test adaptations
  * Evaluation methods
  * Acceptance Criteria
  * Evidence
  * Traceability

===== Verification =====

Verification confirms that:

  - DIDO-TE applies the governing Test Definition across different Infrastructure
  - The governing testing intent does not depend on the design, implementation, provider, platform, or selection of particular Infrastructure
  - The evaluated characteristics remain consistent across the tested Infrastructure
  - The evaluation method remains consistent across the tested Infrastructure
  - The Acceptance Criteria remain consistent across the tested Infrastructure
  - Infrastructure-specific adaptations preserve the Test Definition, evaluated characteristics, evaluation method, Acceptance Criteria, required outcomes, Evidence obligations, and Traceability
  - DIDO-TE identifies and records each Infrastructure-specific adaptation
  - DIDO-TE identifies and records the Infrastructure characteristics relevant to interpreting the Test Results
  - The Evidence distinguishes Infrastructure effects from changes to the governing test
