===== Discussion =====

A Test Case specifies the [[dido:99_annexes:annex-b-terms-and-definitions:t:test_step|Test Steps]] and [[dido:99_annexes:annex-b-terms-and-definitions:e:expected_result|Expected Results]] used to verify a defined subject.

As a [[dido:99_annexes:annex-b-terms-and-definitions:s:sequenced_test_object|Sequenced Test Object]], a Test Case can contain or reference a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_sequence|Test Sequence]]. The Test Sequence establishes the order and progression of the [[dido:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Steps]] associated with the Test Case.

A Test Case can identify:

  * Its identity
  * Its name
  * Its [[dido:99_annexes:annex-b-terms-and-definitions:t:test_purpose|Test Purpose]]
  * Its version
  * The subject being verified
  * The applicable [[dido:99_annexes:annex-b-terms-and-definitions:t:test_item|Test Items]]
  * The applicable [[dido:99_annexes:annex-b-terms-and-definitions:s:system_under_test|System Under Test]]
  * The applicable [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environments]]
  * The applicable Test Sequence
  * The applicable Test Steps
  * The applicable [[dido:99_annexes:annex-b-terms-and-definitions:t:test_executable|Test Executables]]
  * The applicable Test Arguments
  * The applicable Test Argument Values
  * The applicable Expected Results
  * The applicable entry conditions
  * The applicable completion conditions
  * The applicable evaluation criteria
  * The applicable [[dido:99_annexes:annex-b-terms-and-definitions:g:governance_policy|Governance Policies]]
  * Its [[dido:99_annexes:annex-b-terms-and-definitions:p:provenance|Provenance]]
  * Its [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]]

A Test Case can participate in one or more [[dido:99_annexes:annex-b-terms-and-definitions:t:test_set|Test Sets]].

A Test Case can reference reusable Test Steps and Test Executables without containing copies of them. Each [[dido:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] identifies the occurrence of a Test Step or Test Executable within the Test Sequence.

===== Definition =====

//[[dido:99_annexes:annex-b-terms-and-definitions:s:sequenced_test_object|Sequenced Test Object]] that specifies the [[dido:99_annexes:annex-b-terms-and-definitions:t:test_step|Test Steps]] and [[dido:99_annexes:annex-b-terms-and-definitions:e:expected_result|Expected Results]] used to verify a defined subject//

OMG TestIF defines TestCase as the set of steps necessary to verify something. TestIF permits a Test Case to contain any number of Test Steps organized through a Test Sequence.

This definition preserves the TestIF verification purpose while identifying both Test Steps and Expected Results as essential characteristics of a Test Case.

===== Note =====

Every Test Case is a [[dido:99_annexes:annex-b-terms-and-definitions:s:sequenced_test_object|Sequenced Test Object]] and therefore a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_object|Test Object]].

A Test Case differs from a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_set|Test Set]]:

  * A Test Case specifies the Test Steps and Expected Results used to verify a defined subject
  * A Test Set groups related Test Objects for a defined Test Purpose

A Test Case differs from a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_step|Test Step]]:

  * A Test Case identifies the complete verification unit
  * A Test Step identifies one action or validation performed as part of a Test Sequence

A Test Case differs from a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_executable|Test Executable]]:

  * A Test Case specifies what the Test verifies
  * A Test Executable contains or references low-level procedural or executable information used for automated [[dido:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]]

A Test Case differs from a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_result|Test Result]]:

  * A Test Case specifies the verification to perform
  * A Test Result records an outcome produced by Test Execution

A Test Case differs from a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_run|Test Run]]:

  * A Test Case specifies the verification unit
  * A Test Run records an identified execution and its Test Results

A Test Case can reference more than one [[dido:99_annexes:annex-b-terms-and-definitions:t:test_item|Test Item]]. The applicable Test Definition identifies which Test Item or collection of Test Items constitutes the subject being verified.

A change to the Test Purpose, Test Steps, Test Sequence, Expected Results, or evaluation criteria can create a new Test Case version when the change affects Test Execution, reproducibility, comparison, or validation.

===== Example =====

A [[dido:99_annexes:annex-b-terms-and-definitions:d:dido-te|DIDO-TE]] Test Case verifies that a proposed DIDO transaction produces the required successor state.

The Test Case references:

  * The applicable [[dido:99_annexes:annex-b-terms-and-definitions:t:test_item|Test Items]]
  * The applicable [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]]
  * A [[dido:99_annexes:annex-b-terms-and-definitions:t:test_sequence|Test Sequence]]
  * A Test Step that submits the transaction
  * A Test Step that observes transaction distribution
  * A Test Step that observes validation by the participating [[dido:99_annexes:annex-b-terms-and-definitions:n:node|Nodes]]
  * A Test Step that retrieves the resulting [[dido:99_annexes:annex-b-terms-and-definitions:d:dido|DIDO]] state
  * An Expected Result identifying the required successor state

During Test Execution, the [[dido:99_annexes:annex-b-terms-and-definitions:t:test_run|Test Run]] records the Test Case version, execution context, and resulting [[dido:99_annexes:annex-b-terms-and-definitions:t:test_result|Test Results]].
