| | A [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] is an element of a [[public:99_annexes:annex-b-terms-and-definitions:t:test_sequence|Test Sequence]] that references a [[public:99_annexes:annex-b-terms-and-definitions:s:sequenced_test_object|Sequenced Test Object]] and defines occurrence-specific information and permitted progression. |
| | |
| | A [[public:99_annexes:annex-b-terms-and-definitions:t:test_sequence|Test Sequence]] is a specialization of [[public:99_annexes:annex-b-terms-and-definitions:s:sequence|Sequence]]. Each [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] identifies one position within the ordering or directed progression established by the Test Sequence. |

| | |
| | A [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] can also identify one or more permitted following [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Steps]]. Progression can depend on: |
| | |
| | * Completion of the current [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] |

| | |
| | OMG TestIF defines SequenceStep as a directed-graph node contained within a TestSequence. The SequenceStep references the SequencedTestObject represented at that position and identifies the SequenceSteps that can follow it. |
| | |
| | OMG TestIF also permits a SequenceStep to provide ArgumentValues for the input variables of its referenced SequencedTestObject. |
| | |
| | This definition preserves those characteristics while: |
| | |
| | * Defining [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] as an element of a [[public:99_annexes:annex-b-terms-and-definitions:t:test_sequence|Test Sequence]] |
| | * Relating [[public:99_annexes:annex-b-terms-and-definitions:t:test_sequence|Test Sequence]] to the general concept of [[public:99_annexes:annex-b-terms-and-definitions:s:sequence|Sequence]] |
| | * Separating permitted progression from the [[public:99_annexes:annex-b-terms-and-definitions:e:execution_path|Execution Path]] that actually occurs |
| | * Remaining independent of a particular graph-storage or implementation technology |
| | |
| | ===== Note ===== |
| | |
| | A [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] differs from a [[public:99_annexes:annex-b-terms-and-definitions:s:sequence|Sequence]]: |
| | |
| | * A Sequence defines an ordered or directed arrangement of elements and the progression relationships among them |
| | * A Sequence Step is one element within a Test Sequence |
| | |
| | A [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] differs from a [[public:99_annexes:annex-b-terms-and-definitions:t:test_sequence|Test Sequence]]: |
| | |
| | * A Test Sequence defines the overall ordering and permitted progression |
| | * A Sequence Step identifies one position and defined occurrence within that progression |
| | |
| | A [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] differs from a [[public:99_annexes:annex-b-terms-and-definitions:t:test_step|Test Step]]: |
| | |
| | * A Test Step specifies a reusable test action or [[public:99_annexes:annex-b-terms-and-definitions:v:validation|Validation]] |
| | * A Sequence Step identifies an occurrence of a Sequenced Test Object within a Test Sequence |
| | |
| | A [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] can reference a Test Step, but the Sequence Step and Test Step remain separate TestIF objects. |
| | |
| | The same Test Step can occur at multiple positions within one [[public:99_annexes:annex-b-terms-and-definitions:t:test_sequence|Test Sequence]]. Each occurrence uses a separate [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]]. |
| | |
| | A [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] differs from a [[public:99_annexes:annex-b-terms-and-definitions:s:sequenced_test_object|Sequenced Test Object]]: |
| | |
| | * A Sequenced Test Object defines reusable test content |
| | * A Sequence Step identifies how that content participates at one position within a Test Sequence |
| | |
| | The same [[public:99_annexes:annex-b-terms-and-definitions:s:sequenced_test_object|Sequenced Test Object]] can participate in: |
| | |
| | * Multiple [[public:99_annexes:annex-b-terms-and-definitions:t:test_sequence|Test Sequences]] |
| | * Multiple positions within one Test Sequence |
| | * Multiple branches within one Test Sequence |
| | * Multiple [[public:99_annexes:annex-b-terms-and-definitions:t:test_run|Test Runs]] |
| | |
| | Each [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] can provide different: |
| | |
| | * Test Argument Values |
| | * Expected Results |
| | * Starting Conditions |
| | * Timing Conditions |
| | * Progression conditions |
| | * Error-handling progression |
| | * Other occurrence-specific information |
| | |
| | A [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] does not copy or redefine the referenced [[public:99_annexes:annex-b-terms-and-definitions:s:sequenced_test_object|Sequenced Test Object]]. It supplies or references the information needed to use that object at a particular position. |
| | |
| | A [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] differs from an [[public:99_annexes:annex-b-terms-and-definitions:e:execution_path|Execution Path]]: |
| | |
| | * A Sequence Step defines a potential occurrence and permitted progression within a Test Sequence |
| | * An Execution Path identifies which Sequence Steps occurred and how progression actually proceeded during Test Execution |
| | |
| | A [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] can remain unperformed when: |
| | |
| | * [[public:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]] follows another conditional branch |
| | * A preceding Sequence Step fails |
| | * A [[public:99_annexes:annex-b-terms-and-definitions:t:timeout|Timeout]] causes error-handling progression |
| | * Test Execution terminates before reaching the Sequence Step |
| | * An authorized [[public:99_annexes:annex-b-terms-and-definitions:a:actor|Actor]] cancels the Test Run |
| | |
| | Multiple initial [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Steps]] can define parallel starting paths. |
| | |
| | Multiple following [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Steps]] can define: |
| | |
| | * Parallel progression |
| | * Conditional progression |
| | * Alternative progression |
| | * Error-handling progression |
| | |
| | The [[public:99_annexes:annex-b-terms-and-definitions:t:test_sequence|Test Sequence]] provides sufficient progression information to distinguish parallel progression from conditional or alternative progression. |
| | |
| | A [[public:99_annexes:annex-b-terms-and-definitions:t:test_result|Test Result]] can reference both: |
| | |
| | * The [[public:99_annexes:annex-b-terms-and-definitions:s:sequenced_test_object|Sequenced Test Object]] whose performance produced the outcome |
| | * The [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] that identifies the particular occurrence of that Sequenced Test Object |
| | |
| | This dual reference distinguishes Test Results produced by separate occurrences of the same Sequenced Test Object. |
| | |
| | ===== Example ===== |
| | |
| | A reusable [[public:99_annexes:annex-b-terms-and-definitions:t:test_step|Test Step]] submits a proposed transaction to a [[public:99_annexes:annex-b-terms-and-definitions:n:node|Node]]. |
| | |
| | A [[public:99_annexes:annex-b-terms-and-definitions:t:test_sequence|Test Sequence]] contains three [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Steps]] that reference the same Test Step: |
| | |
| | * Sequence Step ''SS-01'' supplies the [[public:99_annexes:annex-b-terms-and-definitions:e:endpoint|Endpoint]] and identity of Node A |
| | * Sequence Step ''SS-02'' supplies the Endpoint and identity of Node B |
| | * Sequence Step ''SS-03'' supplies the Endpoint and identity of Node C |
| | |
| | Each [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Step]] supplies occurrence-specific [[public:99_annexes:annex-b-terms-and-definitions:t:test_argument_value|Test Argument Values]] while reusing the same Test Step. |
| | |
| | During [[public:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]], the [[public:99_annexes:annex-b-terms-and-definitions:t:test_run|Test Run]] records: |
| | |
| | * Whether each Sequence Step occurred |
| | * The Test Argument Values used for each occurrence |
| | * The Starting Conditions applicable to each occurrence |
| | * The Timing Conditions applicable to each occurrence |
| | * The start time and completion time of each occurrence |
| | * The Test Result produced by each occurrence |
| | * The Verdict assigned to each Test Result |
| | * The [[public:99_annexes:annex-b-terms-and-definitions:e:execution_path|Execution Path]] followed |
| | * The supporting [[public:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] |
| | |
| | Although all three [[public:99_annexes:annex-b-terms-and-definitions:s:sequence_step|Sequence Steps]] reference the same [[public:99_annexes:annex-b-terms-and-definitions:t:test_step|Test Step]], each Test Result remains traceable to the particular Node and Sequence Step that produced it. |
