Understanding Nexial Test Artifact

Here is the hierarchy of automation, in Nexial-speak:

Test Plan                                  (commonly found in {PROJECT}/artifact/plan)
+-- (1 or more) Test Script                (commonly found in {PROJECT}/artifact/script)
    +-- (1 or more) Iteration              (defined via nexial.scope.iteration System Variable)
        +-- (1 or more) Scenario           (synonymous to worksheet in test script file)
            +-- (1 or more) Activity       (a sequence of related test step)
                +-- (1 or more) Test Step  (synonymous to command, which is either an action or validation)

As shown above, an “Activity” is a sequence of test steps, a “Scenario” is a series of “Activity”, an Iteration is a group of “Scenarios”, and so forth. From script development perspective, one can organize at different level of abstraction to improve readability and reusability.
