Config Add Command Step in Step Wizard

A Config Add command creates an IxLoad test configuration element.

To add a Config Add command step using the GUI scripting support:

  1. While in the Test Steps pane, add a step by choosing the Actions > Add step... command.
  2. Select a Config Add step type, click the button to validate the selection, and specify the following parameters:
    • Run Type: A Config Add step can be executed sequentially (Sequential) or in parallel (Parallel) with other steps.
    • Delay: A delay specifying by how much step start is delayed. A delay value is automatically set when the step is added using the Capture functionality.
    • Timeout: A period of time after which the step execution is considered to have timed out.
    • Ignore step: When this option is selected, the step is skipped at execution time. Selecting this option is equivalent to right-clicking a step in the Test Steps table and choosing the Exclude command from the context menu that appears.
    • Description: An optional step description can be associated with a step.
    • Click Next.

  3. Define the Conditional Execution settings as explained below.
  4. Conditional Execution settings enable you to define the system conditions a test step execution is monitored for. When such a predefined condition occurs – a step error or a step timeout – an user-defined procedure is executed and an additional action is performed. For example, on encountering a step error, you could enforce the execution of a cleanup procedure and then terminate the test.

    To monitor the step for a predefined Timeout or Error condition, select the corresponding condition, then define the associated procedure – local or shared (external) – by clicking the control of the Procedure field and selecting a procedure from the the drop-down pane that appears.

    For the selected procedure you can view its defined arguments by clicking the control of the Input Arguments field, which displays a cascading table-format pane containing the argument list. To specify the actual runtime argument(s) enter the desired values in the Current Value field(s).

    Configure an additional action by clicking into additional actions column and selecting either of the following options:

    • Continue: After performing the specified procedure, the test execution continues.
    • Exit Test: After performing the specified procedure, the test execution is terminated.
    • Click Next.

    Whenever the step execution is monitored for predefined events, an icon is displayed in the step's corresponding Events selected column entry. For information on turning on the displaying of the Events selected column refer to Customizing the Script Steps Table Layout.

  5. Specify the following command parameters:
    • Session: The Built-in Event session type.
    • Return variable: A TestComposer composite variable whose only member contains the object reference of the newly added configuration element
    • Command string: The Configuration Add command, whose parameters are configured by clicking the button, which displays the GUI shown in Figure:Config Add GUI. The following parameters are populated:
      • select: An X-Path expression that corresponds to the IxLoad configuration element that is to be added.
      • In addition to the X-Path notation, the select statement also supports the notation that is used by the IxLoad Tcl API, whereby a configuration element is specified using an expression composed of the tree path, an ":" string, and an element index. For example, the "/traffic/trafficItem[2]" expression could be rewritten using the "/traffic/trafficItem:6" specifier, which illustrates the fact that the X-Path index and the Tcl API index referencing an entity of a configuration element are not necessarily the same.

      • type: The type of the selected child element.
      • attributes: A list of space-separated attribute-value pairs to be set on the configuration object that is being created. If the attributes are multi-value, the multi-value editor can be used. For information on Multi-value editor refer to Support of NextGen Protocol Framework (NGPF).
  6. Verify the step summary information and revert to a previous configuration step if needed. Click Finish.

Example:

Assuming we had the following Config Add command:

Config Add Built-In Event obj1 Configuration Add

select="/ixload/repository/test[1]/scenario[1]/

column[1]/element-NetTraffic[1]/traffic "

type="agent-HTTP_Client"

this would return into the obj1 variable the reference of the added HTTP activity element, configured with the cookiejar attribute.
