Trace Command Step in Step Configuration Wizard
A Trace step logs an argument string to the application logs.
To add a Trace command step using the GUI scripting support:
While in the Script Steps pane, add a step by choosing the Actions > Add step... command. Select a Trace command, click thebutton to validate the selection, and specify the following parameters:
- Run Type: A Trace step can only be executed sequentially (Sequential).
- 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 Script Steps table and choosing the Exclude command from the context menu that appears.
- Description: An optional step description can be associated with a step.

Define the Conditional Execution settings as explained below.Conditional Execution settings enable you to define the system conditions a script 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 script.
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 script execution continues.
- Exit Test: After performing the specified procedure, the script 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.
In the Expression Builder GUI, define a message and optionally a logging format specifier, such as for example %s for string formatting or %d for decimal formatting.The message, a valid Tcl expression or a Tcl code fragment, is defined by double-clicking in turn the desired Tcl commands and operators, and TestComposer variables. For detailed information on using the Expression Builder and creating Tcl expressions refer to Using the Composer Expression Builder.
Click Next.
Verify the step summary information and revert to a previous configuration step if needed. Click Finish.Examples:
Assign x 13
Trace "Numeric %d" $x // returns `Numeric 13'
Trace "%d" $x // returns 13
Trace $x // returns 13
Assign y "some text"
Trace "String %s" $y // returns `some text' string
Assign z 12.34
Trace "Float %f" $z // returns `Float 12.34'
Trace "Text without variables" // returns `Text without
//variables' string
