About Variables and the Operator Information Process
By adding an Operator Information process to a test procedure, you can change
selected variable values while the test is running.
When the test procedure is running and the Operator Information process is
triggered, it displays a run-time window. This window may require the operator
to verify or change the information specified by the test designer and click OK to
continue the test. All variable values are written to the test procedure data file.
As the test designer, you can choose the type of information displayed in the run-
time window, including predefined variables. You can choose which variables the
operator can change in the window.
You can control when the operator has the ability to change variables by
strategically placing Operator Information processes in the test procedure, or by
nesting them in a repeating Group process.
An example using the
Operator Information
process with Variables
For example, suppose you create a test procedure that includes the following:
• A Group process that runs three times
• Within the Group process, a Cyclic Command process that starts when the
Group process starts, and an Operator Information process that starts when
the Command process is done.
• Within the Cyclic Command process, you select frequency as a variable.
• Within the Operator Information process, you select frequency as a variable
to be displayed on the execution window, and you select frequency to be
editable.
