Data Source Edit Tab
Use the Data Source edit tab of the Pass/Fail Test step in the TestStand Sequence Editor to specify the data source for the Boolean value the Pass/Fail Test step uses to determine whether the step passes.
The Data Source edit tab contains the following option:
- Data Source Expression —A Boolean expression the step uses to determine whether the step passes or fails. By default the step specifies the Step.Result.PassFail property. You can customize this expression when you do not want to set the value of Step.Result.PassFail in the code module . For example, you can set the data source expression to refer to multiple variables and properties such as: RunState.PreviousStep.Result.Numeric * Locals.Attenuation > 12 .
