Displaying report text based on step result

[rreis]

For reference, I am using TestStand 4.0 and CVI 8.0

I have a CVI numeric limit test step where I would like to print out a report text message only if the step fails.  What I think I need to do is to set Step.Result.ReportText based on the result of the step.  It seems like using a post-expression or a post-action should work, but either I don't know how to use them for this purpose or neither one is capable.    It seems like setting Step.Result.ReportText can only be set from the actual step thats reporting so jumping to another step to perform the action is not an option.  I was also thinking that possibly the SequencFilePostStep engine callback could be overridden but I think that would affect all steps when I just want to affect a few.

Hi,

What about using Engine Callback SequnceFilePostSepFailure ?
It is only called when a Step failed.

That's an option, but it still affects every step that fails which complicates things.

HI,

OK, then i would try the Post Actions in the Step properties.

There you can select for example "On Fail" a sequence call.

See the exsample to attach the report text

Hi,

you could also use the Post-Expressions.

With the following command in the Post-Expressions, you can delete the ReportText when your Step passed.

Step.Result.PassFail==True ? Step.Result.ReportText="" : Step.Result.PassFail

Hi Schnurpsl,

a nice piece of code you figured out  !

It seems that I will use your stuff in future tasks. I 'll give you 5.

Hi,

Just a note, Step.Result.PassFail is only available in the Steps of PassFail step-type. For NumericLimitType, you would have to use something else. You can't use StepResult.Status because this will not have been evaluated when the Post Expression is invoked.

Hi,

yes you´re right. I just thought about the Pass/Fail Test.

But for a NumericLimitTest I´ve got another solution.

In this small sequence I integrated both Tests. To delete the ReportText at the NumericLimitTest, you have to use the Post Actions

Greetings

Sorry, the first Sequence works only with LabView 8.2

This Sequence works without an adapter

Thanks for your help.  I will try the ternary operator method first, it looks like that is a useful statement for the expression fields.
