Causing Testand Step to Skip from CVI

[ofer_o]

Hello:
How can I cause a Testand step to be skipped, using CVI ?
It is prefered that the solution will not use the step name so changing step name will not affect.
I'm using Testand 3.5 & CVI 8.0
Thanks,
Ofer

Hi,

I could use the precondition expression of the step, so that is the condition is met the step will be executed and if its not the step will be skipped.

You could use the RunState.NextStepIndex, by setting this with the value of the step you wish to go to, there are examples of using this on the forum.

Thanks Ray,
Do u have code example at CVI?
Thanks,

There are lots of ways you can do that, but what Ray suggested is probably the best method.

For examples, you can look at your TestStand install directory (ex: C:\Program Files\National Instruments\TestStand 3.5\) in the Examples folder.  A great example to show how to simply modify a TestStand property using the API is called AccessingPropertiesAndVariables (PassingSequenceContextToDll).  You would pass the sequence context to the CVI module and then use the TS_PropertySetValInteger function to set a value in the sequence context.

Hi,

Here's an example (TS2.0.1)

Use in conjuction with the sequence file found in

    TestStand examples\Callbacks\PostStepFailureCallback in FailureHandlerExample.seq.

In the sequence 'SequenceFilePostStepFailure' this function replaces the Step 'Retry Same Step'.

If you changed this step for a CVI Action step with the same preconditions and call retry() it would do the same action as the expression step.

i.e.

   RunState.Caller.RunState.NextStepIndex = RunState.Caller.RunState.StepIndex,
   Parameters.Step.Result.Status = "Failed, Retrying Step..."

Hope this helps
