if then else

[Clint Eastwood]

Is there an equivalent to IF-THEN-ELSE in Teststand? I'm checking a step to see IF its between a ceratin value. If so, THEN execute that step, ELSE excute a different step. I tried the PRECONDITIONS tab in TS but how do I avoid executing the ELSE part of the step ?

Clint,
You could use the Preconditions of the ELSE step so that it will only run IF the first step did not. So if the first IF is FALSE then that step is skipped and THEN the second step runs. Alternatively you could use the flow control step type here:-

Clint,

If you want to jump over the "else" step when the "if" condition is true, use a post action in the "if" step to skip over the "else" step. You can just set the custom condition expresion to TRUE then in the On Condition True, jump to the step after the else.

For the simple if-then-else structure, I prefer to set the precondition of the "else" step to RunState.PreviousStep.Result.Status=="Skipped". This enables the two steps to be easily cut and pasted as no step names that may have to be changed are involved.
