the expression Field for a step does not allow use of If else statements
should I take it as "limited" feature of teststand & use the Statement-step or am I misled!
What exactly are you trying to do? If you are trying to set a value, then it can be done.
locals.num = locals.bool? TrueValue:FalseValue
It's true that expression allow only "a boolean select".
What is the use case for more complicated selections with more than two options?
Why is it beneficial to implement this as a step component (that means: obfuscating options) instead of displaying the selection in an obvious, readable way as multiple steps?
