JMeter If Controller

Question

not too sure if this is a user error but I can't seem to get this working. I have a test that returns 200 and this always hits the If controller, but the following fails.

I get a productID, if this is nested then i get the first one.
Regex is prodID "ProductId":(.*?), $1$ 0

Then as I want to use this in another thread group I cjhange to a property: ${__setProperty(prodID-${__threadNum},${prodID},)}

Then i use If Controller as ${__P(prodID-${__threadNum})} == "18"

Then it runs the same regex, but this time with $2$

Problem is that the If Controller isn't getting run on any, is there a way I can see this, or even is the above correct?

Thanks

Answer 1

The If Controller run its children if the expression evaluates to true

You're giving 18 == "18", it is not equal to true therefore the children are not getting executed.

I would suggest using __groovy() function instead like:

${__groovy(props.get('prodID-' + ctx.getThreadNum()).equals('18'),)}

where

• props is a shorthand for Properties class instance holding JMeter Properties
• ctx is a shorthand for JMeterContext class instance
