JMeter If Controller, "Not" operator

[Tong Sun <su...@gmail.com>]

Hi,

Does the JMeter If Controller has a "Not" operator?

https://jmeter.apache.org/usermanual/component_reference.html#If_Controller

I.e. can I use

!${JMeterThread.last_sample_ok}

?

If Controller will execute its children if the function (or variable) 
you place in the condition field returns *true*

If you want to execute something conditionally if the previous sampler 
is not successful you can use i.e. __groovy() function 
<https://jmeter.apache.org/usermanual/functions.html#__groovy> like:

${__groovy(vars.get('JMeterThread.last_sample_ok') == 'false',)}

Where *vars* stands for JMeterVariables 
<https://jmeter.apache.org/api/org/apache/jmeter/threads/JMeterVariables.html>class 
instance, see Top 8 JMeter Java Classes You Should Be Using with Groovy 
<https://www.blazemeter.com/blog/jmeter-java-classes> article for more 
information on this and other JMeter API shorthands available for the
