Exiting an iteration in jmeter if the matching Regular Exp condition is not satisfied

Question

Could you please guide me how to add a condition to exit the current test iteration and proceed with the next set of iteration if the Regular expression value captured in a transaction is 'NotFound'/ ''Null'

Answer 1

1. Add If Controller after the request where you have this Regular Expression Extractor.

2. Use the following expression as Condition (assumes __jexl3() function):

   ${__jexl3("${foo}" == "NotFound",)}
   

3. Add Test Action sampler as a child of the If Controller and set "Action" to Start Next Thread Loop
