Random String Generator for REST Request

Hi All,   I was wondering if anyone could help with being able to create random data for a POST request that contains about 1000 lines of json.  So it would just REPLACE "string" any time it is men...

Ah... I think I may have confused you with example... I didn't want to do it through the Properties step as that would just be creating replacements for a specific field then referencing them in the Json Payload. eg:

def firstName= generator( (('A'..'Z')+('a'..'z')).join(), 7 )
def lastName= generator( (('A'..'Z')+('a'..'z')).join(), 9)
def addressLine = generator( (('A'..'Z')+('a'..'z')+('0'..'9')).join(), 20)

 

If I have a 500 fields with "string" I don't want to have to define them all in a Groovy step!  

 

I was looking for an easy way to basically do a REPLACE ALL "string" with random data in the JSON payload

Oh...so literally the fields have "string" in them and you want to replace them all?

You've already identified the groovy method to do this....replaceall() why dont you just use that and drop the random requirement....adding random values arent really gonna add all that much to the level of rigour in your tests anyway...

    Hello User999 

     

    Here is an attempt at your solution.  Drop this into a groovy test step to exercise it and add a "Properties" test step to catch the resultant new json. Hack it up as desired.  There might be portions that are helpful to your final resolution...

     

    import groovy.json.JsonSlurper;
import groovy.json.JsonOutput;

log.info 'Test Step "' + testRunner.runContext.currentStep.name + '" start...';
log.info "";

// embellished some sample json I had laying around...
def String jsonStr = """

      log.info "   elementAfter=${element.value}";
