Don't inline JMeter Functions or Variables
<https://jmeter.apache.org/usermanual/functions.html> into Groovy
scripts, either use "Parameters" section or go for code-based equivalents.
An one-liner which does the same:
String msg =
org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(org.apache.commons.lang3.RandomUtils.nextInt(500,
1000))
More information:
* The Groovy Templates Cheat Sheet for JMeter
<https://www.blazemeter.com/blog/the-groovy-templates-cheat-sheet-for-jmeter>
* JSR223 Sampler Documentation
<https://jmeter.apache.org/usermanual/component_reference.html#JSR223_Sampler>,
pay special attention to the chapter:
/When using this feature, ensure your script code does not use
JMeter variables or JMeter function calls directly in script code as
caching would only cache first replacement. Instead use script
parameters./

hi
I think I am probably overlooking something simple here and would
appreciate any help...
- Using Jmeter 5.4
- Script should:
> pick a random number between two given numbers (lower and higher
limit)
> Use this random number to produce a random string
The script is placed in a JSR223 sampler:
//Set a random nummber between 500-1000 for message length
MESSAGE_LENGTH = ${__Random(500,1000)}
log.info("################## MESSAGE_LENGTH : " + MESSAGE_LENGTH)
//Generate a random string which uses the message length from above
String msg =
${__RandomString('MESSAGE_LENGTH',abcdefghijklmnopqrstuvwxyz)}
log.info("################## myLength : " + msg)
I get the following output in the logs:
