Correlation in JMeter

Question

If we have dynamic values in JMeter, in Response Body, Response Headers, and Request Headers, then we can correlate using Post Processors. But If we have dynamic values in the Request Body, then how can we correlate.

Could anybody please help me.

Answer 1

Where do these "dynamic values" come from?

• If you need to populate them with the data from the response - correlation approach applies
• If you need to populate them from external sources - it's called parameterization, the most commonly used approach is CSV Data Set Config
• If you need to provide random/unique values - look at JMeter Functions
