In JMeter, Compare Assertion is used for comparing the given text or regular expression string with the response content. I tried to find out the practical use of compare assertion but did not get any useful purpose of this assertion element. I just got to know that compare assertion consumes a high percentage of CPU and memory space and it is not recommended to use it during the load test.
The compare assertion is basically used for either functional testing or debugging purpose. But still, I do not understand the exact use of compare assertion.
If you know any additional details about Compare Assertion or how it can be used practically then provide the information in the comment box.
