BeanShell Assertion is a scripting-based Assertion element of JMeter. It means that you need to implement the assertion logic by yourself using one of the supported scripting languages. Usually, it is helpful when you need to define assertion or validation logic based on your requirement and want to write some unique algorithm which is not currently provided by JMeter. You can create your own implementation of the algorithm using BeanShell Assertion.
