We are going to discuss JMeter Assertions in this post. There is already a fantastic Ultimate Guide post about how to use JMeter Assertions in the JMeter section of the OctoPerf Blog and this can be found here. Before starting on this post, it would be advisable to read the post on JMeter Assertions that already exists and linked above to get a firm understanding of how they work and the various types that exist.
This blog post is going to use the information in this post and consider how assertions can be used to help your performance testing especially when building complex tests and using them to make decisions as your tests run.
The aim of this post is not to reiterate the contents of the Ultimate Guide blog post but to take an example of one or two of the regular expressions and discuss how they can be used in the wider context of performance testing scenarios.
The reality is that any of the assertions can be used to manage your performance testing and it depends on the technology you are testing and therefore the assertions best suited to this.
