Variables, may they be constant or dynamic, are an essential part of load testing. We already learned how to manipulate these values by extracting and re-injecting them inside one Virtual User. But what if we need to share these values between several Virtual Users ? In this blog post, I will show you just how to do that, using the MQ technology.

This blog post is a guide to help you write Gatling scripts in order to load test web applications efficiently. It follows our second Gatling Simulation scripts parameterization article. We will continue to load test a fake e-commerce, and so we are going to improve our Virtual User to make it browse the store in a more humanly way. We start where the previous blog post ended, with a simulation script that uses a CSV feeder and a Regular Expression extractor to visit dynamic pages of the pet store.
