Here is a screenshot of Krakens debug editor for the ViewCategory server response body: The product ID is present in the tag, between the string productId= and ". But we are not going to copy/paste GET requests for every Category/Product/Item of the PetStore. Lets copy the HTML body in an online regexp testing tool to try it out: As you can see all the product IDs are found. What's New in 3.5 See full Release Note on GitHub. Please remember to make a Cassandra database backup before upgrading. In Gatling scripts, specific Feeders are dedicated to each use case: You can even use a custom separator with the syntax val feeder = separatedValues("categories.txt", '/'). Lets create a simpler CSV file named categories.csv that contains only on pet shop categories: In Gatling, copy thisfile in the /user-files/resources/two/ folder. Gatling Enterprise 1.16.0 is compatible with Gatling 3.3, 3.4, 3.5, 3.6 and 3.7. A few thing to remember for this tutorial: Finally, its often quicker to copy/paste the server response in an online Regex tester to check that it works fine instead of running a load tests.

Gatling is a load testing tool that comes with excellent support of the HTTP protocol - which makes it a really good choice for load testing any HTTP server.. Left like that it would be problematic for many web applications such as our sample e-commerce. In a Gatling .scala Simulation script, you set the query parameters either by appending then manually at the end of the request path: Or a better solution is to use the queryParam operator: The viewCategory parameter has no value, but you still need to pass an empty string "". The regular expression in this case is productId=(.*)". Please upgrade ASAP if youre using binary repositories, see DEV-543, If you plan on deploying maven projects as fatjars in a maven repository, please upgrade. Learn about upcoming Gatling events! So you can inject a random category with the ${categoryId} string: The complete simulation script is downloadable here: In Kraken, you can debug your Gatling simulation to check which requests are sent: Here we can see two requests (I deactivated resources inferring for this debug run to display only the requests to the HTML pages): The request URL is visible at the upper left corner of the Debug editor. 4. A single cookie will be used in your browser to remember your preference not to be tracked. I've seen that Gatling uses LogBack as logging system, and in this blog post on LogBack news they are talking about it: http://logback.qos.ch/news.html In Kraken, environment variables are set when executing the simulation: Here, the env variable CATEGORIES_SET_ID will have the value categories1 on the kraken-1 host and categories2 on the kraken-2. If you have more that two hosts you could easily add a row to define the Categories Set ID for it. OctoPerf 2014 - 2023. Debugging this script in Kraken shows us that three requests are executed (as long as the resources inferring is commented out of course): Want to go further? Where Gatling users ask questions, help each other and share experience. What about creating a feeder based on the output of a check(regexp())?

Many values extractors are available in Gatling, they take the place of the regex keyword in the simulation script. I think that every load tester (and more generally every developer) should have at least a basic knowledge of Regexps and be able to write even simple patterns. The idea here is to inject an identifier of the categories when running the load test, lets say CATEGORIES_SET_ID. Instead, please check the samples on GitHub. Still, youre recommended to upgrade to 3.9.0, older versions are no longer maintained. FrontLine has been renamed to Gatling Enterprise. If you have any feedback, just mention me in the comments below. Its time to run our simulation script with 100 concurrent users and see how it goes (The complete script is downloadable here or directly available in Kraken com.octoperf.tutorials.two.PetStoreSimulation4.scala): Opening the Grafana report in Kraken shows us how many request are sent for each page: First of all, thats a lot of requests (more than 150K all pages combined) for only a few concurrent users. Gatling being written in Scala, it uses the Java patterns format. Its easier to maintain a dynamic load testing script when the tested application is updated (for example with new products in the case on an e-commerce). Updates io.gatling.highcharts:gatling-charts-highcharts from 3.8.0 to 3.8.1. Apache JMeter and What about Gatling?
