Currently, the most popular approach for API testing is to send a JSON payload file instead of using data with parameters. This post will show how to do JMeter Load Testing with a JSON payload. To perform sending the JSON payload we need a different configuration. First, we need to add HTTP Header Manager into our HTTP Request in order to set Content-Type as application/json. We then put the JSON payload into the Body Data sectionRead More →

Disclaimer: This post is for those still using Beanshell. However, you should know that the Philippe Mouawad, JMeter contributor, has asked us to pass on that everyone should “avoid Beanshell in favor of JSR223 + Groovy because Beanshell is old, slow and does not support Java 5 and upper syntax.” If you still will be using Beanshell for whatever reason, here are Beanshell for JMeter Best Practices. JMeter has powerful abilities to perform general tasks outRead More →

Many secure web applications use cookie data for their session management. On the other hand, there are still a considerable number of web applications that use a URL rewriting technique for the management of their session information. Although it has some potential security risks, there are several advantages to using this technique. For an example, even if a client browser’s cookie is disabled, it still works. The other advantage is thanks to URL Rewriting, users seeRead More →

Alexander Podelko, who talks and writes about performance-related topics, recently wrote in his latest load testing report that “It appears that Apache JMeter became the most popular load testing tool.” In this report he looked at the state of the load testing space since his previous report five years earlier. And he found that load testers use JMeter the most. Alexander continued: “Another interesting trend is that JMeter scripts become a de facto standard.” So weRead More →

HTTP Cookie Manager

This is one of our most popular blog posts. We’ve added new information on the property save.cookies at the bottom of the post. This post answers a common JMeter question: I would like to understand and see an example to use HTTP Cookie Manager and explain the different reasons I might use it. Cookie Characteristics In a stateless internet, many sites and applications use cookies to retain a handle between sessions or to keep some stateRead More →

Advanced Load Testing - Granularity

JMeter Reports default to a granularity of one minute. That granularity could be a problem. This post will talk about Advanced Load Testing – Granularity in your JMeter Reports. Did you know JMeter Reporting Dashboard allows you to control your granularity? See the Apache JMeter docs for all of the details. There are lots of adjustable settings, so why is granularity so important. Example: Advanced Load Testing – Granularity One of our RedLine13 customers shared aRead More →

This is one of our most popular blog posts – File Uploads. Check out a new section #3: Adding Parameters to your HTTP Request. Read below for lots of great information. There are many cases of testing performance of API Endpoints for file uploads. We chose to demonstrate scaling out such a test building our load test plan in JMeter. JMeter supports file uploads natively within the HTTP Request, and Redline13 supports attaching files to your test plan.Read More →

This is one of our most popular posts – JMeter Capturing Full Output. We’ve updated the post with new and updated content with the help of contributor Mustafa Mahir Kaplancı. See the updates at the end of the post. While running a distributed Apache JMeter test how can you capture the full output instead of just performance results? The following steps will show how to do what we call JMeter Capturing Full Output.. One is because ofRead More →

Three new ways that life can be a little easier for JMeter Load Testers. We’ll start with the JMeter Dashboard Report. JMeter Dashboard Report You’ve been able to generate the Apache JMeter Dashboard report for a long time yourself or with RedLine13. But you had to download it, then expand, then view.  Now you can View it inline! So you get the RedLine13 generated reports and you also get access to the full JMeter report as well.Read More →
