3 minutes readKey takeaways Load test the endpoints your clients actually call, weighted the way they call them. Send realistic payloads and headers, since size and content change server behaviour. Assert on the response body as well as the status code. In order to learn how to test your APIs, especially how to load test your APIs,… Read more »
2 minutes readKey takeaways A high standard deviation means inconsistent response times, which users notice more than a slow average. Two runs with the same mean can behave completely differently, and this is how you tell. Pair it with percentiles rather than reporting either alone. Standard Deviation is an important metric in performance testing analysis and informs… Read more »
3 minutes readKey takeaways JMeter executes by element type, not by the order you see in the tree. Config elements and pre-processors run before samplers regardless of position. Knowing the order explains most surprising variable and timer behaviour. The execution order of the elements in an Apache JMeter performance test plan is very important, it helps understand… Read more »
6 minutes readKey takeaways Recording in the browser captures the real request sequence including headers you would otherwise miss. Strip analytics and third-party calls from the recording before running it. Parameterise the captured values; a replay of one session is not a load test. Performance testing is more critical than ever. Whether you’re dealing with complex microservices… Read more »
< 1 minute readKey takeaways Homebrew installs JMeter under its own prefix, so the config is not where the docs say. Use brew –prefix to locate the install rather than guessing the path. Edit the properties file there, and remember an upgrade can replace it. When you choose to install JMeter using Homebrew you may find yourself a… Read more »
2 minutes readKey takeaways JMeter defaults to a small heap, which causes out-of-memory failures on large tests. Raise the heap in the startup script, and run non-GUI with listeners disabled. If you still run out, the answer is distributed load rather than a bigger heap. Why is Apache JMeter very slow when creating and running load tests?… Read more »
6 minutes readKey takeaways The Plugins Manager handles dependencies, which manual jar copying does not. Install it once, then add and update plugins from inside JMeter. Restart after installing or the new elements will not appear. Introduction Hey there! If you’re here, you’re probably looking to supercharge your JMeter experience by installing the JMeter Plugin Manager. Whether… Read more »
