3 minutes readKey takeaways Recording in the browser captures the real request sequence, including headers you would forget. Review the recording before running it: analytics and third-party calls get captured too. Parameterise the recorded values, since a replay of one session is not a load test. This article explains how to quickly record and run load tests… 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 »
2 minutes readKey takeaways JMeter is written in Java, which is why it needs a JRE and behaves like a Java application. Scripting inside tests is usually Groovy through JSR223, which performs best. You can build most test plans without writing code at all. Apache JMeter is a Java open source tool. If you want to run… Read more »
2 minutes readKey takeaways JMeter builds a test plan of thread groups and samplers, then runs it as concurrent Java threads. Each thread is a simulated user, so machine resources cap how many you can generate. Listeners are for debugging. Leaving them on during a real run distorts the result. JMeter offers the ability to simulate a… 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 No. The GUI is for building and debugging plans, not for generating load. The GUI consumes the memory and CPU you wanted for virtual users. Run non-GUI with results written to file, then open the file to analyse. Often software developers get to ask themselves the question: Should I just run the tests… 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 »
