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 Running load tests from Jenkins puts performance in the same gate as the rest of the build. Fail the job on a threshold, not on a chart nobody opens. Keep the CI test small and run the long soak test on a schedule instead. We’ve released a new version of our load testing… Read more »
4 minutes readKey takeaways Lighthouse audits performance, accessibility, SEO and best practices in one run. The score is lab data on a simulated device, so it is a diagnostic rather than reality. Use the individual audits; the composite number moves for reasons that do not matter. If you know nothing about your customers’ experience with your website,… Read more »
2 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 »
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 »
