Using Groovy in JMeter: Demos, Context Access, and Throughput Insights

Initially unfamiliar with JMeter, the author discovered that JMeter has long supported Groovy, which sparked the creation of a demo and an article; since then, multiple demos beyond the basic ctx and script file usage have been completed.

The ctx object enables access to higher‑level information such as SampleResult or prev. Although official documentation mentions thread scheduling features for interrupting threads or loops, the author finds the built‑in JMeter thread management more practical, so the Groovy experiments in JMeter conclude here.

An accidental observation of a theoretical throughput discrepancy in JMeter leads the author to offer two recommendations: consult official or community documentation frequently, and engage in discussions with peers to explore solutions.

The page then lists the complete set of JMeter‑focused articles, covering topics such as handling assertions and logs with Groovy, manipulating variables, executing command lines, processing request parameters, using regex extraction, managing cookies and headers, and analyzing throughput errors.

A disclaimer notes that the original article was first published on the "FunTester" public account and that redistribution (except by Tencent Cloud) is prohibited.

Additional curated technical articles are presented, including resources on Linux performance monitoring (netdata), performance‑testing frameworks, command‑line performance testing, HTTP mind maps, visualizing test data, measuring asynchronous API latency, and multi‑login performance strategies, as well as non‑code pieces on programming mindset, JSON basics, tester self‑improvement, automation pitfalls, full‑stack automation engineering, and the debate between manual and automated testing.
