Jmeter has been used to stress test our application. It supports HTTP, HTTPS, and POSTs, as well as GETs and other requests. Using Jmeter's CSV capability, we can test a single API with several calls. I utilize this tool because all requests, CSV, and API bodies are easily customized. The results are recorded in the format that we desire. Graphs, tables, and other report generating settings are provided. Even failing APIs can be segregated and displayed in RED, which is really useful. It provides a scripting language via the JMeter GUI that allows us to do a variety of operations without programming.
