Experimenting with GC-less (heap-less) Java
I haven't had chance to use it properly yet, but I think JfrUnit[0][1] is a good option here to test non-functional behaviour like memory usage and garbage collection.

Inducing sustained GC
I do not know of any library that would particularly help here, except maybe this thingie might help with writing tests to assert your expected behaviour holds: https://github.com/gunnarmorling/jfrunit (A potentially relevant example here: https://twitter.com/gunnarmorling/status/1335326054496555008). However, there's no public release as of yet.
