I think there’s one question you should answer in order to fully describe your “testing framework”: is it being used for “end to end tests” or “integration tests” or “unit tests”? https://k-hartanto.medium.com/testing-pyramid-and-testing-ice-cream-cone-what-is-the-difference-6ddde3876c20
For unit tests, something like https://en.wikipedia.org/wiki/JUnit is useful. For testing a program after it’s deployed, something like https://jbehave.org/reference/stable/story-syntax.html is useful. You get different information about your program from each type of testing, and one type can detect issues even if the other didn’t, so doing both is useful.
Initially, when I navigated to https://ibis.wiki/ I saw “502 bad gateway”. That is not a good first impression…
Reloading the page let me see more useful things though.
