Currently micromixin-testing-suite-neo is a skeleton of what it could be, though I am fairly certain that it will grow over time.
This is also the first full-scale JPMS of SLL. Launcher-micromixin felt easier on the bones, but that might be caused by launcher-sponge having done all the hard work already. Regardless, launcher-micromixin did show that there was a serious flaw with how micromixin-runtime was handled, so we have decided to deprecate the package. It will be removed shortly (within the 0.8.0 cycle), meaning that newer artifacts will not be published.
Also unlike the old testing suite (which will be kept in this repository for a while at least), the output of the testing suite can be viewed in the jenkins log. Well at least hopefully - it's a bit more difficult to test your jenkins config locally so we'll have to hope that I got it right on the first try. (commit: 6ddad3a)
