It is agonizing to not be able to choose which test to run on the command line when running make test.
The Makefile in ReactiveMP.jl allows for a test_args argument which provides a test files/directories filter to the runtests.jl.
I haven't had time to update the Makefiles of other packages in the ReactiveBayes ecosystem including this one, but this would make life a little bit better for people like me 😀
