Normally any information that would be useful to easily detect
the reason of failure. A good test explains why it failed, the best test
submits a bug report and provides a patch, the worst test
just complains that it failed.

I would not wish to debug just to figure out that the reason of failures is
that I've forgot to include something to classpath or there is another
config problem

fail() is not always convinient, for example, how would you print
stack trace to fail()? Meanwhile stacktrace is most often enough
to find what the problems are and sort them out.
