Better unittest failure output

[Bahman Movaqar via Digitalmars-d-learn]

I am working on a simple project created with DUB[1].
When unit tests the output reads really cryptic to me; for 
example:

     $ dub test
     Generating test runner configuration '__test__library__' for 
'library' (library).
     Target dunit 1.0.11 is up to date. Use --force to rebuild.
     Building d-etudes ~master configuration "__test__library__", 
build type unittest.
     Compiling using dmd...
     Linking...
     Running ./__test__library__
     core.exception.AssertError at source/e002.d(111): unittest

     Error executing command test:

It is almost impossible for me to comprehend anything useful out 
of this, except that, well, the tests have failed :-)

Is there any compiler switch, argument to `assert` or trick to 
make `unittest` output more helpful messages when failing?
