cant run unittests

[dom via Digitalmars-d-learn]

how can i run my unittests for a dynamic library? some weird 
conflict is reported between main functions, my project doesnt 
contain any main function.

i really love D, but problems like this make me wanna switch :/

using:
dub test --arch=x86

lucy ~master: building configuration "__test__library__"...
../../tmp/dub_test_root-0ce1acbf-ecb9-4abf-8199-e7a23bd783dc.d(21,12): Error: function D main conflicts with static import dub_test_root.main at ../../tmp/dub_test_root-0ce1acbf-ecb9-4abf-8199-e7a23bd783dc.d(11,15)
