I'm not sure how exactly it could be implemented, but at present I don't think Umbrello has any unit testing framework that is invoked on the standard GCS make check target.
Git commit f3e4b43cda2284730a5ed0334554c80b545a2dc5 by Ralf Habacker. Committed on 03/03/2017 at 10:21. Pushed by habacker into branch 'master'. Add 'check' target as an alias for 'test' to build system. CMake build system by default adds a 'test' target for running tests.
