+# is expected the lower-cased test name plus the .cpp extension.
+# The test case is automatically linked against Qt5::Test, GMock, Quassel::Common and
+# Quassel::Test::Main, which contains the main function. This main function also instantiates a
+# QCoreApplication, so the event loop can be used in test cases.
+#
+# Additional libraries can be given using the LIBRARIES argument.
+#
+# Test cases should include testglobal.h, which transitively includes the GTest/GMock headers and
+# exports the main function.
