# For an executable target already defined, CMake tests are added with the
# following syntax:
#
# add_test(NAME <name> [CONFIGURATIONS [Debug|Release|...]]
#            [WORKING_DIRECTORY dir]
#            COMMAND <command> [arg1 [arg2 ...]])
#
# The GROMACS convention to get the appropriate compilation environment for
# unit tests is the gmx_add_unit_test macro, defined in
# src/testutils/TestMacros.cmake, which does not allow arbitrary argument
# passing to add_test. Instead, use set_tests_properties().

#
# Test public interface.
