# This script manages the addition of tests.
# The tests are orchestrated by a shell script,
# configured using opm_set_test_driver()
# and then the appropriate helper macro is called to
# register the ctest entry through the opm_add_test macro.
# Information such as the binary to call and test tolerances
# are passed from the build system to the driver script through
# command line parameters. See the opm_add_test() documentation for
# details on the parameters passed to the macro.
