# There are three kinds of test we support (the KIND parameter):
#
# - SEASTAR: Unit tests which use macros like `SEASTAR_TEST_CASE`
# - BOOST: Unit tests which use macros like `BOOST_AUTO_TEST_CASE`
# - CUSTOM: Custom tests which need to be specified
#
# SEASTAR and BOOST tests will have their output saved for interpretation by the Jenkins continuous integration service
# if this is configured for the build.
#
# KIND can be omitted, in which case it is assumed to be SEASTAR.
#
# If SOURCES is provided, then the test files are first compiled into an executable which has the same name as the test
# but with a suffix ("_test").
#
# WORKING_DIRECTORY can be optionally provided to choose where the test is executed.
#
# If LIBRARIES is provided along with SOURCES, then the executable is additionally linked with these libraries.
#
# RUN_ARGS are optional additional arguments to pass to the executable. For SEASTAR tests, these come after `--`. For
# CUSTOM tests with no SOURCES, this parameter can be used to specify the executable name as well as its arguments since
# no executable is compiled.
