# This configures the fdb testing system in cmake. Currently this simply means
# that it will get a list of all test files and store this list in a parent scope
# so that we can later verify that all of them were assigned to a test.
#
# - TEST_DIRECTORY The directory where all the tests are
# - ERROR_ON_ADDITIONAL_FILES if this is passed verify_fdb_tests will print
#   an error if there are any .txt files in the test directory that do not
#   correspond to a test or are not ignore by a pattern
# - IGNORE_PATTERNS regular expressions. All files that match any of those
#   experessions don't need to be associated with a test

# This will add a test that can be run by ctest. This macro can be called
# with the following arguments:
#
# - UNIT will run the test as a unit test (it won't bring up a whole simulated system)
# - TEST_NAME followed the name of the test
# - TIMEOUT followed by a timeout - reaching the timeout makes the test fail (default is
#   3600 seconds). The timeout will be reached whenever it ran either too long in simulated
#   time or in real time - whatever is smaller.
# - TEST_FILES followed by typically one test file. The test runner will run
#   all these tests in serialized order and within the same directory. This is
#   useful for restart tests
