# Defines a host-side test for a triage configuration
#
# Packages a set of triage configuration files into a single test which
# runs all of the tests in the `test` section of the configuration file.
# This test will pass if all of the tests pass and fail if any of them fail.
#
# Parameters
#
#   sources (required)
#     The list of configuration files. These sources must be within source_dir.
#
#   source_dir (optional)
#     Directory containing the test sources.
#     Defaults to "config".
#
# Example of usage:
#
# triage_config_test("some_test") {
#   sources = [
#     "bar.triage",
#     "foo.triage",
#   ]
# }
#
# Example of running:
#
#   fx test some_test
#
