# Defines a Dart test suite that requires connecting to a remote target.
#
# Parameters
#
#   sources (required)
#     The list of test files, which must be within source_dir.
#
#   source_dir (optional)
#     Directory containing the test sources. Defaults to "test".
#
#   deps (optional)
#     List of labels for Dart libraries this suite depends on.
#
#   disable_analysis (optional)
#     Prevents analysis from being run on this target.
#
# Example of usage:
#
#   dart_host_to_target_test("baz_test") {
#     source_dir = "."
#     sources = [ "foo_bar_baz_test.dart" ]
#     deps = [
#       "//foo/baz",
#       "//third_party/dart-pkg/pub/test",
#     ]
#   }
