+# Convenience environment for running individual tests from the
+# battery of templated source tests.
+#
+# You should pass this the part of a test node's id after "::". For
+# example, to run the test
+# buildstream/plugintestutils/_sourcetests/fetch.py::test_fetch_cross_junction[git-inline]
+# you would do tox -e sourcetests -- test_fetch_cross_junction[git-inline]
+#
+# This does rely on the fact that none of the tests in
+# buildstream.plugintestutils have the same name.
