 # TODO(hansmuller): The organization of tests in this directory is weird:
 #   * Really, js_unittests tests public stuff, so that should live in public
 #     and be reworked as some sort of apptest.
 #   * Both js_unittests and js_integration_tests should auto-generate their
 #     tests somehow. The .cc files are just test runner stubs, including
 #     explicit lists of .js files.
