 # This file contains a list of Mojo gtest unit tests.
 #
 # This must be valid Python. It may use the |config| global that will be a
 # mopy.config.Config object, and must set a |tests| global that will contain the
 # list of tests to run.
 #
 # The entries in |tests| are dictionaries of the following form:
 #   {
 #     # Required URL for apptest.
 #     'test': 'mojo:test_app_url',
 #     # Optional display name (otherwise the entry for 'test' above is used).
 #     'name': 'mojo:test_app_url (more details)',
 #     # Optional test type. Valid values:
 #     #   * 'gtest': (default)
 #     #   * 'gtest_isolated': like 'gtest', but run with fixture isolation.
 #     #                       i.e., each test in a fresh mojo_shell
 #     'type': 'gtest',
 #     # Optional arguments for the shell or test.
 #     'args': ['--some-flag-for-the-shell', '--some-flag-for-the-test'],
 #   }
