"""Test runner for Mojo application tests.

The file describing the list of tests has to be a valid Python program that sets
a |tests| global variable, containing entries 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)
   #   * "dart".
   "type": "gtest",
   # Optional arguments for the apptest.
   "test-args": ["--an_arg", "another_arg"],
   # Optional arguments for the shell.
   "shell-args": ["--some-flag-for-the-shell", "--another-flag"],
 }

The program may use the |target_os| global that will be any of ['android',
'linux'], indicating the system on which the tests are to be run.
