 """A framework to run PyAuto HTML media tests.
 
 This PyAuto powered script plays media (video or audio) files (using the HTML5
 tag embedded in an HTML file). The parameters needed to run this test are
 passed in the form of environment variables (such as the number of runs).
 media_test_runner.py is used for generating these variables
 (PyAuto does not support direct parameters).
