 """Base class for Android Python-driven tests.
 
 This test case is intended to serve as the base class for any Python-driven
 tests. It is similar to the Python unitttest module in that the user's tests
 inherit from this case and add their tests in that case.
 
 When a PythonTestBase object is instantiated, its purpose is to run only one of
 its tests. The test runner gives it the name of the test the instance will
 run. The test runner calls SetUp with the Android device ID which the test will
 run against. The runner runs the test method itself, collecting the result,
 and calls TearDown.
 
 Tests can basically do whatever they want in the test methods, such as call
 Java tests using _RunJavaTests. Those methods have the advantage of massaging
 the Java test results into Python test results.
