-"""Base class for host-driven test cases.
-
-This test case is intended to serve as the base class for any host-driven
-test cases. It is similar to the Python unitttest module in that test cases
-inherit from this class and add methods which will be run as tests.
-
-When a HostDrivenTestCase object is instantiated, its purpose is to run only one
-test method in the derived class. The test runner gives it the name of the test
-method the instance will run. The test runner calls SetUp with the device ID
-which the test method will run against. The test runner runs the test method
-itself, collecting the result, and calls TearDown.
-
-Tests can perform arbitrary Python commands and asserts in test methods. Tests
-that run instrumentation tests can make use of the _RunJavaTestFilters helper
-function to trigger Java tests and convert results into a single host-driven
-test result.
