| 5 """Base class for host-driven test cases. | |
| 6 | |
| 7 This test case is intended to serve as the base class for any host-driven | |
| 8 test cases. It is similar to the Python unitttest module in that test cases | |
| 9 inherit from this class and add methods which will be run as tests. | |
| 10 | |
| 11 When a HostDrivenTestCase object is instantiated, its purpose is to run only one | |
| 12 test method in the derived class. The test runner gives it the name of the test | |
| 13 method the instance will run. The test runner calls SetUp with the device ID | |
| 14 which the test method will run against. The test runner runs the test method | |
| 15 itself, collecting the result, and calls TearDown. | |
| 16 | |
| 17 Tests can perform arbitrary Python commands and asserts in test methods. Tests | |
| 18 that run instrumentation tests can make use of the _RunJavaTestFilters helper | |
| 19 function to trigger Java tests and convert results into a single host-driven | |
| 20 test result. | |
