-Classes in this file define additional actions that need to be taken to run a
-test under some kind of runtime error detection tool.
-
-The interface is intended to be used as follows.
-
-1. For tests that simply run a native process (i.e. no activity is spawned):
-
-Call tool.CopyFiles(device).
-Prepend test command line with tool.GetTestWrapper().
-
-2. For tests that spawn an activity:
-
-Call tool.CopyFiles(device).
-Call tool.SetupEnvironment().
-Run the test as usual.
-Call tool.CleanUpEnvironment().
