6 Classes in this file define additional actions that need to be taken to run a
7 test under some kind of runtime error detection tool.

9 The interface is intended to be used as follows.
10
11 1. For tests that simply run a native process (i.e. no activity is spawned):
12
13 Call tool.CopyFiles(device).
14 Prepend test command line with tool.GetTestWrapper().
15
16 2. For tests that spawn an activity:
17
18 Call tool.CopyFiles(device).
19 Call tool.SetupEnvironment().
20 Run the test as usual.
21 Call tool.CleanUpEnvironment().
