-// This class sets up the environment for running the native tests inside an
-// android application. It outputs (to a fifo) markers identifying the
-// START/PASSED/CRASH of the test suite, FAILURE/SUCCESS of individual tests,
-// etc.
-// These markers are read by the test runner script to generate test results.
-// It installs signal handlers to detect crashes.
