 // This class sets up the environment for running the native tests inside an
 // android application. It outputs (to logcat) markers identifying the
 // START/END/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 injects an event listener in gtest to detect various test stages and
 // installs signal handlers to detect crashes.
