'''Runs an app through Quantify and verifies that Quantify was able to
successfully instrument and run it. The original purpose was to allow people
to run Quantify in a consistent manner without having to worry about broken
PATHs, corrupt instrumentation, or other per-machine flakiness that Quantify is
sometimes subject to. Unlike purify_test, the output from quantify_test is
a binary file, which is much more useful in manual analysis. As such, this
tool is not particularly interesting for automated analysis yet.
