1) tests should run as part of running tests, not as part of the build
2) the build should be silent. this step prints a bunch of "running tests" lines

[Sami, 2016/10/11 00:14:03]

Sorry about that; Fix here: https://codereview.chromium.org/2411563002/

As far as I can tell GN doesn't seem to have built-in support for non-C++ tests
so I'll just make this a manual test for now and see about updating the bot to
run this explicitly.
