The reporter doesn't do a very good job of showing when a test has failed. This screenshot is of a test that timed out, but the experience isn't much better when the test throws. All I see is:

[13:13:22] Starting '!test.unit.js/karma-run'...
Chrome 46.0.2490 (Mac OS X 10.10.5) integration tests react to record changes should consume text node changes FAILED

LGTM with local fixes to color reporter and indentation.
