jake runtests-browser t=yourTestName has got broken and the Run Tests button just shows passes: 0 failures: 0 duration: 0s.

I'm testing on Windows 10 build 10240 and io.js v2.3.1. It had worked a week ago and got broken when I received the latest TypeScript bits. Updating io.js to version 3.0.0 doesn't fix this problem.

jake runtests t=yourTestName still works as expected.
