@rbuckton this was working in the commit before #23893 (c437404)

gulp no longer works at all, but jake runtests-browser now fails immediately with no message:

> jake runtests-browser
jake aborted.

@andy-ms You might want to use to debug in the mean time

node --inspect-brk node_modules\mocha\bin\_mocha -R mocha-fivemat-progress-reporter -g "sometest" --colors -t 40000 built\local\run.js

@andy-ms @rbuckton has been working on a patched gulp-typescript that works with project references; hopefully it'll be good to use soon.

@sheetalkamat Thanks, but I've noticed a lot of segfaults / illegal instruction errors when running that -- running through a browser seems to be a lot more reliable. Hopefully we get gulp runtests-browser working again soon (looks like that task was deleted from the jakefile).

runtests-browser was not carried forward to gulp
