Native TS support would be nice to have

I haven't dug yet, but I think we could integrate https://github.com/TypeStrong/ts-node/ and load it on demand if needed.

+1, as ospec **/tests/**/*.js --preload ts-node/register doesn't seem to work, it looks for a relative filepath instead of a module.

As a workaround in the mean time, you can load ts-node/register from a local file.
