Windows development issues

[alisd23]

Having issues developing on windows (7) on a fresh install (master).

Running npm test causes all 118 test suites to fail with the error:

Changing testRegex in the package.json from/tests/to justtests` seems to fix those issues, because the last character is an escape character, it's invalid regex.

There is another regex error though:

Not sure where that regex comes from though...

There is also a 3rd error

which just looks like a unix -> git bash crossover issue. Possibly another escape character issue.

Does anyone run on windows and had similar issues?

We're tracking Windows fixes for the build system in #9540, let's just make sure we fix tests there too.
