Error running tests

[elsehow]

After successfully running grunt compile / grunt build, I try to run the tests with grunt test, but see the following

Running "jshint:files" (jshint) task
>> 15 files lint free.

Running "jscs:all" (jscs) task
>> 15 files without code style errors.

Running "connect:server" (connect) task
Started connect web server on http://0.0.0.0:9998

Running "saucelabs-mocha:all" (saucelabs-mocha) task
=> Starting Tunnel to Sauce Labs
=> Stopping Tunnel to Sauce Labs
>> 
>> Error closing tunnel

Do contributors need to create a Sauce Labs account to run the tests? Or is something else at play?

[elsehow]

The issue is indeed that contributors need to bring their own Sauce Labs API key.

Specifically, you need to set environment variables before you run the tests, e.g.

SAUCE_USERNAME="your-usrname" SAUCE_ACCESS_KEY="your-access-key" grunt test

I will add this info to the README and do a PR
