title: Mongoose open connection issue with Supertest
body: <p>I am unable to run multiple Supertest/Mocha tests as I get an error <code>Error: Trying to open unclosed connection.</code> - I found this <a href="http://www.scotchmedia.com/tutorials/express/authentication/2/02" rel="nofollow">post</a> which suggest looping and checking connection status. Wondering if there is a better way? perhaps something that was added in Supertest recently to handle this.</p>
