Running Puma on Nginx

I use the latest Puma v1.4.0 from rubygems.

Make sure you have nginx installed with these options:

>/opt/nginx/sbin/nginx -V
nginx version: nginx/1.0.15

Mocha/MiniTest integration

I think that the approach @tenderlove has suggested to avoid monkey-patching MiniTest (and the way MiniTest works) means that to use Mocha with MiniTest, you would either need to include the Mocha integration module into every test case, or define your own test case class inheriting from MiniTest::Unit::TestCase.

This works well for Rails (i.e. ActiveSupport), because it already defines a new test case class (ActiveSupport::TestCase) which is a suitable place to include the Mocha integration module.

If we were to go down this route, in non-Rails Ruby projects you'd need to do one of the following...
