/**
 * The GitBlitSuite uses test-gitblit.properties and test-users.conf. The suite
 * is fairly comprehensive for all lower-level functionality. Wicket pages are
 * currently not unit-tested.
 * 
 * This suite starts a Gitblit server instance within the same JVM instance as
 * the unit tests. This allows the unit tests to access the GitBlit static
 * singleton while also being able to communicate with the instance via tcp/ip
 * for testing rpc requests, federation requests, and git servlet operations.
