ruby versions of the query server spec functions
------------------------------------------------
Key: COUCHDB-732
URL: https://issues.apache.org/jira/browse/COUCHDB-732
Project: CouchDB
Issue Type: Improvement
Components: Test Suite
Reporter: Matt Lyon
Priority: Trivial
In the process of creating the a ruby version of the query server, I wrote
these to determine it was working correctly. Even though the repository for the
ruby query server contains its own test suite, I figure these might be welcomed
into the main query server specs. If not, no big deal. They assume the ruby
query server's repository is in the same parent directory as couchdb.
