Warnings when running rake test

[chrisvel]

I am using Apache CouchDB 1.6.1 and while trying to rake test, all of my tests pass but I have some warnings at the top:

/usr/local/lib/ruby/gems/2.3/gems/couchrest-2.0.0/lib/couchrest/connection.rb:119: warning: instance variable @http not initialized
/usr/local/lib/ruby/gems/2.3/gems/couchrest-2.0.0/lib/couchrest/database.rb:194: warning: assigned but unused variable - ids
/usr/local/lib/ruby/gems/2.3/gems/couchrest-2.0.0/lib/couchrest/document.rb:25: warning: method redefined; discarding old database
/usr/local/lib/ruby/gems/2.3/gems/couchrest-2.0.0/lib/couchrest/support/inheritable_attributes.rb:55: warning: previous definition of database was here
/usr/local/lib/ruby/gems/2.3/gems/couchrest-2.0.0/lib/couchrest/document.rb:25: warning: method redefined; discarding old database=
/usr/local/lib/ruby/gems/2.3/gems/couchrest-2.0.0/lib/couchrest/support/inheritable_attributes.rb:85: warning: previous definition of database= was here
/usr/local/lib/ruby/gems/2.3/gems/couchrest-2.0.0/lib/couchrest/document.rb:90: warning: method redefined; discarding old database

I currently suppress them by adding $VERBOSE=nil to my test_helper.rb file but this is not an actual solution.

Please keep in mind that I have and use a list of other gems too but they're the only warnings I get when running "rake test". Any ideas where the issue might be ?
