You may experience issues testing multiple plugins at once when using
the code-mixing features that the engines plugin provides. If you do
experience any problems, please test plugins individually, i.e.
 
  $ rake test:plugins PLUGIN=my_plugin
 
or use the per-type plugin test tasks:
 
  $ rake test:plugins:units
  $ rake test:plugins:functionals
  $ rake test:plugins:integration
  $ rake test:plugins:all
 
Report any issues on http://dev.rails-engines.org. Thanks!
