I'm using ruby version managers so I can easily switch between ruby 1.9 and ruby 1.8.7. The speed difference happens in both production and developmen...

Is there some way to change Rails environments mid-way through a test? Or, alternately, what would be the right way to set up a test suite that can start up Rails in one environment, run the first half of my test in it, then restart Rails in another environment to finish the test? The two environments have separate databases. Some neces...
