- Jasmine is currently incompatible with rspec 2.11.0 due to some DSL changes. The rspec formatting is being rewritten, but for now we'll need rspec <= 2.10.0
- 1.9.3 compatible; much simpler. Probably won't work with older rubies, but good enough for most development.
- No longer used now that we're on Travis
Use RSpec 2.x if it's available. Rails 3.x generators don't work.
Don't require json and thin; these gems have native components and cannot be installed under JRuby. Instead, make json a runtime-only requirement, and use the default Rack::Server rather than thin.
