Migrating Rails app: which version of Rspec next?

[Jack Royal-Gordon]

I’ve been working on migrating my Rails app and I’m currently up to Ruby 2.0, Rails 4.0, RSpec 2.99. I want to move to the latest version of RSpec that will work with the current Ruby/Rails environment, and provide a springboard form where I can continue upgrading Ruby and Rails.

Two questions:
1) Should I be migrating one minor RSpec version at a time, as they recommend for Rails, or can I just make the jump to my eventual target?
2) Would the target version be 3.9, as the changlog for rspec-rails seems to indicate (4.0 drops support for Rails 4, and I can’t find anything about any other versions terminating support for either Ruby or Rails)?

Hello!

1) I would go straight to 3.9 for RSpec, the whole 3.x series should be 100% compatible with 3.0.0 so you should be fine once you’ve gotten 2.99 into an upgrade ready state. If its not a straight forward pass when you do that, I would check 3.0.0 passes, but really you should have no issues.

2) I would not upgrade to rspec-rails 4.0 until you are ready to upgrade Rails to 5.x at least. We do soft support Rails 4.2 on rspec-rails 4.0 but your life will be easier if you have upgraded Rails first.

Cheers

Jon
