Travis build matrix for Rails
Do you have a gem that needs to test against multiple versions of Rails? Doing it all can be complex, and while I have lots to say about this topic, but here's one of the pieces: Travis build matrix.
Here's what you want:
language: ruby rvm: - 1.8.7 - 1.9.2 - 1.9.3 - 2.0.0 - ruby-head env: - "RAILS_VERSION=3.2" - "RAILS_VERSION=3.1" - "RAILS_VERSION=3.0" - "RAILS_VERSION=master" matrix: allow_failures: - rvm: ruby-head - env: "RAILS_VERSION=master" exclude: - rvm: 2.0.0 env: "RAILS_VERSION=3.0" - rvm: 2.0.0 env: "RAILS_VERSION=3.1" - rvm: 1.8.7 env: "RAILS_VERSION=master" - rvm: 1.9.2 env: "RAILS_VERSION=master" - rvm: ruby-head env: "RAILS_VERSION=3.0" - rvm: ruby-head env: "RAILS_VERSION=3.1"
Here's what all this does:
- 1.8.7 and 1.9.2 is supported across all of the 3.x series, but not master
- 2.0.0 is supported on Rails 3.2 (as of the upcoming 3.2.13, but it will probably work with your gem with 3.2.12) and master, but not 3.0 or 3.1.
- We want to allow failures on ruby-head, because it's not likely to be stable
- We also want to allow failures for Rails master, because sometimes it's not stable either
- ruby-head should only be built against master
