1. Green build of the gem on all operating systems. You can see the current build state on [the project page at Travis CI]( You are welcome to improve it.

Our goal is to migrate to [RSpec](

If you write new tests, please do it in RSpec.

You are also welcome to convert existing Test/Unit tests to RSpec.


All work for a next release is done in the `develop` branch. Please create your branch off of it.

Pull Requests

Please choose the `rmagick/rmagick` repo and the `develop` branch as the destination for your pull request.

NOTE: GitHub suggests `rmagick-temp/rmagick` repo by default. **This is incorrect.** Please switch to `rmagick/rmagick`. It should be the next repo in the drop-down list.
