Appraisal is a Ruby library that integrates with Bundler and Rake to test your library against different versions of its dependencies in repeatable scenarios. It generates per-appraisal Gemfiles so you can run your test suite against multiple dependency versions, such as several Rails releases.
Use cases
- test my ruby gem against multiple rails versions
- check for regressions across dependency versions
- run my test suite with different gemfile configurations
- maintain compatibility with older dependency versions
- set up repeatable bundler scenarios for gem testing
When to choose
- you maintain a Ruby gem or library and need to support multiple dependency versions
- you want to catch regressions against older versions of Rails or other gems
- you already use Bundler and Rake in your test workflow
When to avoid
- you are building an application rather than a reusable library
- you need to vendor gems locally or bundle to a non-global namespace, which is unsupported
- you only test against a single dependency version
