multi\_rails version 0.0.4 has been released!

- [http://multi-rails.rubyforge.org/](http://multi-rails.rubyforge.org/)

#### MultiRails

```
by Relevance, http://thinkrelevance.com
   Rob S. - MultiRails lead

```

MultiRails lets you test your Rails plugin or app against many  
versions of Rails in one sweep.

#### DESCRIPTION:

MultiRails allows easy testing against multiple versions of Rails for  
your Rails specific gem or plugin. It also has tentative support  
testing Rails applications against multiple versions of Rails.

Use MultiRails to hook in Rails 2.0 testing in your continuous  
integration. Still working on Rails 2.0 support? Use MultiRails to  
see where your test suite falls down against the 2.0 preview releases  
of Rails.

MultiRails was initially developed by members of Relevance while  
developing Streamlined against edge Rails. To see how Streamlined  
uses MultiRails, go to [http://trac.streamlinedframework.org](http://trac.streamlinedframework.org).

#### FEATURES:

- easily test plugins/extensions using a require from your  
test\_helper.rb and a require in your RakeFile
- rake tasks to test against a specified version of Rails, the latest  
version, or all versions
- tentative support for testing plain Rails apps against multiple  
versions of Rails
- Uses rubygems for version management of Rails

#### TODOs:

- improve docs on how to override what files are required by multi\_rails
- maybe add ability to load plain Rails versions – ie checked out  
copies not in RubyGems

#### NOTES:

- ( **For Rails apps only** ) multi\_rails will rename your vendor/rails  
directory to vendor/rails.off if it finds one within your rails app.  
We have to do this to make Rails fall back to RubyGems rails.  
Multi\_rails will rename back to the correct vendor/rails when done  
testing, so it will not interrupt your app in normal use.
- ( **For Rails apps only** ) multi\_rails needs to add a line to top of  
your environment.rb to hook into – see the instructions below for  
more details

Changes:

## 0.0.4

- Change the all task so that the build will run through all rails  
versions, even if one of them fails, but at the end  
the failing versions are printed and we abort. Thanks to Evan  
Weaver for initial patch and idea.

- display the rails gem from the load path as a sanity check right  
after we gem/require

- add autotest railsplugin discovery, so I can use autotest to test  
multi\_rails

- various rake tweaks to make release easier and more automated
