Is your team trying to do TDD and failing? Are you finding your test suites bloated and difficult to read, understand, or maintain? Business applications today are plagued with features that are never used, highly coupled code that is hard to change, and expensive test suites that aren’t run any more because they are brittle and unreadable.

RSpec, Ruby’s leading Behaviour Driven Development tool, helps you do TDD right by embracing the design and documentation aspects of TDD. It encourages readable, maintainable suites of code examples that not only test your code, they document it as well. The RSpec Book will teach you how to use RSpec, Cucumber, and other Ruby tools to develop truly agile software that gets you to market quickly and maintains its value as evolving market trends drive new requirements.

If your TextMate is:

• using the Ruby Bundle for files that are Ruby on Rails;
• using the Ruby on Rails Bundle for files that are Rspec;
• any other wrong association.

There are some ways to fix. I followed these steps to fix it:

1. Remove the manual associations. When you use the popup bar at the status bar, in Textmate, you may not know but you are associating files to Bundles, manually, which is bad. To fix it, let’s first read what’s already in there. Run this command in the Terminal:

defaults read com.macromates.textmate OakLanguageFileBindings

Check the manual associations you’ve made so far. And remove them all with:

defaults delete com.macromates.textmate OakLanguageFileBindings

2. Specify inside a Bundle, which files it should be used for. Open Bundles → Bundle Editor → Edit Languages… and locate the Ruby Grammar. Inside this text area, locate a line that looks like this:

fileTypes = ( 'rb', 'rbx', 'rjs', 'Rakefile', 'rake',
  'cgi', 'fcgi', 'gemspec', 'irbrc', 'capfile' );

Remove the rb extension. And add it to the Ruby on Rails grammar instead. At the end my lines became like this:

# my Ruby Language grammar
fileTypes = ( 'rbx', 'rjs', 'Rakefile', 'rake', 
  'cgi', 'fcgi', 'gemspec', 'irbrc', 'capfile' );

# my Ruby on Rails Language grammar
fileTypes = ( 'rb', 'rxml', 'builder' );

As you see, the rb extension now belongs to the Rails Language Grammar.

Now whenever I open a *.rb file, the Bundle is Ruby on Rails. Whenever I open a *_spec.rb file, the Bundle is RSpec. You can always improve on that idea, and do what you think it’s best for you. For example, you can edit Ruby on Rails grammar for .erb files, .rjs, and the like.
