Let’s call this the “interactive RSpec”.

Execute spec file(s) via running IRB session¶ ↑

> irspec 'path/to/spec_file_spec.rb'

The filename parameter matches to various shortcuts such as:

'spec/foo'    => spec/foo_spec.rb
'models/user' => spec/models/user_spec.rb
'controllers' => spec/controllers/**/*_spec.rb
:all          => **/*_spec.rb

How to start¶ ↑

Launch an interactive RSpec console via CLI¶ ↑

% irspec

Launch an interactive RSpec console via running IRB session¶ ↑

> require 'rubygems'
> require 'interactive_rspec'
> irspec

With Rails¶ ↑

Bundle interactive_rspec gem¶ ↑

gem 'interactive_rspec'

% bundle

Start up your Rails console¶ ↑

% rails c

Then it’s done!¶ ↑

You can check how the matchers work:

> irspec
> User.new(:name => 'matz').should_not be_valid

You can run any of the existing spec files:

> irspec 'spec/requests/users_spec.rb'

You might notice that it runs suuuuper fast since irspec uses already loaded Rails process.
