Overview

Defines a Rake task for running features.

The simplest use of it goes something like:

Cucumber::Rake::Task.new

This will define a task named cucumber described as 'Run Cucumber features'. It will use steps from 'features/*/.rb' and features in 'features/*/.feature'.

To further configure the task, you can pass a block:

Cucumber::Rake::Task.new do |t|
  t.cucumber_opts = %w{--format progress}
end

See the attributes for additional configuration possibilities.

#binaryObject

Name of the cucumber binary to use for running features. Defaults to Cucumber::BINARY

def binary
  @binary
end

#bundlerObject

Whether or not to run with bundler (bundle exec). Setting this to false may speed up the execution. The default value is true if Bundler is installed and you have a Gemfile, false otherwise.

Note that this attribute has no effect if you don't run in forked mode.

end

#cucumber_optsObject

Extra options to pass to the cucumber binary. Can be overridden by the CUCUMBER_OPTS environment variable. It's recommended to pass an Array, but if it's a String it will be #split by ' '.

def cucumber_opts
  @cucumber_opts
end

#forkObject

Whether or not to fork a new ruby interpreter. Defaults to true. You may gain some startup speed if you set it to false, but this may also cause issues with your load path and gems.
