How to setup Cucumber, Guard & Spork with Rails 3.1?

I'm trying to setup cucumber, rspec, guard and spork. I've got rspec working fine but cucumber crashes with the trace below.

I've try setting this up several times, rails g cucumber:install --spork spork cucumber --boostrap etc... with no luck.

Gems: rails (3.1.3) guard (0.10.0) guard-bundler (0.1.3) guard-cucumber (0.7.4, 0.7.3) guard-rails (0.0.3) guard-rspec (0.6.0, 0.5.2) guard-spork (0.5.1, 0.5.0) cucumber (1.1.4) cucumber-rails (1.2.1) spork (0.9.0)

Done.
Solution

  • I finally solved this, after playing around with flags passed to cucumber via my guardfile I was able to resolve conflicting flags and not overriding my cucumber.yml flags.

    Working Guardfile

    guard 'cucumber', :cli => "--drb" do
  watch(%r{^features/.+\.feature$})
  watch(%r{^features/support/.+$})          { 'features' }
  watch(%r{^features/step_definitions/(.+)_steps\.rb$}) { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'features' }
end

    cucumber.yml

    <%
rerun = File.file?('rerun.txt') ? IO.read('rerun.txt') : ""
rerun_opts = rerun.to_s.strip.empty? ? "--format #{ENV['CUCUMBER_FORMAT'] || 'progress'} features" : "--format #{ENV['CUCUMBER_FORMAT'] || 'pretty'} #{rerun}"
std_opts = "--format #{ENV['CUCUMBER_FORMAT'] || 'pretty'} --strict --tags ~@wip"
%>
default: --drb <%= std_opts %> features
wip: --drb --tags @wip:3 --wip features
rerun: --drb <%= rerun_opts %> --format rerun --out rerun.txt --strict --tags ~@wip

    Conflicting Guardfile

    guard 'cucumber', :cli => "--drb --color --format pretty" do
  watch(%r{^features/.+\.feature$})
  watch(%r{^features/support/.+$})          { 'features' }
  watch(%r{^features/step_definitions/(.+)_steps\.rb$}) { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'features' }
end
