SimpleCov reports not generating in Rails 3 app after running RSpec tests with Spork

Question

I just installed the SimpleCov gem to generate code coverage reports on my Rails 3.2.6 app, and it works great with RSpec, just not with Spork. I am able to get the desired

Answer 1

I have this working in a Rails app with these specific versions:

• rails (3.2.8)
• guard (1.3.2)
• guard-spork (1.1.0)
• spork (0.9.2)
• simplecov (0.6.4)
• rspec-rails (2.11.0)

The spec/spec_helper.rb looks like this:

require "spork"

Spork.prefork do

end

Spork.each_run do
  require "simplecov"
  SimpleCov.start "rails"

  ENV["RAILS_ENV"] ||= "test"
  require File.expand_path("../../config/environment", __FILE__)
  require "rspec/rails"
  require "capybara/rspec"

  Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }

  FactoryGirl.reload
end

While it is probably less-than-ideal to require everything in the Spork.each_run block from a performance standpoint, this correctly runs SimpleCov on every test invocation and appears to have relatively low overhead.

I hope that helps. Good luck!
