empty reports under test-loop

[sunaku]

Hello,

I'm getting empty reports (no files listed; all sections 100% coverage) when running my Rails 3.0.7 app's test suite in parallel with test-loop and SimpleCov 0.4.2. This problem was also described previously in issue #30.

I tried the following ways of invoking SimpleCov in my test suite.

Starting SimpleCov at the top of my test/test_helper.rb in the master process:

require 'simplecov'
SimpleCov.start 'rails'

ENV["RAILS_ENV"] = "test"
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'

Test::Loop.before_each_test.push lambda {
  |test_file, log_file, test_names|

  SimpleCov.root File.dirname(log_file)
  SimpleCov.coverage_dir File.basename(test_file) + '.cov'
}

Starting SimpleCov in a worker process just before it loads and runs a test/**_test.rb file from my Rails app test suite:

ENV["RAILS_ENV"] = "test"
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'

Test::Loop.before_each_test.push lambda {
  |test_file, log_file, test_names|

  require 'simplecov'
  SimpleCov.start 'rails'
  SimpleCov.root File.dirname(log_file)
  SimpleCov.coverage_dir File.basename(test_file) + '.cov'
}

Starting SimpleCov (after configuring its output locations) in a worker process just before it loads and runs a test/**_test.rb file from my Rails app test suite:

ENV["RAILS_ENV"] = "test"
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'

Test::Loop.before_each_test.push lambda {
  |test_file, log_file, test_names|

  require 'simplecov'
  SimpleCov.root File.dirname(log_file)
  SimpleCov.coverage_dir File.basename(test_file) + '.cov'
  SimpleCov.start 'rails'
}

None of these worked; I always get empty reports. Any ideas?

Thanks for your consideration.

I think this issue might be related to the stuff I wrote about using SimpleCov with Spork over at #42 - could you please have a look there and check out whether there's a way to load simplecov before your whole app's environment is loaded on each run?

Idle timeout. Please re-open when neccessary.

After watching @tenderlove's Hidden Gems of Ruby 1.9 presentation, I rolled my own coverage reporting for Ruby 1.9+. So this request is no longer necessary. Cheers.
