Simplified test-queue runner with simplecov

test-queue.rb

#!/usr/bin/env ruby

require 'test_queue'
require 'test_queue/runner/rspec'

class MyAppTestRunner < TestQueue::Runner::RSpec
  def after_fork(num)
    SimpleCov.command_name "worker#{num}"
    ActiveRecord::Base.configurations['test']['database'] << num.to_s
    ActiveRecord::Base.establish_connection(:test)
  end

  # initialize
  def prepare(concurrency)
    1.upto(concurrency) do |i|
      ActiveRecord::Tasks::DatabaseTasks.drop_current
      ActiveRecord::Tasks::DatabaseTasks.create_current
      ActiveRecord::Tasks::DatabaseTasks.load_schema_current
      # master doesn't need connection
      ActiveRecord::Base.connection.disconnect!
    end
  end

  def cleanup_worker
    # record each worker's result
    SimpleCov.result
  end

  def summarize
    # output result
    SimpleCov.at_exit.call
  end
end

MyAppTestRunner.new.execute

for some reason I had to define SimpleCov.at_exit outside of SimpleCov.start {} to make it defined as I wanted.

(I guess it's simplecov's matter, nothing to do with tmm1/test-queue#35 )
