how to get simplecov results when running specs from zeus.

.simplecov

require 'simplecov'
SimpleCov.configure do
  SimpleCov.refuse_coverage_drop
  add_filter "/spec/"
  add_filter "scraper.rb" # don't care that this is spaghetti code
  add_filter "error_messages_helper.rb"
  add_filter "/config/"
  add_filter "controller"
  SimpleCov.minimum_coverage 93
end

custom_plan.rb

require 'zeus/rails'

class CustomPlan < Zeus::Rails

  def test
    require 'simplecov'
    SimpleCov.start
    # you may need to load other files...
    Dir["#{Rails.root}/app/helpers/**/*.rb"].each { |f| load f }
    super
  end

end

Zeus.plan = CustomPlan.new

spec_helper.rb

def zeus_running?
  File.exists? '.zeus.sock'
end

if !zeus_running?
  SimpleCov.start
end

zeus.json

{
  "command": "ruby -rubygems -r./custom_plan -eZeus.go",

  "plan": {
    "boot": {
      "default_bundle": {
        "development_environment": {
          "prerake": {"rake": []},
          "runner": ["r"],
          "console": ["c"],
          "server": ["s"],
          "generate": ["g"],
          "destroy": ["d"],
          "dbconsole": []
        },
        "test_environment": {
          "test_helper": {"test": ["rspec", "testrb"]}
        }
      }
    }
  }
}

I believe you can also check ENV['ZEUS_MASTER_FD'] to see if it is running inside a zeus process.
