Assert Performs

This is a single Test::Unit assertion written to test performance of a Rails action. Meant to be run on staging before production deploys.

Usage

class PerformanceTest < Test::Unit::TestCase
  self.performance_server = "staging.example.com"
  context "a GET to users/1" do
    should "be performant" do
      assert_performs :get, user_path, :rate        => 3,
                                       :timeout     => 5
                                       :id          => 1  # extra params
    end
  end
end

• a path

• a threshold request rate (req/s)

• a timeout (in seconds)
