Perforat

Perforat monitors your tests and notice in case some of them significant slowed down.

Installation

Add this line to your application's Gemfile:

gem 'perforat'

And then execute:

$ bundle

Or install it yourself as:

$ gem install perforat

Then you need to require it on your rails_helper or spec_helper

require 'perforat'

As each test running takes different time to run there are some settings to tune it:

:results_count,    default: 20   # how much notification can be displayed
:minimal_duration, default: 0.1  # in case of your tests are really fast they produce really huge coefficients event without any changes, minimal_duration` uses to minimal false positive activation.
:minimal_epsilon,  default: 0.1  # in case of test takes acceptable time it can be not so slowed down to notify about it
:keep_files,       default: 2    # **Perforat** need only last two files to see difference between tests duration, so if you need more -- you always can change this setting

To configure it add you need to pass params to RSpec settings

RSpec.configure do |config|
  config.perforat = { keep_files: 5 }
end

Development
