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
