LoadaBoy

Synopsis

A Load Tester that allows you to generate dynamic requests.

Requirements

LoadaBoy requires Erlang and RubyGems.

Installation

gem install loadaboy

How it works

Write a custom generator in Loadafile.rb:

Write a generator containing each request a worker needs to perform per job. The request order is respected. You can optionally give a name to the generator if you want to test different load profiles.

In the same folder as your Loadafile.rb, run:

loadaboy domain-name number-of-workers number-of-jobs-per-worker (generator-name)

Example

Loadafile.rb:

require 'loadaboy'

def random_string(n = 10)
  (1..n).map{ ('a'..'z').to_a[rand(26)] }.join
end

def random_keywords(n = 20)
  (1..n).map{random_string(5+rand(20))}.join("+")
end

LoadaBoy.generator do
  request :static,  "/static"
  request :dynamic, "/dynamic/#{rand(3)}?random_string=#{random_string}&keywords=#{random_keywords}"
end

LoadaBoy.generator :only_dynamic do
  request :dynamic, "/dynamic/#{rand(3)}?random_string=#{random_string}&keywords=#{random_keywords}"
end

Run:

loadaboy http://localhost:3000 10 10

loadaboy http://localhost:3000 10 10 only_dynamic

TODO

Add options to request to customize timeout, disable keepalive etc…

Note on Patches/Pull Requests

Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don’t break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
