Introduction

FunkLoad_ is a functional and load web tester, written in Python, whose main use cases are:

• Functional testing of web projects, and thus regression testing as well.

• Performance testing: by loading the web application and monitoring your servers it helps you to pinpoint bottlenecks, giving a detailed report of performance measurement.

• Load testing tool to expose bugs that do not surface in cursory testing, like volume testing or longevity testing.

• Stress testing tool to overwhelm the web application resources and test the application recoverability.

• Writing web agents by scripting any web repetitive task.

Features

Main FunkLoad_ features are:

• Functional test are pure Python scripts using the pyUnit_ framework like normal unit test. Python enable complex scenarios to handle real world applications.

• Truly emulates a web browser (single-threaded) using an enhanced Richard Jones' webunit_:

  • get/post/put/delete support
  • post any kind of content type like application/xml
  • DAV support
  • basic authentication support
  • file upload and multipart/form-data submission
  • cookies support
  • referrer support
  • accept gzip content encoding
  • https support
  • https with ssl/tls by providing a private key and certificate (PEM formatted)
  • http_proxy support
  • fetching css, javascript and images
  • emulating a browser cache

• Advanced test runner with many command-line options:

  • set the target server url
  • display the fetched page in real time in your browser
  • debug mode to display http headers
  • check performance of a single page (or set of pages) inside a test
  • green/red color mode
  • select or exclude tests cases using a regex
  • support normal pyUnit_ test
  • support doctest_ from a plain text file or embedded in python docstring

• Turn a functional test into a load test: just by invoking the bench runner you can identify scalability and performance problems. If needed the bench can distributed over a group of worker machines.

• Detailed bench reports in ReST, HTML, Org-mode_, PDF (using LaTeX/PDF Org-mode export) containing:

  • the bench configuration
  • tests, pages, requests stats and charts
  • the requets that took the most time
  • monitoring one or many servers cpu usage, load average, memory/swap usage and network traffic charts
  • an http error summary list

• Differential reports to compare 2 bench reports giving a quick overview of scalability and velocity changes.

• Trend reports to view the performance evolution with multiple reports.

• Easy test customization using a configuration file or command line options.

• Easy test creation using embeded TCPWatch_ as proxy recorder, so you can use your web browser and produce a FunkLoad_ test automatically, including file upload or any ajax call.

• Provides web assertion helpers to check expected results in responses.

• Provides helpers to retrieve contents in responses page using DOM.

• Easy to install (EasyInstall_).

• Comes with examples look at the demo_ folder.

• Successfully tested with dozen of differents web servers: PHP, python, Java...
