Functional and load web tester.

Project description

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, like checking if a site is alive.

Main FunkLoad features are:

  • FunkLoad is free software distributed under the GNU GPL.

  • 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 Richard Jones’ webunit:

    • basic authentication support

    • cookies support

    • referrer support

    • http proxy support

    • fetching css, javascript and images

    • emulating a browser cache

    • file upload and multipart/form-data submission

    • https support

  • 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

    • green/red color mode

    • select test case 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.

  • Detailed bench reports in ReST or HTML (and PDF via ps2pdf) containing:

    • the bench configuration

    • tests, pages, requests stats and charts with percentiles.

    • the 5 slowest requests.

    • servers cpu usage, load average, memory/swap usage and network traffic charts.

    • an http error summary list

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

  • Easy test creation using TCPWatch as proxy recorder, so you can use your web browser and produce a FunkLoad test automatically.

  • Provides web assertion helpers.

  • Provides a funkload.CPSTestCase to ease Zope and Nuxeo CPS testing.

  • Easy to install (EasyInstall) and use, see examples in the demo folder.
