boom 0.5

Installation

Boom! requires Gevent and Requests. If you are under Windows I strongly recommend installing Gevent with the xxx-win32-py2.7.exe installer you will find at: https://github.com/SiteSupport/gevent/downloads

Boom! should work with the latest 1.x version or the latest 0.x version.

If you are under Linux, installing the source version is usually a better idea. You will need libevent for Gevent 0.x and libev for Gevent 1.x.

Example under Ubuntu:

$ sudo apt-get install libevent python-dev

Then:

$ pip install boom

Design

Boom uses greenlets through Gevent to create virtual users, and uses Requests to do the queries.

Using greenlets allows Boom to spawn large amounts of virtual users with very little resources. It’s not a problem to spawn 1000 users and hammer a web application with them.

I plan to add more things like allowing people to provide a callable for the -D option.
