Package: boom
Boom!is a simple command line tool to send some load to a web app.Boom! is a script you can use to quickly smoke-test your
web app deployment. If you need a more complex tool,
I’d suggest looking atFunkloadorLocust.Boom! was specifically written to replace my Apache Bench usage,
to provide a few missing features and fix a few annoyances I had
with AB.I have no special ambitions for this tool, and since I have not
found any tool like this in the Python-land, I wrote this one.There are a lot of other tools out there, like Siege which
seems very popular.However, Boom! is a good choice because it works on any platform
and is able to simulate thousands of users by using greenlets.InstallationBoom! requiresGeventandRequests. If you are under Windows
I strongly recommend installing Gevent with thexxx-win32-py2.7.exeinstaller you will find  at:https://github.com/surfly/gevent/downloadsBoom! should work with the latest versions.If you are under Linux, installing the source version is usually a better
idea. You will need libev for Gevent.Example under Ubuntu:$ sudo apt-get install libev libev-dev python-devThen:$ pip install boomBasic usageBasic usage example: 100 queries with a maximum concurrency of
10 users:$ boom http://localhost:80 -c 10 -n 100
Server Software: nginx/1.2.2
Running 100 queries - concurrency: 10.

  --pre-hook PRE_HOOK   Python module path (eg: mymodule.pre_hook) to a
                        callable which will be executed before doing a request
                        for example: pre_hook(method, url, options). It must
                        return a tupple of parameters given in function
                        definition
  --post-hook POST_HOOK
                        Python module path (eg: mymodule.post_hook) to a
                        callable which will be executed after a request is
                        done for example: eg. post_hook(response). It must
                        return a given response parameter or raise an
                        `boom.boom.RequestException` for failed request.
  --json-output         Prints the results in JSON instead of the default
                        format
  -n REQUESTS, --requests REQUESTS
                        Number of requests
  -d DURATION, --duration DURATION
                        Duration in secondsDesignBoom uses greenlets through Gevent to createvirtual 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.If you are interested in this project, you are welcome to join the fun athttps://github.com/tarekziade/boomMake sure to add yourself to the contributors list if your PR gets merged.
