ATTENTION
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 at Funkload or Locust.
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.
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/surfly/gevent/downloads
Boom! 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-dev
Then:
$ pip install boom
Basic 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. Starting the load [===================================] Done -------- Results -------- Successful calls 100 Total time 0.3260 s Average 0.0192 s Fastest 0.0094 s Slowest 0.0285 s Amplitude 0.0191 s RPS 306 BSI Pretty good -------- Legend -------- RPS: Request Per Second BSI: Boom Speed Index
Boom! has more options:
$ boom --help usage: boom [-h] [--version] [-m {GET,POST,DELETE,PUT,HEAD,OPTIONS}] [--content-type CONTENT_TYPE] [-D DATA] [-c CONCURRENCY] [-a AUTH] [--header HEADER] [--pre-hook PRE_HOOK] [--post-hook POST_HOOK] [--json-output] [-n REQUESTS | -d DURATION] [url] Simple HTTP Load runner. positional arguments: url URL to hit optional arguments: -h, --help show this help message and exit --version Displays version and exits. -m {GET,POST,DELETE,PUT,HEAD,OPTIONS}, --method {GET,POST,DELETE,PUT,HEAD,OPTIONS} HTTP Method --content-type CONTENT_TYPE Content-Type -D DATA, --data DATA Data. Prefixed by "py:" to point a python callable. -c CONCURRENCY, --concurrency CONCURRENCY Concurrency -a AUTH, --auth AUTH Basic authentication user:password --header HEADER Custom header. name:value --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 seconds
You can trigger load testing from Python code by importing the function boom.boom.load directly, as follows:
from boom.boom import load result = load('http://example.com/', 1, 1, 0, 'GET', None, 'text/plain', None, quiet=True)
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.
