nose-performance
A performance testing plugin for Nose. It's primary goal is to monitor calls to network applications, such as the database and memcache.
Integrates with Zumanji to report and archive results.
Usage
Create some tests which inherit from PerformanceTest
:
from noseperf.testcases import PerformanceTest class MyTest(PerformanceTest): def test_redis(self): client = Redis() for x in xrange(2 ** 16): client.add('test-%x' % x, '1')
Run your test suite with the --with-performance
option:
$ python runtests.py --with-performance example/
(We're using runtests.py because we inject django-nose to test our Django hooks)
Results are recorded to test_results/performance.json
by default:
$ ls -lh test_results total 2128 -rw-r--r-- 1 dcramer staff 1.0M Aug 27 18:10 performance.json
See the included tests in example/
and nosetests --help | grep performance
for more information.
Test Cases
The plugin will only collect tests which inherit from PerformanceTest
. Included are two simple test cases,
one for generic installs, and one for Django:
- noseperf.testcases.PerformanceTest
- noseperf.testcases.DjangoPerformanceTest
Captured Data
Currently the data captured includes hooks for the following:
- Redis
- Django ORM
- Django Cache
- Django Templates
About
This plugin was originally created at DISQUS by Zameer Manji as an experiment in automating testing for performance regressions.
Some of the hooks have been inspired by work done in various applications, such as Sentry and Django Debug Toolbar.
