cherrypy.test.benchmark module

CherryPy Benchmark Tool.

Usage:

benchmark.py [options]

–null: use a null Request object (to bench the HTTP server only) –notests: start the server but do not run the tests; this allows

you to check the tested pages with a browser

–help: show this help message –cpmodpy: run tests via apache on 54583 (with the builtin _cpmodpy) –modpython: run tests via apache on 54583 (with modpython_gateway) –ab=path: Use the ab script/executable at ‘path’ (see below) –apache=path: Use the apache script/exe at ‘path’ (see below)

To run the benchmarks, the Apache Benchmark tool “ab” must either be on your system path, or specified via the –ab=path option.

To run the modpython tests, the “apache” executable or script must be on your system path, or provided via the –apache=path option. On some platforms, “apache” may be called “apachectl” or “apache2ctl”–create a symlink to them if needed.

Bases: object

A session of ‘ab’, the Apache HTTP server benchmarking tool.
