Profiling

Profile test execution using hotshot.

This plugin implements startTestRun() and replaces event.executeTests with hotshot.Profile.runcall(). It implements beforeSummaryReport() to output profiling information before the final test summary time. Config file options filename, sort and restrict can be used to change where profiling information is saved and how it is presented.

Load this plugin by running nose2 with the –plugin=nose2.plugins.prof option and activate it with the –profile option,or put the corresponding entries (plugin and always_on) in the respective sections of the configuration file.
