Package: pytest-profiling
Profiling plugin for pytest, with tabular and heat graph output.Tests are profiled withcProfileand analysed withpstats;
heat graphs are generated usinggprof2dotanddot.InstallationInstall using your favourite package installer:pipinstallpytest-profiling# oreasy_installpytest-profilingEnable the fixture explicitly in your tests or conftest.py (not required
when using setuptools entry points):pytest_plugins=['pytest_profiling']UsageOnce installed, the plugin provides extra options to pytest:$py.test--help...Profiling:--profilegenerateprofilinginformation--profile-svggenerateprofilinggraph(usinggprof2dotanddot-Tsvg)The--profileandprofile-svgoptions can be combined with any
