Pytest Profiling Plugin
=======================

Profiling plugin for pytest, with tabular and heat graph output.

Tests are profiled with
`cProfile <http://docs.python.org/library/profile.html#module-cProfile>`__
and analysed with
`pstats <http://docs.python.org/library/profile.html#pstats.Stats>`__;
heat graphs are generated using
`gprof2dot <http://code.google.com/p/jrfonseca/wiki/Gprof2Dot>`__ and
`dot <http://www.graphviz.org/>`__.

Installation
------------

Install using your favourite package installer:

.. code:: bash

        pip install pytest-profiling
        # or
        easy_install pytest-profiling

Enable the fixture explicitly in your tests or conftest.py (not required
when using setuptools entry points):

.. code:: python

        pytest_plugins = ['pytest_profiling']

Usage
-----

Once installed, the plugin provides extra options to pytest:

.. code:: bash

        $ py.test --help
        ...
          Profiling:
            --profile           generate profiling information
            --profile-svg       generate profiling graph (using gprof2dot and dot
                                -Tsvg)

The ``--profile`` and ``profile-svg`` options can be combined with any
other option:

.. code:: bash

        $ py.test tests/unit/test_logging.py --profile

``pstats`` files (one per test item) are retained for later analysis in
``prof`` directory, along with a ``combined.prof`` file:

.. code:: bash

        $ ls -1 prof/
        combined.prof
        test_app.prof
        test_flushing.prof
        test_import.prof

By default the ``pstats`` files are named after their corresponding test
name, with illegal filesystem characters replaced by underscores. If the
full path is longer that operating system allows then it will be renamed
to first 4 bytes of an md5 hash of the test name:

.. code:: bash

        $ ls -1 prof/
        combined.prof
        test_not_longer_than_max_allowed.prof
        68b329da.prof

If the ``--profile-svg`` option is given, along with the prof files and
tabular output a svg file will be generated:

.. code:: bash

        $ py.test tests/unit/test_logging.py --profile-svg
        ...
        SVG profile in prof/combined.svg.

This is best viewed with a good svg viewer e.g. Chrome.
