Description: # 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:
        ```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):
        
        ```python
            pytest_plugins = ['pytest_profiling']
        ```
        
        ## Usage
        
        Once installed, the plugin provides extra options to pytest:
        
        ```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:
        
        
        ```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:
        
        ```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:
        
        ```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:
        
        ```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.
