Usage

show-fixture-duplicates
***********************

If you have already installed ``pytest-fixture-tools`` plugin then you can use one of its commands.

``--show-fixture-duplicates`` - will collect all fixtures and print you a list of duplicates for each fixture.

With ``--show-fixture-duplicates`` you can use ``--fixture name_of_fixture`` option to get list of duplicates only for specific fixture

.. sourcecode::

    py.test tests/ --show-fixture-duplicates --fixture order

Output can look like this:

.. sourcecode::

fixture-graph
*************

You can generate the usage fixture graph like that:

.. sourcecode:: bash

    # on windows gitbash as example
    export PATH=$PATH:/c/Program\ Files\ \(x86\)/Graphviz2.38/bin/
    pytest --fixture-graph -s

    # or you can select the output direcotry like that:
    pytest --fixture-graph --fixture-graph-output-dir=./test_output

    # you can also change the output type of the graphs (any of graphvis supported outputs types):
    pytest --fixture-graph --fixture-graph-output-type=jpg

The output would be like that:

.. sourcecode::
