The pytest-fixture-tools package is a pytest plugin which provides various tools for fixture.
pip install pytest-fixture-tools
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
py.test tests/ --show-fixture-duplicates --fixture order
Output can look like this:
========================================== test session starts ========================================== platform linux2 -- Python 2.7.3 -- pytest-2.5.1 -- /home/batman/.virtualenvs/arkham-city/bin/python Tests are shuffled using seed number 355495648184. cachedir: /home/batman/.virtualenvs/arkham-city/.cache plugins: fixture-tools, random, bdd-splinter, pep8, cov, contextfixture, bdd, xdist, instafail, cache collected 2347 items / 1 skipped

You can generate the usage fixture graph like that:
bash
# on windows gitbash as example export PATH=$PATH:/c/ProgramFiles(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-type=jpg
The output would be like that:
