Project description

pytest-fixture-tools: Pytest fixture tools plugin

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.

You can generate the usage fixture graph like that:

# 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-type=jpg

The output would be like that:
