A simple plugin to use with pytest

----

This `pytest`_ plugin was generated with `Cookiecutter`_ along with `@hackebrot`_'s `cookiecutter-pytest-plugin`_ template.


Features
--------

* Readable diffs for failed tests
* Customizable diffs for your classes


Requirements
------------

* `pytest`
* `deepdiff`


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

You can install "pytest-diff" via `pip`_ from `PyPI`_::

$ pip install pytest-diff


Usage
-----


.. code-block:: python
class Person:
def __init__(self, name, age, favorites):
self.name = name
self.age = age
self.favorites = favorites


def test_person():
a = Person("Alice", age=21, favorites={"food": "spam", "movie": "Life of Brian"})
b = Person("Alice", age=21, favorites={"food": "eggs", "movie": "Life of Brian"})
assert a == b


Running `pytest` gives:


.. code-block:: python
______________________________ test_person ______________________________

def test_person():
a = Person("Alice", age=21, favorites={'food': 'spam', 'movie': 'Life of Brian'})
b = Person("Alice", age=21, favorites={'food': 'eggs', 'movie': 'Life of Brian'})
> assert a == b
E assert
E <test_person.Person object at 0x7fa326d769e8>
E ==
E <test_person.Person object at 0x7fa326d76be0>
E {'values_changed': {"root.favorites['food']": {'new_value': 'spam', 'old_value': 'eggs'}}}
