pytest-canonical-data
A plugin which allows to compare results with canonical results, based on previous runs.
Inspired by Yandex’s canondata plugin, pytest-needle and pytest-regtest.
This pytest plugin was generated with Cookiecutter along with @hackebrot’s cookiecutter-pytest-plugin template.
TODO
Implement pytest’s hooks for asserts
Use pytest’s asserts for comparing objects
Driver for images
Driver for json
HTML reports for images
Installation
You can install “pytest-canonical-data” via pip from PyPI:
$ pip install pytest-canonical-data
Usage
Plugin provides canonical_data fixture, which allows to create canonical results:
def test_sth(canonical_data):
# creates canonical result object with name `result.txt` and `text` driver
canonical_result = canonical_data('result.txt', 'text')
# In default mode will compare saved canonical result with `123` string
# In canonize mode will save `123` as the canonical result
canonical_result.assert_equal('123')
To run in canonize mode execute:
pytest --canonize
It will create files with canonical results (if don’t exist) and save actual results.
Drivers
You need to use appropriate driver for each data type. Currently, there are the following drivers:
bytes: for comparing bytes sequences.
str: for comparing python strings.
text: alias for the str driver.
