pytest-manifest 1.0rc0

PyTest plugin for recording and asserting against a manifest file

pytest-manifest

pytest-manifest is a plugin for the pytest testing framework. Its purpose is to provide an easy way to capture and assert test outputs.

Installation

To install pytest-manifest, use pip:

pip install pytest-manifest

Usage

pytest-manifest exposes a manifest fixture that loads the expected test result from a YAML file and can be asserted against a test output:

def test(manifest):
    assert manifest == "actual"

...or load a subset of the file using a key:

    assert manifest["key"] == "actual"

The manifest file can optionally be overwritten with the actual test result on failed assertions by passing the --overwrite-manifest/-O flag to pytest when executing tests:

pytest --overwrite-manifest test.py
