Visual diff tests for Python
============================

Automate chrome browser render diffs for website testing
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Featuring Puppeteer, headless Chrome and Python image diffing

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

.. code:: bash

    pip install visualdiff

Usage
-----

Create your tests calling ``visualdiff.compare(url)``, this will drive a
headless Chrome session rendering the desired URL and comparing the
resulting image with an expected one.

The expectation are stored by default in a ``visualdiff`` subfolder of
the current calling test script.

There are several additional options you can use, we'll see them in the
examples

.. code:: python

    import visualdiff as vd

    assert not vd.difference('https://example.com')
