A plugin to use approvaltests with pytest

---

This pytest plugin was generated with Cookiecutter along with @hackebrot’s cookiecutter-pytest-plugin template.

Features

Configure approvaltests for use with pytest.

• indicate which of the reporters to use on test failure

• define your own diff reporter to use on test failure

Requirements

approvaltests

Installation

You can install “pytest-approvaltests” via pip from PyPI:

$ pip install pytest-approvaltests

Usage

See also the documentation for approval tests

When your approval tests fail and you are working interactively, you might like it to open another diff tool than when you are on a CI server for example.

This plugin allows you to configure pytest with which diff tool to use when tests fail.

To set the default reporter to ‘PythonNative’, suitable for use on the command line:

pytest –approvaltests-use-reporter=’PythonNative’

To define your own diff reporter, perhaps a program with a rich GUI installed only on your developer workstation:

pytest –approvaltests-add-reporter=”diff_program”

The value for ‘approvaltests-add-reporter’ should be an executable program that can diff two files received as arguments on the command line like this:

diff_program filepath1 filepath2

if it takes additional arguments, add them with ‘approvaltests-add-reporter-args’:

pytest –approvaltests-add-reporter=”diff_program” –approvaltests-add-reporter-args=”arg1,arg2”

They will be inserted like this:

diff_program arg1 arg2 filepath1 filepath2
