pytest-shutil 1.6.0

A goodie-bag of unix shell and environment tools for py.test

This library is a goodie-bag of Unix shell and environment management tools for automated tests. A summary of the available functions is below, look at the source for the full listing.

Installation

Install using your favourite package manager:

.. code:: bash

pip install pytest-shutil # or.. easy_install pytest-shutil

Workspace Fixture

The workspace fixture is simply a temporary directory at function-scope with a few bells and whistles:

.. code:: python

# Enable the fixture explicitly in your tests or conftest.py (not required when using setuptools entry points) pytest_plugins = [‘pytest_shutil’]

def test_something(workspace):

# Workspaces contain a handle to the path.py path object (see https://pathpy.readthedocs.io/) path = workspace.workspace script = path / ‘hello.sh’ script.write_text(‘#!/bin/shn echo hello world!’)

# There is a ‘run’ method to execute things relative to the workspace root workspace.run(‘hello.sh’)
