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

Project Description
# pytest-shutil

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::

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::

# Enable the fixture explicitly in your tests or (not required when using setuptools entry points)
pytest_plugins = ['pytest_shutil']

def test_something(workspace):
# Workspaces contain a handle to the path object (see
path = workspace.workspace
script = path / ''
script.write_text('#!/bin/sh\n echo hello world!')

# There is a 'run' method to execute things relative to the workspace root'')

## ``pytest_shutil.env``: Shell helpers

| function | description
| --------- | -----------
| set_env | contextmanager to set env vars
| unset_env | contextmanager to unset env vars
| no_env | contextmanager to unset a single env var
| no_cov | contextmanager to disable coverage in subprocesses

## ``pytest_shutil.cmdline``: Command-line helpers

| function | description
| --------- | -----------
| umask | contextmanager to set the umask
| chdir | contextmanager to change to a directory
| TempDir | contextmanager for a temporary directory
| PrettyFormatter | simple text formatter for drawing title, paragrahs, hrs.
| copy_files | copy all files from one directory to another
| getch | cross-platform read of a single character from the screen
| which | analoge of unix ``which``
| get_real_python_executable | find our system Python, useful when running under virtualenv

## ````: Running things in subprocesses

| function | description
| --------- | -----------
| run | run a command, with options for capturing output, checking return codes.
| run_as_main | run a function as if it was the system entry point
| run_module_as_main | run a module as if it was the system entry point
| run_in_subprocess | run a function in a subprocess
| run_with_coverage | run a command with coverage enabled
