safely patch object attributes, dicts and environment variables.
Usage
----------------
Use the `monkeypatch funcarg`_ to safely patch the environment
variables, object attributes or dictionaries. For example, if you want
to set the environment variable ``ENV1`` and patch the
``os.path.abspath`` function to return a particular value during a test
function execution you can write it down like this:
.. sourcecode:: python
def test_mytest(monkeypatch):
monkeypatch.setenv('ENV1', 'myval')
monkeypatch.setattr(os.path, 'abspath', lambda x: '/')
... # your test code
The function argument will do the modifications and memorize the
old state. After the test function finished execution all
modifications will be reverted. See the `monkeypatch blog post`_
for an extensive discussion.

pytest_oejskit plugin (EXTERNAL)
==========================================
The `oejskit`_ offers a py.test plugin for running Javascript tests in life browers. Running inside the browsers comes with some speed cost, on the other hand it means for example the code is tested against the real-word DOM implementations.
The approach enables to write integration tests such that the JavaScript code is tested against server-side Python code mocked as necessary. Any server-side framework that can already be exposed through WSGI (or for which a subset of WSGI can be written to accommodate the jskit own needs) can play along.
For more info and download please visit the `oejskit PyPI`_ page.

helpers for asserting deprecation and other warnings.
**recwarn**: function argument where one can call recwarn.pop() to get
the last warning that would have been shown.
.. contents::
:local:
Example usage
---------------------
You can use the ``recwarn`` funcarg to track
warnings within a test function:
.. sourcecode:: python
def test_hello(recwarn):
from warnings import warn
warn("hello", DeprecationWarning)
w = recwarn.pop(DeprecationWarning)
assert issubclass(w.category, DeprecationWarning)
assert 'hello' in str(w.message)
assert w.filename
assert w.lineno
You can also call a global helper for checking
taht a certain function call yields a Deprecation
warning:
.. sourcecode:: python
import py
def test_global():
py.test.deprecated_call(myfunction, 17)
**py.test.deprecated_call(func, *args, **kwargs)**: assert that the given function call triggers a deprecation warning.
.. _`recwarn funcarg`:

Getting and improving this plugin

Do you find the above documentation or the plugin itself lacking,
not fit for what you need? Here is a **30 seconds guide**
to get you started on improving the plugin:
Do you find the above documentation or the plugin itself lacking?
1. Download `pytest_terminal.py`_ plugin source code
2. put it somewhere as ``pytest_terminal.py`` into your import path
3. a subsequent test run will now use your local version!
3. a subsequent ``py.test`` run will use your local version
