AnyValid 1.0.0
Library that eases partial matching of objects.

Any Valid
=========

The AnyValid class is a wrapper class to be used with, for example,
`formencode.validators <http://www.formencode.org/en/latest/modules/validators.html#module-formencode.validators>`__,
that lets you partially specify what kind of objects it should match. To
see the usefulness of this, it might be easier to first have a look at
mock's ANY object (`from unittest.mock's
documentation <http://docs.python.org/3/library/unittest.mock.html#any>`__):

    Sometimes you may need to make assertions about some of the
    arguments in a call to mock, but either not care about some of the
    arguments or want to pull them individually out of call\_args and
    make more complex assertions on them.

    To ignore certain arguments you can pass in objects that compare
    equal to everything. Calls to assert\_called\_with() and
    assert\_called\_once\_with() will then succeed no matter what was
    passed in.

    .. code:: python

        >>
        >> mock = Mock(return_value=None)
        >> mock('foo', bar=object())
        >> mock.assert_called_once_with('foo', bar=ANY)

    ANY can also be used in comparisons with call lists like
    mock\_calls:

    .. code:: python

        >> 
        >> m = MagicMock(return_value=None) 
        >> m(1) 
        >> m(1, 2) 
        >> m(object()) 
        >> m.mock_calls == [call(1), call(1, 2), ANY] 
        True

Now, what if you would like to make certain assertions about an
argument, but perhaps don't know the exact value, or want to avoid
certain values (for example ``None``). This is where AnyValid might come
in handy. It provides a really simple way to leverage all the great work
that has been put into formencode's validators, so that your testing
code can make advanced assertions while being easy to read and maintain.

Examples
========

Simple argument matching:

.. code:: python

>>> 
>>> from mock import Mock 
>>> from any_valid import AnyValid, Int, String 
>>> 
>>> def check_call(foo, bar): 
...     try: 
...         mock = Mock(return_value=None) 
...         mock(foo, bar=bar) 
...         mock.assert_called_once_with(AnyValid(String(min_lenght=3)),  
...                                      bar=AnyValid(Int(min=2))) 
...     except AssertionError: 
...         return False 
...     return True 
...  
>>> check_call('fo', 1) 
False 
>>> check_call(8, 0) 
False 
>>> check_call('foo', 2) 
True

Matching a loosely defined dict argument:

.. code:: python

>>> from any_valid import AnyValid, Number, OneOf 
>>> valid_input = { ...     'core_temperature': AnyValid(Number(min=35, max=41.5)), 
...     'protocol': AnyValid(OneOf(['https', 'http'])), 
...     } 
>>> mock = Mock(return_value=None) 
>>> mock({'core_temperature': 36.8, 'protocol': 'https'}) 
>>> mock.assert_called_with(valid_input) 
>>>
