tl;dr Equals is a stricter version of
`Mock.Any `__.

Equals allows you to assert certain equality constraints between python
objects during testing. There are times where we don't want to assert
absolute equality, e.g. we need to ensure two lists have the same
elements, but don't care about order. This was designed specifically for
usage with `Mock `_ and `dobles `_.

**Full Documentation is available at http://equals.readthedocs.org/en/latest/.**

Usage
=====

With Mock:
----------

::

from mock import Mock
from equals import any_dict

test_object = Mock()
test_object.method({'bob': 'barker'})
test_object.method.assert_called_with(any_dict)

dobles:
-------

::

from dobles import expect
from equals import any_string

class TestClass(object):
def method(self, arg):
return arg

test_object = TestClass()
expect(test_object).method.with_args(any_string.containing('bob'))

test_object.method('bob barker')

API
===

**NOTE: These are examples, each of these examples illustrates a way that equals could be used while writing unit tests.**

strings:
--------

::

from equals import any_string

any_string.containing('abc') == '123 abc 456'
any_string.starting_with('abc') == 'abcdef'
any_string.ending_with('abc') == '123abc'
any_string.matching('^abc$') == 'abc'

numbers:
--------

::

from equals import any_number

any_number.less_than(5) == 4
any_number.less_than_or_equal_to(5) == 5
any_number.greater_than(4) == 5
any_number.greater_than_or_equal_to(5) == 5
any_number.between(1, 3) == 2

dictionaries:
-------------

::

from equals import any_dict

any_dict.containing(1, 2) == {1: 2, 2:3, 4:5}
any_dict.containing(foo='bar') == {
'foo': 'bar',
'bob': 'barker'
}
any_dict.not_containing(1, foo=5) == {'foo':3, 4:5}

iterators:
----------

::

from equals import any_iterable

any_iterable.containing(1, 2, 3) == [1, 2, 3, 4, 5]
any_iterable.containing_only(1, 2, 3) == [2, 3, 1]
any_iterable.not_containing(1, 2) == [3, 4]
any_iterable.with_length(2) == [3, 4]

objects:
--------

::

from equals import anything

anything == None
anything == True
anything == {1: 1}
anything_true == 'dd'
anything_false == ''

instance_of(dict) == {}
anything.with_attrs(foo='bar', bob='barker') == Dummy('bar', 'barker')
instance_of(Dummy).with_attrs(foo='bar', bob='barker') == Dummy('bar', 'barker')

Installation:
=============

::

>> pip install equals
