Python Fuzzy Matchers

Project description

Travis Test Status

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.

strings:

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:

any_number.less_than(5) == 4
any_number.less_than_or_equal(5) == 5
any_number.greater_than(4) == 5
any_number.greater_than_or_equal(5) == 5
any_number.between(1, 3) == 2

dictionaries:

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

iterators:

any_iter.containing(1, 2, 3) == [1, 2, 3, 4, 5]
any_iter.containing_only(1, 2, 3) == [2, 3, 1]

objects:

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')

Usage with Mock:

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

Usage with doubles:

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

test_object.method('bob barker')
