cykooz.testing 1.2

Collection of helper utilities for testing.

cykooz.testing is collection of helper utilities for testing.

Utilities

Dict

A dict object that can be compared with other dict object without regard to keys that did not presents in the Dict instance.

>>> from cykooz.testing import Dict
>>> expected = Dict(a=1, b='foo')
>>> d1 = {'a': 1, 'b': 'foo', 'c': True}
>>> d1 == expected
True
>>> d1 != expected
False
>>> d2 = {'a': 1, 'c': True}
>>> d2 == expected
False
>>> d1 != d2
True
>>> Dict({'a': 1})
Dict({'a': 1})

Short alias:

>>> from cykooz.testing import D
>>> {'a': 1, 'b': 'foo'} == D({'a': 1})
True

List

A list object that can be compared with other list object without regard to extra items contains in the other list object.

>>> from cykooz.testing import List
>>> expected = List([1, 'foo'])
>>> l1 = [1, 'foo', True]
>>> l1 == expected
True
>>> l1 != expected
False
>>> l2 = [1, True]
>>> l2 == expected
False
>>> l2 != expected
True
>>> expected == [1]
False
>>> [{'a': 1}, {'b': 2}] == List([Dict(), Dict()])
True

Also supported comparing without regard of ordering of items.

>>> expected = List([True, 1], ignore_order=True)
>>> l1 = [1, 'foo', True]
>>> l1 == expected
True
>>> l1 != expected
False
>>> [{'a': 1}, {'b': 2}] == List([Dict(), Dict()], ignore_order=True)
Traceback (most recent call last):
...
TypeError: unhashable type: 'Dict'

Short alias:

>>> from cykooz.testing import L
>>> [1, 'foo', True] == L([1, 'foo'])
True

AnyValue

Instance of this class is equal to any other values.

>>> from cykooz.testing import AnyValue
>>> v = AnyValue()
>>> v == 1
True
>>> 1 == v
True
>>> v != 1
False
>>> v == {'a': 1, 'b': 'foo'}
True
>>> v == [1, 2, 3, 'b']
True
>>> v == AnyValue()
True
>>> v
<any value>
>>> {v: 1}
Traceback (most recent call last):
...
TypeError: unhashable type: 'AnyValue'
>>> [v, v, v] == [1, 2, 'foo']
True
>>> [v, v, 1] == [1, 2, 'foo']
False
>>> [v, v] == [1, 2, 'foo']
False
>>> {'a': v, 'b': 2} == {'a': 1, 'b': 2}
True

Short alias:

>>> from cykooz.testing import ANY
>>> 1 == ANY
True

RegExpString

Instance of this class is equal to any other values if it is matched to give regexp pattern.

>>> from cykooz.testing import RegExpString
>>> v = RegExpString('first.*')
>>> v == 1
False
>>> 1 == v
False
>>> v != 1
True
>>> v == 'first class'
True
>>> 'first class' == v
True
>>> v != 'first class'
False
>>> v
<RegExpString: first.*>
>>> {v: 1}
Traceback (most recent call last):
...
TypeError: unhashable type: 'RegExpString'
>>> [v, v, v] == [1, 2, 'first class']
False
>>> [v, v, v] == ['first class', 'first bus', 'first time']
True

Short alias:

>>> from cykooz.testing import R
>>> 'first class' == R('first.*')
True

Url

A url object that can be compared with other url objects without regard to the vagaries of encoding, escaping, and ordering of parameters in query strings.

>>> from cykooz.testing import Url
>>> url1 = Url('https://domain.com/container?limit=6&offset=0')
>>> url2 = Url('https://domain.com/container?offset=0&limit=6')
>>> url1 == url2
True
>>> url2 = Url('https://domain.com/container?limit=6')
>>> url1 == url2
False
>>> url1 == 'https://domain.com/container?offset=0&limit=6'
True
>>> 'https://domain.com/container?offset=0&limit=6' == url1
True
>>> {'key': 'https://domain.com/container?offset=0&limit=6'} == {'key': url1}
True

Json

An instance of this class will be equal to any ‘bytes’ or ‘str’ value if object decoded by JSON-decoder from this value is equal to the first argument of this class.

>>> from cykooz.testing import Json
>>> v = Json({'foo': 1, 'bar': 'hello'})
>>> other = '{"bar": "hello", "foo": 1}'
>>> v == other
True
>>> other == v
True
>>> other != v
False
>>> v == 1
False
>>> 1 == v
False
>>> v != 1
True
>>> v == 'not json'
False
>>> 'not json' == v
False
>>> v != 'not json'
True
>>> v
<Json: {'foo': 1, 'bar': 'hello'}>
>>> {v: 1}
Traceback (most recent call last):
...
TypeError: unhashable type: 'Json'
>>> [v, v, v] == [other, 2, 'first class']
False
>>> [v, v, v] == [other, other, other]
True
>>> '"json str"' == Json('json str')
True

Complex example

>>> from cykooz.testing import D, L, R, J, Url, ANY
>>> some_value = {
...     'created': '2020-04-14T12:34:00.002000+00:00',
...     'is_active': True,
...     'items': [
...         {'key': 'a', 'value': 1},
...         {'key': 'b', 'value': 2},
...         {'key': 'c', 'value': 3},
...     ],
...     'source': 'https://domain.com/item?p=0&t=total',
...     'response': '{"status": 200, "body": "OK"}',
...     'size': 1024,
... }
>>> some_value == D({
...     'created': R('^2020-04.*'),
...     'is_active': True,
...     'items': L([
...         {'key': 'a', 'value': 1},
...         D({'value': ANY}),
...     ]),
...     'source': Url('https://domain.com/item?t=total&p=0'),
...     'response': J({'status': 200, 'body': ANY}),
... })
True
