If patch() is used as a context manager the created Omitted, the created mock is passed in as an extra argument to theĭecorated function. If patch() is used as a decorator and new is If new is omitted, then the target is replaced with anĪsyncMock if the patched object is an async function or Inside the body of the function or with statement, the target Patch() acts as a function decorator, class decorator or a context

patch ( target, new = DEFAULT, spec = None, create = False, spec_set = None, autospec = None, new_callable = None, ** kwargs ) ¶ The key is to do the patching in the right namespace. All of these functions can also be used in with They automatically handle the unpatching for you,Įven if exceptions are raised. The patch decorators are used for patching objects only within the scope of Get a new Mock object when it expects a magic method. Will often implicitly request these methods, and gets very confused to Leading and trailing double underscores). The only exceptions are magic methods and attributes (those that have with patch ( '_main_.thing2', return_value = None ) as child2. > thing1 = object () > thing2 = object () > parent = MagicMock () > with patch ( '_main_.thing1', return_value = None ) as child1. Unsafe: By default, accessing any attribute with name starting withĪssert, assret, asert, aseert or assrt will raise anĪttributeError. This is a new Mock (created on first access). Return_value: The value returned when the mock is called. If side_effect is an iterable then each call to the mock will returnĪ side_effect can be cleared by setting it to None. This case the exception will be raised when the mock is called. Value of this function is used as the return value.Īlternatively side_effect can be an exception class or instance. The function is called with the sameĪrguments as the mock, and unless it returns DEFAULT, the return Useful for raising exceptions orĭynamically changing return values. Side_effect: A function to be called whenever the Mock is called. Or get an attribute on the mock that isn’t on the object passed as _class_ returns the class of the spec object. If spec is an object (rather than a list of strings) then The object (excluding unsupported magic attributes and methods).Īccessing any attribute not in this list will raise an AttributeError. You pass in an object then a list of strings is formed by calling dir on Spec: This can be either a list of strings or an existing object (aĬlass or instance) that acts as the specification for the mock object. That specify the behaviour of the Mock object: Mock ( spec = None, side_effect = None, return_value = DEFAULT, wraps = None, name = None, spec_set = None, unsafe = False, ** kwargs ) ¶Ĭreate a new Mock object. You can specify an alternative class of Mock using By default patch() will createĪ MagicMock for you.

In a particular module with a Mock object. The patch() decorators makes it easy to temporarily replace classes When you are mocking out objects that aren’t callable: There are also non-callable variants, useful MagicMock is a subclass of Mock with all the magic methods

Mocks record how you use them, allowing you to makeĪssertions about what your code has done to them. Mocks are callable and create attributes as Mock is a flexible mock object intended to replace the use of stubs and The _init_ method, and on callable objects where it copies the signature of TypeError: () takes exactly 3 arguments (1 given)Ĭreate_autospec() can also be used on classes, where it copies the signature of assert_called_once_with ( 1, 2, 3 ) > mock_function ( 'wrong arguments' ) Traceback (most recent call last). > mock_function = create_autospec ( function, return_value = 'fishy' ) > mock_function ( 1, 2, 3 ) 'fishy' > mock_function. > from unittest.mock import create_autospec > def function ( a, b, c ). YouĬan configure them, to specify return values or limit what attributes areĪvailable, and then make assertions about how they have been used: Methods as you access them and store details of how they have been used. Mock and MagicMock objects create all attributes and There is a backport of unittest.mock for earlier versions of Python, Is based on the ‘action -> assertion’ pattern instead of ‘record -> replay’ Mock is designed for use with unittest and

Unittest.mock provides a core Mock class removing the need toĬreate a host of stubs throughout your test suite. Replace parts of your system under test with mock objects and make assertions Unittest.mock is a library for testing in Python.
