`__unittest` marker causing traceback truncation + + +2011/06/14 Version 0.8.0 alpha 1 +-------------------------------- + +mock 0.8.0 is the last version that will support Python 2.4. + +* The patchers (`patch`, `patch.object` and `patch.dict`), plus `Mock` and + `MagicMock`, take arbitrary keyword arguments for configuration +* New mock method `configure_mock` for setting attributes and return values / + side effects on the mock and its attributes +* In Python 2.6 or more recent, `dir` on a mock will report all the dynamically + created attributes (or the full list of attributes if there is a spec) as + well as all the mock methods and attributes. +* Module level `FILTER_DIR` added to control whether `dir(mock)` filters + private attributes. `True` by default.

This is because None is + typically used as a default value for attributes that may be of some other + type, and as we don't know what type that may be we allow all access. + + Note that the `autospec` option to `patch` obsoletes the `mocksignature` + option. + +* Added the `create_autospec` function for manually creating 'auto-specced' + mocks +* Removal of deprecated `patch_object` + + +2011/05/30 Version 0.7.2 +------------------------ + +* BUGFIX: instances of list subclasses can now be used as mock specs +* BUGFIX: MagicMock equality / inequality protocol methods changed to use the + default equality / inequality.

(Potentially unsafe to use - it can allow + you to have tests that pass when they are testing an API that doesn't exist - use at + your own risk!) +* The methods keyword argument to Mock has been removed and merged with spec. The spec + argument can now be a list of methods or an object to take the spec from. +* Nested patches may now be applied in a different order (created mocks passed + in the opposite order). This is actually a bugfix. +* patch and patch_object now take a spec keyword argument. If spec is + passed in as 'True' then the Mock created will take the object it is replacing + as its spec object. If the object being replaced is a class, then the return + value for the mock will also use the class as a spec. +* A Mock created without a spec will not attempt to mock any magic methods / attributes + (they will raise an ``AttributeError`` instead). + + +2008/10/12 Version 0.4.0 +------------------------ + +* Default return value is now a new mock rather than None +* return_value added as a keyword argument to the constructor +* New method 'assert_called_with' +* Added 'side_effect' attribute / keyword argument called when mock is called +* patch decorator split into two decorators: + + - ``patch_object`` which takes an object and an attribute name to patch + (plus optionally a value to patch with which defaults to a mock object) + - ``patch`` which takes a string specifying a target to patch; in the form + 'package.module.Class.attribute'. (plus optionally a value to + patch with which defaults to a mock object) + +* Can now patch objects with ``None`` +* Change to patch for nose compatibility with error reporting in wrapped functions +* Reset no longer clears children / return value etc - it just resets + call count and call args. It also calls reset on all children (and + the return value if it is a mock). + +Thanks to Konrad Delong, Kevin Dangoor and others for patches and suggestions. + + +2007/12/03 Version 0.3.1 +------------------------- + +``patch`` maintains the name of decorated functions for compatibility with nose +test autodiscovery. + +Tests decorated with ``patch`` that use the two argument form (implicit mock +creation) will receive the mock(s) passed in as extra arguments. + +Thanks to Kevin Dangoor for these changes. + + +2007/11/30 Version 0.3.0 +------------------------- + +Removed ``patch_module``. ``patch`` can now take a string as the first +argument for patching modules. + +The third argument to ``patch`` is optional - a mock will be created by +default if it is not passed in. + + +2007/11/21 Version 0.2.1 +------------------------- + +Bug fix, allows reuse of functions decorated with ``patch`` and ``patch_module``. + + +2007/11/20 Version 0.2.0 +------------------------- + +Added ``spec`` keyword argument for creating ``Mock`` objects from a +specification object. + +Added ``patch`` and ``patch_module`` monkey patching decorators. + +Added ``sentinel`` for convenient access to unique objects. + +Distribution includes unit tests. + + +2007/11/19 Version 0.1.0 +------------------------- + +Initial release. + + +TODO and Limitations +==================== + +Contributions, bug reports and comments welcomed! + +Feature requests and bug reports are handled on the issue tracker: + + * `mock issue tracker <http://code.google.com/p/mock/issues/list>`_ + +`wraps` is not integrated with magic methods. + +`patch` could auto-do the patching in the constructor and unpatch in the +destructor. This would be useful in itself, but violates TOOWTDI and would be +unsafe for IronPython & PyPy (non-deterministic calling of destructors). +Destructors aren't called in CPython where there are cycles, but a weak +reference with a callback can be used to get round this. + +`Mock` has several attributes. This makes it unsuitable for mocking objects +that use these attribute names. A way round this would be to provide methods +that *hide* these attributes when needed. In 0.8 many, but not all, of these +attributes are renamed to gain a `_mock` prefix, making it less likely that +they will clash. Any outstanding attributes that haven't been modified with +the prefix should be changed. + +If a patch is started using `patch.start` and then not stopped correctly then +the unpatching is not done. Using weak references it would be possible to +detect and fix this when the patch object itself is garbage collected. This +would be tricky to get right though. + +When a `Mock` is created by `patch`, arbitrary keywords can be used to set +attributes. If `patch` is created with a `spec`, and is replacing a class, then +a `return_value` mock is created. The keyword arguments are not applied to the +child mock, but could be. + +When mocking a class with `patch`, passing in `spec=True` or `autospec=True`, +the mock class has an instance created from the same spec. Should this be the +default behaviour for mocks anyway (mock return values inheriting the spec +from their parent), or should it be controlled by an additional keyword +argument (`inherit`) to the Mock constructor? `create_autospec` does this, so +an additional keyword argument to Mock is probably unnecessary. + +The `mocksignature` argument to `patch` with a non `Mock` passed into +`new_callable` will *probably* cause an error. Should it just be invalid? + +Note that `NonCallableMock` and `NonCallableMagicMock` still have the unused +(and unusable) attributes: `return_value`, `side_effect`, `call_count`, +`call_args` and `call_args_list`. These could be removed or raise errors on +getting / setting. They also have the `assert_called_with` and +`assert_called_once_with` methods. Removing these would be pointless as +fetching them would create a mock (attribute) that could be called without +error. + +Some outstanding technical debt. The way autospeccing mocks function +signatures was copied and modified from `mocksignature`. This could all be +refactored into one set of functions instead of two. The way we tell if +patchers are started and if a patcher is being used for a `patch.multiple` +call are both horrible. There are now a host of helper functions that should +be rationalised. (Probably time to split mock into a package instead of a +module.) + +Passing arbitrary keyword arguments to `create_autospec`, or `patch` with +`autospec`, when mocking a *function* works fine. However, the arbitrary +attributes are set on the created mock - but `create_autospec` returns a +real function (which doesn't have those attributes). However, what is the use +case for using autospec to create functions with attributes that don't exist +on the original? + +`mocksignature`, plus the `call_args_list` and `method_calls` attributes of +`Mock` could all be deprecated. |
