2009/08/22 Version 0.6.0
- New test layout compatible with test discovery
- Descriptors (static methods / class methods etc) can now be patched and
- Mocks can raise exceptions when called by setting side_effect to an
exception class or instance
- Mocks that wrap objects will not pass on calls to the underlying object if
an explicit return_value is set
2009/04/17 Version 0.5.0
- Made DEFAULT part of the public api.
- Documentation built with Sphinx.
- side_effect is now called with the same arguments as the mock is called with and
if returns a non-DEFAULT value that is automatically set as the mock.return_value.
- wraps keyword argument used for wrapping objects (and passing calls through to the wrapped object).
- Mock.reset renamed to Mock.reset_mock, as reset is a common API name.
- patch / patch_object are now context managers and can be used with with.
- A new ‘create’ keyword argument to patch and patch_object that allows them to patch
(and unpatch) attributes that don’t exist. (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
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.
