<h2>2012/10/07 Version 1.0.0<a class="headerlink" href="#version-1-0-0" title="Permalink to this headline">¶</a></h2>
|
|
<p>No changes since 1.0.0 beta 1. This version has feature parity with
|
|
<a class="reference external" href="http://docs.python.org/py3k/library/unittest.mock.html#module-unittest.mock">unittest.mock</a>
|
|
in Python 3.3.</p>

|
<p>Full list of changes since 0.8:</p>
|
|
<ul class="simple">
|
|
<li><cite>mocksignature</cite>, along with the <cite>mocksignature</cite> argument to <cite>patch</cite>, removed</li>
|
|
<li>Support for deleting attributes (accessing deleted attributes will raise an
|
|
<cite>AttributeError</cite>)</li>
|
|
<li>Added the <cite>mock_open</cite> helper function for mocking the builtin <cite>open</cite></li>
|
|
<li><cite>__class__</cite> is assignable, so a mock can pass an <cite>isinstance</cite> check without
|
|
requiring a spec</li>
|
|
<li>Addition of <cite>PropertyMock</cite>, for mocking properties</li>
|
|
<li><cite>MagicMocks</cite> made unorderable by default (in Python 3). The comparison
|
|
methods (other than equality and inequality) now return <cite>NotImplemented</cite></li>
|
|
<li>Propagate traceback info to support subclassing of <cite>_patch</cite> by other
|
|
libraries</li>
|
|
<li><cite>create_autospec</cite> works with attributes present in results of <cite>dir</cite> that
|
|
can’t be fetched from the object’s class. Contributed by Konstantine Rybnikov</li>
|
|
<li>Any exceptions in an iterable <cite>side_effect</cite> will be raised instead of
|
|
returned</li>
|
|
<li>In Python 3, <cite>create_autospec</cite> now supports keyword only arguments</li>
|
|
<li>Added <cite>patch.stopall</cite> method to stop all active patches created by <cite>start</cite></li>

|
|
<li>BUGFIX: calling <cite>reset_mock</cite> on a <cite>MagicMock</cite> created with autospec could
|

|
|
<li>BUGFIX: passing multiple spec arguments to patchers (<cite>spec</cite> , <cite>spec_set</cite> and
|
|
<cite>autospec</cite>) had unpredictable results, now it is an error</li>
|
|
<li>BUGFIX: using <cite>spec=True</cite> <em>and</em> <cite>create=True</cite> as arguments to patchers could
|
|
result in using <cite>DEFAULT</cite> as the spec. Now it is an error instead</li>
|
|
<li>BUGFIX: using <cite>spec</cite> or <cite>autospec</cite> arguments to patchers, along with
|
|
<cite>spec_set=True</cite> did not work correctly</li>
|
|
<li>BUGFIX: using an object that evaluates to False as a spec could be ignored</li>
|
|
<li>BUGFIX: a list as the <cite>spec</cite> argument to a patcher would always result in a
|
|
non-callable mock. Now if <cite>__call__</cite> is in the spec the mock is callable</li>

instead of a <a class="reference internal" href="mock.html#mock.Mock" title="mock.Mock"><tt class="xref py py-class docutils literal"><span class="pre">Mock</span></tt></a> by default</li>
|
|
<li>The patchers (<cite>patch</cite>, <cite>patch.object</cite> and <cite>patch.dict</cite>), plus <cite>Mock</cite> and
|
|
<cite>MagicMock</cite>, take arbitrary keyword arguments for configuration</li>
|

to return the next value from the iterable</li>
|

<li>New <cite>new_callable</cite> argument to <cite>patch</cite> and <cite>patch.object</cite> allowing you to

|
<li>Protocol methods on <a class="reference internal" href="magicmock.html#mock.MagicMock" title="mock.MagicMock"><tt class="xref py py-class docutils literal"><span class="pre">MagicMock</span></tt></a> are magic mocks, and are created
|

|
|
a <cite>MagicMock</cite> instead of a <cite>Mock</cite> as it was previously</li>
|
|
<li>Addition of <a class="reference internal" href="mock.html#mock.Mock.attach_mock" title="mock.Mock.attach_mock"><tt class="xref py py-meth docutils literal"><span class="pre">attach_mock()</span></tt></a> method</li>

|
|
<li><cite>patch</cite> lookup is done at use time not at decoration time</li>
|
|
<li>In Python 2.6 or more recent, <cite>dir</cite> 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.</li>
|
|
<li>Module level <a class="reference internal" href="helpers.html#mock.FILTER_DIR" title="mock.FILTER_DIR"><tt class="xref py py-data docutils literal"><span class="pre">FILTER_DIR</span></tt></a> added to control whether <cite>dir(mock)</cite> filters
|
|
private attributes. <cite>True</cite> by default.</li>
|
|
<li><cite>patch.TEST_PREFIX</cite> for controlling how patchers recognise test methods when
|
|
used to decorate a class</li>
|
|
<li>Support for using Java exceptions as a <a class="reference internal" href="mock.html#mock.Mock.side_effect" title="mock.Mock.side_effect"><tt class="xref py py-attr docutils literal"><span class="pre">side_effect</span></tt></a> on Jython</li>
|
|
<li><cite>Mock</cite> call lists (<cite>call_args_list</cite>, <cite>method_calls</cite> & <cite>mock_calls</cite>) are now
|
|
custom list objects that allow membership tests for “sub lists” and have
|
|
a nicer representation if you <cite>str</cite> or <cite>print</cite> them</li>
|
|
<li>Mocks attached as attributes or return values to other mocks have calls
|
|
recorded in <cite>method_calls</cite> and <cite>mock_calls</cite> of the parent (unless a name is
|
|
already set on the child)</li>
|
|
<li>Improved failure messages for <cite>assert_called_with</cite> and
|
|
<cite>assert_called_once_with</cite></li>
|
|
<li>The return value of the <a class="reference internal" href="magicmock.html#mock.MagicMock" title="mock.MagicMock"><tt class="xref py py-class docutils literal"><span class="pre">MagicMock</span></tt></a> <cite>__iter__</cite> method can be set to
|
|
any iterable and isn’t required to be an iterator</li>
|
|
<li>Added the Mock API (<cite>assert_called_with</cite> etc) to functions created by
|
|
<tt class="xref py py-func docutils literal"><span class="pre">mocksignature()</span></tt></li>
|
|
<li>Tuples as well as lists can be used to specify allowed methods for <cite>spec</cite> &
|
|
<cite>spec_set</cite> arguments</li>
|
|
<li>Calling <cite>stop</cite> on an unstarted patcher fails with a more meaningful error
|
|
message</li>
|
|
<li>Renamed the internal classes <cite>Sentinel</cite> and <cite>SentinelObject</cite> to prevent abuse</li>
|
|
<li>BUGFIX: an error creating a patch, with nested patch decorators, won’t leave
|
|
patches in place</li>
|
|
<li>BUGFIX: <cite>__truediv__</cite> and <cite>__rtruediv__</cite> not available as magic methods on
|
|
mocks in Python 3</li>
|
|
<li>BUGFIX: <cite>assert_called_with</cite> / <cite>assert_called_once_with</cite> can be used with
|
|
<cite>self</cite> as a keyword argument</li>
|
|
<li>BUGFIX: when patching a class with an explicit spec / spec_set (not a
|
|
boolean) it applies “spec inheritance” to the return value of the created
|
|
mock (the “instance”)</li>
|
|
<li>BUGFIX: remove the <cite>__unittest</cite> marker causing traceback truncation</li>
|
|
<li>Removal of deprecated <cite>patch_object</cite></li>
|
|
<li>Private attributes <cite>_name</cite>, <cite>_methods</cite>, ‘_children’, <cite>_wraps</cite> and <cite>_parent</cite>
|
|
(etc) renamed to reduce likelihood of clash with user attributes.</li>
|
|
<li>Added license file to the distribution</li>

|
|
<p>mock 0.8.0 is the last version that will support Python 2.4.</p>
|
|
<ul>
|
|
<li><p class="first">The patchers (<cite>patch</cite>, <cite>patch.object</cite> and <cite>patch.dict</cite>), plus <cite>Mock</cite> and
|
|
<cite>MagicMock</cite>, take arbitrary keyword arguments for configuration</p>
|
|
</li>
|
|
<li><p class="first">New mock method <cite>configure_mock</cite> for setting attributes and return values /
|
|
side effects on the mock and its attributes</p>
|
|
</li>
|
|
<li><p class="first">In Python 2.6 or more recent, <cite>dir</cite> 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.</p>
|
|
</li>
|
|
<li><p class="first">Module level <cite>FILTER_DIR</cite> added to control whether <cite>dir(mock)</cite> filters
|
|
private attributes. <cite>True</cite> by default. Note that <cite>vars(Mock())</cite> can still be
|
|
used to get all instance attributes and <cite>dir(type(Mock())</cite> will still return
|
|
all the other attributes (irrespective of <cite>FILTER_DIR</cite>)</p>
|
|
</li>
|
|
<li><p class="first"><cite>patch</cite> and <cite>patch.object</cite> now create a <cite>MagicMock</cite> instead of a <cite>Mock</cite> by
|
|
default</p>
|
|
</li>
|
|
<li><p class="first">Added <cite>ANY</cite> for ignoring arguments in <cite>assert_called_with</cite> calls</p>
|
|
</li>
|
|
<li><p class="first">Addition of <cite>call</cite> helper object</p>
|
|
</li>
|
|
<li><p class="first">Protocol methods on <cite>MagicMock</cite> are magic mocks, and are created lazily on
|
|
first lookup. This means the result of calling a protocol method is a
|
|
MagicMock instead of a Mock as it was previously</p>
|
|
</li>
|
|
<li><p class="first">Added the Mock API (<cite>assert_called_with</cite> etc) to functions created by
|
|
<cite>mocksignature</cite></p>
|
|
</li>
|
|
<li><p class="first">Private attributes <cite>_name</cite>, <cite>_methods</cite>, ‘_children’, <cite>_wraps</cite> and <cite>_parent</cite>
|
|
(etc) renamed to reduce likelihood of clash with user attributes.</p>
|
|
</li>
|
|
<li><p class="first">Implemented auto-speccing (recursive, lazy speccing of mocks with mocked
|
|
signatures for functions/methods)</p>
|
|
<p>Limitations:</p>
|
|
<ul class="simple">
|
|
<li>Doesn’t mock magic methods or attributes (it creates MagicMocks, so the
|
|
magic methods are <em>there</em>, they just don’t have the signature mocked nor
|
|
are attributes followed)</li>
|
|
<li>Doesn’t mock function / method attributes</li>
|
|
<li>Uses object traversal on the objects being mocked to determine types - so
|
|
properties etc may be triggered</li>
|
|
<li>The return value of mocked classes (the ‘instance’) has the same call
|
|
signature as the class __init__ (as they share the same spec)</li>
|
|
</ul>
|
|
<p>You create auto-specced mocks by passing <cite>autospec=True</cite> to <cite>patch</cite>.</p>
|
|
<p>Note that attributes that are None are special cased and mocked without a
|
|
spec (so any attribute / method can be used). 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.</p>
|
|
<p>Note that the <cite>autospec</cite> option to <cite>patch</cite> obsoletes the <cite>mocksignature</cite>
|
|
option.</p>
|
|
</li>
|
|
<li><p class="first">Added the <cite>create_autospec</cite> function for manually creating ‘auto-specced’
|
|
mocks</p>
|
|
</li>
|
|
<li><p class="first">Removal of deprecated <cite>patch_object</cite></p>

<li>A new ‘create’ keyword argument to patch and patch_object that allows them to patch

your own risk!)</li>

<li>The methods keyword argument to Mock has been removed and merged with spec. The spec

<li>Nested patches may now be applied in a different order (created mocks passed

in the opposite order). This is actually a bugfix.</li>
|
|
<li>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

value for the mock will also use the class as a spec.</li>

|
|
<p><cite>wraps</cite> is not integrated with magic methods.</p>
|
|
<p><cite>patch</cite> 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.</p>
|
|
<p><cite>Mock</cite> 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 <em>hide</em> these attributes when needed. In 0.8 many, but not all, of these
|
|
attributes are renamed to gain a <cite>_mock</cite> prefix, making it less likely that
|
|
they will clash. Any outstanding attributes that haven’t been modified with
|
|
the prefix should be changed.</p>
|
|
<p>If a patch is started using <cite>patch.start</cite> 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.</p>
|
|
<p>When a <cite>Mock</cite> is created by <cite>patch</cite>, arbitrary keywords can be used to set
|
|
attributes. If <cite>patch</cite> is created with a <cite>spec</cite>, and is replacing a class, then
|
|
a <cite>return_value</cite> mock is created. The keyword arguments are not applied to the
|
|
child mock, but could be.</p>
|
|
<p>When mocking a class with <cite>patch</cite>, passing in <cite>spec=True</cite> or <cite>autospec=True</cite>,
|
|
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 (<cite>inherit</cite>) to the Mock constructor? <cite>create_autospec</cite> does this, so
|
|
an additional keyword argument to Mock is probably unnecessary.</p>
|
|
<p>The <cite>mocksignature</cite> argument to <cite>patch</cite> with a non <cite>Mock</cite> passed into
|
|
<cite>new_callable</cite> will <em>probably</em> cause an error. Should it just be invalid?</p>
|
|
<p>Note that <cite>NonCallableMock</cite> and <cite>NonCallableMagicMock</cite> still have the unused
|
|
(and unusable) attributes: <cite>return_value</cite>, <cite>side_effect</cite>, <cite>call_count</cite>,
|
|
<cite>call_args</cite> and <cite>call_args_list</cite>. These could be removed or raise errors on
|
|
getting / setting. They also have the <cite>assert_called_with</cite> and
|
|
<cite>assert_called_once_with</cite> methods. Removing these would be pointless as
|
|
fetching them would create a mock (attribute) that could be called without
|
|
error.</p>
|
|
<p>Some outstanding technical debt. The way autospeccing mocks function
|
|
signatures was copied and modified from <cite>mocksignature</cite>. 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 <cite>patch.multiple</cite>
|
|
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.)</p>
|
|
<p>Passing arbitrary keyword arguments to <cite>create_autospec</cite>, or <cite>patch</cite> with
|
|
<cite>autospec</cite>, when mocking a <em>function</em> works fine. However, the arbitrary
|
|
attributes are set on the created mock - but <cite>create_autospec</cite> 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?</p>
|
|
<p><cite>mocksignature</cite>, plus the <cite>call_args_list</cite> and <cite>method_calls</cite> attributes of
|
|
<cite>Mock</cite> could all be deprecated.</p>
