If you pass in an object then a list of strings is formed by calling dir on the object (excluding unsupported magic attributes and methods). Accessing any attribute not in this list will raise an `AttributeError`. If `spec` is an object (rather than a list of strings) then `mock.__class__` returns the class of the spec object. This allows mocks to pass `isinstance` tests. * `spec_set`: A stricter variant of `spec`. If used, attempting to *set* or get an attribute on the mock that isn't on the object passed as `spec_set` will raise an `AttributeError`. * `side_effect`: A function to be called whenever the Mock is called. See the `side_effect` attribute. Useful for raising exceptions or dynamically changing return values. The function is called with the same arguments as the mock, and unless it returns `DEFAULT`, the return value of this function is used as the return value. If `side_effect` is an iterable then each call to the mock will return the next value from the iterable. If any of the members of the iterable are exceptions they will be raised instead of returned. * `return_value`: The value returned when the mock is called. By default this is a new Mock (created on first access). See the `return_value` attribute. * `wraps`: Item for the mock object to wrap. If `wraps` is not None then calling the Mock will pass the call through to the wrapped object (returning the real result). Attribute access on the mock will return a Mock object that wraps the corresponding attribute of the wrapped object (so attempting to access an attribute that doesn't exist will raise an `AttributeError`). If the mock has an explicit `return_value` set then calls are not passed to the wrapped object and the `return_value` is returned instead. * `name`: If the mock has a name then it will be used in the repr of the mock. This can be useful for debugging. The name is propagated to child mocks. Mocks can also be called with arbitrary keyword arguments. These will be used to set attributes on the mock after it is created.

It takes the object to be patched (either as an object or a string to fetch the object by importing) and keyword arguments for the patches:: with patch.multiple(settings, FIRST_PATCH='one', SECOND_PATCH='two'): ... Use `DEFAULT` as the value if you want `patch.multiple` to create mocks for you. In this case the created mocks are passed into a decorated function by keyword, and a dictionary is returned when `patch.multiple` is used as a context manager. `patch.multiple` can be used as a decorator, class decorator or a context manager. The arguments `spec`, `spec_set`, `create`, `autospec` and `new_callable` have the same meaning as for `patch`. These arguments will be applied to *all* patches done by `patch.multiple`.

Inside the body of the function or with statement, the `target` is patched with a `new` object. When the function/with statement exits the patch is undone. If `new` is omitted, then the target is replaced with an `AsyncMock if the patched object is an async function or a `MagicMock` otherwise. If `patch` is used as a decorator and `new` is omitted, the created mock is passed in as an extra argument to the decorated function. If `patch` is used as a context manager the created mock is returned by the context manager. `target` should be a string in the form `'package.module.ClassName'`. The `target` is imported and the specified object replaced with the `new` object, so the `target` must be importable from the environment you are calling `patch` from. The target is imported when the decorated function is executed, not at decoration time. The `spec` and `spec_set` keyword arguments are passed to the `MagicMock` if patch is creating one for you. In addition you can pass `spec=True` or `spec_set=True`, which causes patch to pass in the object being mocked as the spec/spec_set object. `new_callable` allows you to specify a different class, or callable object, that will be called to create the `new` object. By default `AsyncMock` is used for async functions and `MagicMock` for the rest. A more powerful form of `spec` is `autospec`. If you set `autospec=True` then the mock will be created with a spec from the object being replaced. All attributes of the mock will also have the spec of the corresponding attribute of the object being replaced. Methods and functions being mocked will have their arguments checked and will raise a `TypeError` if they are called with the wrong signature. For mocks replacing a class, their return value (the 'instance') will have the same spec as the class. Instead of `autospec=True` you can pass `autospec=some_object` to use an arbitrary object as the spec instead of the one being replaced. By default `patch` will fail to replace attributes that don't exist. If you pass in `create=True`, and the attribute doesn't exist, patch will create the attribute for you when the patched function is called, and delete it again afterwards. This is useful for writing tests against attributes that your production code creates at runtime. It is off by default because it can be dangerous. With it switched on you can write passing tests against APIs that don't actually exist! Patch can be used as a `TestCase` class decorator. It works by decorating each test method in the class. This reduces the boilerplate code when your test methods share a common patchings set. `patch` finds tests by looking for method names that start with `patch.TEST_PREFIX`. By default this is `test`, which matches the way `unittest` finds tests. You can specify an alternative prefix by setting `patch.TEST_PREFIX`. Patch can be used as a context manager, with the with statement. Here the patching applies to the indented block after the with statement. If you use "as" then the patched object will be bound to the name after the "as"; very useful if `patch` is creating a mock object for you. Patch will raise a `RuntimeError` if passed some common misspellings of the arguments autospec and spec_set. Pass the argument `unsafe` with the value True to disable that check. `patch` takes arbitrary keyword arguments. These will be passed to `AsyncMock` if the patched object is asynchronous, to `MagicMock` otherwise or to `new_callable` if specified. `patch.dict(...)`, `patch.multiple(...)` and `patch.object(...)` are available for alternate use-cases. r )r r ) r r r r r r r r rP r r` r r r! r s K r c @ sj e Zd ZdZdddZdd Zdd Zd d Zd d Zdd Z dd Z dd Z dd Z dd Z dd ZdS ) _patch_dicta# Patch a dictionary, or dictionary like object, and restore the dictionary to its original state after the test. `in_dict` can be a dictionary or a mapping like container. If it is a mapping then it must at least support getting, setting and deleting items plus iterating over keys. `in_dict` can also be a string specifying the name of the dictionary, which will then be fetched by importing it. `values` can be a dictionary of values to set in the dictionary. `values` can also be an iterable of `(key, value)` pairs. If `clear` is True then the dictionary will be cleared before the new values are set. `patch.dict` can also be called with arbitrary keyword arguments to set values in the dictionary:: with patch.dict('sys.modules', mymodule=Mock(), other_module=Mock()): ... `patch.dict` can be used as a context manager, decorator or class decorator.

The :class:`AsyncMock` object will behave so the object is recognized as an async function, and the result of a call is an awaitable: >>> mock = AsyncMock() >>> iscoroutinefunction(mock) True >>> inspect.isawaitable(mock()) True The result of ``mock()`` is an async function which will have the outcome of ``side_effect`` or ``return_value``: - if ``side_effect`` is a function, the async function will return the result of that function, - if ``side_effect`` is an exception, the async function will raise the exception, - if ``side_effect`` is an iterable, the async function will return the next value of the iterable, however, if the sequence of result is exhausted, ``StopIteration`` is raised immediately, - if ``side_effect`` is not defined, the async function will return the value defined by ``return_value``, hence, by default, the async function returns a new :class:`AsyncMock` object. If the outcome of ``side_effect`` or ``return_value`` is an async function, the mock async function obtained when the mock object is called will be this async function itself (and not an async function returning an async function). The test author can also specify a wrapped object with ``wraps``. In this case, the :class:`Mock` object behavior is the same as with an :class:`.Mock` object: the wrapped object may have methods defined as async function functions.

Attributes on the mock will use the corresponding attribute on the `spec` object as their spec. Functions or methods being mocked will have their arguments checked to check that they are called with the correct signature. If `spec_set` is True then attempting to set attributes that don't exist on the spec object will raise an `AttributeError`. If a class is used as a spec then the return value of the mock (the instance of the class) will have the same spec. You can use a class as the spec for an instance object by passing `instance=True`. The returned mock will only be callable if instances of the mock are callable. `create_autospec` will raise a `RuntimeError` if passed some common misspellings of the arguments autospec and spec_set. Pass the argument `unsafe` with the value True to disable that check. `create_autospec` also takes arbitrary keyword arguments that are passed to the constructor of the created mock.z'Cannot autospec a Mock object.

It works for `open` called directly or used as a context manager. The `mock` argument is the mock object to configure. If `None` (the default) then a `MagicMock` will be created for you, with the API limited to methods or attributes available on standard file handles. `read_data` is a string for the `read`, `readline` and `readlines` of the file handle to return. This is an empty string by default.

Fetching a `PropertyMock` instance from an object calls the mock, with no args.

Given an input Mock, seals it to ensure no further mocks will be generated when accessing an attribute that was not already defined. The operation recursively seals the mock passed in, meaning that the mock itself, any mocks generated by accessing one of its attributes, and all assigned mocks without a name or spec will be sealed.
