1036 | + """ |
1037 | + Create a new `Mock` object. `Mock` takes several optional arguments |
1038 | + that specify the behaviour of the Mock object: |
1039 | + |
1040 | + * `spec`: This can be either a list of strings or an existing object (a |
1041 | + class or instance) that acts as the specification for the mock object. If |
1042 | + you pass in an object then a list of strings is formed by calling dir on |
1043 | + the object (excluding unsupported magic attributes and methods). Accessing |
1044 | + any attribute not in this list will raise an `AttributeError`. |
1045 | + |
1046 | + If `spec` is an object (rather than a list of strings) then |
1047 | + `mock.__class__` returns the class of the spec object. This allows mocks |
1048 | + to pass `isinstance` tests. |
1049 | + |
1050 | + * `spec_set`: A stricter variant of `spec`. If used, attempting to *set* |
1051 | + or get an attribute on the mock that isn't on the object passed as |
1052 | + `spec_set` will raise an `AttributeError`. |
1053 | + |
1054 | + * `side_effect`: A function to be called whenever the Mock is called. See |
1055 | + the `side_effect` attribute. Useful for raising exceptions or |
1056 | + dynamically changing return values. The function is called with the same |
1057 | + arguments as the mock, and unless it returns `DEFAULT`, the return |
1058 | + value of this function is used as the return value. |
1059 | + |
1060 | + Alternatively `side_effect` can be an exception class or instance. In |
1061 | + this case the exception will be raised when the mock is called. |
1062 | + |
1063 | + If `side_effect` is an iterable then each call to the mock will return |
1064 | + the next value from the iterable. If any of the members of the iterable |
1065 | + are exceptions they will be raised instead of returned. |
1066 | + |
1067 | + * `return_value`: The value returned when the mock is called. By default |
1068 | + this is a new Mock (created on first access). See the |
1069 | + `return_value` attribute. |
1070 | + |
1071 | + * `wraps`: Item for the mock object to wrap. If `wraps` is not None then |
1072 | + calling the Mock will pass the call through to the wrapped object |
1073 | + (returning the real result). Attribute access on the mock will return a |
1074 | + Mock object that wraps the corresponding attribute of the wrapped object |
1075 | + (so attempting to access an attribute that doesn't exist will raise an |
1076 | + `AttributeError`). |
1077 | + |
1078 | + If the mock has an explicit `return_value` set then calls are not passed |
1079 | + to the wrapped object and the `return_value` is returned instead. |
1080 | + |
1081 | + * `name`: If the mock has a name then it will be used in the repr of the |
1082 | + mock. This can be useful for debugging. The name is propagated to child |
1083 | + mocks. |
1084 | + |
1085 | + Mocks can also be called with arbitrary keyword arguments. These will be |
1086 | + used to set attributes on the mock after it is created. |

1503 | + """ |
1504 | + `patch` acts as a function decorator, class decorator or a context |
1505 | + manager. Inside the body of the function or with statement, the `target` |
1506 | + is patched with a `new` object. When the function/with statement exits |
1507 | + the patch is undone. |
1508 | + |
1509 | + If `new` is omitted, then the target is replaced with a |
1510 | + `MagicMock`. If `patch` is used as a decorator and `new` is |
1511 | + omitted, the created mock is passed in as an extra argument to the |
1512 | + decorated function. If `patch` is used as a context manager the created |
1513 | + mock is returned by the context manager. |
1514 | + |
1515 | + `target` should be a string in the form `'package.module.ClassName'`. The |
1516 | + `target` is imported and the specified object replaced with the `new` |
1517 | + object, so the `target` must be importable from the environment you are |
1518 | + calling `patch` from. The target is imported when the decorated function |
1519 | + is executed, not at decoration time. |
1520 | + |
1521 | + The `spec` and `spec_set` keyword arguments are passed to the `MagicMock` |
1522 | + if patch is creating one for you. |
1523 | + |
1524 | + In addition you can pass `spec=True` or `spec_set=True`, which causes |
1525 | + patch to pass in the object being mocked as the spec/spec_set object. |
1526 | + |
1527 | + `new_callable` allows you to specify a different class, or callable object, |
1528 | + that will be called to create the `new` object. By default `MagicMock` is |
1529 | + used. |
1530 | + |
1531 | + A more powerful form of `spec` is `autospec`. If you set `autospec=True` |
1532 | + then the mock with be created with a spec from the object being replaced. |
1533 | + All attributes of the mock will also have the spec of the corresponding |
1534 | + attribute of the object being replaced. Methods and functions being |
1535 | + mocked will have their arguments checked and will raise a `TypeError` if |
1536 | + they are called with the wrong signature. For mocks replacing a class, |
1537 | + their return value (the 'instance') will have the same spec as the class. |
1538 | + |
1539 | + Instead of `autospec=True` you can pass `autospec=some_object` to use an |
1540 | + arbitrary object as the spec instead of the one being replaced. |
1541 | + |
1542 | + By default `patch` will fail to replace attributes that don't exist. If |
1543 | + you pass in `create=True`, and the attribute doesn't exist, patch will |
1544 | + create the attribute for you when the patched function is called, and |
1545 | + delete it again afterwards. This is useful for writing tests against |
1546 | + attributes that your production code creates at runtime. It is off by by |
1547 | + default because it can be dangerous. With it switched on you can write |
1548 | + passing tests against APIs that don't actually exist! |
1549 | + |
1550 | + Patch can be used as a `TestCase` class decorator. It works by |
1551 | + decorating each test method in the class. This reduces the boilerplate |
1552 | + code when your test methods share a common patchings set. `patch` finds |
1553 | + tests by looking for method names that start with `patch.TEST_PREFIX`. |
1554 | + By default this is `test`, which matches the way `unittest` finds tests. |
1555 | + You can specify an alternative prefix by setting `patch.TEST_PREFIX`. |
1556 | + |
1557 | + Patch can be used as a context manager, with the with statement. Here the |
1558 | + patching applies to the indented block after the with statement. If you |
1559 | + use "as" then the patched object will be bound to the name after the |
1560 | + "as"; very useful if `patch` is creating a mock object for you. |
1561 | + |
1562 | + `patch` takes arbitrary keyword arguments. These will be passed to |
1563 | + the `Mock` (or `new_callable`) on construction. |
1564 | + |
1565 | + `patch.dict(...)`, `patch.multiple(...)` and `patch.object(...)` are |
1566 | + available for alternate use-cases. |
