Bump mock from 4.0.3 to 5.1.0 in /platform

[dependabot]

Bumps mock from 4.0.3 to 5.1.0.

Changelog

Sourced from mock's changelog.

5.1.0

• bpo-44185: :func:unittest.mock.mock_open will call the :func:close method of the file handle mock when it is exiting from the context manager. Patch by Samet Yaslan.

• gh-94924: :func:unittest.mock.create_autospec now properly returns coroutine functions compatible with :func:inspect.iscoroutinefunction

• bpo-17013: Add ThreadingMock to :mod:unittest.mock that can be used to create Mock objects that can wait until they are called. Patch by Karthikeyan Singaravelan and Mario Corchero.

• bpo-41768: :mod:unittest.mock speccing no longer calls class properties. Patch by Melanie Witt.

5.0.2

• gh-102978: Fixes :func:unittest.mock.patch not enforcing function signatures for methods decorated with @classmethod or @staticmethod when patch is called with autospec=True.

• gh-103329: Regression tests for the behaviour of unittest.mock.PropertyMock were added.

5.0.1

• gh-100740: Fix unittest.mock.Mock not respecting the spec for attribute names prefixed with assert.

• gh-100690: Mock objects which are not unsafe will now raise an AttributeError when accessing an attribute that matches the name of an assertion but without the prefix assert_, e.g. accessing called_once instead of assert_called_once. This is in addition to this already happening for accessing attributes with prefixes assert, assret, asert, aseert, and assrt.

• gh-96127: inspect.signature was raising TypeError on call with mock objects. Now it correctly returns (*args, **kwargs) as infered signature.

5.0.0

• gh-98624: Add a mutex to unittest.mock.NonCallableMock to protect concurrent access to mock attributes.
