* [3.9] bpo-37116: Use PEP 570 syntax for positional-only parameters. (GH-12620)Serhiy Storchaka2019-06-052-21/+3

* bpo-32972: Async test case (GH-13386)Andrew Svetlov2019-05-294-5/+371
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add explicit `asyncSetUp` and `asyncTearDown` methods. The rest is the same as for #13228 `AsyncTestCase` create a loop instance for every test for the sake of test isolation. Sometimes a loop shared between all tests can speed up tests execution time a lot but it requires control of closed resources after every test finish. Basically, it requires nested supervisors support that was discussed with @1st1 many times. Sorry, asyncio supervisors have no chance to land on Python 3.8. The PR intentionally does not provide API for changing the used event loop or getting the test loop: use `asyncio.set_event_loop_policy()` and `asyncio.get_event_loop()` instead. The PR adds four overridable methods to base `unittest.TestCase` class: ``` def _callSetUp(self): self.setUp() def _callTestMethod(self, method): method() def _callTearDown(self): self.tearDown() def _callCleanup(self, function, /, *args, **kwargs): function(*args, **kwargs) ``` It allows using asyncio facilities with minimal influence on the unittest code. The last but not least: the PR respects contextvars. The context variable installed by `asyncSetUp` is available on test, `tearDown` and a coroutine scheduled by `addCleanup`. https://bugs.python.org/issue32972

* Mock 100% coverage (GH-13045)Chris Withers2019-05-019-317/+263
| | | | | | | | | | | This was achieved by: * moving many pass statements in tests onto their own lines, so they pass line coverage and can match an easy ignore pattern if branch coverage is added later. * removing code that cannot be reached. * removing long-disabled tests. * removing unused code. * adding tests for uncovered code It turned out that removing `if __name__ == '__main__'` blocks that run unittest.main() at the bottom of test files was surprisingly contentious, so they remain and can be filtered out with an appropriate .coveragerc.
* remove jython support from unittest.mock (GH#13033)Chris Withers2019-05-013-25/+2

* Don't report deleted attributes in __dir__ (GH#10148)Mario Corchero2019-04-302-2/+13
| | | | | | When an attribute is deleted from a Mock, a sentinel is added rather than just deleting the attribute. This commit checks for such sentinels when returning the child mocks in the __dir__ method as users won't expect deleted attributes to appear when performing dir(mock).

* bpo-36593: Fix isinstance check for Mock objects with spec executed under ↵Xtreak2019-04-132-1/+39
| | | | | tracing (GH-12790) In Python having a trace function in effect while mock is imported causes isinstance to be wrong for MagicMocks. This is due to the usage of super() in some class methods, as this sets the __class__ attribute. To avoid this, as a workaround, alias the usage of super .
* bpo-36492: Deprecate passing some arguments as keyword arguments. (GH-12637)Serhiy Storchaka2019-04-012-3/+101
| | | | | | | | | | | | | | | | | | | | | | Deprecated passing the following arguments as keyword arguments: - "func" in functools.partialmethod(), weakref.finalize(), profile.Profile.runcall(), cProfile.Profile.runcall(), bdb.Bdb.runcall(), trace.Trace.runfunc() and curses.wrapper(). - "function" in unittest.addModuleCleanup() and unittest.TestCase.addCleanup(). - "fn" in the submit() method of concurrent.futures.ThreadPoolExecutor and concurrent.futures.ProcessPoolExecutor. - "callback" in contextlib.ExitStack.callback(), contextlib.AsyncExitStack.callback() and contextlib.AsyncExitStack.push_async_callback(). - "c" and "typeid" in the create() method of multiprocessing.managers.Server and multiprocessing.managers.SharedMemoryServer. - "obj" in weakref.finalize(). Also allowed to pass arbitrary keyword arguments (even "self" and "func") if the above arguments are passed as positional argument.
* bpo-36366: Return None on stopping unstarted patch object (GH-12472)Xtreak2019-03-282-3/+11

* bpo-35513, unittest: TextTestRunner uses time.perf_counter() (GH-11180)Victor Stinner2018-12-171-2/+2
| | | | | | | TextTestRunner of unittest.runner now uses time.perf_counter() rather than time.time() to measure the execution time of a test: time.time() can go backwards, whereas time.perf_counter() is monotonic. Similar change made in libregrtest, pprint and random.

| | | | | | | | | | | | | | | | | | | | | | | * tests: Further validate `wraps` functionality in `unittest.mock.Mock` Add more tests to validate how `wraps` interacts with other features of mocks. * Don't call the wrapped object if `side_effect` is set When a object is wrapped using `Mock(wraps=...)`, if an user sets a `side_effect` in one of their methods, return the value of `side_effect` and don't call the original object. * Refactor what to be called on `mock_call` When a `Mock` is called, it should return looking up in the following order: `side_effect`, `return_value`, `wraps`. If any of the first two return `mock.DEFAULT`, lookup in the next option. It makes no sense to check for `wraps` returning default, as it is supposed to be the original implementation and there is nothing to fallback to.
