[New-bugs-announce] [issue44185] mock_open file handle __exit__ does not call close

[William Sjoblom]

New submission from William Sjoblom <wllmsjblm at gmail.com>:

A common testing scenario is assuring that opened files are closed. Since unittest.mock.mock_open() can be used as a context manager, it would be reasonable to expect its __exit__ to invoke close so that one can easily assert that the file was closed, regardless of if the file was opened with a plain call to open or with a context manager.
