[issue15351] Add to unittest.TestCase support for using context managers

[Chris Jerdonek]

Chris Jerdonek <chris.jerdonek at gmail.com> added the comment:

Attached is a patch illustrating the API I suggested for discussion.

To add custom setup and teardown context managers, the user can override the following method:

    def executeTest(self):
        with self.setUpContext():
            self.runTestMethod()

The custom context managers can be placed either before or after the existing setUp/tearDown, or both.

The patch preserves the existing behavior that tearDown() should run only if setUp() was successful, and that doCleanups() should always run.  All tests continue to pass with the patch.
