Description
Feature or enhancement
Proposal:
The unittest.subTest context (i.e. the object you get using with's as clause, currently None) should get methods to manage cleanups:
addCleanupenterContextdoCleanups
And similar ones for IsolatedAsyncIOTestCase.
They should do the same thing as the same methods on TestCase, but with subtest scope.
Example usage:
for param in 'a', 'b', 'c':
with self.subTest() as sub:
tempfile = make_tempfile()
sub.addCleanup(os.unlink, tempfile)
do_actual_test(tempfile, param)See Discuss thread for motivation/discussion.
Has this already been discussed elsewhere?
