# inside the test under Python 3.3. That may be due to a
|
|
# difference in the import implementation not triggering
|
|
# warnings properly when the module is reloaded, or
|
|
# because the warnings module is mostly implemented in C
|
|
# and something isn't cleanly resetting the global state
|
|
# used to track whether a warning needs to be
|
|
# emitted. Whatever the cause, we definitely see the
|
|
# warnings.warn() being invoked on a reload (see the test
|
|
# above) and warnings are reported on the console when we
|
|
# run the tests. A simpler test script run outside of
|
|
# testr does correctly report the warnings.
