Instead it should just skip the tests which need that particular asset. The only time aim to make it fatal is for 404 errors which are highly likely to reflect genuine problems to be fixed. We catch certain exception classes and handle them as transient errors, but unfortunately it is proving difficult to predict what exception classes urlopen() is capable of raising, with new possibilities being discovered. To provide a fail-safe, treat the generic Exception class as being a transient error too. This may well mask certain genuine bugs, but it is preferrable to prioritize running the test suite to the greatest extent practical. Signed-off-by: Daniel P.
