Agreed that the source is not at fault - it is the test environment that is at fault. However, it means that the test does not exercise all the library code - it might fail to pick up genuine faults - so I think that should be regarded as a test failure. The failure message should make it clear that the problem lies in the environment. > > -Rahul > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
