From: Lothar Scholz Date: 2004-04-12T06:20:32+09:00 Subject: Re: Testing a Protocol Class Hello Bill, I would suggest to use a separate class that abstracts from the transportation layer (TCP) and has a functional interface that corresponds 1:1 with the protocol commands. Testing the transportation layer is another test case and should include all the possible failure problems on a network. Mixing both testcases into a huge one makes testing much harder, and takes more lines of code to implement. -- Best regards, Lothar mailto:mailinglists@scriptolutions.com
