I have an abstract class NetworkTest and some derived classes PingTest, SMTPTest, and POP3Test. Each Test class overrides a Run() function and has it's own private member variables.

I have a txt file for each type of test - ping.txt, pop3.txt, smtp.txt that defines the tests that should be run, in the format

ping.txt

IP
IP
...

smtp.txt

server:port:usr:pw:email_address
server:port:usr:pw:email_address
...

pop3.txt

server:port
server:port
...

I have a ReadTestsFromFile() for each type of test. However, since these return a List(of TypeOfTest), they cannot be member functions of the derived classes. So the question is, where do I put ReadPingTestsFromFile(), ReadPop3TestsFromFile() and ReadSMTPTestsFromFile() ? I currently just have them in a module, but that seems a little less "principled" than the nice OOP structure I've been trying to follow with the rest of this program.

Can anyone comment on how you would do this?

Thanks!

Dave
