Ok, you mean something like that:
Class ConnectionHandlerFactory
...
public IConnectonHandler getConnectonHandler()
{
if (test)
return new ConnectionHandlerTest();
else
return new ConnectionHandlerForTomcat();
}
but I think this has 2 problems:
1) in my production code I'll have code that is written just for testing
purpose
2) Before executing any test I have to set the "test" variable to true.
Or I did not understand?
