RE: [Quickfix-developers] Quickfix acceptance tests.

[Miller, O. <OM...@ri...>]

Tim,

Yes, you are correct, these holes do exist in the current test =
scenarios.  The good news it that the test runner does have the =
capability to test these scenarios.  We have an iDISCONNECT call which =
complements the iCONNECT call and will forcibly kill a tcp connection.  =
I think maybe the thing to do is to create additional versions of the =
8_*.def tests (the ones involving resend requests), and the 1_*.def =
tests (the ones involving logons).  These ones will test the same =
functionality by disconnecting and restablishing a logon instead of =
making the assumptions of the other tests.

Subject:	[Quickfix-developers] Quickfix acceptance tests.
The automated acceptance tests for quickfix are impressive but have some
very significant holes.

For example, the tests surrounding processing of resend requests do not
cover the most common resend scenario, namely loss of synchronization =
after
an unexpected loss of the TCP connection.   All the acceptance tests =
assume
that sequence numbers are set to 1 at every logon.  However, it is =
usually
at logon that the missing messages are detected.

One shouldn't, therefore, shouldn't get too complacent about the =
robustness
of the quickfix session level code, especially when it is talking to a =
buggy
peer fix app (e.g. one that often crashes), or over an unreliable =
network
connection.
