Re: [Quickfixj-users] Push a Message log thru the engine to observe the behavior?

Hi,

there is no out-of-the-box solution but you could take a look at the tests in SessionTest.
https://github.com/quickfix-j/quickfixj/blob/master/quickfixj-core/src/test/java/quickfix/SessionTest.java

For example this one takes some messages, alters seqnums and checks the result:
https://github.com/quickfix-j/quickfixj/blob/1968f7abb981f486539a4cf3e4ae81fa5c554ec8/quickfixj-core/src/test/java/quickfix/SessionTest.java#L1962

All of the used methods in the Session class are public, so it is possible to copy that test more or 
less verbatim to your code base and test it with different versions by exchanging the quickfixj-core 
JAR file for example.
There also is a test for QFJ-673 here 
https://github.com/quickfix-j/quickfixj/blob/1968f7abb981f486539a4cf3e4ae81fa5c554ec8/quickfixj-core/src/test/java/quickfix/SessionTest.java#L1403
But I don't know if that is the exact problem that you are encountering.

Let me know how it went.

Cheers,
Chris.
