[Quickfixj-users] Question about calculating time to send a Test Request message

[Toli K. <to...@ma...>]

Hey,

I also posted this as a JIRA question 236:
http://www.quickfixj.org/jira/browse/QFJ-236

We've been going through a certification process with TransactTools
(http://www.openfix.net/), and encountered a different expected
behaviour with sending Test Requests.

In the TransactTools test, they skip a heartbeat message and expect
our quickfix engine (Ie QFJ) to send a test request:
"We suppressed our last heartbeat message.
In response we expected to receive a test request message from you
within 9 seconds (30% of the HeartBeatInt field) but did not."

Seems like they expect it to be sent within HeartBeatInt+9secs.
Looking at the code in SessionState.isTestRequestNeeded(), it
calculates the Test Request delay as 1.5 * (HeartBeatInt +
numTestRequestsSent + 1), which translates into HeartBeatInt * 1.5
(for first request) = 30 + 15secs, which is over the +9 seconds that's
expected.

Is there a known spec for this formula or was it something
"reasonable" but not necessarily standard? Maybe it's something we
need to make configurable to satisfy different expectations form
counterparties?

thoughts?
