My test broker sent a FIX message where one of the field was intenionally specified as
^X=123^
and the counterparty’s FIX.4.2 engine crashed
Where can I find a documented testcase which states that the counterparty should reject the message which has non numeric FIX Tag?
Is 14.f. “Receive message with a value in an incorrect data format (syntax) for a particular field identifier (tag number).” on page 53 / 63 of FIX 4.3 with Errata 20020920 - Volume 2 dated September 20, 2002 the nearest match to the testcase I am looking for? or is the 14.f test case more specific to reject for example ^44=ABCD^?
