What issues can occur with clients integrating their front end systems with a web service?
We recently underwent a migration of our IBM connect solution from a public platform to a dedicated platform. We were using SoapUI Pro NG to functionally regression test all of our APIs.
A number of live customers encountered issues that were not picked up by our testing. These were around the use of TLS profiles that were not supported by the upgraded platform and customers using java 7 or below, which doesn't support the SNI extension to SSL.
We were able to replicate the TLS issue by modifying the 'SoapUI-5.3.0.vmoptions' file. To check the APIs using different TLS profiles didn't occur to us at the time of testing (perhaps it should have).
My general question is what other issues could occur for customers integrating to a web service that may not necessarily be picked up by testing with SoapUI NG Pro? What other things should be considered other than those listed above.
