Greetings all:
It's flattering to be in the tread among experts :-)
In the order received:
1. Load test functionality in TestComplete. Yes, it will see an EOL, and we are currently working out the dates and associated programs. At this point, no new load testing licenses for TestComplete are available for purchase, but we will continue support for some extended period of time (to be clarified in the EOL statement). No price changes are considered for TestComplete at present time, as VUs were additional to Enteprise edition. Robert, I think you meant Universal edition, which is no longer available.
2. Inserting extracted data into an arbitrary place in a request. This has already been logged as a feature request, and I understand why it's needed. There are two options: either this makes it into the Q4 release, or it will be included later :-)
3. WCF. As to functional testing, we plan to have it in the Q4 release of TestComplete. SoapUI does not support WCF at present. I am not ready to comment on loadUI vs LoadComplete particularly regarding WCF. I will however note that loadUI is still in Beta and has not been released as a commercial product.
4. Scripts. We may introduce scripts into later versions of LC for advanced data manipulation. It is unlikely that we'll dump the tests into scripts though, so any scripts / scriptlets will be "attachments" to scenarios/tests.
Thank you for the great questions!
