Hey
shockwave,
You could strictly speaking submit an HTTP POST method to your endpoint's listening API to emulate your two defined testcases using ReadyAPI!/SoapUI, but you would need to determine from your system's requirements the different parameters associated with the URI your endpoint is expecting to do this, but again my question still stands....why do you think you need to do this via ReadyAPI! rather than use a front end capture/playback tool?
Youve posted your query in the ReadyAPI!/SoapUI forum which doesnt support front end testing.
Has someone told you, you need to use ReadyAPI!/SoapUI to do your testing?
Without answering the above questions we're not going to be able to help you.
Cheers,
Rich
