soapUI is a headless functional testing tool from SmartBear software. It comes in two flavors:

Two versions of soapUI

Since the free version is open-source, you can actually gain access to the full source code and modify as needed. The pro version is more user-friendly and has additional functionality including a form editor, an assertion wizard for XPath, and SQL query builder.  Also – the pro version is dirt cheap at just $349 per year. That’s thousands of dollars less than HP’s Service Test! (You can try the soapUI Pro version out for yourself free of charge for 14 days.)

For this example, I’ll be using the flight web service sample application that comes with HP Service Test 11.

You should get a green bar that says finish and both test should have green status!
