Select the test suite you want the import to be inserted to.
In the lower part you'll find a list of WSDLs from the Trace Analyzer containing all WSDLs from the PState project. Browse through this list and look for the PurchaseOrder example.
With Select All you could also select all SOAP operations to be imported as test suites into the Regression Test tool. Use Select None to undo any selection.
Even erroneous test cases can be imported and can be used for regression testing (for an example see Adding an Additional Test Case).
To import test cases from other Builder projects use the Select from drop-down box.
