Java SoapUI Api, applying outgoing WSS to all test steps

This was a fun one. I did it with just a groovy script step but it should at least help lead you down the correct path

The following code will build a new project level outgoingWSS and put it into all WSDLTestSteps in the current project:

def project = testRunner.testCase.testSuite.project;
def WssC = project.getWssContainer();
if (!WssC.getOutgoingWssList().contains("testing")) {
 def owss = WssC.addOutgoingWss("testing");
 owss.setActor("blah");
 owss.setPassword("Test");
 owss.setUsername("Test");
  owss.setMustUnderstand(true);
}

for (ts in testRunner.testCase.getTestStepList()) {
 if (ts instanceof com.eviware.soapui.impl.wsdl.teststeps.WsdlTestRequestStep) {
  trs = ((com.eviware.soapui.impl.wsdl.teststeps.WsdlTestRequestStep)ts);
  trs.getTestRequest().setOutgoingWss("testing");
 }
}

Change the code as you need but it should lead you down the correct path
