String projectName = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
def workspace = testRunner.testCase.testSuite.project.workspace
def project = workspace.createProject('Project33333',new File("C:\\Temp\\" + projectName + ".xml"));
WsdlInterfaceFactory.importWsdl(project, 'http://www.webservicex.com/globalweather.asmx?WSDL', true)
def suite = project.addNewTestSuite("CustomerSuite")
tc = suite.addNewTestCase("CustomerTestCases")
ts = tc.addTestStep( 'properties', 'Excel-Values' )
ts.setPropertyValue( 'PropertyName', 'value' )

def operation = testRunner.testCase.testSuite.project.getInterfaceAt(0).getOperationList()[0]

def factory = new WsdlTestRequestStepFactory()
def arr = ["PEO","USC","USCS","ASC"]
for(def x : arr){
log.info "For each Loop" + operation;
config = factory.createConfig(operation,x)
//log.info "Config:::" + config;
testStep = ts.addTestStep(config)
testStep.properties['Request'].value = '<request>someData</request>'
}

context.testCase.testSuite.project.save()
