How to run SoapUI project(wsdl) from eclipse

Following code invokes project and run it. But i am getting error when it executes groovy.test step at line -

def responseAsXml = context.expand( '${AIR Search (BEAPI)#ResponseAsXml#declare namespace ns1=\'http://iapi.tbotechnology.in/BookingEngineServices/BEAirService/BapiAirServiceImpl.svc/rest/search/\'; //ns1:Response[1]/ns1:Response[1]/ns1:Results[1]}' )

Eclipse code:

WsdlProject project=new WsdlProject("E:\\IAPI\\Automation\\BookingEngineAir-soapui-project.xml");
//Grab the Test suite in the project
WsdlTestSuite testsuite=project.getTestSuiteByName("TestSuite");

//Grab the testcases present in test suite
//for(int i=0;i<testsuite.getTestCaseCount();i++)
//{
// WsdlTestCase testCase =testsuite.getTestCaseAt(i);
WsdlTestCase testCase =testsuite.getTestCaseByName("LCC Domestic Oneway Direct Flight");


WsdlTestCaseRunner runner=testCase.run(new PropertiesMap(), false);

Assert.assertEquals(Status.FINISHED, runner.getStatus());
