TestStep is listed under WsdlTestCase on debug, however cannot be saved to project file at .saveIn()

Hi all, I've recently saved a wsdl project without any hassle, and now would like to do the similar with REST endpoints.

 

I've come up with a piece of code that can actually working up to a point; where it seems RestTestRequestStep is hold inside the RestRequest.  (observed on debug.)

wsdlTestCase.insertTestStep(testStepConfigx, -1); // it does put the test step under the test case in debug.

wsdlTestCase.getTestStepList().get(0) on debug returns a RestTestRequestStep with below config.

it has such config: 

 

 

<xml-fragment service="http://jsonplaceholder.typicode.com" resourcePath="/posts" methodName="Posts 1" xsi:type="con:RestRequestStep" xmlns:con="http://eviware.com/soapui/config" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<con:restRequest name="Step" id="a66d91c1-0189-4a08-a9bb-b1c25d22c559" mediaType="application/json">
<con:settings/>
<con:endpoint>http://jsonplaceholder.typicode.com</con:endpoint>
<con:parameters/>
</con:restRequest>
</xml-fragment>

My question is how do I persist this request step as well, into the project xml file? Currently saved file does not contain this part and once imported to SOAPUI, I cannot see any test steps or requests, below test case of the corresponding test suite.

In general, we supply WsdlTestCase a TestStepConfig, and this config supposed to be in some specific form to be persisted in a file? I haven't done such thing for wsdl projects. 

 

My code is as follows:

 

//ApplicationRunner.java
public class ApplicationRunner {

    public static void main(String[] args) throws XmlException, IOException, SoapUIException, RestRequestStepFactory.ItemDeletedException {

        String url = "http://jsonplaceholder.typicode.com/posts";
        String fileName = "project.xml";
        File projectFile = new File("fileDir/" + fileName);

        RestConfiguration restConfiguration = new RestConfiguration(RestRequestConfig.Factory.newInstance(),
                RestResourceConfig.Factory.newInstance(),
                RestServiceConfig.Factory.newInstance(),
                TestStepConfig.Factory.newInstance(),
                TestCaseConfig.Factory.newInstance(),
                RestMethodConfig.Factory.newInstance());

        TestCaseConfig testCaseConfig = restConfiguration.getTestCaseConfig();
        WsdlProject wsdlProject = new WsdlProject();
        wsdlProject.setName("restProject");
       
        WsdlTestSuite wsdlTestSuite = wsdlProject.addNewTestSuite("Suite");
        wsdlTestSuite.addNewTestCase("Case");
        WsdlTestCase wsdlTestCase = new WsdlTestCase(wsdlTestSuite, testCaseConfig, false);
 
        RestServiceBuilder serviceBuilder = new RestServiceBuilder();
        serviceBuilder.createRestService(wsdlProject, url);

        RestService restService = (RestService) wsdlProject.getInterfaceList().get(0);
        RestResource restResource = restService.getOperationAt(0);
        
        RestRequest requestx = restResource.getRequestAt( 0 );
        TestStepConfig testStepConfigx = RestRequestStepFactory.createConfig(requestx, "Step");
        wsdlTestCase.insertTestStep(testStepConfigx, -1); 
      
      /* I can even set requestContent at runtime.
           TestStep testStep = wsdlTestCase.insertTestStep(testStepConfigx, -1); // insertTestStep can be seen as of typ  RestTestRequestStep inside wsdlTestCase.getTestStepList()
           RestTestRequestStep restTestRequestStep = (RestTestRequestStep) testStep;
           restTestRequestStep.getTestRequest().setRequestContent("requestContentHere")
      */

        // attached the outputted xml project file.
        wsdlProject.saveIn(projectFile);

    }
}

//RestConfiguration.java
public class RestConfiguration {
    RestRequestConfig restRequestConfig;
    RestResourceConfig restResourceConfig;
    RestServiceConfig restServiceConfig;
    TestStepConfig testStepConfig;

    RestMethodConfig restMethodConfig;

    public RestConfiguration(RestRequestConfig restRequestConfig, RestResourceConfig restResourceConfig, RestServiceConfig restServiceConfig, TestStepConfig testStepConfig, TestCaseConfig testCaseConfig, RestMethodConfig restMethodConfig){
        this.restRequestConfig = restRequestConfig;
        this.restResourceConfig = restResourceConfig;
        this.restServiceConfig = restServiceConfig;
        this.testStepConfig = testStepConfig;
        this.testCaseConfig = testCaseConfig;
        this.restMethodConfig = restMethodConfig;
    }

    public RestRequestConfig getRestRequestConfig() {
        return restRequestConfig;
    }

    public RestResourceConfig getRestResourceConfig() {
        return restResourceConfig;
    }

    public RestServiceConfig getRestServiceConfig() {
        return restServiceConfig;
    }

    public TestStepConfig getTestStepConfig() {

    }

    }
