How can I write a test class with DOM.XMLNode response?

request.setBody('<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/"><Header/><Body><login xmlns="urn:partner.soap.sforce.com"><username>' + '<userName>' + '</username><password>' + '<Password>' + '</password></login></Body></Envelope>');
    Dom.XmlNode resultElmt = (new Http()).send(request).getBodyDocument().getRootElement()
            .getChildElement('Body','http://schemas.xmlsoap.org/soap/envelope/')
            .getChildElement('loginResponse','urn:partner.soap.sforce.com')
            .getChildElement('result','urn:partner.soap.sforce.com');

    String sessionId = resultElmt.getChildElement('sessionId','urn:partner.soap.sforce.com').getText();

Test class from comment:

@IsTest 
global class Stubby implements HttpCalloutMock { 
    global HTTPResponse respond(HTTPRequest req) { 
        HttpResponse res = new HttpResponse();
        Dom.Document doc = res.getBodyDocument();
        Dom.XMLNode address = doc.getRootElement();
        String name = address.getChildElement('serverUrl', null).getText();
        String SESSION_ID = address.getChildElement('SESSION_ID', null).getText();
    }
}

It looks like you are doing a raw HTTP HttpRequest to the Partner API to establish a Session. In this case you create the test using an HttpCalloutMock.

With you Http Mock you can return whatever HTTPResponse you need.

A sample SOAP envelope response from the login method is available in PartnerLogin.

Your class that implements HttpCalloutMock needs to return the HttpResponse with a body that would otherwise come from the real service.

    string sessionBody = '<?xml version="1.0" encoding="utf-8"?>' +
'<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"' +
  'xmlns="urn:partner.soap.sforce.com"' +
  'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">' +
  '<soapenv:Body>' +
     '<loginResponse>' +
        '<result>' +
           '<passwordExpired>false</passwordExpired>' +
           '<serverUrl>https://na1.salesforce.com/services/Soap/u/10.0</serverUrl>' +
           '<sessionId>QwWsHJyTPW.1pd0_jXlNKOSU</sessionId>' +
           '<userId>005D0000000nVYVIA2</userId>' +
           '<userInfo>' +
              '<!-- ... -->' +
           '</userInfo>' +
        '</result>' +
     '</loginResponse>' +
  '</soapenv:Body>' +
'</soapenv:Envelope>';

    HttpResponse res = new HttpResponse();
    res.setHeader('Content-Type', 'text/xml; charset=utf-8');
    res.setBody(sessionBody);
    res.setStatusCode(200);
    return res;

  • Hi Daniel, I have added this code for HTTPRequest callouts. Please suggest what I need to do else?@IsTest global class Stubby implements HttpCalloutMock { global HTTPResponse respond(HTTPRequest req) { HttpResponse res = new HttpResponse(); Dom.Document doc = res.getBodyDocument(); Dom.XMLNode address = doc.getRootElement(); String name = address.getChildElement('serverUrl', null).getText(); String SESSION_ID = address.getChildElement('SESSION_ID', null).getText(); }

  • @oookkk You need to include the expected SOAP response. Or at least enough of it so you can test parse the SessionId and ServerUrl out of it.

  • Hi Daniel, Do I need to include (string )session body of SOAP response in my test class that you have mentioned ?

  • how can we parse this SOAP response in order to check in test class?

  • @oookkk Honestly, you seem to be doing it the hard way by manually creating and parsing the SOAP response. I created an alternative version of wsdl2apex that will let you just import the login method. It can even generate the test class for coverage and the mock for you if needed.
