Web Services and QTP – Part 2: Web Service Testing Wizard

by | Last Updated On Aug 7, 2014 | Advanced Concepts, Web Services | 31 comments

In the earlier part of WebServices testing with QTP, we have gone through the basic concept required for web service testing. In this part we will use those concepts to test the web service using QTP.

When you are about to test a web service, make sure you have enabled Web Service Add-in for QTP. Once you have the add-in properly loaded you will see web service pane at Test Settings and Options. Web services toolkit option enables you to select a toolkit you want QTP to use for web service operations. For new tests and components, the default toolkit is the same as the toolkit set in the Web Services pane of the Options dialog box for learning Web Service objects.

QTP performs validation using the WS-I validation tool. The Web Services Interoperability Organization (WS-I) is an open industry organization chartered to establish Best Practices for Web services interoperability, for selected groups of Web services standards, across platforms, operating systems and programming languages. You will need to specify the path of validation tool in web services pane at option, and then you can access the tool by selecting Tools > validate WSDL.

Let us now see Web Service Testing Wizard in QTP. To open the wizard click the web services wizard in toolbar or select Automation > Web Service Testing Wizard.Web Services Testing Wizard Menu

You will see a Welcome screen which provides you the overview of wizard. You can choose whether you want the welcome screen when running the wizard or not.

Clicking on Next button you will get the screen for WSDL Scanning. Here you will need to specify the WSDL, which can be a URL, a WSDL file or it could be in your repository which has added earlier. Select the Include security settings in the generated Web service test check box if you want to specify the security tokens that are required for communication with the Web service you want to test.Specify WSDL for Scanning

Click Next, the next screen that pops up is depending on your selection in the last screen. If you have specified a secure WSDL, the Network Credentials dialog box opens. Enter the login details required to access the WSDL and click OK. The Web Service Testing Wizard – Set Security Options Screen opens. If you selected the Include security settings in the generated Web service test check box, the Web Service Testing Wizard – Set Security Options Screen opens. If you do not need to specify security settings, the Web Service Testing Wizard – Select Service and Operations Screen opens.

Specify the WSDL from W3Cschools.com which I have mentioned in the last part http://www.w3schools.com/webservices/tempconvert.asmx?wsdl . Clicking on Next, Select Service and Operations Screen opens.Select Service and operations

You will see the two operations here select one of the operations and move it to selected Operations list. And click next. The next screen comes is the Summary screen. You can automatically insert XML checkpoints by selecting Add XML checkpoint after each relevant step (selected by default). Selecting this check box adds an XML checkpoint for each step in the test that has a return value or an output argument.Web Services Test Wizard Summary

Click Finish and The WebService test object is stored in the local object repository, and the defined steps are converted to the proper syntax and inserted into your test.

Go to your Object repository. You will see your web services test object and the xml checkpoint added. Selecting the test object, you can see the details of this object like wsdl, port, and service. You can see the following script generated in your test.

CelsiusToFahrenheit= WebService("TempConvertService").CelsiusToFahrenheit("string (Autogenerated)")
WebService("TempConvertService").Check CheckPoint("CelsiusToFahrenheit")

You can see that the parameters are not yet passed, it is auto generated by the wizard (“string (Autogenerated)”), and you will need to specify this parameter before executing this. Something like below and execute.

CelsiusToFahrenheit = WebService("TempConvertService").CelsiusToFahrenheit("25")
WebService("TempConvertService").Check CheckPoint("CelsiusToFahrenheit")

In the Test Result you will find that your test failed. Click on Web Service object you can see the SOAP request and response there as described in the last part.

Response Result

The web service has actually output the result in the response i.e. 77; actually it has failed at check point.

XML Check point result view

This is because we have not configured the xml checkpoint for the expected result. So if you have selected to add xml checkpoint at wizard then make sure you have configured it.

Note:-

  • Make sure you run Web service tests using the same toolkit with which the test was created.
  • QTP includes Maintenance Run Mode, which is not supported for applications such as Web services, which do not have a user interface.
  • WSDL Validation tool is a third-party application that is not provided with QuickTest. You can download Interoperability Testing Tools 1.1 from the Web Services Interoperability Organization Web site at http://www.ws-i.org and it must be installed locally.

    Hello Saket,

    I’m new to QTP Web service testing and found a little issue. I’ve installed the Web Service Plug-ins but after a test is completed and in result I can’t see my SOAP Request and Response (like you showed). Am I missing something?

    Many thanks in advance.

    Hi Saket,

    Very useful information Saket. I have tested webservices till now only using SOAP UI Manually, but now I’ve been given a task of automating, I am new to QTp still a beginner. Before that do you think QTP is the best tool for automation testing SOAP & REST services?

      Actually No now, As I think HP does not have plans to continue support for Webservice addin in QTP. It has actually the tool HP -Service Test specially for this purpose. REST, I am not sure if it is good in HP Service Test but other than this it works good. This has now been integrated into UFT 11.5

    Hi Saket,

    Please let me know if QTP supports WCF services.
    Also provide me the info on adding a endpoint to WCF WSDL.

    Thanks,

    It looks like a network restriction on your computer, are you able to access w3schools webservice directly on your browser?

    Hi Saket,
    Firstly thanks for the nice article.
    I was trying to experiment with the WS add-in, but seem to have run into some issue. I am trying to follow the same steps mentioned above, but once I provide the WSDL path(URL from the w3schools), QTP is throwing an error saying – Proxy authentication required. Can you please let me know if I am missing something here?
