All about SOAP UI and Groovy in it

Assertions are generally the simple and most sought validations that can be enforced in SOAP UI.

For SOAP response we have an assertion step called ‘XPath Match‘, which validates the value yielded by the specified xpath with the one provided staticly.

When we add ‘XPath Match’ assertion using the Add Assertion button, we see the below window.

XPath Match Assertion

XPath Match Assertion

There is a button called ‘Declare‘ (present in free version of SOAP UI also), it automatically declares all the namespaces of SOAP response. After declaring the namespaces using this ‘Declare’, mention the xpath of the node whose value is to be validated. Here the xpath could start from the node which comes just after the <soap:Body> node (i.e., <soap:Body> node’s immediate child). For example, if say the response xml is:

Sample Response

Sample Response

then to validate on the value of ‘Status‘ node, the xpath that should be present in XPath Expression blockalong with all the declared namespaces is

//p77:GetReportResponse/p77:GetReport/ReportResponse/Status

And, now we need to provide some expected value, inside ‘Expected Result’ block which shall validated against the corresponding node value. There is an option called ‘Select from current‘, which actually fetches the value of that xpath, from the current response. Another option called ‘Test‘, is used to test right away.

  1. Hi…I have a small question.

    Suppose for the given below response I want to get value of “returnedItems” using Xpath. How I will get that value.

    SOAP-ENV:Envelope xmlns:SOAP-ENV=”http://schemas.xmlsoap.org/soap/envelope/”>

    Item1

    • Hi Sandeep,

      Might be an oversight or misapprehension by the site, I see an incomplete SOAP response in your comment above.
      Could you send me that response again, so that I can help.

      Thanks

    I have a question,

    I use SoapUI 2.5. After I added XPath match Assertion step and just let SoapUI automatically declared all namespaces from the response XML, I kept getting the assertion error:

    RuntimeException:net.sf.saxon.trans.XPathException: XPath syntax error at char 0 in {}: Unexpected token “” in path expression.

    Do you know why? Thx.

  3. Decalare required namespaces there, issue will be resolved

  4. Hi,

    After declaring the Name space by using the declare option from tool and from the expected result i i selected the option ” select from current” than i got below mentioned error message..

    “java.lang.RuntimeException: net.sf.saxon.trans.XPathException: XPath syntax error at char 0 in {}: Unexpected token ” ” in path expression”

    Thanks in Advance

    • Hi,
      I am learning soapUI,Please explain the Xpath Match assertion and XQury assertion with right example.(i mean free WSDL available from the net).

      I tried the following example.
      WSDL:http://www.webservicex.net/globalweather.asmx?wsdl

      Request

    • Hi

      Having the same issue as Mahesh. He said ““java.lang.RuntimeException: net.sf.saxon.trans.XPathException: XPath syntax error at char 0 in {}: Unexpected token ” ” in path expression”

      Emilia Ipate then replied saying “Clear explanation. Put on practice (took only 5 minutes).

      After having through the rest of the page, please can you explain where the explanation is that Emilia is referring to so I too can put this in practice within 5 minutes.

      Thanks

    Hi can anybody help me how to create dummy logins and password using groovy and vlidate them using xquery assertions,
    Thanks in advance

  7. Is it possible to select nested XML using XPath? I have the following that I need to play with:

    <![CDATA[

    … and so on.

    I’m tried //ReplyXML/xml
    //ReplyXML/?xml
    //ReplyXML/ CDATA

    and many others.

  8. I am currently facing the same problem…
    basically tag means “Content Data”
    that will be ignore by XPath,
    so the only way seems to be trim them by program…

  9. Hi ,

    I need to take out a value from a Node in Response and Compare it against value from the request. I am able to use XPATH assertion to get to value from Response . How can i take out the value from the request to comapre with this ? what is syntax for pointing to request in the XPATH assertion expression?

    • Hi Praveen,

      You want to compare a request node value to response node value, for which instead of XPath Match/Assertion try using Script assertion.

      In Script assertion, using messageExchange and context variables we can get hold of request/response xml and thus comapring the required node values with assert statement would do your job.

      Hope this helps.

      Thanks,
      Devakara.

  10. Praveen said:

    Pls let me know what is the basic differnce between XPath and Xquery assertions?

  11. jimkitsos said:

    In the sample response you have provided in the example, is it possible to get the ‘RefNum’ only if the ‘Status’ is ‘OPERATION SUCCESSFUL’?

    • devakara said:

      Hi,

      XPath Assertion doesn’t return you any Value; it just validated your response, with the provided XPath and value – results an Assertion success/failure.

      If you want to do some operations with the RefNum, based on some conditions, you should instead use Script Assertion – that would provide you more control.

      Hope this helps.

      Thanks,
      Devakara.

      • jimkitsos said:

        Hi Devakara,

        Thank you for the reply. I used a groovy script to do what I needed.

      Hi,

      I am afraid I can’t understand your XML and I know its not your fault.
      But anyway could you use some online notepads to share your XML (maybe something like http://shrib.com/). From there we can all have a look at the XML and help find a solution for your problem.

      Hope this helps.

      Thanks,
      Devakara.

    Hi Devakara,
    I am new to soapUI. I need to do a simple thing – set a value for username and validate different scenarios through soapUI. I have set a value through a property: ‘username’, now in property transfer step, selected the property name as source and ‘username’ for the property. And for the target selected the soap request and ‘request’ for the property. I have not entered anything in the Xpath. Now when I am running the steps:property,property transfer,soap request…then the total soap request is getting replaced by the property value.

    What should I need to do to change only the required attrobute value in the soap request with the property value?
    please help…

  14. Hi,

    After declaring the Name space by using the declare option from tool and from the expected result i i click on the “Test” botton…I didn’t get any response..it shows some error…
    Help me how to solve this problem.

  15. http://www.webservicex.net/globalweather.asmx?wsdl

    I am getting the error for above wsdl when iam using the Xpath assertion…

    XPathContains assertion failed for path [declare namespace ns1='http://www.webserviceX.NET'; declare namespace soap='http://www.w3.org/2003/05/soap-envelope';] : RuntimeException:net.sf.saxon.trans.XPathException: XPath syntax error at char 0 in {}: Unexpected token ” ” in path expression

    • Hi Nani,

      If I’m not wrong, it seems you didn’t mention any XPath itself, so as to match it with your expected result.
      Do declare an XPath, probably like

      //ns1:GetCitiesByCountryResponse/ns1:GetCitiesByCountryResult

      for the XPath assertion in GetCitiesByCountry test request and check the expected result.

      Hope this helps.

      Thanks,
      Devakara

  16. How to compare the response values and the database values.plz send the code to me along with some example.

  17. Hi Devakar,

    thank u for reply..but the xpath is not working for above example what u explain.When i click on declare button and select some path after that i click on test botton it is showing some error…
    The declare code is

    declare namespace ns1=’http://www.webserviceX.NET’;
    //ns1:GetCitiesByCountryResponse[1]/ns1:GetCitiesByCountryResult[1]

    after click on test button the error code is :

    XPathContains assertion failed for path [declare namespace ns1='http://www.webserviceX.NET'; //ns1:GetCitiesByCountryResponse[1]/ns1:GetCitiesByCountryResult[1]] : Exception:org.custommonkey.xmlunit.Diff [different] Expected namespace URI ‘null’ but was ‘http://www.webserviceX.NET’ – comparing at /NewDataSet[1] to at /GetCitiesByCountryResult[1]

    Tell me the difference between the test and select button in Xpath.

  18. Hi Devakar,
    Still you didn’t give any reply to my question.Plz tell me what are the possible ways to compare the database values any the response values.
    Send the code and example. The above given reply code also not working.

  19. Wonderful and simple explanation thanks a lot

  20. How to parameterise the valueexpected value in the XPATH match assertion?

  21. Hi

    I would like to validate in my response whether at least one parameter with right value exists. How can achieve this .

    Eg: Trying to create a user with emailid. In my tests i am using an email id and for the first time user will be created and tests pass as the assertion is against only the status is ok or not. from 2nd time onwords, the assertion fails as the out put is duplicate user. I want to assert this as success as well irrespetive of 1st attempt or nth attempt. So , i wanted to check for status is ok or error msg is ‘Duplicate’.
    ls some one help in achieving this.

    Thanks
    Raj

    • Hi Raj,

      When there are multiple node values to be validated in the response, you could use Script assertion.
      In Script assertion, you could fetch all the node values you want and validate them against the string constants (‘Success’ or ‘Duplicate’).
      Do look at this post for more help on Script assertion.

      Hope this helps.

      Thanks,
      Devakara.

  22. Hi
    Does the namespaces are nessessary in assertion?
    I tried to declare namespaces by using button “Declare” in XPath Match but nothing was happen. There are no tag ‘xmlns’ in my response. Can I use my assertion without namespaces?

    • Hi Yulka,

      I think your response will atleast have the xmlns for soap tags. And if the parent node in the response body is not associated with any namespace, then you should be able to create the XPath Match assertion without namespaces.

      Do let us know, what worked for you.

      Hope this helps.

      Thanks,
      Devakara.

  23. I have a problem here, I need to check a message for certain contents, but I get 5 messages and the sequence of those are not Always the same. I tried to get xpath, but all get get is a blank window, I can’t put in an xpath. I also tried a conditional goto, but can’t read the correct contents as well.
