Check previous test step for the existence of a value

Hopefully this is something that is covered off in the existing functionality of Ready API.   I have a value in the results of Test Step B which is the Amount 742.50   <ns2:Rates> <ns2:RateTotal...

Thanks for your suggestion KarelHusa but here is an example of just one of the elements I want to inspect. You can see the [1] in the response .. but there are (in this example I am looking at) 7 entries I need to check to see if a match exists. Xpath (without writing a script) can only point to 1 value .. unless I am mistaken?

 

${AddService#Response#declare namespace ns2='http://xyz.com/schema'; //ns2:AddServiceResponse[1]/ns2:Response[1]/ns2:ServiceDetail[1]/ns2:TotalCost[1]}

    thatsthat,

    you can use XPath predicates in your assertion, such as:

     

    //ns2:BuyTotal/ns2:Amount[text() = 742.50]

     

    will select the XML element amount with a value of 742.50.

     

    You can also check the count of nodes:

     

    count(//ns2:BuyTotal/ns2:Amount[text() = 742.50]) > 0

    .

    XPath gives you multiple options to select the node, see e.g. https://www.w3schools.com/xml/xpath_syntax.asp .

      Thanks for your patience KarelHusa .. I will need to do some more reading it appears (thanks for the URL you sent) .. I attempted to implement your graceful solution with the count .. but no luck:

       

      count(//ns2:BuyTotal/ns2:Amount[text() = 742.50]) > 0

      But to no avail .. the below is what I am using to match a 'single' amount record that is being returned .. but I can't get it to 'count' up all the records and find if > 0 of them = 742.50

       

      ${FastSearchPackage#Response#declare namespace ns2='http://www.xyz.com/gateway/fire/schema'; //ns2:SearchResponse[1]/ns2:Response[1]/ns2:Suppliers[1]/ns2:Supplier[1]/ns2:Products[1]/ns2:Product[1]/ns2:Rates[1]/ns2:RateTotals[1]/ns2:BuyTotal[1]/ns2:Amount[1]}

       

      I get a 1 for 1 match .. i tried adding count blah blah but could not land the correct answer!!

       

       

      I did also try with an 'Count' xpatj expression

       

      declare namespace ns2='http://www.xyz.com/gateway/fire/schema';
${FastSearchPackage#Response#declare namespace ns2='http://www.xyz.com/gateway/fire/schema'; //ns2:SearchResponse[1]/ns2:Response[1]/ns2:Suppliers[1]/ns2:Supplier[1]/ns2:Products[1]/ns2:Product[1]/ns2:Rates[1]/ns2:RateTotals[1]/count(ns2:BuyTotal[1]/ns2:Amount[text()=742.50])>0}

       

      But no joy.

        thatsthat,

        relying on a fixed position (using indexes in your XPath) in XML may be fragile. Next time you may get additional elements, and your XPath will no longer work.

         

        That's where a query helps.

         

        What kind of response do you get if you test the following expressions:

         

        //ns2:BuyTotal/ns2:Amount[text() = 742.50]

         

        count(//ns2:BuyTotal/ns2:Amount[text() = 742.50]) > 0
