    Hi,

     

    Thank you for the project.

    Well, I was not able to access your tested site (no navigation error in the browser but the page was just empty), so I replaced it with https://www.potnoodle.com in both, Keyword test and NameMapping.

    Also I changed type of the VarTemp test local variable from String to Object (as it is expected to store a reference to the found web element, but not a string).

    After that I was able to execute keyword test with this line of code for the Run Code Snippet operation:

    Aliases.browser.pageXXXURL.QuerySelector("a.login-to-load.ng-star-inserted");

    (Obviously, the test reported that nothing was found but there was no exception.)

     

    Unfortunately, test failed with the Type Mismatch error when I tried to use .QuerySelectorAll() and store search result to the VarTemp variable. I think this is because .QuerySelectorAll() returns an array and (even empty) array cannot be assigned to the keyword test local variable of either Object or any other built-in type.

    I don't know if it is possible to assign an array that is obtained as the result of the last operation to the keyword test local variable as I am almost do not use keyword testing. Maybe those who use it will be able to provide you with some piece of advice.

a) What line generates the exception?

 Right now it is on Step 4 .

 

b) What is this NewValue parameter? Where and how it is defined and used?

 I have no clue why testcomplete says "NewValue" as I had not configured it anyhwere.

 

c) I am not sure, but I think that something must be returned from the Run Code Snippet operation in order LastResult variable to be assigned a value. What if you change your line of code to

return Aliases.browser.pageXXXXXXXXXURL.panel.EvaluateXPath("//a[contains(@class, \'login-to-load ng-star-inserted\')]");

 Even if I add "return", it says return type unknown or invalid.

 

I am attaching the project.

keyword test : test 2

script - unit 7

 

here is the steps

1) access the url

2) select the button  and take its xpath.

3) use evaluatexpath function to get the total coupons who have the text

4) output message saying ("the total count of buttons whose valueis -"  xx)

Note : Rename the attahment to .zip.

    Hi Alex, 

     

    Thank you for the reply, after going thru the documentation (https://support.smartbear.com/testcomplete/docs/app-testing/desktop/windows-store/addressing-objects.html?q=evaluatexpath), I see where the problem is, 

    EvaluateXPath(), this method returns SAFEARRAY that you can't assign to any existing type of KDT variables (you also mentioned the same). With TestComplete 14.0,  internal casting allows assigning them to Tables. The resulting table has one column and one row per each object returned by EvaluateXPath().

     

    So now the script fails when I try to get the resulting object into a variable.(see screeshot attached)

    If the Keyword test is converted to a script, it fails the same steps as that of keyword test.

    Any help in resolving this issue is appreciated, I would like to know what is wrong in the code below?

     

    Error observed in code

    var LastResult;
    LastResult = Aliases.browser.page.panel.EvaluateXPath("//a[contains(@class,)]");
    Project.Variables.VarTemp.$set("Item", "", "", LastResult);
    if(Project.Variables.VarTemp != null)

     


    error thrown
    JavaScript runtime error.
    Error: Type mismatch.
    Error location:
    Unit: "TestProject1\TestProject1\Script\Unit3"
    Line: 12 Column: 30.

     

    TestCase Steps:

    Go to url : https://stopandshop.com/

    get the xpath for the text "+ load to card"

    use the evaluatexpath method to get the total.

    count the total objects that have "+load to card" label

    display output message "Total found :" xx);
