    Hi Simon,


     


    The article you sent describes the approach for JScript.NET. TestComplete uses JScript for Windows Script Host. So, it won't work here.

Hi Tanya,



I did a little digging about JScript for Windows Script Host and found that there is way to control variable declaration (complete document):



"use strict";

function testFunction(){

    var testvar = 4;

    return testvar;

}

testvar = 5;



The code above would raise an exception at testvar=5;



The problem is that "use strict"; has no effect in TC. The JScript Engine version I am running is 5.8.16982.



Is there a way to enable this directive ?



Thanks
