TestComplete Evaluate Statement function equivalent

Does TestComplete have an Evaluate function equivalent?



What I'm trying to do is build a string then execute it as a function call.



So for example, if I have a function called "Start_Application" which takes two parameters, path and mode, I've built a string that looks like this



FunctionCall = "Start_Application" & "(" & Path & "," & Mode & ")"



Then I want to run:

 

Set Err = Evaluate(FunctionCall) which would be the equivalent of doing Set Err = Start_Application("C:\Test.exe",0)



Is there a way to do this?

    Yes, TestComplete has an evaluate function.  In fact, I use it frequently.  My code example below is DelphiScript but it should give you an idea of the capability.





            Document := Sys.OleObject(XML_DOM_OBJECT);

            Document.Load(BaselineDirectory + EVENT_TICKET_HOLD_BASELINE + VarToStr(Self.MessageID) + '.xml');

            Log.Message(BaselineDirectory + EVENT_TICKET_HOLD_BASELINE + VarToStr(Self.MessageID) + '.xml loaded.');

            //Create object for result

            Log.Message('Attempting to create XML node: ' + MESSAGE_EVENT_TICKET_HOLD + VarToStr(Self.MessageID));

            XML.CreateXML(MESSAGE_EVENT_TICKET_HOLD + VarToStr(Self.MessageID), Document);

            //Compare! Easy peasy. 

            Comparison := Evaluate('XML.' + MESSAGE_EVENT_TICKET_HOLD + VarToStr(Self.MessageID));

            Comparison.Options.IgnoreNodeOrder := True; 

            Comparison.Compare(Response.DOMObject);





    Now, I don't think you can use Evaluate to evaluate a function, only an object.  However, if you want do do a function call, you can do something like this.





            Result := ODT.Classes.New('eGalaxyMessage');

            Result := Runner.CallMethod('ODT' + aMessageType + 'Message.AddObjectSpecificProperties', Result);





    Hope this helps!



    P.S. Hi, gang!  I'm back... been away too long...

    Hi,



    Use the Eval or Execute function to do this. These functions are standard VBScript functions.

    In general, TC doesn't have a special function for this, but you can use native functions of the scripting language you are using.
