compare object

I have a program that I need to check the properties of in two different states. TC only allows one object to be captured by object spy at a time.   Is there any way to do a side by side comparison...

    No additional save, just a refresh of the variable as per below.

     

     

    procedure CompareObjects;
var
tracePanel, PropertyNames, CollectionName, tfrmModifyTrace2 : OleVariant;
begin
//Get panel object
tracePanel := Aliases.SettingsNavigator.frmModifyTrace2.VCLObject('Panel3');

// Sets the name of the property collection
CollectionName := 'TracePanelProps';

// I want it to check all properties, so I leave the property name blank.
Objects.Save(tracePanel, CollectionName);

tfrmModifyTrace2 := Aliases.SettingsNavigator.frmModifyTrace2;
tfrmModifyTrace2.MainMenu.Click('Manage|Get Library Trace');
tfrmModifyTrace2.pnlLibLookup.isLibName.Keys('[Enter]');

tracePanel := Aliases.SettingsNavigator.frmModifyTrace2.VCLObject('Panel3');

Objects.Compare(tracePanel, CollectionName, true, lmMessage);

Objects.Remove(CollectionName); 

     Additionally... there is more information in the error than just "Object Compare error".  Any additional info/text would be useful.

1) Store the object properties in the first state into some sort of structure.  Could be multiple variables, could be a JavaScript object, could be an array... anything.
2) Write code to compare the properties of the object AFTER to the stored properties.

 

That's one possible scenario.

 

You could also create multiple property checkpoints... run them "before"... and run them "after".

In short... the answer to your question is... yes, it is possible.  Depends upon what implementation you want to make as to how you will implement it.  I wouldn't use image comparisons for this.

    Thanks for your reply tristaanogre. I guess I should have said:

     

    Is this currently possible with TestComplete? Or. Does TestComplete have a feature that accomplishes this?

     

    I'll look into doing that.

      The answer to that is... no, not that I am aware of.  Properties of an onscreen object are gathered in real time.  So, to compare the object properties in run time from one point to another requires creating some sort of storage and comparison as described.

        STOP THE PRESSES!!

         

        I think I figured out how to do this.

         

        1) Grab object with object spy

        2) Press the button "Highlight object in the object tree"

        3) At the top of the page select the "Save Object Snapshot" button

        4) Choose a file name BUT choose *.tcObject in the "Save as type"

        5) Choose to export All properties

        6) Change program state

        7) Repeat steps 1 through 5. Changing the file name to something else, so it doesn't over write the old one.

        8) Diff the resulting files (xml)  in the program of your choice

         

        Boom goes the dynamite!
