The above code "press button 3" on the Windows XP Calculator using technique similar to descriptive programming in QTP.

1) The button 3 is actually inside 2 Windows .

1. "UICalculatorWindow"  is the parent window
2. "UIItem3Window"  is the child window
3. UIItem3Button  is button "3" is present inside the child Window .

2) A seperate class has been created for parent window object and child window object whose properties has been initialised .

3)For the button object  the properties has been initialsed directly in the Main function which is ( public void CodedUITestMethod1() )

Remeber (Main Function in coded UI is "public void CodedUITestMethod1() " meaning the execution starts from there and also all the operation is written here).

4)The Logic in CUI as far as my understanding goes is something like this :

Ex : Lets say "W" is a Window and "B" is a button inside the Window "W" which we need to Click.

Therefore B is a child of W.

5) We need to create 2 Classes :-

   (1) is the Main Class (i.e.,  public void CodedUITestMethod1() ) and (2) is the Object Definition for the parent Class in our case "W" .

(1)  which is the Main Class contains

• Declaration of Parent Window Object "W".
