Instead of manually changing property values, you can create and run a data transform that sets the values defining a test case.
    - 
        Save the Declare Expression rule form.
      
- 
        Select .
      
- 
        From the Data Context list, select the context in which to run
          the test.
      
- 
        Specify a data transform to run by clicking the hyperlink.
      
- 
        Click Reset Page to discard all previous test results.
        An empty test page is re-created, and your data transform reinitializes your specified
          values. 
- 
        Repeat steps 4 through 5 with other data transforms, or alter the clipboard contents
          and repeat the test.
      
- 
        If the unit test of the Declare Expression rule requires creating an input that is part
          of an embedded Page ListorPage Groupproperty, create
          a new page by performing the following actions:
          - 
            Select the Add new page check box.
          
- 
            For a Page Group, enter an identifier as subscript value (For aPage List, the system appends the new page after existing
              pages.)
- 
            From the Class list, select the class of the page.
          
- 
            Click Update.
          
 You can also add inputs to Value ListorValue Groupproperties.
