# Testing the Subject Property Binding

After adding the ViDi Tool Editor element and binding the Subject property of the element to one or more ViDi tools, you can test the bindings by entering Test Mode.

1. In Designer, press the Test Mode button.
2. Go to the Page containing the ViDi Tool Editor element.

3. The ViDi Tool Editor should be displayed.

   If there are multiple tools, besides switching between the tool and the Database Editor, you can also switch between the tools that were added to the binding.
