Instead of creating an entire frame, you create only a component, usually a `JPanel` or `Box`, which contains all the test UI.

Because the test UI is in a modeless owned dialog, it always displays above the instruction frame, switch to the test app brings up both the instructions and test UI. I don't expect it'd be used often, yet it's easy to implement.
