Want to generate a test case for a layout problem in your application? Want to dump the layout so a designer can theme it without having access to your backend? Test Code Generator is here to help you! Add the extension to your UI, open your application in debug mode and press the "T" button. In the window that popups up you will find generated Java code which reproduces the layout you are seeing. Copy the code to a new Vaadin 7 project and you are ready to go.
