You could either look into sub-classing TestRunner and provide a new run method, or look into subclassing and extending the TestResult object, possibly to include a member instance of your custom class inside it with a getter/setter method pair. Or something along that line. Or being a source forge project, you could pull the source and actually *change* TestRunner's behavior to do anything you want. (Not being a day-to-day user of junit, I have no idea which of those options are good, or whether there's anything better provided in the api itself. Just random ideas.)
