GEF based applications testability
Delivering a product meaning ensure general good works and
end user features non regressions between releases. How to
achieve that ?
 Manual tests
 Time and resource consuming
 Error prone
 Automatic tests
 Difficult to instantiate editPart and simulate user actions
 Need to poll UISynchronizer to execute asynchronous runnables
Why do not extend SWTBot to support GEF ?
