Questions?

Andrei Badea said ...

Often the MockDialogDisplayer used in tests will be configurable. For example, it may have a constructor taking a parameter that says whether the yesOrNo() method returns true or false. So in a test I create an instance of MockDialogDisplayer, as opposed to letting ServiceLoader or the Lookup library create it. When I hold such an instance, how do I set it as the singleton instance?

Simple answer is that Lookup.getDefault() is in fact a "meta-singleton", so you can have a testing implementation that will allow you to do what you want. I am still looking for more complex answer that would use mockito.
