additional AdditionalAnswers

[GoogleCodeExporter]

It would be useful to have a couple more general purpose AdditionalAnswers:

public class ReturnsMethodName implements Answer<String>, Serializable {
   public String answer(InvocationOnMock invocation) throws Throwable {
        return invocation.getMethod().getName();
    }
}

and

public class ReturnsArgumentToStringAt implements Answer<String>, Serializable {
   // ... see details example in ReturnsArgumentAt
   public String answer(InvocationOnMock invocation) throws Throwable {
      // ... validation code
      return invocation.getArguments()[wantedArgumentPosition].toString();
   }
}

A sample use case for the first one is for implementing interfaces that 
represent resources, such as GWT com.google.gwt.i18n.client.Messages 
implementations, where we need quick distinguishable results for each result.

A sample use case for the second new Answer type is any existing use case that 
uses ReturnsArgumentAt but stringifies the result.  I have had several 
instances where both have been useful.

And of course the corresponding static methods would be great:

public static <String> Answer<String> returnsFirstArgToString();
public static <String> Answer<String> returnsSecondArgToString();
public static <String> Answer<String> returnsLastArgToString();
public static <String> Answer<String> returnsArgToStringAt(int position);

public static <String> Answer<String> returnsMethodName();

Interesting, but that may be a codebase  in your test utils. Not sure if the 
community would need that as a whole.
