BTW, all questionable methods of PersistenceDelegate interface are protected rather than public. Do we need to test it at all?

Mikhail, Tim, > I suggest that you raise a few examples here. The first example that comes to my mind is the RI's implementation of PersistenceDelegate for java.lang.String class. (Persistence delegate is a class that manages persistence details of his target class and is used by java.beans.XMLEncoder). RI's imeplementation just does nothing and returns null there applicable. It seems that RI guys simply created a stub class they do not actually use. Most likely they embedded String-handling logic in some other place in code. IMHO such a decision doesn't fully correspond the idea of persistence delegates as a place for persistence-handling logic. BTW, our StringPersistenceDelegateTest (point 2 in my classification) also expects some non-stub behavior from StringPersistenceDelegate. It seems that people who have created this test also don't like this aspect of the RI's implementation. :) 2006/6/14, Tim Ellison <[EMAIL PROTECTED]>: > Alexei Zakharov wrote: > > Hello to everyone, > > > > I am currently investigating tests for java.beans module. > > Great. > > > As far as I > > understand there were two separate contributions of java.beans tests > > from two different parties.
