[MO-java-dev] Resetting dyna mocks - new reset() method

[Vincent M. <vm...@pi...>]

Hi,

I have a requirement for introducing a reset on dyna mocks so that they
can be reused.

Here's the use case:

I am setting up a Mock InitialContext factory with:

        NamingManager.setInitialContextFactoryBuilder(
            new InitialContextFactoryBuilder() {
                public InitialContextFactory
createInitialContextFactory(
                    Hashtable environment) throws NamingException
                {
                    return new InitialContextFactory() {
                        public Context getInitialContext(Hashtable env) 
                            throws NamingException
                        {
                            // Return the mock context here
                            return context; 
                        }                        
                    };
                }
        });

The setInitialContextFactoryBuilder() is a static method and can only be
called *ONCE* in the lifetime of the JVM. Which means that it will be
shared between testXXX() tests. Thus the InitialContext mock (in "return
context") also has to be static.

The second step is to define expectations on the context mock lookup()
method so that we can return mocks. By doing this we are tying the
static context mock with the other per-testXXX() mocks...

... which means that if we have 2 test methods setting expectations on
lookup() with the same lookup name, the second test fails....

I believe this is a valid use case and that in order to support this use
case, we need to introduce a reset() method in the dynamock Mock class
to rest all expectations.

I've just committed the patch to support this reset method. If you think
we should not have a reset() method, I can always remove it.

Thanks
