question: public void test_filter ( ) { final FilterBase fixture = new MockFilterBase ( ) ; final Object context = new Object ( ) ; final Iterator src = EmptyIterator . DEFAULT ; final MockIterator actual = ( MockIterator ) fixture . filter ( src , context ) ; assertNotNull ( actual ) ; assertTrue ( "src" , actual . src == src ) ; assertTrue ( "context" , actual . context == context ) ; assertTrue ( "filter" , actual . filter == fixture ) ; }
target:  Test creation of iterator without filter chain. make sure that the context is passed through.
