question: public void testSingleSentences ( ) throws Exception { BreakIterator expected = BreakIterator . getSentenceInstance ( Locale . ROOT ) ; BreakIterator actual = new WholeBreakIterator ( ) ; assertSameBreaks ( "a" , expected , actual ) ; assertSameBreaks ( "ab" , expected , actual ) ; assertSameBreaks ( "abc" , expected , actual ) ; assertSameBreaks ( "" , expected , actual ) ; }
target:  For single sentences, we know WholeBreakIterator should break the same as a sentence iterator
