### Question:
ModelToVLogConverter { static String toVLogPredicate(Predicate predicate) { final String vLogPredicate = predicate.getName() + PREDICATE_ARITY_SUFFIX_SEPARATOR + predicate.getArity(); return vLogPredicate; } private  ModelToVLogConverter();  static final String PREDICATE_ARITY_SUFFIX_SEPARATOR; }### Answer:
@Test public void testToVLogPredicate() { final Predicate predicate = Expressions.makePredicate("pred", 1); final String vLogPredicate = ModelToVLogConverter.toVLogPredicate(predicate); assertEquals("pred-1", vLogPredicate); }
