### Question:
FormulaEvaluator { public String evaluateSubtitleFormula(Vertex vertex, UserContext userContext, Authorizations authorizations) { return evaluateFormula("Subtitle", vertex, userContext, authorizations); } @Inject  FormulaEvaluator(Configuration configuration, OntologyRepository ontologyRepository); void close(); String evaluateTitleFormula(Vertex vertex, UserContext userContext, Authorizations authorizations); String evaluateTimeFormula(Vertex vertex, UserContext userContext, Authorizations authorizations); String evaluateSubtitleFormula(Vertex vertex, UserContext userContext, Authorizations authorizations);  }### Answer:
@Test public void testEvaluateSubtitleFormula() { assertEquals("Prop C Value", evaluator.evaluateSubtitleFormula(null, userContext, null)); }
