### Question:
JsonUtils { public static ObjectMapper getObjectMapper() { ObjectMapper mapper = new ObjectMapper(); mapper.configure(DeserializationFeature.USE_BIG_DECIMAL_FOR_FLOATS, true); mapper.setDateFormat(Constants.getDateFormat()); return mapper; } private  JsonUtils(); static ObjectMapper getObjectMapper(); static JsonNode json(String s); static JsonNode json(String s, boolean systemPropertySubstitution); static JsonNode json(InputStream stream, boolean systemPropertySubstitution); static JsonNode json(InputStream stream); static JsonNode json(Reader reader); static JsonNode json(Reader reader, boolean systemPropertySubstitution); static Object valueFromJson(ValueNode node); static ValueNode valueToJson(Object value); static Object fromJson(JsonNode json); static JsonNode toJson(Object obj); static String prettyPrint(JsonNode node); static void prettyPrint(StringBuilder bld, JsonNode node); static String toJson(String[] strings); static JsonSchema loadSchema(String resourceName); static String jsonSchemaValidation(JsonSchema schema, JsonNode node); static int size(JsonNode node);  }### Answer:
@Test @Ignore public void testGetObjectMapper() { ObjectMapper expResult = null; ObjectMapper result = JsonUtils.getObjectMapper(); assertEquals(expResult, result); fail("The test case is a prototype."); }
