### Question:
EhrResolver extends AttributeResolver { public static boolean isEhrAttribute(String path){ if (path.startsWith("ehr_status") || path.startsWith("system_id")) return true; else return path.matches("ehr_id|ehr_id/value|time_created|time_created/value"); } EhrResolver(FieldResolutionContext fieldResolutionContext, JoinSetup joinSetup); Field<?> sqlField(String path); static boolean isEhrAttribute(String path);  }### Answer:
@Test public void testIsEhrAttribute() { assertTrue(EhrResolver.isEhrAttribute("ehr_id")); assertTrue(EhrResolver.isEhrAttribute("ehr_status")); assertTrue(EhrResolver.isEhrAttribute("system_id")); assertTrue(EhrResolver.isEhrAttribute("time_created/value")); assertFalse(EhrResolver.isEhrAttribute("time_created/time")); }
