### Question:
DatabaseUpdater { public static boolean updatesRequired() throws LockException { log.debug("checking for updates"); List<OpenMRSChangeSet> changesets = getUnrunDatabaseChanges(); if (isLocked() && changesets.isEmpty()) { DatabaseUpdater.releaseDatabaseLock(); log.debug("db lock found and released automatically"); return false; } return !changesets.isEmpty(); }  static void executeChangelog(); static void executeChangelog(String changelog, Map<String, Object> userInput); static List<String> executeChangelog(String changelog, Map<String, Object> userInput,
	        ChangeSetExecutorCallback callback); static List<String> executeChangelog(String changeLogFile, String contexts, Map<String, Object> userInput,
	        ChangeSetExecutorCallback callback, ClassLoader cl); static boolean updatesRequired(); static boolean updatesRequired(String... changeLogFilenames); static Boolean allowAutoUpdate(); static Connection getConnection(); @Authorized(PrivilegeConstants.GET_DATABASE_CHANGES) static List<OpenMRSChangeSet> getDatabaseChanges(); @Authorized(PrivilegeConstants.GET_DATABASE_CHANGES) static List<OpenMRSChangeSet> getUnrunDatabaseChanges(); @Authorized(PrivilegeConstants.GET_DATABASE_CHANGES) static List<OpenMRSChangeSet> getUnrunDatabaseChanges(String... changeLogFilenames); static Integer getAuthenticatedUserId(); static void setAuthenticatedUserId(Integer userId); static void reportUpdateWarnings(List<String> warnings); static void writeUpdateMessagesToFile(String text); static synchronized void releaseDatabaseLock(); static boolean isLocked(); static final String DATABASE_UPDATES_LOG_FILE; }### Answer:
@Test public void updatesRequired_shouldAlwaysHaveAValidUpdateToLatestFile() throws LockException { try { DatabaseUpdater.updatesRequired(); } catch (RuntimeException rex) { log.error("Runtime Exception in test for Validation Errors"); } }
