### Question:
WorkflowKernel { public static String generateUniqueID() { String id = UUID.randomUUID().toString(); return id; } WorkflowKernel(final WorkflowContext actx); static String generateUniqueID(); static String generateTransactionID(); void registerPlugin(final Plugin plugin); void registerAdapter(final Adapter adapter); void registerPlugin(final String pluginClass); void unregisterPlugin(final String pluginClass); void unregisterAllPlugins(); List<Plugin> getPluginRegistry(); ItemCollection process(final ItemCollection workitem); int eval(final ItemCollection workitem); List<ItemCollection> getSplitWorkitems(); static final String MISSING_WORKFLOWCONTEXT; static final String UNDEFINED_PROCESSID; static final String UNDEFINED_ACTIVITYID; static final String UNDEFINED_WORKITEM; static final String UNDEFINED_PLUGIN_ERROR; static final String ACTIVITY_NOT_FOUND; static final String MODEL_ERROR; static final String PLUGIN_NOT_CREATEABLE; static final String PLUGIN_NOT_REGISTERED; static final String PLUGIN_ERROR; static final String ISO8601_FORMAT; static final String UNIQUEID; static final String UNIQUEIDSOURCE; static final String UNIQUEIDVERSIONS; static final String WORKITEMID; static final String MODELVERSION; static final String TRANSACTIONID; @Deprecated
    static final String PROCESSID; static final String TASKID; static final String EVENTID; static final String ACTIVITYIDLIST; static final String WORKFLOWGROUP; static final String WORKFLOWSTATUS; static final String ISVERSION; static final String LASTTASK; static final String LASTEVENT; static final String LASTEVENTDATE; static final String CREATOR; static final String EDITOR; static final String LASTEDITOR; static final String CREATED; static final String MODIFIED; static final String TYPE; static final int MAXIMUM_ACTIVITYLOGENTRIES; }### Answer:
@Test @Category(org.imixs.workflow.WorkflowKernel.class) public void testUUID() { String uid = WorkflowKernel.generateUniqueID(); logger.info("UUID=" + uid); Assert.assertEquals(36, uid.length()); }
