Hello friends, I have a schedulable class.

global class SchedulableTNOFTPJob implements Schedulable {
    global void execute(SchedulableContext sc) {
    if ([SELECT count() FROM AsyncApexJob WHERE (JobType='BatchApex' OR JobType='ScheduledApex') AND (Status = 'Processing' OR Status = 'Preparing')] < 5){
            try {
              //for(Integer i=0; i < 50; i++) {
              Datetime sysTime = System.now();
              ProcessTNOFiles batch = new ProcessTNOFiles();
              Id cronId = System.scheduleBatch(batch, 'schedFiles' + sysTime.getTime(), 1);     
              //}
            } catch (System.AsyncException ae) {
              
            }
        } else {
          System.debug(LoggingLevel.WARN,'ProcessTNOFiles Finished');
          //Build the system time of now + 20 seconds to schedule the batch apex.
          Datetime sysTime = System.now();
          Integer rand = Integer.valueOf(Math.Random() * 10);
          sysTime = sysTime.addSeconds(20+rand);
          String chron_exp = '' + sysTime.second() + ' ' + sysTime.minute() + ' ' + sysTime.hour() + ' ' + sysTime.day() + ' ' + sysTime.month() + ' ? ' + sysTime.year();
          system.debug(chron_exp);
          SchedulableTNOFTPJob ftpFiles = new SchedulableTNOFTPJob();
          //Schedule the next job, and give it the system time so name is unique
          Id cronId = System.schedule('ftpFiles' + sysTime.getTime(),chron_exp,ftpFiles);
          System.abortJob(sc.getTriggerId());
          System.debug('*******ProcessTNOFiles FAIL CRON ID: '+cronId+', but MAIN ID: '+sc.getTriggerId());
        }
    }
}

and it's test class is here

@isTest
public class TestSchedulableTNOFTPJob {
    
    static testMethod void myUnitTest() {
    test.startTest();
        AsyncApexJob aa = new AsyncApexJob();
       
	SchedulableTNOFTPJob nightlyUpdate = new SchedulableTNOFTPJob();
	String schedule = '0 0 23 * * ?';
	system.schedule('Nightly Update', schedule, nightlyUpdate);
        
	test.stopTest();
    }
}

But the test class is covering only "IF" condition of schedulable class.Please help. Thanks in anticipation :)

I need to show warning message when user close[X] the flow. It is working fine, but it is also showing warning message when click on the pause button and next button. This should not be happening.
 Here is my code :-

    <script type="text/javascript">
     window.onbeforeunload = function() {
       
        return "Did you save your stuff?"
      }
    </script>

<flow:interview name="ClientIntakeFlow_FROM_CONTACT" allowShowPause="true" finishLocation="{!PageA}" pausedInterviewId="{!pausedId}" rendered="{!displayBoolean}">
<apex:param name="ClientIdVar" value="{!Contact.Id}"/> </flow:interview>
