Guru 91 Help me with test class for batch apex?
Hi,
Can you please help me with test class
Class:
global with sharing class BatchToEndCarouselAnnouncementsScheduler extends BatchScheduler implements Schedulable
{
global BatchToEndCarouselAnnouncementsScheduler()
{
super(10 /*minutes between attempts */, 'End Carousel Announcements');
}
global void execute(SchedulableContext sc)
{
schedule(new BatchToEndCarouselAnnouncements());
}
}
Extended Class:
public with sharing abstract class BatchScheduler implements Schedulable
{
@TestVisible static final Integer MAX_CONCURRENT_BATCH = 5;
@TestVisible Integer minutesBeforeReschedule;
@TestVisible String title;
public BatchScheduler( Integer minutes, String title )
{
this.minutesBeforeReschedule = minutes;
this.title = title;
}
public void schedule( IBatchHelper helper, Integer batchSize )
{
Integer currentlyRunningBatches = [SELECT count() FROM AsyncApexJob WHERE JobType='BatchApex'
AND (Status = 'Processing' OR Status = 'Preparing')];
if( currentlyRunningBatches < MAX_CONCURRENT_BATCH )
{
BatchHandler batch = new BatchHandler( helper );
Database.executeBatch( batch, batchSize );
}
else
{
scheduleRetry();
}
}
public void schedule( IBatchHelper helper )
{
schedule( helper, 200 );
}
@TestVisible void scheduleRetry()
{
Datetime rescheduleDateTime = Datetime.now().addMinutes(minutesBeforeReschedule);
String timeForScheduler = rescheduleDateTime.format('s m H d M \'?\' yyyy');
System.schedule(title + ' ' + timeForScheduler, timeForScheduler, this);
}
}

Please try below test class
@isTest private class BatchToEndCarouselAnnouncementsSchTest { static testmethod void schedulerTest() { String CRON_EXP = '0 0 0 15 3 ? *'; // Create your test data Account acc = new Account(); acc.name= 'test'; insert acc; Test.startTest(); BatchToEndCarouselAnnouncementsScheduler obj = new BatchToEndCarouselAnnouncementsScheduler(); obj.execute(); Test.stopTest(); // Add assert here to validate result } }Let us know if this will help you

Please follow this post, it will be very helpful for you to write test class for your schedulable class:
http://amitsalesforce.blogspot.com/2017/07/how-to-write-test-class-for-scheduler.html
Just need to pass the new instance of your this class "BatchToEndCarouselAnnouncementsScheduler" to in System.schedule() inside test method given in the above link post
Let me know if you face any issue.
Thanks
