Need help writing a test class for batch class
All,
I have this batch class that I'm using to send emails to specific people.. But I'm not sure how I'm supposed to write a test class for it. I've done it for simple insert and update operations but I have no idea where to start from with this. Can someone help me out?
Thanks in Advance.

Here is a general framework:
@istest public with sharing class Test_sendEmailtoVolntr { /** * Create your test data here. * This method will get executed before each test method. * **/ @TestSetup static void setupData() { // create your Leap_Weekly_Curriculum__c records // create your Attachments // create your Volunteers__c records } static testmethod void testOne() { Test.startTest(); // execute the batch class sendEmailtoVolntr batch = new sendEmailtoVolntr(); Database.executeBatch(batch,1); Test.stopTest(); // this will force the batch class to finish // make assertions to ensure logic executed appropriately } /** * Test the schedulable method. * **/ static testmethod void testTwo() { Test.startTest(); // schedule the job Id jobId = System.schedule('Send Email to Volunteers', '0 0 0 * * ? *', new sendEmailtoVolntr()); Test.stopTest(); // ensure the job was scheduled successfully System.assertNotEquals(null, jobId); } }Hope that helps,
