global void finish(Database.BatchableContext BC){

    }


    
        }

I'm new to development and need help writing a test class for this batch class. I have no idea where to start or end. Please help out.

Thanks,

Hi,
For any test class first thing we need to do is to insert all database records needed. So first inser records for objects like Leap_Weekly_Curriculum__c you have referred in this batch . Then simply call batch in between   Test.startTest(); and Test.stopTest(); in order to reset limits.

Here is an example from salesforce documentation.

@isTest
private class TestCleanUpBatchClass {

    static testmethod void test() {
        // The query used by the batch job.
        String query = 'SELECT Id,CreatedDate FROM Merchandise__c ' +
                   'WHERE Id NOT IN (SELECT Merchandise__c FROM Line_Item__c)';

       // Create some test merchandise items to be deleted
       //   by the batch job.
       Merchandise__c[] ml = new List<Merchandise__c>();
       for (Integer i=0;i<10;i++) {
           Merchandise__c m = new Merchandise__c(
               Name='Merchandise ' + i,
               Description__c='Some description',
               Price__c=2,
               Total_Inventory__c=100);
           ml.add(m);
       }
       insert ml;

       Test.startTest();
       CleanUpRecords c = new CleanUpRecords(query);
       Database.executeBatch(c);
       Test.stopTest();

       // Verify merchandise items got deleted
       Integer i = [SELECT COUNT() FROM Merchandise__c];
       System.assertEquals(i, 0);
    }
}

This is the test class I've written and it says::: Compile Error: Constructor not defined: [sendEmailtoVolntr].<Constructor>(String) at line 37 column 30
  
@isTest
public with sharing class Attachmentstest{
public static testmethod void Attachmentstest()
{

        Leap_Weekly_Curriculum__c record = new Leap_Weekly_Curriculum__c();
        Attachment attachment1 = new Attachment();
        Leap_Centre__c lcr = new Leap_Centre__c();
        
       lcr.Name = 'Anaikkum Karangal';

Hi
The constructor you defined is not taking any parameters so just do
sendEmailtoVolntr c = new sendEmailtoVolntr();
Database.executeBatch(c);

Hi Babu,

Thanks a lot for your elaborate responses. I'm not able to cover lines 106 - 119 on the test class. Not sure how I can bring out an error sending the email to go into that part of code. 

Any ideas? Get what I mean?
