Need help in writting Test Classes

Hi,
I have a test class that deletes custom object record  at the end of day if the value of Grand Total field is 0.

Grand Total field is a roll up field, and is calculated basis the line item value.

Here is my batch class.

global class ProductInterestDeleteBatch implements Database.Batchable<sObject>,Schedulable{
    
    global void execute(SchedulableContext sc){
        ProductInterestDeleteBatch bc = new ProductInterestDeleteBatch();
        database.executeBatch(bc);
    }
    global Database.QueryLocator start(Database.BatchableContext bc){
        return database.getQueryLocator([SELECT Id FROM Product_Interest__c WHERE Grand_Total__c=0]);
    }
    global void execute(Database.BatchableContext bc,List<Product_Interest__c> productInterestList){
        if(!productInterestList.isEmpty()){
            database.delete(productInterestList,false);
        }
    }
    global void finish(Database.BatchableContext bc){
        
    }

}



I need help in writting test class for the same.

Hi Sid,

Greetings to you!

Please try the below code, I have tested in my org and it is working fine. Kindly modify the code as per your requirement.
  
@isTest
public class Test_ProductInterestDeleteBatch {
    
    static testmethod void TestMethod1(){
        Product_Interest__c pi = new Product_Interest__c();
        pi.Name = 'Test Prod';
        // Add other required fields
        INSERT pi;
        
        Test.startTest();
        
        ProductInterestDeleteBatch obj = new ProductInterestDeleteBatch();
        
        String cronExpr = '0 0 0 3 9 ? 2022';
        String jobId = System.schedule('myJobTestJobName', cronExpr, obj);
        obj.execute(null);
        
        DataBase.executeBatch(obj); 
        
        Test.stopTest();
    }
}

I hope it helps you.

    @isTest private static void testProductInterestDeleteBatch()
    {
        Product_Interest__c prdInt=new Product_Interest__c();
        prdInt.Name='test';
        prdInt.Grand_Total__c=0;       
        insert prdInt;
        
        
        Test.startTest();  
        
        ProductInterestDeleteBatch obj = new ProductInterestDeleteBatch();
        DataBase.executeBatch(obj); 
        
        ProductInterestDeleteBatch m = new ProductInterestDeleteBatch();
        String sch = '20 30 8 10 2 ?';
        String jobID = system.schedule('Merge Job', sch, m);
