Batch Apex - How to write the test class?

use this
  
@isTest
private class LoanOfficerBatchTest {

static testMethod void exTest1(){
 Date startDate = Date.today().addDays(-2);
Contact c   = new Contact();
c.FirstName = 'Stephen';
c.LastName  = 'Curry';

insert c;

Lead ls =new Lead(Company = 'JohnMiller', LastName = 'Mike', Status = 'Open' ,Loan_Officer_1a__c =c.Id);
insert ls ;
Test.setCreatedDate(ls.Id, startDate);



Lead ls1 =new Lead(Company = 'JohnMiller', LastName = 'Mike', Status = 'Open' );
insert ls1 ;
Test.setCreatedDate(ls1.Id, startDate);
Lead myLead = new Lead(LastName = 'Fry', Company='Fry And Sons');

Test.startTest();
LoanOfficerBatch lo=new LoanOfficerBatch();

Database.executeBatch(lo);

1. Setup the data.
2. Test.startTest()
3. Invoke the batch class.
4. Test.stopTest()

You're done. Just keep in mind that there should be exactly 1 batch to execute. If your batch class creates more than 1 batch, it would throw an error in test class.

For e.g.
Test.startTest();
MyBatchClass obj = new MyBatchClass();
Database.executeBatch(obj); 
Test.stopTest();

Just create the test data before these and ensure there would only be 1 batch created to be passed to execute() from start().

I have create this one but the code coverage is only 12% can you please help.There is only 1 batch
JayantJayant
You need to create proper and enough data for all lines to be covered. You don't seem to be having any converted lead while your code is actually driven by converted leads.
Convert a few leads before executing your batch. You can convert using apex, link below -
https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_dml_convertLead.htm 
Muhammad Jawwad 16Muhammad Jawwad 16
if you don't mind can you please do it for me?
 
JayantJayant
Nope.
Just copy the code from the link and tweak it. Convert the lead ls that you are already creating and you may be done with it.

I have copy and paste this but nothing could happen.

Change your code as below
  
@isTest
private class LoanOfficerBatchTest {

	static testMethod void exTest1(){
		 Date startDate = Date.today().addDays(-25);
    	Contact c   = new Contact();
       c.FirstName = 'Stephen';
       c.LastName  = 'Curry';
       c.Email     = 'stephcurry@gsw.com';
       insert c;
	   
		Lead ls =new Lead(Company = 'JohnMiller', LastName = 'Mike', Status = 'Open' ,Loan_Officer_1a__c =c.Id);
		insert ls ;
		Test.setCreatedDate(ls.Id, startDate);
        

		
		Lead ls1 =new Lead(Company = 'JohnMiller', LastName = 'Mike', Status = 'Open' );
		insert ls1 ;
		Test.setCreatedDate(ls1.Id, startDate);
        Lead myLead = new Lead(LastName = 'Fry', Company='Fry And Sons');
         insert myLead;

        Database.LeadConvert lc = new Database.LeadConvert();
        lc.setLeadId(ls.id);
		LeadStatus convertStatus = [SELECT Id, MasterLabel FROM LeadStatus WHERE IsConverted=true LIMIT 1];
        lc.setConvertedStatus(convertStatus.MasterLabel);

        Database.LeadConvertResult lcr = Database.convertLead(lc);  
        System.assert(lcr.isSuccess());


		Database.LeadConvert lc1= new Database.LeadConvert(); 
lc1.setLeadId(ls1​​​.id);
lc1.setConvertedStatus(convertStatus.MasterLabel); 
Database.LeadConvertResult lcr1 = Database.convertLead(lc1);​​​​​​​
		
		Test.startTest();
		LoanOfficerBatch lo=new LoanOfficerBatch();
		lo.objName ='Lead';
		Database.executeBatch(lo); 
		Test.stopTest();
	}
}
