Hi Charu ,
this batch , i am calling in schedulable batch class . the above mentioned test class would work?
and in my batch class i am updating child opportunities from parent opportunities

Hii Mayank 
As you said In Your Batch You're Update Child opportunities From Parent Opportunities
In Below Test Class i'm Inserting  One Parent Opportunity ANd one Child Opportunity Rest You Have To Fill The Required Fields

you Have to Change The name of ScheduleClass In Below code 
 public Class CompositeOppbatchClsTest{
public static String CRON_EXP = '0 0 0 2 6 ? 2022';
public Static Void UnitTest(){
Id RecordTypeId = Schema.SObjectType.Opportunity.getRecordTypeInfosByName().get('Air Composite Opportunity').getRecordTypeId();
Account Acc =New Account (); = 'Test Acc';
insert Acc;
Opportunity Opp = new Oppotunity();
opp.Name ='test opp';
opp.AccountId =;
opp.Composite_Opp_Check__c  = false;
opp.RecordTypeId  = RecordTypeId ;
/*Fill All Required Fields*/
Insert Opp;
Opp.Status__c = 'Approved';
update opp;

Opportunity Opp2 = new Oppotunity();
opp.composite_opportunity__c = opp.Id;
/*Fill All Required Fields*/
Insert Opp2;

     String jobId = System.schedule('test', CRON_EXP, new ScheduleClassName());
Please Mark It As Best Answer If It Helps
Thank You!

Please find the solution.

 public Class CompositeOppbatchClsTest{
public static String CRON_EXP = '0 0 0 2 6 ? 2022';

 Static testmethod Void UnitTest(){
Id oppRecordTypeId = Schema.SObjectType.Opportunity.getRecordTypeInfosByName().get('Air Composite Opportunity').getRecordTypeId();
Account ac =New Account ();
ac.Name = 'Test Data';
insert ac;
Opportunity oppInstance = new Oppotunity();
oppInstance.Name ='opp Data';
oppInstance.AccountId =;
oppInstance.RecordTypeId  = oppRecordTypeId ;
//oppInstance=> Fill aur required field
 Insert Opp;
oppInstance.Status__c = 'Approved';
update opp;

Opportunity oppInstance2 = new Oppotunity();
oppInstance2.composite_opportunity__c = opp.Id;
//Similarly fill this oppInstance2
 Insert Opp2;

     String jobId = System.schedule('test', CRON_EXP, new ScheduleClassName());
Thank you

Hi Charu,

I have one doubt here. i am using this chrone expression in my scheduler class - '0 0 0,4,8,12,16,20 ? * *'  
should i use the same one is test class also?

@ Mayank 
No It's Not Necessary As Chrone Expression In test Class Is For Just Testing Purposes

Thank You!
