Hi All - I am trying to cover the test class for batch apex, but i could not able to cover execute method since my test record does not match the query condition in batch apex so scope does not returning record. can some one help how to cover this?

Here is my test class:
@isTest
public class TestpurgeCampaignRecords {
    static testMethod void TestpurgeCampaignRecordsMethod(){
           
          //List<CampaignMember> campaignMembers = new List<CampaignMember>();
          Contact c = new Contact(
                FirstName = 'User',
                LastName = 'Test ' );
           insert c;
           Id cMRecordId = Schema.SObjectType.CampaignMember.getRecordTypeInfosByName().get('Hypercare Customer').getRecordTypeId();
           Campaign campaign = new Campaign(Name = 'Test Campaign ',IsActive = true, CampaignMemberRecordTypeId=cMRecordId);
           insert campaign;
        
               list<CampaignMember> cmList = new List<CampaignMember>();
            CampaignMember campaignMember = new CampaignMember();
            campaignMember.ContactId = c.Id;
            //campaignMember.RecordTypeId = cMRecordId;
            campaignMember.CampaignId = campaign.Id;
            campaignMember.LeadId=null;
            campaignMember.Status = 'Open';
            campaignMember.Locked_By__c = null;
            campaignMember.Root_Cause__c ='Address discrepancy';
            campaignMember.Resolution_Status__c ='Resolved';
            //campaignMember.LastModifiedDate = System.today() - 1;
            //insert campaignMember;
            cmList.add(campaignMember);
            insert cmList;
            
   
        
        //insert campaignMembers;
        Test.startTest();
        String schTime = '0 0 12 * * ?';
        purgeCampaignRecords pcr = new purgeCampaignRecords();
        system.schedule('TestUpdateConAccJob', schTime, pcr);
        //system.AssertException;
        database.executeBatch(pcr);
        Test.stopTest();
        
    }

}
