Can someone help me writing a test class for the below?

Global class OldCaseDeleter implements Database.Batchable<SObject> {
    Public List<SObject> allRecords;
   Global Database.QueryLocator start(Database.BatchableContext BC) {
       String query = 'SELECT Id FROM Case WHERE CreatedDate = today and Exempt_From_Deletion__c = false';
       System.debug('query -> ' + query);
       return Database.getQueryLocator(query);
   }
   Global void execute(Database.BatchableContext BC, List<SObject> records) {
       List<Case> caseList = (List<Case>)records;
       Set<Id> caseID = new Set<Id>();
       for(Case c: caseList) {
           caseId.add(c.Id);
       }
       List<ContentDocumentLink> files = [SELECT ContentDocumentId, LinkedEntityId
                                          From ContentDocumentLink
                                          WHERE LinkedEntityId IN :caseId];
       Set<Id> conId = new Set<Id>();
       for(ContentDocumentLink cd : files) {
           conId.add(cd.ContentDocumentId);
       }
       List<ContentDocument> files1 = [SELECT Id, Title
                               FROM ContentDocument
                               WHERE Id IN : conId];
           allRecords = new List<SObject>();
        allrecords.addAll((List<SObject>)files1);
        allrecords.addAll((List<Case>)caseList);
        Delete allrecords;
   }
   Global void finish(Database.BatchableContext BC) {
   }
}

Hi Sajjan,

Try the following code, I hope it may be helpful for you:
@isTest
public class OldCaseDeleter_Test {
    @isTest 
public static void OldCaseDeleter_Test_Method(){
        Case con = new Case();
        con.Status='New';
        con.Origin='Phone';
        con.Exempt_From_Deletion__c=false;
        insert con;
    
        ContentVersion contentVersionInsert = new ContentVersion(
            Title = 'Test',
            PathOnClient = 'Test.jpg',
            VersionData = Blob.valueOf('Test Content Data'),
            IsMajorVersion = true
        );
        insert contentVersionInsert;
 
        
        ContentVersion contentVersionSelect = [SELECT Id, Title, ContentDocumentId FROM ContentVersion WHERE Id = :contentVersionInsert.Id LIMIT 1];
        List<ContentDocument> documents = [SELECT Id, Title, LatestPublishedVersionId FROM ContentDocument];
        
        ContentDocumentLink contentlink=new ContentDocumentLink();
             contentlink.LinkedEntityId=con.id; 
             contentlink.ShareType= 'V';
             contentlink.ContentDocumentId=documents[0].Id;
             contentlink.Visibility = 'AllUsers';
        insert contentlink;
        
        Test.startTest();
        OldCaseDeleter  x = new OldCaseDeleter();
        Database.executeBatch(x);
        Test.stopTest();
    }
}
    
I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.

Thanks,
