Hi Praveen,

   You can write test class for your Batch apex in following ways:

  
1.@isTest
   private class BatchClassTest {

    static testMethod void myUnitTest() {

             Object__c  obj = new Object__c(); // initialize your object name
             obj.Field1 = value1;            // Assign field values 
             obj.Field2 = value2;
             obj.field3 = value3;
              ....................
            .......................
 
             insert obj; // insert object values


             BatchClass btclass = new BatchClass ();  // initialize your batch class name
             Test.startTest();
             Database.executeBatch(btclass ,1);   // execute your batch by calling        executeBatch and passing class instance and number of values runs in that batch
             Test.stopTest();
    }
Please let me know if you need any additional help.

Cheers,
Dhriti

Hello. 

Look at the Iterable implementation of Batch Apex (https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_batch_interface.htm) as I think that is what you want.  You can use a private List<sObject> or specify your type, then create a constructor that receives a list that it sets to the private one.  In your start() method, return the private list.
global class YourBatchClass implements Database.Batchable {
   List<sObject> batchList;
   global YourBatchClass(List<sObject> objList) {
      // modify list if necessary (e.g., trap null)
      if (objList == null) objList = new List<sObject>();      
      this.batchList = objList;
   }
   global Iterable start(Database.BatchableContext info){ 
       return this.batchList; 
   }     
   global void execute(Database.BatchableContext info, List<sObject> scope){
       // do whatever you need to prep scoped records for insert
       // insert scoped records  
   }     
   global void finish(Database.BatchableContext info){     
   } 
}

I hope that helps.

P.S. please forgive any type-o's as I didn't run this in SF, just typed here directly.  Therefore, please use this just as a template for understanding the concept.
