Hi Praveen,

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

   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
             Database.executeBatch(btclass ,1);   // execute your batch by calling        executeBatch and passing class instance and number of values runs in that batch
Please let me know if you need any additional help.

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.
