Help in Test Class for Batch Class

Hi Experts,

Please find below batch class i need test class. Please anyone help me regarding this. Thanks in advance.

global class SendPartnerGroupRequirementsBatch implements Database.Batchable<SObject>
{
   global static String response{get; set;}
   global List<Request__c> objLstRequest{get;set;}
   
    public SendPartnerGroupRequirementsBatch(List<Request__c> lstReq)
    {
        objLstRequest = lstReq;
    }
    global Database.QueryLocator  start(Database.BatchableContext bc) 
    {
        String query = 'SELECT Id FROM Request__c where Id in :objLstRequest';
        return Database.getQueryLocator(query);
    }
    global void execute(Database.BatchableContext BC, List<Request__c> scope)
    {
        for(Request__c objReq : scope)
        {
            response = WorkflowUtil.submitRequest(objReq.Id);
            String requestId= objReq.Id;
            if (response == 'Success') 
            {
                System.Queueable job = new SendPartnerGroupRequirementsBatchHandler(requestId);
                System.enqueueJob(job);
            }
        }
        
    }
    global void finish(Database.BatchableContext BC)
    {
        
    }

}

Try this and let me know any issues

@isTest
private class TestSendPartnerGroupRequirementsBatch {

    static testmethod void test() {
        // The query used by the batch job.
        String query = 'SELECT Id FROM Request__c where Id in :objLstRequest';

       // ********************* Create some test merchandise items to be deleted
       //   by the batch job.
       Request__c reqList = new List<Request__c>();
       for (Integer i=0;i<10;i++) {
           Request__c req = new Request__c( Name='request ' + i, numnber = i );
           reqList.add(req);
       }
       insert reqList;
       // Or Create a single record
       Request__C req1 = newRequest__C();
       req1.name ='sdfgds';
       insert req1;

       //Star the test
       Test.startTest();
       SendPartnerGroupRequirementsBatch btch = new SendPartnerGroupRequirementsBatch(query);
       Database.executeBatch(btch);
       Test.stopTest();

       // Verify If batch job done nice
       String response = WorkflowUtil.submitRequest(req1.Id);
       System.assertEquals('Success', response);
    }
}

If you want to learn about test classes. Please check below post
1) http://amitsalesforce.blogspot.in/search/label/Test%20Class
2) http://amitsalesforce.blogspot.in/2015/06/best-practice-for-test-classes-sample.html

Please try below code. I hope that will help you 
@isTest
private class SendPartnerGroupRequirementsBatchTest 
{
    static testmethod void test() 
	{
		List<Request__c> lstReq = new list<Request__c>();
		Request__c req = new Request__c();
		req.name ='demo';
		// add all required field here
		insert req;
		
		lstReq.add(req);		
	
	
		Test.startTest();
			SendPartnerGroupRequirementsBatch btch = new SendPartnerGroupRequirementsBatch(lstReq);
			Database.executeBatch(btch);
		Test.stopTest();

    }
}
Please follow below salesforce Best Practice for Test Classes :-

1. Test class must start with @isTest annotation if class class version is more than 25
2. Test environment support @testVisible , @testSetUp as well
3. Unit test is to test particular piece of code working properly or not .
4. Unit test method takes no argument ,commit no data to database ,send no email ,flagged with testMethod keyword .
5. To deploy to production at-least 75% code coverage is required
6. System.debug statement are not counted as a part of apex code limit.
7. Test method and test classes are not counted as a part of code limit
9. We should not focus on the  percentage of code coverage ,we should make sure that every use case should covered including positive, negative,bulk and single record .
Single Action -To verify that the the single record produces the correct an expected result .
Bulk action -Any apex record trigger ,class or extension must be invoked for 1-200 records .
Positive behavior : Test every expected behavior occurs through every expected permutation , i,e user filled out every correctly data and not go past the limit .
Negative Testcase :-Not to add future date , Not to specify negative amount.
Restricted User :-Test whether a user with restricted access used in your code .10. Test class should be annotated with @isTest .
11 . @isTest annotation with test method  is equivalent to testMethod keyword .
12. Test method should static and no void return type .
13. Test class and method default access is private ,no matter to add access specifier .
14. classes with @isTest annotation can't be a interface or enum .
15. Test method code can't be invoked by non test request .
16. Stating with salesforce API 28.0 test method can not reside inside non test classes .
17. @Testvisible annotation to make visible private methods inside test classes.
18. Test method can not be used to test web-service call out . Please use call out mock .
19. You can't  send email from test method.
20.User, profile, organization, AsyncApexjob, Corntrigger, RecordType, ApexClass, ApexComponent ,ApexPage we can access without (seeAllData=true) .
21. SeeAllData=true will not work for API 23 version eailer .
22. Accessing static resource test records in test class e,g List<Account> accList=Test.loadData(Account,SobjectType,'ResourceName').
23. Create TestFactory class with @isTest annotation to exclude from organization code size limit .
24. @testSetup to create test records once in a method  and use in every test method in the test class .
25. We can run unit test by using Salesforce Standard UI,Force.com IDE ,Console ,API.
26. Maximum number of test classes run per 24 hour of period is  not grater of 500 or 10 multiplication of test classes of your organization.
27. As apex runs in system mode so the permission and record sharing are not taken into account . So we need to use system.runAs to enforce record sharing .
28. System.runAs will not enforce user permission or field level permission .
29. Every test to runAs count against the total number of DML issued in the process .
