[SalesForce] Webservice callout – Test class – not working

I have batch class that makes a HTTP callout to a remote web service. To deploy into production, I have created a test class with StaticResourceCalloutMock.

I am executing the test class in a full copy sandbox and it is working fine. But when I deploy, it is failing. Not sure what is going on.

Getting the following error message

System.NullPointerException: Attempt to de-reference a null object
Stack Trace: Class.InsideviewPostJob.IVPostRequest: line 26, column 1
Class.AccountAPIToInsideviewRequest.Execute: line 37, column 1

Deployment is failing at the following line in the class – InsideviewPostJob

if (res.getStatus()=='OK' && res.getstatuscode()==200) {

Test Class:

        test.startTest();
         StaticResourceCalloutMock Mock = new StaticResourceCalloutMock();
         mock.setStaticResource('AccountPostJobResp');
         mock.setstatusCode(200);
         mock.setStatus('OK');
         mock.setHeader('Accept', 'application/json');
         mock.setHeader('Content-Type', 'text/plain');
         test.setMock(HttpCalloutMock.class, Mock);
         AccountAPIToInsideviewRequest  ivapi = new  AccountAPIToInsideviewRequest();
         Database.executeBatch(ivapi, 1);

         /* ivTokenUtil test class execution*/  
         test.stopTest();

Batch Class:

Global void Execute(Database.BatchableContext BC, List<sObject> scope)
{

    system.debug('Hello Execute');

    String CompanyIDs = '';

    List<String> ProcessedCIs = new List<String>();

    for (Sobject s : Scope)
    {        
     Account Act = (Account)s;
   /*  system.debug('Hello Execute and account:' + Act.NAME);*/

     CompanyIds += Act.Insideview_ID__c + ',' ;
     ProcessedCIs.add(Act.Insideview_ID__c);

    } 

    CompanyIds = CompanyIds.substring(0, CompanyIds.length() -1);          
    String EndpointURL = 'https://api.insideview.com/api/v1/company/job';
    string ivjobid = InsideviewPostJob.IVPostRequest(EndpointURL, CompanyIds);

Webservice Callout Class

Global class InsideviewPostJob{

    public static string IVPostRequest(String EndpointURL, String InsideViewIds) {
        String InsideviewJobId;
        System.debug('InsideViewIds: '+ InsideViewIds);
        if (InsideViewIds==null || InsideViewIds=='') {
            System.debug('No CompanyIds to send to Insideview API');
            return InsideviewJobId;
        }
        HttpRequest req = new HttpRequest();
        req.setEndpoint(EndpointURL);
        req.setMethod('POST');
        req.setHeader('accessToken', IVTokenUtils.getToken());
        req.setHeader('Accept', 'application/json');
        req.setheader('Content-Type', 'text/plain');
        req.setBody(InsideViewIds);
        system.debug('req.getBody():' + req.getBody());
        Http http = new Http();
        HttpResponse res = null;
        try {
            res = http.send(req);
        } catch(System.CalloutException e) {
            System.debug('Callout error: '+ e);
        }
        system.debug('PostJob-Resp: ' + res);
        if (res.getStatus()=='OK' && res.getstatuscode()==200) {
            String jsonData = res.getBody();
            System.debug('Post Response: '+ jsonData);
            InsideViewPostResp postResp = (InsideViewPostResp)JSON.deserialize(jsonData, InsideViewPostResp.class);

            if (postResp.jobId!=null) {
                InsideviewJobId = postResp.jobId;
            }
            return InsideviewJobId;
        }
       return InsideviewJobId;
    }
    }

Additional comment
In above case, batchclass calls the future method and future method call the webservice class.

if I directly call the InsideviewPostJob from the test class, deployment works fine.

look at below test class that directly calls the webservice callout class.

@istest(seealldata=true)
public class InsideViewPostJob_Test {
    static testmethod void InsideViewPostJobTest(){


         //Create User
        User Usr = new User();
        Usr.Username = 'testxxx@inventivhealth.com';
        Usr.LastName = 'x'; 
        Usr.Email = 'testxxx@inventivhealth.com'; 
        Usr.Alias = 'testxxx'; 
        Usr.CommunityNickname = 'testxxxx';
        Usr.TimeZoneSidKey = 'America/New_York'; 
        Usr.LocaleSidKey = 'en_US'; 
        Usr.EmailEncodingKey = 'ISO-8859-1'; 
        Usr.ProfileId = ([select Id from Profile where name = 'iVH System Administrator'])[0].id;
        Usr.LanguageLocaleKey = 'en_us';
        Usr.iVH_Business_Unit__c = 'Adheris Health';
        insert usr; 

     system.runas(usr){
            test.startTest();
                StaticResourceCalloutMock Mock = new StaticResourceCalloutMock();
                mock.setStaticResource('PostJobResp');
                mock.setstatusCode(200);
                mock.setStatus('OK');
                mock.setHeader('Accept', 'application/json');
                test.setMock(HttpCalloutMock.class, Mock);
                string ivCompanyID = '12345';
                string EndpointURL = 'https://api.insideview.com/api/v1/company/job';     
                InsideviewPostJob.IVPostRequest(EndpointURL, ivCompanyID);
                InsideViewPostResp postResp = new InsideViewPostResp();
            test.stopTest();    
        } 

    }   

}

Salesforcemarty,MkeKatulla,

Thanks for the response for my query. Your counter questions helped me in my analysis.

Finally it worked.

Here is the answer. In Fullcopy, webservice callout from schedulable/batch class works when you unit test (test class), if your try to deploy the same testclass fails.

Earlier code: in test class seealldata = false. few insert/update before test.startTest(). Between starttest() and stoptest(), I have put StaticResourceCalloutMock and called the batch class. It was giving error 'Pending work' during deployment. It works in fullcopy.

Working code in Test class seealldata = true. removed all insert/update before starttest() kept the code between starttest() and stoptest() as it is..

Now deployment works..

My understanding on having DML operation before starttest() was WRONG.
