i am not using any DML statement after doApiCall function as you can see . but why i am facing trhis error ??Please guideline to resolve it.

riggeri am testing a trigger.i am calling this method

but when i initialize prepare String body='{"html":"'+type+':'+ '"'+obj.getSObject('CreatedBy')+' '+obj.getSObject('CreatedBy')+'

'+obj.get(contentMap.get('Content'))+'

'+ ' "}'; i check it in debug logs its giving me null for getSObject('CreatedBy'); i inserted it in my test class thats why trigger invoked and i am using afterinsert event in trigger . can any one please tell why its giving me null ??

i am trying to test a trigger my trigger code is 

trigger PostFeedsToTimeLine on FeedItem (after insert) {
Map<String,String> contentMap = new Map<String,String>{'Object' =>'FeedItem','Content' =>'Body'};
if(Trigger.new.size() > 5){
BatchPublishTimeLine publishBatch = new BatchPublishTimeLine(Trigger.new,contentMap);
Database.executeBatch(publishBatch,5);
}
else GMirrorUtil.createTimeLine(Trigger.new, contentMap);
}

batch will always get created if size is greater than 5 but when size is greater than 5 two batch will get executed  what to do.in batch i am calling GMirrorUtil.createTimeLine which is making two callouts thats why this 5 limit .what to do in this case ?? because maximum 5 batch can be queued thats why if possible i try to make it without batch but in cases when more than 5 then i execute it using Batch.

My Test function is 

@isTest(SeeAllData=true)
static void test1(){
MirrorTestUtil.setupSettings();
User u = [Select Authorize__c From User Where Id = :UserInfo.getUserId()];
u.Authorize__c = true;
update u;
List<FeedItem> feedList= new List<FeedItem>();
for (Integer i = 0; i<10;i++)
feedList.add( new FeedItem(Body='Hello World'+i,ParentId = UserInfo.getUserId()));
Test.startTest();
insert feedList;
Test.stopTest();
}

as u can see i updated User Authorize__c = true;

from this a trigger get called after that because its bulk that why i am doing my operation as Batch apex .code for that is here 

public class PublishGlassTimeLine implements Database.Batchable<sObject>{
SObjectIterable iterable;
Map<Id,User> userMap;
Map<Id,GlassUserApiSettings__c> userSettingsMap;
Map <String,String> contentmap;

public PublishGlassTimeLine(List<sObject>objectList,Map<String,String> contentmap){
iterable = new sObjectIterable(objectList);
this.userMap = new Map<Id,User>([Select Id,Name From User WHERE Authorize__c = true]);
userSettingsMap = new Map<Id,GlassUserApiSettings__c>();
System.debug('user map is '+userMap);
System.debug('user map values are '+userMap.Values());
for(User user: userMap.Values())
userSettingsMap.put(user.Id,GlassUserApiSettings__c.getValues(user.Id));
this.contentmap = contentmap;
}

public Iterable<sObject> start(Database.BatchableContext BC){
return iterable;
}

public void execute(Database.BatchableContext BC, List<sObject> scope){
GMirrorUtil.createTimeLine(scope, contentMap);
}

public void finish(Database.BatchableContext BC){
System.debug('Job Has been Finished');
}
}

its giving me error

System.DmlException: Insert failed. First exception on row 0; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, PostFeedsToTimeLine: execution of AfterInsert

caused by: System.NullPointerException: Attempt to de-reference a null object

Class.BatchPublishTimeLine.<init>: line 11, column 1
Trigger.PostFeedsToTimeLine: line 4, column 1: []

he is referring null object to userMap.

but i think it should not be null.

can any one please tell why i am facing this NullPointer exception ??

i have a custom setting that is Public and have to test for DMLException.i am doing one thing creating and inserting as one usere and calling the delete method as secong user which will not have access to This custom settings.i want to know is custom settings available for all profiles because its not throwing any exception my Apex function is 

  public PageReference deleteUserSettings(){

       try{        delete userSettings;       

  userSettings = new GlassUserApiSettings__c(setUpOwnerId = UserInfo.getUserId());

             }   

   catch (System.DMLException e){System.debug(e);} 

      return null;    }

and my test code is

@isTest(SeeAllData=true)
static void testDeleteApiSettingsN(){
MirrorTestUtil.setupSettings();

Profile p = [SELECT Id FROM Profile WHERE Name='Read Only'];
User u2 = new User(Alias = 'newUser', Email='newuser@testorg.com',
EmailEncodingKey='UTF-8', LastName='Testing', LanguageLocaleKey='en_US',
LocaleSidKey='en_US', ProfileId = p.Id,
TimeZoneSidKey='America/Los_Angeles', UserName='standarduser@orgtest.com');
MirrorSettingsController ctrl = new MirrorSettingsController();
System.runAs(u2) {
Test.startTest();
ctrl.deleteUserSettings();
Test.stopTest();
}
}

i tried it with Stasndard User as well but its deleting not throwing exception. can any one please tell how to make code coverage of this to DMLException .

i am trying to test my Controller .One doubt is in using Test.startTet and Test.stopTest().i am checking every method in separate unit test . for example

static testmethod void testEditApiSettings(){
         MirrorTestUtility.getApiSettings();
    Test.startTest();
    MirrorSettingsController ctrl = new MirrorSettingsController();   
  ctrl.setEditApiSettings();
  Test.stopTest();
System.assert(ctrl.editApiSettings,'Method perform to Show Insert view# Not able to set ');
}
static testmethod void testDeleteApiSettings(){
MirrorTestUtility.setUpSettings();
Test.startTest();
MirrorSettingsController ctrl = new MirrorSettingsController();
ctrl.deleteUserSettings();
Test.stopTest();
 GlassUserApiSettings__c userSettings =  GlassUserApiSettings__c.getValues(UserInfo.getUserId());
System.assert(userSettings== null ,'User settings are present ence Method don\'t delete Usetr Settings' );
}

so you can see i create ctrl every time in test.startTest() is this more appropriate or creating it before Test.startTest();

1. there is a DML exception perhaps that cant come because DML limit is 100 and i am hardly using 2-3 in my controller. i write a function

   public PageReference deleteUserSettings(){
   try{  
   delete userSettings;  
   userSettings = GlassUserApiSettings__c.getValues(Userinfo.getUserId());
   }
   catch(System.DmlException e){System.debug(e); }
   return null;
    }

   how to test this should i remove this try catch block (because exception is not expected)??How to test this catch block please guideline .

i want to create a custom exception. In this Exception i want to make a constructor which take one string arguments and append in getMessage .How to accomplish this.

 public class TimelineException extends Exception{

    }
  }

main problem i am facing is when i use this public TimelineException(Sting x){ } then its give me error

Save error: System exception constructor already defined: (String) GMirror.cls /Google Salesforce Integration/src/classes.

i am trying to understand OR ,AND and NOT operator in rendered attribute.itried some but not successful. for example

tried one  experiment

hi i am sending only a single Http Request in Batch but still facing error System.CalloutException: You have uncommitted work pending. Please commit or rollback before calling out

My test code is 

@isTest(SeeAllData=true)
static void test1(){
MirrorTestUtil.setupSettings();
User u = [Select Authorize__c From User Where Id = :UserInfo.getUserId()];
u.Authorize__c = true;
update u;
System.debug('u is '+u);

List<FeedItem> feedList= new List<FeedItem>();
for (Integer i = 0; i<5;i++)
feedList.add( new FeedItem(Body='@'+UserInfo.getName()+'Hello World'+i,ParentId = UserInfo.getUserId()));
Test.setMock(HttpCalloutMock.class, new MirrorMockTimelinePostImpl());
Test.startTest();
Test.setMock(HttpCalloutMock.class, new MirrorMockTimelinePostImpl());

insert feedList;
Test.stopTest();
}

and My trigger code is 

trigger PostFeedsToTimeLine on FeedItem (after insert) {

BatchPublishTimeLine publishBatch = new BatchPublishTimeLine(Trigger.new,contentMap);
Database.executeBatch(publishBatch,5);
}

and My Batch class code is 

public class BatchPublishTimeLine implements Database.Batchable<sObject>{
sObjectIterable iterable;
Map<Id,User> userMap;
Map<String,String> contentmap;

public BatchPublishTimeLine(List<sObject> objectList,Map<String,String> contentmap){
iterable = new sObjectIterable(objectList);
this.userMap = new Map<Id,User>([Select Id,Name From User WHERE Authorize__c = true]);
this.contentmap = contentmap;
}

public Iterable<sObject> start(Database.BatchableContext BC){
return iterable;
}

public void execute(Database.BatchableContext BC, List<sObject> scope){
GMirrorUtil.createTimeLine(scope, contentMap);
}

public void finish(Database.BatchableContext BC){
System.debug('Job Has been Finished');
}
}

and My createTimeLine function code is 

public static void createTimeLine(List<sObject> objList,Map<String,String> contentMap){

String timelineRes = doApiCall('xyzzz','POST','https://www.googleapis.com/mirror/v1/timeline','xxxxxxxxx');

}

doApiCall code is 

public static String doAPICall(String postBody, String method, String endPoint, String accessToken){

HttpRequest req = new HttpRequest();
Http http = new Http();
HttpResponse res;

req.setEndpoint(endPoint);
req.setMethod(method);
req.setHeader('Content-Type','application/json');

if(method == 'POST' || method == 'PUT')
req.setBody(postBody);
req.setHeader('Authorization','Bearer ' + accessToken);
res = http.send(req);
String result = res.getBody();
System.debug('status code is '+res.getStatus());
System.debug('result is'+res.getBody());
return result;
}

and the Mock class code response is 

@isTest
global class MirrorMockTimelinePostImpl implements HTTPCalloutMock {
global HTTPResponse respond(HTTPRequest req) {
// Optionally, only send a mock response for a specific endpoint
// and method.
System.assertEquals('https://www.googleapis.com/mirror/v1/timeline', req.getEndpoint());
System.assertEquals('POST', req.getMethod());
System.assert(req.getHeader('Authorization').startsWith('Bearer'));

// Create a fake response
HttpResponse res = new HttpResponse();
res.setHeader('Content-Type', 'application/json');
res.setBody('{"kind":"mirror#timelineItem", "id":"mockid", "created":"2013-07-31T12:07:34.882Z", "updated":"2013-07-31T12:07:34.882Z", "etag":"\\"ZECOuWdXUAqVdpmYErDm2-91GmY/NVMWuR8LJyCKttsmne9R4K8n7YI\\"", "text": "New Lead: OauthCheck EarlyAm, Google, Inc., (234) 567-8900"}');
