This is my working code to post an happy birthday picture and message on chatter :).

Global class HappyBirthdayRandom2 implements Schedulable{
  //for test method
  public static String CRON_EXP = '0 0 0 3 9 ? 2022';
  global void execute(SchedulableContext sc) 
       // search by static resource name
       List<StaticResource> Pictures=[Select Name, ContentType, Body From StaticResource where Name like 'Filehappy%'];
       List<FeedItem> posts = new List<FeedItem>();
       List<user> lst=[Select id,name from user where date_of_birth__c =today];
          for(User u:lst)
                //generate a random number [0-5] of resource's name. 
               Integer choice=math.mod(Integer.valueof(Math.random()*100),6);

              Blob Decodedbody=Pictures[choice].body;

                FeedItem post = new FeedItem();
               post.ParentId = u.id;
                post.Type = 'ContentPost';
                // id of user that create post
                post.Body = 'Happy birthday to '+u.name+' !';
                post.ContentData = Decodedbody;
                post.ContentFileName = 'Wishes!.jpg';
             insert posts;

and the test class:

public class TestHappyBirthdayRandom {

Private Static testmethod void TestHappyBirthdayRandom (){
  HappyBirthdayRandom2  objMonthlyMail = new HappyBirthdayRandom2 ();

Profile pfl = [select id from profile where name='Standard User'];
// get today's date
date myDate = date.today();

User testUser = new User(alias = 'u1', email='u1@testorg.com',
        emailencodingkey='UTF-8', lastname='Testing', languagelocalekey='en_US',
        localesidkey='en_US', profileid = pfl.Id,  country='United States', CommunityNickname = 'u1',
        timezonesidkey='America/Los_Angeles', username='u1@testorg.com',date_of_birth__c =myDate);

                FeedItem testpost = new FeedItem();
                testpost.ParentId = null;
                testpost.Type = 'ContentPost';
                testpost.Body = 'test!';


// Schedule the test job

  String jobId = System.schedule('testBasicScheduledApex',HappyBirthdayRandom2.CRON_EXP, new HappyBirthdayRandom2());

// Get the information from the CronTrigger API object

  CronTrigger ct = [SELECT Id, CronExpression, TimesTriggered, 
     FROM CronTrigger WHERE id = :jobId];

// Verify the expressions are the same


// Verify the job has not run

  System.assertEquals(0, ct.TimesTriggered);

// Verify the next time the job will run

      System.assertEquals('2022-09-03 00:00:00', 



I am not able to run the code in the for loop of the class.

I don't understand because i have set the date of birth equal today.

Please can you help me with the test class, I'm new to the test.

Thank you

    It's not clear on what do you need help with. What lines are not covered? You can see an example for the apex scheduler here salesforce.com/us/developer/docs/apexcode/Content/… – PepeFloyd May 29 '13 at 20:40
  • Lines not covered are those after the for in the test class;i don't know how execute them.Thank you for the reply. – Enry May 30 '13 at 6:38
  • I'm not clear: what problem are you trying to solve? To just get 75-100% code coverage? Is there are an error you cannot resolve? Or just how to write a test class in general? – Mike Chale May 30 '13 at 13:56
  • I have updated my question with the error message.Please, can you take a look? – Enry May 30 '13 at 14:34

testUser is never inserted into the database, so when you write...

testpost.ParentId = testUser.id;

...this is no different than...

testpost.ParentId = null;

...and thus the corresponding error.

You shouldn't have to create the post in your test class, that defeats the purpose of the test class. Your schedulable job already does that. I believe the correct flow for your test class should be:

1) insert user with birthdate of today

2) run HappyBirthdayRandom2

3) query and assert that the happy birthday post was created.

  • I'm still not able to run the code in the for cycle of the class.I have updated the question.Thank you very much! – Enry May 30 '13 at 16:37
  • insert the test user! insert testUser; – Phil Rymek May 30 '13 at 17:21
  • 100%!you are very kind!:) – Enry May 30 '13 at 19:38

when you insert the user, make sure to have one whose birthday is today so that it'll run?

  • you are right, but it doesn't run the code after the select user again. – Enry May 30 '13 at 16:38
