Anoop Patel 11 Controller Method Not Being Called in Test Class
My test class returns 'System.NullPointerException: Attempt to de-reference a null object' when I uncomment the highlights reference to my method? If I comment then it runs but only covers 60%.
Controller
public List<EventRelation> getParticipants(){
List<EventRelation> inviteeRelations = new List<EventRelation>();
if(mt.Id!=null){
inviteeRelations = new List<EventRelation>([SELECT Id, Relation.Name FROM EventRelation
WHERE EventId =:mt.Id
AND IsWhat = false]);
}
return inviteeRelations ;
Test Class
Test.startTest();
System.runAs(u) {
ApexPages.StandardController controller = new APexPages.StandardController(event);
CORE_viewEventWordController extension = new CORE_viewEventWordController(controller);
String url=extension.getmyimageurl();
//List<EventRelation> listPart=extension.getParticipants();
us=extension.eventOwner;
}
Test.stopTest(); }

public CORE_viewEventWordController(ApexPages.StandardController stdController) { eventId= stdController.getId(); }All Answers
public List<EventRelation> getParticipants(){
List<EventRelation> inviteeRelations = new List<EventRelation>();
if( mt != null ){ // You are usin mt.id that means if mt is null than it work like null.id
inviteeRelations = new List<EventRelation>([SELECT Id, Relation.Name FROM EventRelation
WHERE EventId =:mt.Id
AND IsWhat = false]);
}
return inviteeRelations ;
}
I hope u got the solution..
Update //List<EventRelation> listPart=extension.getParticipants(); as extension.getParticipants();
Below is updated code
Test.startTest(); System.runAs(u) { ApexPages.StandardController controller = new APexPages.StandardController(event); CORE_viewEventWordController extension = new CORE_viewEventWordController(controller); String url=extension.getmyimageurl(); extension.getParticipants(); us=extension.eventOwner; } Test.stopTest(); }Best Regards,

Without seeing the rest of your controller, it appears the "mt" variable in your method is what is causing the NullPointerException. Make sure that mt is populated. Furthermore, your method queries for the EventRelation object. You'll need to create all of these records in your unit tests before you execute the code, in order for your test to succeed.
public class CORE_viewEventWordController {
public Event mt{
get{
if(mt==null && eventId!=null)
{
try{
mt=[Select id,OwnerId,WhatId,ActivityDate,ActivityDateTime,Subject,Description,Location,Summary__c From Event WHERE IsDeleted = false AND id=:eventId LIMIT 1 ALL ROWS];
}catch(Exception e){}
}
return mt;
}
set;
}
public User eventOwner{
get{
if(eventOwner==null && mt!=null && mt.OwnerId!=null )
{
try{
eventOwner=[Select id,Name From User where id=:mt.OwnerId LIMIT 1];
}catch(Exception e){}
}
return eventOwner;
}
set;
}
Id eventId;
public CORE_viewEventWordController(ApexPages.StandardController stdController) {
eventId=(Id)System.currentPageReference().getParameters().get('id');
//((Event)stdController.getRecord()).id;
}
public String getmyimageurl () {
string imageid='';
try{
Document dc = [Select id from Document where Name = 'LCHLogo' LIMIT 1];
imageid = String.valueof(dc.id).substring(0,15);
}catch(Exception e){}
String orgId = UserInfo.getOrganizationId();
String domain= ApexPages.currentPage().getHeaders().get('Host') ;
return 'http://'+domain+'/servlet/servlet.ImageServer?id='+imageid +'&oid='+orgId;
}
public List<EventRelation> getParticipants(){
List<EventRelation> inviteeRelations = new List<EventRelation>();
if(mt.Id!=null){
inviteeRelations = new List<EventRelation>([SELECT Id, Relation.Name FROM EventRelation
WHERE EventId =:mt.Id
AND IsWhat = false]);
}
return inviteeRelations ;
}
}
This is complete test;
@isTest
private class CORE_viewEventWordControllerTest {
static User u;
static Contact contact;
static Account acc;
static{
// create a user to run the test as
Profile p = [select id from profile where name='System Administrator'];
u = new User(alias = 'test456', email='test456@noemail.com',
emailencodingkey='UTF-8', lastname='Testing2', languagelocalekey='en_US',
localesidkey='en_US', profileid = p.Id, country='United States',
timezonesidkey='America/Los_Angeles', username='test456@noemail.com');
insert u;
contact = new Contact(Phone='+34987888888',LastName='lastnametest');
acc= new Account(Name='TestAcc');
}
@isTest (SeeAllData=true) static void findsDocument() {
performTest();
}
@isTest static void doesNoTFindDocument() {
performTest();
}
static void performTest(){
User us;
System.runAs(u) {
insert contact;
insert acc;
}
Event event=new Event(DurationInMinutes=10,ActivityDateTime=datetime.now(),WhoId=contact.id,whatId=acc.id);
System.runAs(u) {
insert event;
}
Test.startTest();
System.runAs(u) {
ApexPages.StandardController controller = new APexPages.StandardController(event);
CORE_viewEventWordController extension = new CORE_viewEventWordController(controller);
String url=extension.getmyimageurl();
//List<EventRelation> listPart=extension.getParticipants();
us=extension.eventOwner;
}
Test.stopTest(); }
}
Your test is looking for an http parameter of "id". Either you need to specify this http parameter in your test class, or you need to upate your constructor to look for the id using the standard controller like so:
Also, personally, I hate the getters where you check if it doesn't exist, then you fetch it. This is typically only relevant in a singleton pattern. Why not simply query for the object or initialize it in your constructor?
String url=extension.getmyimageurl();
and should it look like this;
eventId = stdController.getId();
public CORE_viewEventWordController(ApexPages.StandardController stdController) { eventId= stdController.getId(); }Once I changed this in my controller it worked and came back with 93% coverage.
Thanks again.
