System.assertEquals not working in test method

Hi,

 

I am having problems with System.assertEquals method not working in my test method. This is the trigger and the class with testmethod:-

 

 

trigger NoOfEmployeesTrigger on Account (before insert, before update) 
{
 if(Trigger.isInsert)
 {
  Account[] accs = Trigger.new;
  for(Integer i=0; i<accs.size(); i++)
  {
   if(accs[i].name.contains('19'))
   {
    accs[i].NumberOfEmployees = 25;
   }
   else
   accs[i].NumberOfEmployees = 75;
  }
 }
 
 if(Trigger.isUpdate)
 {
  Account[] accs = Trigger.new;
  for(Integer i=0; i<accs.size(); i++)
  {
   if(accs[i].name.contains('19'))
   {
    accs[i].NumberOfEmployees = 25;
   }
   else
   accs[i].NumberOfEmployees = 75;
  }
 }
}
 public class NoOfEmployeesClass
{
 static testMethod void NoOfEmployeesTest()
 {
  Account acc1 = new Account(name = 'Vim_19Jun_acc1');
  Account acc2 = new Account(name = 'Vim_20Jun_acc2');
  
  test.startTest();
  insert acc1;
  insert acc2;
 
  System.assertEquals(25, acc1.NumberOfEmployees);
  //System.assertNotEquals(acc2.NumberOfEmployees, 25);
  
  acc2.name = 'Vim_19Jun_acc2';
  update acc2;
  
  test.stopTest();
 }
}

The Number of employees field is a number field and it is giving error there under Test failures section:-

 

Method Name
Total Time (ms)
Message
Stack Trace
NoOfEmployeesClass.NoOfEmployeesTest126.0System.Exception: Assertion Failed: Expected: 25, Actual: nullClass.NoOfEmployeesClass.NoOfEmployeesTest: line 12, column 3

 

 

However, if I remove the method the test method works successfully giving 100% code coverage.

 

Please assist!

 

Thanks,

You need to re-query your account objects before you assert. The trigger updates the database record, not the 'in-memory' objects you created to do the insert. Something like:

 

Account updatedAcc1 = [select Id, NumberOfEmployees from Account where Id = :acc1.Id]

 

and then assert against updatedAcc1 should do it.

Thanks buddy!

 

It worked! (85% code coverage gained.bugging my head for where exactly can I compensate for those remaining 15%, but yes Salesforce expectation of atleast 75% is achieved happily.... :))    )

public class NoOfEmployeesClass
{
 static testMethod void NoOfEmployeesTest()
 {
  Account acc1 = new Account(name = 'Vim_19Jun_acc1');
  Account acc2 = new Account(name = 'Vim_20Jun_acc2');
  
  test.startTest();
  insert acc1;
  insert acc2;
 
  Account acc11 = [select name, id, NumberOfEmployees from Account where id = :acc1.id];
  Account acc22 = [select name, id, NumberOfEmployees from Account where id = :acc2.id];
  
  System.assertEquals(25, acc11.NumberOfEmployees);
  System.assertNotEquals(75, acc11.NumberOfEmployees);
  System.assertNotEquals(25, acc22.NumberOfEmployees);
  System.assertEquals(75, acc22.NumberOfEmployees);
  
  acc2.name = 'Vim_19Jun_acc2';
  update acc2;
  
  Account acc33 = [select name, id, NumberOfEmployees from Account where id = :acc2.id];
  System.assertEquals(25, acc33.NumberOfEmployees);
  System.assertNotEquals(75, acc33.NumberOfEmployees);
  
  test.stopTest();
  
 }
}

Glad I found this solution - working on my first Apex Trigger and Test cases and was wondering why my System.assertEquals were always failing.

 

Thanks
