Hi,

I posted this in the newbies forum too. Apologies if I have broken any protocols but I am really stumped with this and as you may imagine, when learning a new technology it is quite important that any examples work as expected.

The problem I have is that I don't know if it's something I have done or simply because the negative test cases doesn't work in the example?

First of all here is the code I'm talking about - it's in the testing section of the MileageTracker - Negative Test Case.

static testMethod void runNegativeTestCase() 
  	{
  		System.debug('Inserting 501 miles... negative test case');
  		
  		Mileage__c testMiles3 = new Mileage__c(Miles__c = 501, Date__c = System.today());
  		
  		try 
  		{
  			insert testMiles3;
  		} catch (DmlException e)
  			{
  				
				  			//Assert Error Message  
				    
				   System.assert(e.getMessage().contains('Insert failed. First exception '+
				      'on row 0; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION, '+
				      'Mileage request exceeds daily limit(500): [Miles__c]'), 
				         e.getMessage()); 
				
				//Assert Field  
				    
				   System.assertEquals(Mileage__c.Miles__c, e.getDmlFields(0)[0]);
				
				//Assert Status Code  
				    
				   System.assertEquals('FIELD_CUSTOM_VALIDATION_EXCEPTION', 
				                        e.getDmlStatusCode(0));
				        
  			}
  	}

The problem I have is that when I run the test I get the following - see linked image...

Thanks in advance for your help.

Kind regards,

Ian
