How do I test for an exception('addError') in a class?

Hi everyone,

I have to test this class:

List<Account> oldAccounts   = Trigger.old;
        for(Account check : oldAccounts){
            if(check.Account_ID__c!=null){
                check.addError('Accounts that have SAP Account ID can not be deleted');
            }
        }

I know that in theese cases one has to use try/catch methods to solve the test.
But I've been trying for hours and I don't know how to solve it.

I post what I did so far, it covers everything except last line ('addError'):

@isTest
public class TriggerAccountDeleteTest {
      public class MyException extends Exception {}
       static testMethod void metodoDeletAccount(){
        
             //Create an Account with his required fields
             Account accountPrueba = new Account();
                accountPrueba.Name = 'Siemens2';
                accountPrueba.Account_Country__c = 'a014E000005XNKh';
                accountPrueba.Language__c = 'a064E0000060Wnr'; 
                accountPrueba.Department__c = 'Services';
            
            //Insert it
            insert accountPrueba ;
           
            //Test.startTest();  
                try{
                    delete accountPrueba;
                    Account deletedAccount = [SELECT Id, IsDeleted FROM Account WHERE Id = :accountPrueba.Id ALL ROWS];
                    System.assertEquals(deletedAccount.IsDeleted, true);
        
                    }
                 catch(Exception e){
                    Boolean b = null;
                    accountPrueba2.Account_ID__c = String.valueOf(b);
                    System.assert(e.getMessage().contains('Accounts that have SAP Account ID can not be deleted'));
                 }
               Test.stopTest();   
        
    }
}
Thank you for your time
Cheers,
Alberto

Please below test class
@isTest
public class TriggerAccountDeleteTest 
{
	static testMethod void metodoDeletAccount()
	{
	
		 Account accountPrueba = new Account();
			accountPrueba.Name = 'Siemens2';
			accountPrueba.Account_Country__c = 'a014E000005XNKh';
			accountPrueba.Language__c = 'a064E0000060Wnr'; 
			accountPrueba.Department__c = 'Services';
			accountPrueba.Account_ID__c ='ID111';
		insert accountPrueba ;
	   
		Test.startTest();  
			try
			{
				delete accountPrueba;       
			}
			catch(Exception e)
			{
				Boolean expectedExceptionThrown =  e.getMessage().contains('Accounts that have SAP Account ID can not be deleted')) ? true : false;
				System.AssertEquals(expectedExceptionThrown, true);                
			}
		Test.stopTest();   
	
	}
}

Hi Alberto,

Change the test class code like this:
@isTest
public class TriggerAccountDeleteTest {
      public class MyException extends Exception {}
       static testMethod void metodoDeletAccount(){
        
             //Create an Account with his required fields
             Account accountPrueba = new Account();
                accountPrueba.Name = 'Siemens2';
                accountPrueba.Account_Country__c = 'a014E000005XNKh';
                accountPrueba.Language__c = 'a064E0000060Wnr'; 
                accountPrueba.Department__c = 'Services';
            
            //Insert it
            insert accountPrueba ;
    //insert accountPrueba2 here, by assigning some value to Account_ID__c -- update
           

              Test.startTest();  
                try{
                    delete accountPrueba;
                    Account deletedAccount = [SELECT Id, IsDeleted FROM Account WHERE Id = :accountPrueba.Id ALL ROWS];
                    System.assertEquals(deletedAccount.IsDeleted, true);
                    delete accountPrueba2;
                    }
                 catch(Exception e){
                    //Boolean b = null;
                    //accountPrueba2.Account_ID__c = String.valueOf(b);
                    System.assert(e.getMessage().contains('Accounts that have SAP Account ID can not be deleted'));
                 }
               Test.stopTest();   
        
    }
}

Please mark this as the solution, if it solves your problem.
