Trailhead: Coverage 100% but challenge failed

I have this very simple class..  
trigger RestrictContactByName on Contact (before insert, before update) {
    //check contacts prior to insert or update for invalid data
    For (Contact c : Trigger.New) {
        if(c.LastName == 'INVALIDNAME') {   //invalidname is invalid
            c.AddError('The Last Name "'+c.LastName+'" is not allowed for DML');
        }
    }
}
.. and the corresponding Test Class:  
@isTest
private class TestRestrictContactByName {

	@isTest static void metodoTest() {
		
		List listaContatti = new List();
		Contact c1 = new Contact(FirstName='Francesco', LastName='Riggio');
		Contact c2 = new Contact(LastName = 'INVALIDNAME');
		listaContatti.add(c1);
		listaContatti.add(c2);
		
		//insert listaContatti;
		
		// Perform test
        Test.startTest();
        Database.SaveResult [] result = Database.insert(listaContatti, false);
        Test.stopTest(); 
		
		c1.LastName = 'INVALIDNAME';
		update c1;
       		
	}
	
}

When I run the Test class from the Developer Console I get 100% of coverage on the RestrictContactByName class but, when I check the challenge on the trailhead it returns the error:

Challenge not yet complete... here's what's wrong: The 'RestrictContactByName' class did not achieve 100% code coverage via your test methods

Has someone had my same issue?

HI Andrea Ianni,

Please try below Test Class :-
@isTest
private class TestRestrictContactByName {

    static testMethod void  metodoTest() 
    {
    
        List<Contact> listContact= new List<Contact>();
        Contact c1 = new Contact(FirstName='Francesco', LastName='Riggio' , email='Test@test.com');
        Contact c2 = new Contact(FirstName='Francesco1', LastName = 'INVALIDNAME',email='Test@test.com');
        listContact.add(c1);
        listContact.add(c2);
        
        Test.startTest();
            try
            {
                insert listContact;
            }
            catch(Exception ee)
            {
            }
        
        Test.stopTest(); 
        
    }
    
}

With Above test class i got all 500 Point.

It doesn't work. I thought it was because I didn't considered the "before update" of the trigger. So I modified the code:
@isTest
private class TestRestrictContactByName {

	@isTest static void metodoTest() {
		
		List listaContatti = new List();
		Contact c1 = new Contact(FirstName='Francesco', LastName='Riggio' , email='Testfr@test.com');
		Contact c2 = new Contact(FirstName='Andrea', LastName = 'INVALIDNAME', email='Testam@test.com');
		listaContatti.add(c1);
		listaContatti.add(c2);
		
        //Test.startTest();
			try{
				insert listaContatti;
			} catch(Exception ee){
			
            }
		
        //Test.stopTest(); 
		
       		
	}
	
    
	@isTest static void metodoTest2() {
		
		List listaContatti = new List();
		Contact c1 = new Contact(FirstName='Stefano', LastName='Massoni' , email='Testm@test.com');
		Contact c2 = new Contact(FirstName='Simone', LastName = 'Coman',email='Testb@test.com');
		listaContatti.add(c1);
		listaContatti.add(c2);
		
        //Test.startTest();
			try{
				insert listaContatti;
			} catch(Exception ee){
                
			}
			
        	listaContatti.get(0).LastName = 'INVALIDNAME';
        
        	try{
            	update listaContatti;
            } catch(Exception ee){
                
            }
        
        //Test.stopTest(); 
		
       		
	}    
}

.... but, it doesn't "cover" the class to 100%.

Ehi Amit,

I tried to see if I had Validation Rules but I didn't. I tried all the possible issues.

At the end I connected another ORG to my trailhead and... I passed the challenge!
I'm sorry I didn't understand why I couldn't pass it but... at least the code is right! Thank you for your time!

I have the same issue with this challenge.  I have a test class which provides 100% test coverage from both the developer console and the standard setup UI.  But the challenge says "Challenge not yet complete... here's what's wrong: The 'RestrictContactByName' class did not achieve 100% code coverage via your test methods".  The challenge is broken in my view.
Richard Clarke - Artisan ConsultingRichard Clarke - Artisan Consulting
And just a follow-up - like others in this discussion I pasted the exact same code into another DE and that worked fine
Ari Weitzman 8Ari Weitzman 8
Same issue with me and a few others who are also taking this trailhead; our solution was to run the tests from the UI instead of the console, and for whatever reason that satisfied the code coverage demons.

Principles of Testing.

Hi Andrea, thanks for posing the question!
Hi Amit, thanks for writing a solution!

It is true that Amit's solution passes the Trailhead test, in this case because running his test gives 100% code coverage.  However, his test code itself is not actually a test written in the sense of a unit test (please take this as constructive, Amit!).  A good way to think of unit testing is with the three A's: Arrange, Act, Assert.  We first set up the test (Arrange), then we carry out the calculations (Act), then we check if what we expected to happen really happened (Assert).  If you would like to know more about unit testing, look up books by Robert Martin (Uncle Bob) or Kent Beck or search for the test "test-driven development".

Below I've given an example of a unit test to solve this trailhead challenge.  In general, I don't think it's necessarily good to write whole solutions in the discussion forums (because people can then copy and paste without understanding), but I think in this case it's passable because unit testing is such an important concept in modern software development.  You will see that the inputs for the tests are first arranged (Arrange), then the calculations are carried out (Act), then we check if we got what we expected ((Assert) . If you look in the Class that you are testing, you should be able to work out what you are testing and what you expect to get.  Ideally, for a full test solution, you should also write a second test for the case when the LastName is not invalid.

Happy Testing!

David.

        Contact newContact = new Contact(LastName= inputLastName);

        Test.startTest();
        try{
            insert newContact;
        }
        catch (DmlException dmlEx) {
        	
        	// Verify (Assert)
        	// In this case the insert should have been stopped by the trigger,
        	// so we need to verify that we got a dml exception (and specifically that we got the error message
            // that we were expecting).
        	String expectedMessage = 'The Last Name "'+ newContact.LastName+'" is not allowed for DML';

Hi - if anyone was following what David wrote above but was getting the "Challenge not yet complete... here's what's wrong: The 'RestrictContactByName' class did not achieve 100% code coverage via your test methods" error anyway, it's because he only tested for the trigger failing where for full code coverage the test needed to succeed too.

This is easily fixed by adding
Contact newContact2 = new Contact(LastName= 'Smith');
at the 9th line, and 
insert newContact2;
under the 13th line of his code. Essentially just making sure the test spits out at least one 'fail' and one 'pass'.

How can resolve this issue : my code coverage is 100% and challenge is completed but the method in Test class is Failed for below challenge:

Install a simple Apex trigger, write unit tests that achieves 100% code coverage for the trigger, and run your Apex tests.The Apex trigger to test is called 'RestrictContactByName', and the code is available here. Copy and paste this trigger into your Developer Edition via the Developer Console.
'RestrictContactByName' is a trigger which blocks inserts and updates to any contact with a last name of 'INVALIDNAME'.
The unit tests must be in a separate Apex class called 'TestRestrictContactByName'.
The unit tests must cover scenarios for all lines of code included in the Apex trigger, resulting in 100% code coverage.
Run your test class at least once (via 'Run All' tests the Developer Console) before attempting to verify this challenge.


My TestClass code:

@isTest
public class TestRestrictContactByName {
    
    @isTest static void TestInUpRestrictContactByName()
    {
        contact cont=new contact(LastName='INVALIDNAME');
        upsert cont;
    
    Test.startTest();
    Database.UpsertResult result=Database.upsert(cont,false);
    Test.stopTest();
    
    System.assert(!result.isSuccess());
        System.assert(result.getErrors().size() > 0);
        System.assertEquals('Cannot insert or update a record with INVALIDNAME as lastname',
                             result.getErrors()[0].getMessage());
    }
}



can anyone help me....??? guys

Just Try the below test class. It is giving 100% coverage as well challenge completed status.
@isTest
private class TestRestrictContactByName {
    @isTest static void test1(){
        contact c = new Contact();
        c.LastName = 'INVALIDNAME';
        // Perform test
        Test.startTest();
        insert c;
        Test.stopTest();
    }
     @isTest static void test2(){
        contact c = new Contact();
        c.LastName = 'Devi';
        // Perform test
        Test.startTest();
        insert c;
        Test.stopTest();
    }
    
}

Try this one:

@isTest

	@isTest static void testInsertInvalidName(){
        //Test Data Setup
        Contact tstContact = new Contact(LastName = 'INVALIDNAME');
        upsert tstContact;
        
        //Perform Test
        Test.startTest();
        Database.UpsertResult result = Database.upsert(tstContact, false);
        Test.stopTest();
        
        //Verify
		System.assert(!result.isSuccess());
        System.assert(result.getErrors().size() > 0);
        System.assertEquals('The Last Name "INVALIDNAME" is not allowed for DML',

try this one after try all above did this because question is for update and insert so it goes for upsert !! sucess
 
dMaxSfDevdMaxSfDev
This works and gives 100% coverage, but this only tests the negative test case. Also, you might want to check if your assert statement has "INVALIDNAME" within double quotes. 

@isTest
public class TestRestrictContactByName {
    
        @isTest static void TestInsertContactWithInvalidLastName() {
        // Test data setup
        // Create a contact with the last name INVALIDNAME
        Contact cont = new Contact(FirstName = 'John ', LastName = 'INVALIDNAME');
            
        // Perform test
        Test.startTest();
        Database.SaveResult result = Database.insert(cont, false);
        Test.stopTest();

        // Verify 
        // In this case the insert operation should have been stopped by the trigger,
        // so verify that we got back an error.
        System.assert(!result.isSuccess());
        System.assert(result.getErrors().size() > 0);
        System.assertEquals('The Last Name "INVALIDNAME" is not allowed for DML',
                             result.getErrors()[0].getMessage());
    
        }

}

public class TestRestrictContactByName {
    
    @isTest static void testInvalidName(){
        
        List<contact> con=new List<Contact>();
        Contact c1=new Contact(LastName='@@');
        Contact c2=new Contact(LastName='Mahi');
        Contact c3=new Contact(LastName='INVALIDNAME');
        con.add(c1);
        con.add(c2);
        con.add(c3);
       
        Test.startTest();
        try{
            insert con;
        }
        
        catch(DMLException de){
            string Expectedmessage1 = 'the last name "'+c1.lastname+' "is not allowed for DML';
            string Expectedmessage3 = 'the last name "'+c3.lastname+' "is not allowed for DML';
            system.assertEquals(Expectedmessage1, de.getDMLMessage(0));
            system.assertEquals(Expectedmessage3, de.getDMLMessage(0));
        }
        Test.stopTest();
    }

Here u can simply...

private class TestRestrictContactByName 
{
    @isTest static void testInsert()
    {
        Contact d=new Contact(LastName='INVALIDNAME', FirstName='Error');
        Test.startTest();
        try{
            insert d;     
        }
        catch(Exception e) { }
        Test.stopTest();
    }
}

I am surprised how much bad practices are suggested as "Correct" answer!

While most of the suggested test classes will let you achieve 100% code coverage and pass the module; the suggested code will not test the DML: this is worse than no code coverage!

Example of bad code:
try{
            insert d;     
        }
        catch(Exception e) { }
Why:
1) this returns nothin to validate;
2) checks only 'insert' operation. The test must validate both insert and update operations. You can't use 'upsert' because such record should not exist in your instance and test code will always go to "insert" branch of the method.
3) The test must check the actual parameters returns; I believe checking success or failure is enough:
System.assert(!result.isSuccess());
OR
System.assert(result.isSuccess());

 
Amit Chaudhary 8Amit Chaudhary 8
Yes. We should add assert in tes class like below
@isTest
private class TestRestrictContactByName
{
	static testMethod void contactInsertSuccess()
	{
		Boolean insertFailed = false;
		Contact con=new Contact(FirstName='ABC', LastName='Mahi');
		try{
			Test.startTest();
				insert con;
			Test.stopTest();
		}catch(Exception e){
			insertFailed = true;
		}
		System.assertEquals(false,insertFailed);
	}
	static testMethod void contactInsertFail()
	{
		Boolean insertFailed;
		Contact con=new Contact(FirstName='ABC', LastName='INVALIDNAME');
		try{
			Test.startTest();
				insert con;
			Test.stopTest();
		}catch(Exception e){
			insertFailed = true;
		}
		System.assertEquals(true,insertFailed);
	}
}

Or we can assert the size of like below
@isTest
private class TestRestrictContactByName {

    @isTest static void metodoTest() 
    {
        Contact c = new Contact(LastName = 'INVALIDNAME');
        Database.SaveResult result = Database.insert(c, false);
       
        System.assert(!result.isSuccess());
        System.assert(result.getErrors().size() > 0);
        System.assertEquals('The Last Name "INVALIDNAME" is not allowed for DML',
                             result.getErrors()[0].getMessage());


        
    }
    
}




And we should also follow below best pratice in test class

Please follow below salesforce Best Practice for Test Classes :-

1. Test class must start with @isTest annotation if class class version is more than 25
2. Test environment support @testVisible , @testSetUp as well
3. Unit test is to test particular piece of code working properly or not .
4. Unit test method takes no argument ,commit no data to database ,send no email ,flagged with testMethod keyword .
5. To deploy to production at-least 75% code coverage is required
6. System.debug statement are not counted as a part of apex code limit.
7. Test method and test classes are not counted as a part of code limit
9. We should not focus on the  percentage of code coverage ,we should make sure that every use case should covered including positive, negative,bulk and single record .
Single Action -To verify that the the single record produces the correct an expected result .
Bulk action -Any apex record trigger ,class or extension must be invoked for 1-200 records .
Positive behavior : Test every expected behavior occurs through every expected permutation , i,e user filled out every correctly data and not go past the limit .
Negative Testcase :-Not to add future date , Not to specify negative amount.
Restricted User :-Test whether a user with restricted access used in your code .
10. Test class should be annotated with @isTest .
11 . @isTest annotation with test method  is equivalent to testMethod keyword .
12. Test method should static and no void return type .
13. Test class and method default access is private ,no matter to add access specifier .
14. classes with @isTest annotation can't be a interface or enum .
15. Test method code can't be invoked by non test request .
16. Stating with salesforce API 28.0 test method can not reside inside non test classes .
17. @Testvisible annotation to make visible private methods inside test classes.
18. Test method can not be used to test web-service call out . Please use call out mock .
19. You can't  send email from test method.
20.User, profile, organization, AsyncApexjob, Corntrigger, RecordType, ApexClass, ApexComponent ,ApexPage we can access without (seeAllData=true) .
21. SeeAllData=true will not work for API 23 version eailer .
22. Accessing static resource test records in test class e,g List<Account> accList=Test.loadData(Account,SobjectType,'ResourceName').
23. Create TestFactory class with @isTest annotation to exclude from organization code size limit .
24. @testSetup to create test records once in a method  and use in every test method in the test class .
25. We can run unit test by using Salesforce Standard UI,Force.com IDE ,Console ,API.
26. Maximum number of test classes run per 24 hour of period is  not grater of 500 or 10 multiplication of test classes of your organization.
27. As apex runs in system mode so the permission and record sharing are not taken into account . So we need to use system.runAs to enforce record sharing .
28. System.runAs will not enforce user permission or field level permission .
29. Every test to runAs count against the total number of DML issued in the process .

Use this code it is short and simple.
@isTest
public class TestRestrictContactByName {
    public static Contact c1=new Contact();
     @isTest static void TestLastNameOfContact()
     {
         c1.LastName='INVALIDNAME';
         //insert c1;
         Test.startTest();
         Database.SaveResult r=Database.insert(c1,false);
         Test.stopTest();
         System.assertEquals(c1.LastName,'error');    
     }
}

You can try this code as well, it has two methods and both methods will pass the test. For sure you will get 100% code coverage.

@isTest
public class TestRestrictContactByName
{
    
    private static testMethod void myMethod1()
    {
        List<Contact> cons=new List<Contact>();
        Contact c1=new Contact();
             c1.FirstName='Test';
             c1.LastName='InvalidName';
             cons.add(c1);
        try{
             insert c1;
           }
        Catch(DMLexception e)
           {
            System.assertEquals('The Last Name "'+c1.LastName+'" is not allowed for DML',e.getDmlMessage(0));
           }
    }
   
 Public static testMethod void myMethod2()
    {
        List<Contact> cons=new List<Contact>();
        Contact c2=new Contact();
        c2.FirstName='Test';

Hello, my unit test gave me 100% code coverage, but it failed the test run returning the following errors:

System.AssertException: Assertion Failed
Class.TestRestrictContactByName.TestLastNameIsvalid: line 35, column 1


I've spent hours trying to figure out why but couldn't. I wonder if any of you was able to help and provide me with some insights here?  Your help will be much appreciated!
@isTest
private class TestRestrictContactByName {
    
    @isTest static void TestLastNameIsNotInvalid() {
        // Test data setup

    	Contact c = new Contact(LastName='INVALIDNAME');
    	insert c;
        
        // Perform test
        Test.startTest();
        Database.SaveResult result = Database.insert(c, false);
        Test.stopTest();
        // Verify 
        // In this case the deletion should have been stopped by the trigger,
        // so verify that we got back an error.

Hi guys,

I finished the challenge, but I was really disappointed because I'm sure I didn't really tested every options...

Here is my code :
 

@isTest
private class TestRestrictContactByName {
    
    Static testmethod void TestAjoutListe () {
    
        // liste de datas : les elements ci donnees en dur, sont mis entre ACCOLADES
        // le premier contact doit passer, le second non
        List <Contact> contList2 = new List <Contact> {
            new Contact(firstName='Al', lastName='Douz'),
            new Contact(firstName='DonneeTest', lastName='INVALIDNAME')};
    
		// perform test : tentative d'upsert
		Test.startTest();
        Database.UpsertResult[] UpResult = database.upsert(contList2, false);
        Test.stopTest();
        
        // on boucle sur les resultats
        for (Database.UpsertResult dr : UpResult) {
            if(dr.isSuccess()!=true) {
				System.debug('Not a success : good thing !');           
            }
        }
	}
}

Do you know why it worked ?
How can I improve it ?

I tried to interrogate the size of the errors on my list, but I think I still have an issue understanding how works the Database.SaveResult (or Database.UpsertResult) objects ... Is there a list of lists, in which there are couples (objectToUpsert, SuccessOrNot) ?
// System.debug('Taille liste err ' + UpResult. getErrors().size());
            //System.assert(UpResult.getErrors().size() = 0);


Nb : I don't know if I should open my own topic for asking this ?

Sorry, I'm learning :)

@TinaChang6 - I had written nearly identical code to you. From browsing all the posts, I think the moral of this challenge/unit is that for the "fail" (for the insert that will be blocked by the trigger), that needs to happen in a try/catch like  you see in the post by David Adu Smith back in January 2016. 

Message to Salesforce Training developers: The Unit needs work!  You don't explain any of that in the unit - we follow your lead for how it's presented in the unit, but you have left too much out for this unit. If it weren't for this forum it would take tons of research to work it out!

Was able to clear the challenge using upsert instead of insert contact.
Below is the snippet code :
@istest
public class TestRestrictContactByName {

    public static testmethod void TestContact(){
       List<contact> con = new list<contact>();
    contact c1= new contact(FirstName='Sohan',LastName='V');
        contact c2= new contact(FirstName='V',Lastname='INVALIDNAME');
        con.add(c1);
        con.add(c2);
        Test.startTest();
        try{
            upsert con;
        }
        catch(exception e){
            
        }
        Test.stopTest();
    }
}

Use this code, I am Sure it will work !!!
Always try to run new test after modifying test class then it will only show you 100% coverage.

Reason: Coz when you rerun test already contact is created with name provided by you during new run. And when you run new test it will first delete older one and insert new one with provided name.



@isTest
private class TestRestrictContactByName {
    
    @isTest static void CheckContact(){
        
       
        Contact con = new Contact(FirstName='testDemo',LastName= 'Singh');
                insert con;
        
        con.LastName = 'INVALIDNAME';  
        
        Test.startTest();
        
        try{
                update con;
            } 
        catch (DmlException e {

            String expectedMessage = 'The Last Name INVALIDNAME is not allowed for DML';
            System.assertEquals(expectedMessage, e.getDmlMessage(0));

@Siddhi Salvekar, you have given perfect solution in entire thread. Mine is also matching with you but you have used both ways to assert the results.

@isTest
public class TestRestrictContactByName {

    @isTest static void TestContactLastName(){
     
    Contact cnt = new Contact(LastName='Nagpal', FirstName='Namit');
    Contact cnt1 = new Contact(LastName='INVALIDNAME', FirstName='Hardik');
    // Insert Valid record    
    insert cnt;
    // Perform test
    Test.startTest();
    
        // Perform test - Update contact with LastName = 'INVALIDNAME'
        cnt.LastName = 'INVALIDNAME';
        try{
        update cnt;
        }
        catch(DMLException e){
             System.assertEquals('The Last Name "'+cnt.LastName+'" is not allowed for DML',e.getDMLmessage(0));
        }
    
        // Perform test - Insert contact with LastName = 'INVALIDNAME'
        try{
        insert cnt1;
        }
        catch(DMLException e){
            System.assertEquals('The Last Name "'+cnt1.LastName+'" is not allowed for DML',e.getDMLmessage(0));
        }
    Test.stopTest();
    }
}

Please let me know if above solution resolved your problem.

Thank you each and everyone. please be more helpful.

If you are getting 'invalid parameter value' error while trying  to save your  RestrictContactByName class in developer console,  try creating the trigger via objectmanager (contact). Also you may need to close and reopen your developer console and open the trigger in there again.
Frank J. PerriconeFrank J. Perricone
Astha, did you perhaps enter the RestrictContactByName as a class instead of a trigger?
