Test Class coverage on Case attachment

I have a trigger that prompts the user to include an attachment before saving a case record. Can someone please help me with the test class that provides a 100% code coverage.  
trigger CaseAttachment on Case (before update) {
    
    for (Case myCase : Trigger.New) {
        if (myCase.Status == 'Repair Confirmed') {
            
            Attachment myAttachment = new Attachment();
            
            try {
                myAttachment = [Select Id, Name from Attachment where ParentId = :myCase.Id];
            }
         
            catch (Exception e)  {
                myAttachment = null;
            } 
                
                
                if (myAttachment ==null)
                    myCase.addError ('Add picture to the record');
                
                
            }
            
            
                
        }
        
        
    }

Hi Porty,

Test Class coverage on Case attachment. This test class is 100% code coverage.
  
@isTest
public class CaseAttachmentTest {
    @isTest public static void CaseAttachmentMethod()
    {
        Case caseObj = new Case();
        caseObj.Status = 'Closed';
        caseObj.Origin = 'Phone';
        insert caseObj;
        
        Attachment attachmentObj = new Attachment();
        attachmentObj.Name='Unit Test Attachment';
        Blob bodyBlob=Blob.valueOf('Unit Test Attachment Body');
        attachmentObj.body=bodyBlob;
        attachmentObj.parentId=caseObj.id;
        insert attachmentObj;
        
        Case caseUpdateOject = new Case();
        caseUpdateOject = [Select Status,Origin from Case where Id = :caseObj.Id];
        caseUpdateOject.Status= 'Repair Confirmed';
        update caseUpdateOject;
    }
    @isTest public static void CaseAttachmentMethodException()
    {
        Case caseObj = new Case();
        caseObj.Status = 'Closed';
        caseObj.Origin = 'Phone';
        insert caseObj;
        
        Case caseUpdateOject = new Case();
        caseUpdateOject = [Select Status,Origin from Case where Id = :caseObj.Id];
        caseUpdateOject.Status= 'Repair Confirmed';
        update caseUpdateOject;
    }

}

I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.

Hi Ajay, i was hoping you could help me with the trigger. Everything works fine in checking for an attachment. Problem is, after inserting the attachment and wanting to save the record, i still get an error asking me to add attachment to the record. Cab you review for me please?
