Hi all,

I use apex trigger to auto complete a milestone "Response Time", it works but I have to create a test apex class to import it in production and the code coverage is only 70%.

Can you help me?

My test class :

@isTest
private class MilestoneTest {

static testMethod void TestCompleteMilestoneCase(){

List<Account> acts = new List<Account>();
Account myAcc = new Account(Name='TestAct', phone='1001231234');
acts.add(myAcc);

Account busAcc = new Account(Name = 'TestForMS', phone='4567890999');
acts.add(busAcc);
insert acts;
Contact cont = new Contact(FirstName = 'Test', LastName = 'LastName', phone='4567890999', accountid = busAcc.id);
insert(cont);

Contact oContact = [select id from Contact limit 1];
        String contactId;
        if (oContact != null)
          contactId = oContact.Id;

Asset ast = new Asset(Name='support platinum', 
                      AccountId=busAcc.Id, 
                      Start_date__c = date.today().addDays(-5), 
                      End_date__c = date.today().addDays(5));
insert ast;

    
ast = [SELECT Id, Name, Active__c, Start_date__c, End_date__c, AccountId FROM Asset WHERE Id=:ast.Id];

    
String astId;
if (astId != null)
astId = ast.Id;    
    
Entitlement entl = new Entitlement(Name='First Response - SUPPORT PLATINUM PLAN - TestForMS', AccountId=busAcc.Id, AssetId = astId, EndDate= date.today().addDays(5), StartDate= date.today());
insert entl;

 String entlId;
if (entl != null)
entlId = entl.Id; 
    

List<Case> cases = new List<Case>{};
if (entlId != null){
	Case c = new Case(Subject = 'Test Case with Entitlement ', 
	EntitlementId = entlId, ContactId = contactId, Description = 'test', Departement__c = 'Centreon', AssetId = astId, Priority = 'Blocking');
	cases.add(c);
}
if (cases.isEmpty()==false){
	insert cases;
    
	List<Id> caseIds = new List<Id>();
	for (Case cL : cases){
		caseIds.add(cL.Id);
	}
	milestoneUtils.completeMilestone(caseIds, 'First Response', System.now());
}
}

}

My apex class MilestoneUtils:

public class MilestoneUtils {
    public static void completeMilestone(List<Id> caseIds, 
            String milestoneName, DateTime complDate) {  
    List<CaseMilestone> cmsToUpdate = [select Id, completionDate
            from CaseMilestone cm
            where caseId in :caseIds and cm.MilestoneType.Name=:milestoneName 
            and completionDate = null limit 1];
    if (cmsToUpdate.isEmpty() == false){
        for (CaseMilestone cm : cmsToUpdate){
            cm.completionDate = complDate;
            }
        update cmsToUpdate;
        }
	else{
		List<CaseMilestone> cmsTest = [select Id, completionDate
            from CaseMilestone cm
            where caseId in :caseIds limit 1];
        update cmsTest;
		}
    }
}

Problem is cmsToUpdate is empty because Case Milestione isn't created. 
I don't understand why
