Hi,

I  have a trigger that generates the password based on a picklist value I had some problem with the test class can any one help.

Trigger

trigger Sendpassword on Contact (before update, before insert) {

   if(!Validator_cls.hasAlreadyDone()){
   string tokenM;
   
   if(trigger.isInsert){
   
   List<Contact> con =Trigger.new;
   Integer len = 8;
    Blob blobkey = crypto.generateAesKey(128);
    String key = EncodingUtil.convertToHex(blobKey);
    tokenM = key.substring(0,len).toUpperCase();
   
   for (Contact tpwd : con) {
   
   if(tpwd.Temporary_KL_Login__c=='Enable and Send Password'  )
   tpwd.Temporary_KL_Login_Password__c =tokenM;
 
   }
   }
      
   if(trigger.isUpdate){
 
   Contact conn= Trigger.old[0];
   List<Contact> con =Trigger.new;
   Integer len = 8;
    Blob blobkey = crypto.generateAesKey(128);
    String key = EncodingUtil.convertToHex(blobKey);
    tokenM = key.substring(0,len).toUpperCase();
   
   for (Contact tpwd : con) {
   
   if(tpwd.Temporary_KL_Login__c=='Enable and Send Password' && conn.Temporary_KL_Login__c != tpwd.Temporary_KL_Login__c )
   tpwd.Temporary_KL_Login_Password__c =tokenM;
 
   }
   }
   Validator_cls.setAlreadyDone();
}
}

Test class

@isTest

Public class Sendpassword
{
static testMethod void Sendpassword()
{
Contact con = new Contact(LastName='Test', Title = 'testt' ,
                           Phone = '4561230789' , Email = 'qwwervvsv@gmail.com' ,Temporary_KL_Login_Password__c='78B910FC' );

insert con;

con.Phone ='4561230789';

update con;

Validator_cls.hasAlreadyDone();
}
}

i am getting  54% code coverage unable to cover the things inside the "trigger.isUpdate"

I used another class "Validator_cls" to make the trigger fire only once

Validator_cls

global class Validator_cls{

    private static boolean blnAlreadyDone = false;
    
    public static boolean hasAlreadyDone(){
        return blnAlreadyDone;
    }
         public static void setAlreadyDone() {       
            blnAlreadyDone = true;
    }
    

}
