I have the below triggers and test class for them, Trigger-1 has 85% coverage and Trigger-2 has 66%, can anyone please help me in improving code coverage? Highlighted lines in bold which are not covering 

Trigger-1:   

    trigger AccountName_Opp on Opportunity (before insert, before update ){
    
        Map<String, Opportunity> OppMap = new Map<String, Opportunity>();
    
        for(Opportunity opp:Trigger.new)
        {
            OppMap.put(opp.Account_Name__c, opp);
    
        }
    
        List<Account> accLst = [SELECT ID, Name FROM Account where Name in :OppMap.keySet()];
    
        for(Account acct : accLst){
            OppMap.get(acct.Name).AccountId = acct.ID;
        }
    }

Trigger-2: 

    trigger AccountName_Contact on Contact (before insert, before update ){
    
        Set<String> conaccounts = new Set<String>();
    
        for(Contact con:Trigger.new)
        {
            conaccounts.add(con.Account_Name__c);
        }
    
        List<Account> accLst = [SELECT ID, Name FROM Account where Name in :conaccounts];
        System.debug(accLst);
        for(Account acct : accLst){
            for(Contact co : Trigger.new){
                if(co.Account_Name__c == acct.Name)
                    co.accountid = acct.id;
            }        
        }
    
    }

Testclass:
 

    @istest
    public class FFCNAccountName
    {
      static testmethod void myTest()
      {
        Map<String, Opportunity> OppMap = new Map<String, Opportunity>();
        
        Account acc = new Account(Name = 'test', phone = '1234567890');
        insert acc;
        
        Opportunity opp = new Opportunity(SaleType__c = 'new', Name = 'test', AccountId = acc.Id, Amount = 50, CurrencyIsoCode = 'USD');
        insert opp;
        
        Contact con = new Contact( LastName = 'Test2', Email = 'test.user@gmail.com', AccountId = acc.Id );
        insert con;
      }
    }
