I am writing a test on the a class where about half the code is inside the classes if statement. How do I cover the if statement?

Here is the test code:

@IsTest private class TestQuoteExtend {

    /* This is a basic test which simulates the primary positive case for the 
       save method in the quoteExt class. */
    public static testmethod void basicSaveTest() {
        
        Opportunity o = TestQuoteExtend.setupTestOpportunity();
        
        /* Construct the standard controller for quote. */
        ApexPages.StandardController con = new ApexPages.StandardController(new quote());


        /* Switch to runtime context */
        Test.startTest();

        /* Construct the quoteExt class */
        QuoteExtend ext = new QuoteExtend(con);
        
          PageReference result = ext.save();
        
        /* Switch back to test context */
        Test.stopTest();

    }
        /* Construct the standard controller for quote. */
        ApexPages.StandardController con = new ApexPages.StandardController(new Quote());

        /* Construct the quoteExt class */
        QuoteExt ext = new QuoteExt(con);

        /* Call save on the ext */
        //ext.save();       

    /* This setup method will create an opportunity with line items and a primary
       contact role for use in various tests. */
    private static Opportunity setupTestOpportunity() {

        /* Create an account */
        Account a = new Account();
        a.name    = 'TEST';
        Database.insert(a);

        /* Get the standard pricebook. There must be a standard pricebook already 
           in the target org.  */
        Pricebook2 pb = [select name, isactive from Pricebook2 where IsStandard = true limit 1];

        if(!pb.isactive) {
            pb.isactive = true;
            Database.update(pb);
        }

        /* Get a valid stage name */
        OpportunityStage stage = [select MasterLabel from OpportunityStage limit 1];

        /* Setup a basic opportunity */
        Opportunity o  = new Opportunity();
        o.Name         = 'TEST';
        o.AccountId    = a.id;
        o.CloseDate    = Date.today();
        o.StageName    = stage.masterlabel;
        o.Pricebook2Id = pb.id;

        /* Create the opportunity */
        Database.insert(o);

        /* Setup a basic Template*/
        PDF_Template__c pd  = new PDF_Template__c();
        pd.Name         = 'English';
        pd.Template_Address__c = 'apex/English';
        
        /* Create the Template */
        Database.insert(pd);        

        /* Setup a basic quote*/
        Quote q  = new Quote();
        q.Name         = 'TEST';
        q.OpportunityId    = o.id;
        q.PDF_Template__c = pd.id;


        /* Create the quote*/
        Database.insert(q);

        /* Create a contact */
        Contact c   = new Contact();
        c.lastname  = 'LASTNAME';
        c.firstname = 'FIRSTNAME';

        Database.insert(c);

        /* Create the opportunity contact role */
        OpportunityContactRole r = new OpportunityContactRole();
        r.ContactId     = c.id;
        r.OpportunityId = o.id;
        r.IsPrimary     = true;
        r.role          = 'ROLE';

        Database.insert(r);

        /* Create a product2 */
        Product2 p = new Product2();
        p.Name     = 'TEST';

        Database.insert(p);

        /* Create a pricebook entry. */
        PricebookEntry pbe = new PricebookEntry();
        pbe.Pricebook2Id = pb.id;
        pbe.Product2Id   = p.id;
        pbe.IsActive     = true;
        pbe.UnitPrice    = 1;

        Database.insert(pbe);

        /* Create a line item */
        OpportunityLineItem i = new OpportunityLineItem();
        i.opportunityId       = o.id;
        i.pricebookentryid    = pbe.id;
        i.quantity            = 1;
        i.unitprice           = 1;

        Database.insert(i);

        /* Set up the opportunity with the related records */
        r.Contact        = c;
        r.Opportunity    = o;
        o.Account        = a;
        i.Opportunity    = o;
        pbe.Product2     = p;
        pbe.Pricebook2   = pb;
        i.PricebookEntry = pbe;

        return o;
        PageReference pref = Page.NewQuoteOverride;
        pref.getParameters().put('o.id',o.id);
        Test.setCurrentPage(pref);

        return o;
        
}
}

Here is the regular class:
