How to write test class for below Vf Page Controller [duplicate]

Question

Class

public with sharing class CreateQuotePDFController {
    public list<QuoteLineItem> quoteLineItemsList{get;set;}
    public Id getid{get;set;} 
    public Double grandTotalTax{get;set;}
    public Double finalPO{get;set;}
    public Date expirationDate{get;set;}
    public CreateQuotePDFController(ApexPages.StandardController controller) {
        getid=ApexPages.currentPage().getParameters().get('id');
        Quote quote = [SELECT Account.Name, Account.BillingCountry,Account.BillingPostalCode,Account.BillingState,Account.BillingCity,Account.BillingStreet, Contact.Name, GrandTotal, ExpirationDate FROM quote where id=:getid ];
        quoteLineItemsList = [select id,product2id,Discount_Percentage__c, PricebookEntry.Product2.Name , UnitPrice, Quantity, Subtotal from quotelineitem where QuoteId=: getid];        
        System.debug('grand total is : ' +quote.GrandTotal);
        grandTotalTax = (quote.GrandTotal * 0.18).setScale(2);
        finalPO = (quote.GrandTotal+grandTotalTax).setScale(2);
        expirationDate = quote.ExpirationDate;
    }
}

I tried the below code but its not working
