Steps to create test class in trigger

Hi, 

 I have a trigger and a helper class created need a suggestion on how to create a test class for below
trigger RenwalQuote on QuoteLineItem (After Insert, After Update, Before Delete) {
 
 public static Boolean bool = true;
 Set<Id> setid = new Set<id>();
 List<QuoteLineItem> listoli = new  List<QuoteLineItem> ();
 List< OpportunitylineItem> lisopt = new  List< OpportunitylineItem > ();
 List< OpportunitylineItem> Dellisopt = new  List< OpportunitylineItem > ();
 set<id> setoppid = new set<id>();
 set<string> setprodcode = new set<string>();
 set<string> setrecordtype = new set<string>();
 Set<Id> setoldid = new Set<id>();
    
  if(trigger.isafter){
      
   If(preventRecursive.runOnce)return;
   if(bool){
      bool = false;
 
      for (QuoteLineItem qtl :  Trigger.new){
         setid.add(qtl.id);
        }
   } 
 
   List<QuoteLineItem> listem = [Select id,quoteid,Prior_Discount__c,product2.productcode,quote.opportunityid,
                                        quote.opportunity.recordtype.name                   
                                 from QuoteLineItem where id In : Setid];
   
   for(QuoteLineItem qlt:listem){
       
         if ( qlt.quote.opportunity.recordtype.name == 'Renewal Opportunity'){
          qlt.Prior_Discount__c = RenewalUtils.OppLineDisc(qlt.quote.opportunityid,qlt.quoteid,qlt.product2.productcode);
          qlt.Opportunity_Line_Item_ID__c = RenewalUtils.OppLineID(qlt.quote.opportunityid,qlt.quoteid,qlt.product2.productcode);
          system.debug('Quote ID' + qlt.quoteid);

         }
      } 
       
        if (!listoli.isEmpty()){
          preventRecursive.runOnce = true; update listoli;
                                     
         Opportunity Opp = [select id, Prior_Year_Opportunity__c from Opportunity where id = :setoppid];

           if (!lisopt.isEmpty()){
              update lisopt;
            }  
  
       }
   }    
   
      if(Trigger.isbefore){
      
         for (QuoteLineItem qtl :  Trigger.old){

                }  
        
        
      }
      
}

Please check below post to learn about test class
1)http://amitsalesforce.blogspot.com/2017/02/salesforce-tutorial-how-to-learn-test.html
2) http://amitsalesforce.blogspot.com/2015/06/best-practice-for-test-classes-sample.html

Sample code to start
@IsTest
private class RenwalQuoteTest 
{

    private static testmethod void testupdateQuoteLineItem()
	{

		Account objaccount=new Account();
		objaccount.Name='TestAccount';
		insert objaccount;

		Product2 objProduct2=new Product2();
		objProduct2.Name='ABC';
		objProduct2.CurrencyIsoCode='USD';
		insert objProduct2;

		PriceBook2  objPricebook2= new PriceBook2();

Please follow below salesforce Best Practice for Test Classes :-

1. Test class must start with @isTest annotation if class class version is more than 25
2. Test environment support @testVisible , @testSetUp as well
3. Unit test is to test particular piece of code working properly or not .
4. Unit test method takes no argument ,commit no data to database ,send no email ,flagged with testMethod keyword .
5. To deploy to production at-least 75% code coverage is required
6. System.debug statement are not counted as a part of apex code limit.
7. Test method and test classes are not counted as a part of code limit
9. We should not focus on the  percentage of code coverage ,we should make sure that every use case should covered including positive, negative,bulk and single record .
Single Action -To verify that the the single record produces the correct an expected result .
Bulk action -Any apex record trigger ,class or extension must be invoked for 1-200 records .
Positive behavior : Test every expected behavior occurs through every expected permutation , i,e user filled out every correctly data and not go past the limit .
Negative Testcase :-Not to add future date , Not to specify negative amount.
Restricted User :-Test whether a user with restricted access used in your code .
10. Test class should be annotated with @isTest .
11 . @isTest annotation with test method  is equivalent to testMethod keyword .
12. Test method should static and no void return type .
13. Test class and method default access is private ,no matter to add access specifier .
14. classes with @isTest annotation can't be a interface or enum .
15. Test method code can't be invoked by non test request .
16. Stating with salesforce API 28.0 test method can not reside inside non test classes .
17. @Testvisible annotation to make visible private methods inside test classes.
18. Test method can not be used to test web-service call out . Please use call out mock .
19. You can't  send email from test method.
20.User, profile, organization, AsyncApexjob, Corntrigger, RecordType, ApexClass, ApexComponent ,ApexPage we can access without (seeAllData=true) .
21. SeeAllData=true will not work for API 23 version eailer .
22. Accessing static resource test records in test class e,g List<Account> accList=Test.loadData(Account,SobjectType,'ResourceName').
23. Create TestFactory class with @isTest annotation to exclude from organization code size limit .
24. @testSetup to create test records once in a method  and use in every test method in the test class .
25. We can run unit test by using Salesforce Standard UI,Force.com IDE ,Console ,API.
26. Maximum number of test classes run per 24 hour of period is  not grater of 500 or 10 multiplication of test classes of your organization.
27. As apex runs in system mode so the permission and record sharing are not taken into account . So we need to use system.runAs to enforce record sharing .
28. System.runAs will not enforce user permission or field level permission .
29. Every test to runAs count against the total number of DML issued in the process .

Thanks Amith for your reply this is very helpfull can you help me with the helper class below how to write the test class

 
public with sharing class RenewalUtils {

 public static String OppLineDisc(String QOppID, String Quoteid, String ProdCode) {
 
   Decimal Disctot;
   
   Opportunity ropp = [select Prior_Year_Opportunity__c from opportunity where id = :QOppID and recordtype.name = 'Renewal Opportunity']; 
 
   List<AggregateResult>  Opplst = [select avg(Discount_Percent__c) totdisc
                                    from OpportunityLineItem 
                                    where Opportunityid = :ropp.Prior_Year_Opportunity__c and 
                                          product2.productcode = :ProdCode 
                                          ];
                           
   for (AggregateResult arOpplst : Opplst)
     {
       Disctot = ((Decimal)arOpplst.get('totdisc'));
       
     }                                              
                        
     system.debug(Disctot);
                                              
      return string.valueof(Disctot);
 
 }
 
 
public static String OppLineID(String QOppID, String Quoteid, String ProdCode) {
 
   
   Opportunity ropp = [select Prior_Year_Opportunity__c from opportunity where id = :QOppID and recordtype.name = 'Renewal Opportunity']; 
 
   OpportunityLineItem  Opplst = [select id
                                    from OpportunityLineItem 
                                    where Opportunityid = :ropp.Prior_Year_Opportunity__c and 
                                          product2.productcode = :ProdCode limit 1
                                          ];
                    
     system.debug(Opplst.id);
                                              
      return string.valueof(Opplst.id);
 
 }

Hi Sudhir,

Please check in Developer console which lines are cover and which lines are not covered ?

Call the helper class from trigger and create a object for the helper class in the test class that solves the problem
