How to write test class for apex class and trigger

Hi, 

  I wrote a trigger which called apex class need a suggestion how to write the logic to get code coverage for test class. 

Apex Class 
public with sharing class ApprovalUtils {

  /* Subscription Discount Level 1 */
  public static Integer SubLevel1(Decimal Subscription, Decimal ACV, Decimal Discount) {
    
   Integer L1Count;

              Type__c = 'Subscription' and 
              Subscription_Term__c = :Subscription and
              ACV_Lower__c <= :ACV  and ACV_Upper__c >= :ACV and

What have you done so far on the test class? Or are you asking someone to write it for you?
GMASJGMASJ
Hi George, 

  I wrote below test class for trigger and apex class both in a single test class 

  
@isTest(SeeAllData = true)
private class ApprovalUtils_Test {

        static testMethod void Approval(){
 
                 test.startTest();
                 
                 ApprovalUtils.SubLevel1(1,0,0);
                 ApprovalUtils.SubLevel2(1,0,10);
                 ApprovalUtils.SubLevel3(1,0,11);
                 ApprovalUtils.SubLevel4(1,0,41);
               
                 ApprovalUtils.SerLevel1(1,1);
                 ApprovalUtils.SerLevel2(1,10);
                 ApprovalUtils.SerLevel3(1,41);
                 
                 List<Account> lstAccount =   new List<Account>{
                          new Account(name = 'samarth', Email_Domain__c = 'samarth.com')

                         };
                         
                 insert lstAccount;
         

                 List<Opportunity> lstOpportunity =   new List<Opportunity>{
                     new Opportunity(AccountId = lstAccount[0].id,name='sudhir',type='New Customer',closedate=System.today(),StageName='Booked',ForecastCategoryName='Closed',Pricebook2Id='01s800000007nNeAAI')
                  }; 
                 insert lstOpportunity;
                 
                 List<Quote> lstQuote =   new List<Quote>{
                     new Quote(OpportunityId = lstOpportunity[0].id,name='sudhirquote')
                 };  
                 insert lstQuote;
                 
                 //Product2 prod = [select id,name from product2 where name = 'Couchbase Enterprise Edition Server /M Gold'];
 
                 
                 List<QuoteLineItem> lstQuotelineitem =   new List<QuoteLineItem>{
                     new QuoteLineItem(QuoteId = lstQuote[0].id,discount=1,Quantity=1,PricebookEntryId='01u8000000CrSczAAF' , UnitPrice=8316, Product2Id='01t800000049k93AAA')
                 };  
                 insert lstQuotelineitem;
                 
                 
                 
                 test.stopTest();
     }     
 }

I am having issue with last item inserting into quotelineitem I keep gettng below error Please suggest how to fix this issue

List<QuoteLineItem> lstQuotelineitem = new List<QuoteLineItem>{ new QuoteLineItem(QuoteId = lstQuote[0].id,discount=1,Quantity=1,PricebookEntryId='01u8000000CrSczAAF' , UnitPrice=8316, Product2Id='01t800000049k93AAA') }; insert lstQuotelineitem;

Thanks

 What's the error you're getting for that part?
GMASJGMASJ

Hi George, 

 I get below error sorry missed to paste this error in earlier thread

System.DmlException: Insert failed. First exception on row 0; first error: FIELD_INTEGRITY_EXCEPTION, The pricebook entry is in a different pricebook than the one assigned to the Quote, or Quote has no pricebook assigned.: [PricebookEntryId]

Thanks

Hi George, 

  Can you suggest me how to write test class logic for trigger I am not able to get code coverage at all it shows 0% 

Thanks
Sudhir
