Ragnar Lothbrok 7 How to start / write the Apex test class ?
Hello,
I am new to Apex coding, and also I am not comfortable to write test class. Can anyone help me to write the test class for this Apex class method. And also if you can suggest me how to start on writing test class so that i can also create one.
Apex Class Method :
Thanks.

Thanks.
Please learn to write the test class from this salesforce official site Trailhead (https://trailhead.salesforce.com/en/content/learn/modules/apex_testing/apex_testing_intro)
Kindly mark it as the best answer if it works for you.
Thanks & Regards,

Please use the below code for your converage. Try to also read through what Priya shared. This code will help you along with your reading.
You may or may not need to tweak how your wrapper class look like, since you didn't shared. I made mine based on how it is used in the code you shared. it gave me 87% code coverage.
@isTest public class opportunityProductCreationTest { //setup is a special method which is use to prep your data once to be use by multiple testmethods @testSetup static void setup() { Account testAccount = new Account (Name = 'Test Account'); insert testAccount; Opportunity opportunity = new Opportunity( Name = 'Test Opportunity', AccountId = testAccount.Id, CloseDate = Date.today(), StageName = 'Prospecting' ); insert opportunity; Product2 product = new Product2 ( Name = 'Test Product', IsActive = true ); insert product; //Instantiate the Pricebook2 record with StandardPricebookId Pricebook2 standardPricebook = new Pricebook2( Id = Test.getStandardPricebookId(), IsActive = true ); //Execute an update DML on the Pricebook2 record, to make IsStandard to true Update standardPricebook; PricebookEntry priceBookEntry = new PricebookEntry( Pricebook2Id=standardPricebook.Id, Product2Id = product.Id, UnitPrice = 10.0, IsActive = true ); insert priceBookEntry; } @isTest static void testopportunityProductCreation() { Opportunity opp = [SELECT Id FROM Opportunity LIMIT 1]; Product2 product = [SELECT Id FROM Product2 LIMIT 1]; Id prdIdset = [SELECT Id FROM Product2 LIMIT 1].Id; OpportunityLineItemWrapper oliwrapper = new OpportunityLineItemWrapper(); oliwrapper.selectedProductId = product.Id; oliwrapper.resalePrice = '10.00'; oliwrapper.targetCost = '20.00'; oliwrapper.mPrice = '30.00'; oliwrapper.competitor = 'Test Competitor'; oliwrapper.orderQuantity = '100.00'; oliwrapper.perUnit = '5.00'; List<OpportunityLineItemWrapper> oliwrapperList = new List<OpportunityLineItemWrapper>{ oliwrapper }; Test.startTest(); opportunityProductCreation.opportunityProductCreation(opp.Id, oliwrapperList); Test.stopTest(); OpportunityLineItem oli = [SELECT CompetitorName__c, ResalePrice__c , TargetPrice1__c, Quantity, UnitPrice , Price1__c, PriceUnit__c, PriceCurrency1__c FROM OpportunityLineItem WHERE OpportunityId = :opp.Id]; system.assert(oli.CompetitorName__c == oliwrapper.competitor); system.assert(oli.ResalePrice__c == Decimal.valueOf(oliwrapper.resalePrice)); system.assert(oli.TargetPrice1__c == Decimal.valueOf(oliwrapper.targetCost)); system.assert(oli.Quantity == Decimal.valueOf(oliwrapper.orderQuantity)); system.assert(oli.Price1__c == Decimal.valueOf(oliwrapper.mPrice)); system.assert(oli.PriceUnit__c == Decimal.valueOf(oliwrapper.perUnit)); system.assert(oli.UnitPrice == Decimal.valueOf(oliwrapper.mPrice)); } }Was the test class helpful?
