I'm new to writing test classes, and I'm having some trouble on this one. It simply shows the Opportunities that a contact is related via contact role. I'm getting the error "Method does not exist or incorrect signature: [OpportunityContactRoles].getocrs()" on the test classApex:public with sharing class OpportunityContactRoles{ private Contact ocr; public OpportunityContactRoles(ApexPages.StandardController controller){ this.ocr = (Contact)controller.getRecord(); } public List<OpportunityContactRole> ocrs{ get{ if (ocrs==null){ ocrs=[Select Id, Opportunity.Name, Role, IsPrimary From OpportunityContactRole WHERE ContactId=:ocr.Id ORDER BY Opportunity.Name, Role]; } return ocrs; } private set; } }VF:<apex:page standardcontroller="Contact" extensions="OpportunityContactRoles"> <apex:outputPanel > <apex:form > <apex:pageBlock > <apex:pageBlockSection columns="1"> <apex:dataTable value="{!ocrs}" var="ocr" id="ocrTable" rules="all" cellpadding="5px"> <apex:column width="300px" headerValue="Opportunity Name"> <apex:outputLink value="/{!ocr.Opportunity.Id}" target="_parent">{!ocr.Opportunity.Name}</apex:outputLink> </apex:column> <apex:column width="150px" headerValue="Role"> <apex:outputText value="{!ocr.Role}"/> </apex:column> </apex:dataTable> </apex:pageBlockSection> </apex:pageBlock> </apex:form> </apex:outputPanel></apex:page>Test Class:@isTestprivate class TestOpportunityContactRoles{ static testMethod void TestOCR() { Account t_a = new Account(Name='TestClassAccount'); insert t_a; Contact t_c = new Contact (Account=t_a, FirstName='Test', LastName='Contact'); insert t_c; Opportunity t_o = new Opportunity (Account=t_a, Name='Test', CloseDate=Date.Today(), StageName='Prospecting'); insert t_o; OpportunityContactRole t_ocr = new OpportunityContactRole (OpportunityId=t_o.Id, ContactId=t_c.Id, Role='Other', IsPrimary=TRUE); insert t_ocr; test.startTest(); PageReference pageRef = Page.OppContactRoles; Test.setCurrentPageReference(pageRef); ApexPages.StandardController sc = new ApexPages.StandardController(t_c); OpportunityContactRoles t_ocrs = new OpportunityContactRoles(sc); LIST<OpportunityContactRoles> c = t_ocrs.getocrs(); //Error system.assertEquals(t_ocr.Id, c[0].Id); }}
