I am stuck with Data Integration Specialist superbadge challenge ⌗4. While trying to run the test i am getting an error 'Methods defined as TestMethod do not support Web service callouts'. Below are my code:@IsTestpublic class ProjectCalloutServiceMock implements HttpCallOutMock{ //Implement http mock callout here public HttpResponse respond(HttpRequest req) { HttpResponse res = new HttpResponse(); res.setHeader('Content-Type', 'application/json'); res.setStatus('OK'); res.setStatusCode(201); return res; }}@Istestpublic class ProjectCalloutServiceMockFailure implements HttpCallOutMock { //Implement http mock callout failure here public HttpResponse respond(HttpRequest req) { HttpResponse res = new HttpResponse(); res.setHeader('Content-Type', 'application/json'); res.setStatus('Error'); res.setStatusCode(500); return res; }}@isTestprivate class ProjectCalloutServiceTest { //Implement mock callout tests here @testsetup public static void setupdata() { List<Opportunity> oppsToInsert = new List<Opportunity>(); Account acct = new Account(); acct.Name='test Account'; insert acct; Opportunity opp1 = new Opportunity(); opp1.Name = 'Opp1'; opp1.Type='New Customer'; opp1.AccountId = acct.id; opp1.amount=500; opp1.CloseDate = date.today(); opp1.StageName = 'Prospecting'; oppsToInsert.add(opp1); Opportunity opp2 = new Opportunity(); opp2.Name = 'Opp2'; opp2.Type='New Customer'; opp2.AccountId = acct.id; opp2.amount=2500; opp2.CloseDate = date.today().addDays(-3); opp2.StageName = 'Prospecting'; oppsToInsert.add(opp2); insert oppsToInsert; ServiceTokens__c st = new ServiceTokens__c(); st.Name = 'ProjectServiceToken'; st.Token__c = 'thisistesttoken'; insert st; } @istest public static void testSuccessMessage() { Opportunity oppList = [Select Id from Opportunity where Name='Opp1' limit 1]; List<Id> oppIds = new List<Id>(); oppIds.add(oppList.Id); Test.setMock(HttpCalloutMock.class, new ProjectCalloutServiceMock()); test.startTest(); ProjectCalloutService.postOpportunityToPMS(oppIds); test.stopTest(); oppList = [Select StageName from Opportunity where Name='Opp1' limit 1]; system.assertEquals('Submitted Project',oppList.StageName); } @istest public static void testFailureMessage() { Opportunity oppList = [Select Id from Opportunity where Name='Opp2' limit 1]; List<Id> oppIds = new List<Id>(); oppIds.add(oppList.Id); Test.setMock(HttpCalloutMock.class, new ProjectCalloutServiceMockFailure()); test.startTest(); ProjectCalloutService.postOpportunityToPMS(oppIds); test.stopTest(); oppList = [Select StageName from Opportunity where Name='Opp2' limit 1]; system.assertEquals('Resubmit Project',oppList.StageName); }}
