Hello everyone,

Is there any solution for finishpage. It worked great when I have extension controller. However I couldn't create test class. Can anyone help with test class thanks.

<apex:page standardController="GW_Volunteers__Volunteer_Job__c" tabStyle="GW_Volunteers__Volunteer_Job__c" extensions="FlowRedirectController"> <flow:interview name="GIGI_SyncProgVolToPlay_ProgVolJob1" interview="{!redirectTo}" finishLocation="{!finishLocation}" > <apex:param name="VarId" value="{!GW_Volunteers__Volunteer_Job__c.Id}"/> <apex:param name="AlreadySynced" value="{!GW_Volunteers__Volunteer_Job__c.SyncedSuccessfully__c}"/> <apex:param name="VarPrgName" value="{!GW_Volunteers__Volunteer_Job__c.Name}"/> </flow:interview> </apex:page>


Extension class:
Public class FlowRedirectController{

    public FlowRedirectController(ApexPages.StandardController controller) {

    }

    Public Flow.Interview.GIGI_SyncProgVolToPlay_ProgVolJob1 redirectTo {get; set;}

    public FlowRedirectController() {
        Map<String, Object> redirectURL = new Map<String, Object>();
        
        //vFinishLocation is the name of a variable from your Flow containing the Id of your newly created Opportunity
        redirectURL.put('VarId','https://gigisplayhouse--volprogvf.cs45.my.salesforce.com/');
        redirectTo = new Flow.Interview.GIGI_SyncProgVolToPlay_ProgVolJob1(redirectURL);
    }

    Public PageReference getFinishLocation(){
     string strID = ApexPages.currentPage().getParameters().get('Id');
        String finishLocation;
        if(redirectTo != null) {
            finishLocation = (string) redirectTo.getVariableValue('VarId');
        }
        else
        {
        finishLocation=strID;
        }
        PageReference send = new PageReference('/' + finishLocation);
        send.setRedirect(true);
        return send;
    }
}

Test class:
@isTest
private class FlowRedirectControllerTest{

    static testmethod void SetVariablesTests() {
    
    
      //Insert Campaign
    Campaign sCmp = new Campaign(Name='TestClassCamp',Status='Active');
    insert sCmp;
     System.debug('inserted campaigns . athi ' );
   
    // Retrieve the new campaign
    sCmp = [SELECT Id,Name FROM Campaign WHERE Id =:sCmp.Id LIMIT 1];
 
 
         //Insert prog job
    GW_Volunteers__Volunteer_Job__c vol=new GW_Volunteers__Volunteer_Job__c(Name='TestJob', GW_Volunteers__Campaign__c =sCmp.id, GW_Volunteers__Description__c ='Hellow', GW_Volunteers__Display_on_Website__c=true);
        insert Vol;
    // System.debug('inserted  Jobs. athi ' );
   
    // Retrieve the new prog Job
  vol = [SELECT Id,Name, GW_Volunteers__Campaign__c, GW_Volunteers__Display_on_Website__c FROM GW_Volunteers__Volunteer_Job__c WHERE Id =:vol.Id LIMIT 1];
     Test.startTest();
        //VFFLow is the name of the VisualForce page which you create
        PageReference pageRef = Page.GIGI_SyncProgJobToPlayVF;
        Test.setCurrentPage(pageRef);
        System.currentPageReference().getParameters().put('Id',Vol.Id);
        FlowRedirectController testCtrl = new FlowRedirectController();
        testCtrl.redirectTo = new Flow.Interview.GIGI_SyncProgVolToPlay_ProgVolJob1(new Map<String, Object>());
        testCtrl.redirectTo.start();

        testCtrl.getFinishLocation();
        Test.StopTest();
      //  System.assertEquals(testCtrl.getFinishLocation().getUrl(), 'https://gigisplayhouse--volprogvf.cs45.my.salesforce.com/');
    }
}

Thanks in advance
