Need assistance with a TestClass for a Page Routing Class

Question

I am stuck trying to figure out how to test the following Class: This Class is loaded when a user clicks on a Case detail link and I have an override on View for the Case Object which loads a VF page that then executes the CaseDetailRedirectCode() method below. The method routes the user to the correct case detail page based on their profile.

I have a Test Class so far that creates an Account, Contact and a Community user under said Contact and a new Case owned by said Account and Contact. This is most likely not complicated but I am at a loss on where to go from here.

public class CaseDetailRedirect {

    public Id RecordId { get; set; }

    public CaseDetailRedirect(ApexPages.StandardController stdController) {
        RecordId = stdController.getId();  
    }

    public pagereference CaseDetailRedirectCode() {
      Profile p = [Select Name from Profile where Id =:userinfo.getProfileid()];
      String pname = p.name;

    //check if Profile Name is the Support Community Profile    
      if (pname.equals('Support Community Login user')) {  
        return new PageReference('/CaseDetail?id=' + RecordId);
    } else {       
        return new PageReference('/' + RecordId + '?nooverride=1');
        }
    }    

}

Answer 1

First, I'd recommend not using String.equals: it is case sensitive. Just use the normal == equals comparison. Second, I'd recommend using a Custom Label to avoid hard-coding the value in your code. Third, public Id RecordId { get; set; } could also be written as Id RecordId;, unless it needs to appear on the page.

All that aside, to test this, you just need two users to test as. Here's how I might write a test:

@isTest static void test() {
  Case c = new Case( /* required fields here */ );
  insert c;
  CaseDetailRedirect cdr = new CaseDetailRedirect(new ApexPages.StandardController(c));
  System.assert(cdr.casedetailredirectcode().geturl().contains('nooverride=1'));

  User tempUser = new User(
    ProfileId=[SELECT Id FROM Profile WHERE Id = :Label.SupportCommunityLoginUser].Id
    /* and add other required fields */);
  System.runA(tempUser) {
    System.assert(cdr.casedetailredirectcode().geturl().contains('/CaseDetail'));
  }
}

Answer 2

I would do as following:

Case myTestCase; //Assuming this is your properly created and database stored Case object.

ApexPages.StandardController stdCase = new ApexPages.StandardController(myTestCase);
CaseDetailRedirect  ctrExtension=new CaseDetailRedirect(myTestCase);
ctrExtension.CaseDetailRedirectCode();
