I'm getting a compiler error for this test:

@isTest public class TestDirectMailFilter {

public static testMethod void testMyController() {

Campaign c = new Campaign(); c.Name = 'Jacob for president'; c.Type = 'Direct Mail'; insert c;

ApexPages.StandardController sc = new ApexPages.StandardController(c);
**DirectMailfilter dmf = new DirectMailfilter(sc);**
System.assertEquals(1, dmf.getDmcampaigns().size()); }

The bold line is giving me this error:

Error: Compile Error: Constructor not defined: [DirectMailfilter].(ApexPages.StandardController)

Here is the apex class I am trying to test:

public class DirectMailfilter {
public List<campaign> dmcampaigns {get;private set;} 
public DirectMailfilter(ApexPages.StandardsetController controller) {
         dmcampaigns = [SELECT StartDate, Type, Status, Name 
                     FROM Campaign 
                     WHERE Type = 'Direct Mail'];


Seems like it should be simple, but I'm clearly missing something. What is it?

    looks like your passing in a standard controller in the test, where in your class you have the constructor set up to take a standardSetController – Chris Duncombe Jan 7 '14 at 18:36

    @sfdc_ninja: You should post that as an answer. – Mike Chale Jan 7 '14 at 18:37
  • @MikeChale, just added it, was just glancing through and saw it while test code was running, didn't have time to explain an answer, but now I added it. Thanks – Chris Duncombe Jan 7 '14 at 18:56

In your class the constructor is set up to take a StandardSetController

public DirectMailfilter(ApexPages.StandardsetController controller) 

But in your test code, you are passing it a StandardController

ApexPages.StandardController sc = new ApexPages.StandardController(c); 
DirectMailfilter dmf = new DirectMailfilter(sc);

While I don't know which is correct, the class or the test code, you need to either adjust the test code to take a StandardSetController or adjust the class constructor to take a StandardController. Once they match, you should be all set.

  • That fixed the compiler error. It's giving another one, but I think you've solved the problem. Thanks. – Jacob Jan 7 '14 at 19:55

For StandardSetController you should define the test like below or you can do it in the class or trigger.

PageReference myVfPage = Page.VisualForce API Name;
List<You Custom Object > MyStuff = [ select id  from Your Custom Object Name];
ApexPages.StandardSetController setCon = new ApexPages.StandardSetController(MyStuff);
CustomControllerName ext = new CustomControllerName(setcon);
