Help with Apex test on PageReference

Question

I have a class

public with sharing class myCurrentController {
    public PageReference myNewPage() {
        return Network.communitiesLanding();
    }
}

My test class is

public with sharing class myCurrentControllerTest {
    @isTest
    public static PageReference testMyNewPage() {
        return Network.communitiesLanding();
    }
}

The code here doesn't cover anything. I have tried a few other things, like adding system.assertEquals(myCurrentControllerTest.testMyNewPage(), myCurrentController.myNewPage());

But I get an error message:

Non static method cannot be referenced from a static context.

I am still very new to Apex tests so any help would be greatly appreciated.

Rather than replicating the behaviour of your controller class in your test class, you'll need to make sure that you use the controller and test the outcomes.

To do this, you'll need to instantiate a new instance of your controller, and then call the methods via that instance. This will look something like this:

    public with sharing class myCurrentControllerTest {
        @IsTest
        public static void testMyNewPage() {

            myCurrentController controller = new myCurrentController();
            PageReference returnedNewPage = controller.myNewPage();

            //Rest of your test logic/assertions here
        }
    }

You might also want to check out some of this resource around Static and Instance (non-static) methods which gives some details about why you're seeing that error: https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_static.htm
