Variable is not visible in test class

Question

Can any one help me on this Error as **Variable is not visible** in a test class.Any help very much appreciated.

Code :

 public with sharing class InvoiceController {
 List<wrapperClass> appointmentList {get;set;}//These three lines are not 
 List<wrapperClass> appointmentList1 {get;set;} //covered in test class
 public list<string> address{get;set;}//

}

Test Class :

InvoiceController icwc = new InvoiceController(sc);
    icwc.appointmentList=icwc.getappointmentList();
    icwc.appointmentList1=icwc.getappointmentList1();

The system throws an Error as :

Variable is not visible: appointmentList 
 icwc.appointmentList=icwc.getappointmentList();

Similarly for the other

Variable is not visible: appointmentList1 
 icwc.appointmentList1=icwc.getappointmentList1();

Answer 1

That's because you did not label your properties as public (you don't have an access modifier at all) in your class. I am going under the assumption that you wanted these List to be accessible publicly.

If you do this:

public List<wrapperClass> AppointmentList { get;set; }
public List<wrapperClass> AppointmentList1 { get;set; }

they will be accessible in your test class.

If it is not meant to be visible i.e. private, you should specify it as such with the keyword private and you can use the @TestVisible annotation as suggested. However this should be a last resort!

Before you do that however, you should do the following:

• Try to figure out if there is a way to populate it in your test method
• See if the property is actually necessary
• Find another way to initialize the property in your class so you code is actually testable

If you cannot find a way to populate your private properties, after you have exhausted all options, then you can use the @TestVisible annotation.

Here would be an example:

@TestVisible private List<wrapperClass> AppointmentList { get;set; }
@TestVisible private List<wrapperClass> AppointmentList1 { get;set; }

Use TestVisible annotations for private class variables to be accessed in test classes. Please refer https://www.salesforce.com/us/developer/docs/apexcode/Content/apex_classes_annotation_testvisible.htm
