Protected members

Class mocks can also set up and verify protected virtual and abstract members. They work like public members, but are reached through Mock.SetupProtected, Mock.RaiseProtected and Mock.VerifyProtected:

public abstract class ChocolateDispenser
{
    protected virtual bool DispenseInternal(string type, int amount) => true;
    protected virtual int InternalStock { get; set; }
    protected virtual int this[int slot] { get => 0; set { } }
}

ChocolateDispenser dispenser = ChocolateDispenser.CreateMock();

Setup

// Set up a protected method
dispenser.Mock.SetupProtected.DispenseInternal("Dark", It.IsAny<int>())
    .Returns(true);

// Set up a protected property
dispenser.Mock.SetupProtected.InternalStock.InitializeWith(100);

All setup options of methods, properties and indexers are available.

Verification

// A protected method was called
dispenser.Mock.VerifyProtected.DispenseInternal("Dark", It.IsAny<int>()).Once();

// A protected property was read and set
dispenser.Mock.VerifyProtected.InternalStock.Got().AtLeastOnce();
dispenser.Mock.VerifyProtected.InternalStock.Set(100).Once();

// A protected indexer was read and set
dispenser.Mock.VerifyProtected[0].Got().Once();
dispenser.Mock.VerifyProtected[0].Set(42).Once();

All verification options work the same as for public members.
