Protected members

Mockolate allows you to set up and verify protected virtual members on class mocks.

Protected members can be set up, raised, and verified just like instance members, but through the Mock.SetupProtected, Mock.RaiseProtected, and Mock.VerifyProtected properties:

Example

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

ChocolateDispenser sut = ChocolateDispenser.CreateMock();

Setup​

// Setup protected method
sut.Mock.SetupProtected.DispenseInternal(
    It.Is("Dark"), It.IsAny<int>())
    .Returns(true);

// Setup protected property
sut.Mock.SetupProtected.InternalStock.InitializeWith(100);

Notes:

  • Protected members can be set up and verified just like public members.
  • All setup options (.Returns(), .Throws(), .Do(), .InitializeWith(), etc.) work with protected members.

Verification​

// Verify protected method was invoked
sut.Mock.VerifyProtected.DispenseInternal(
    It.Is("Dark"), It.IsAny<int>()).Once();

// Verify protected property was read
sut.Mock.VerifyProtected.InternalStock.Got().AtLeastOnce();

// Verify protected property was set
sut.Mock.VerifyProtected.InternalStock.Set(It.Is(100)).Once();

// Verify protected indexer was read
sut.Mock.VerifyProtected[It.Is(0)].Got().Once();

// Verify protected indexer was set
sut.Mock.VerifyProtected[It.Is(0)].Set(It.Is(42)).Once();

Note:

  • All verification options (argument matchers, count assertions) work the same for protected members as for public members.
