Protected Methods

Overrideable protected members of the class can be impersonated just like other overridable class members.

Target type used in examples:

Example

using Imposter.Abstractions;

[assembly: GenerateImposter(typeof(Imposter.Tests.Docs.Methods.Protected.MyService))]

namespace Imposter.Tests.Docs.Methods.Protected
{
    public class MyService
    {
        protected virtual int ProtectedAdd(int value) => value * 2;
        public virtual int InvokeProtected(int value) => ProtectedAdd(value);
    }
}

Example

Example

// Class target with a protected virtual method and a public wrapper that calls it
[assembly: GenerateImposter(typeof(MyService))]

public class MyService
{
    protected virtual int ProtectedAdd(int value) => value * 2;
    public virtual int InvokeProtected(int value) => ProtectedAdd(value);
}

var imposter = new MyServiceImposter();

// Arrange the protected method directly on the imposter
imposter.ProtectedAdd(Arg<int>.Is(5)).Returns(42);

var service = imposter.Instance();
service.InvokeProtected(5).ShouldBe(42);
