C# unit test using Moq verify property has been set

C# > Unit test > Moq > Verify property has been set

SetupSet : Specifies a setup on the mocked type for a call to a property setter.

VerifySet : Verifies that a property has been set on the mock, regardless of its value.

Example

using System;

namespace UnitTestProject1

{

    public interface Interface1

    {

        int Id { get; set; }

    }

}

using Microsoft.VisualStudio.TestTools.UnitTesting;

using Moq;

namespace UnitTestProject1

{

    [TestClass]

    public class UnitTest1

    {

        [TestMethod]

        public void TestMethod1()

        {

            var mocker = new Mock<Interface1>();

            mocker.SetupSet(x => x.Id = 1);

            mocker.Object.Id = 1;

            mocker.VerifySet(x => x.Id);

        }

    }

}

C# Generic Interface Example

C# > Generics > Generic Interface 

Example

class Serializer1 { public string Name { get; set; } };

class Serializer2 { public string Name { get; set; } };

interface GenericSerializer<T>

{

      string Name(T tValue);

}

class Serializer<T>: GenericSerializer<T>

{

public string Name(T tValue)

        {

            var prop = tValue.GetType().GetProperty("Name");

            return prop.GetValue(tValue, null) as string;

        }

}

Serializer1 s1 = new Serializer1() { Name = "Serializer1" };

Serializer2 s2 = new Serializer2() { Name = "Serializer2" };

Serializer<Serializer1> serializer1 = new Serializer<Serializer1>();

string name1 = serializer1.Name(s1);

Serializer<Serializer2> serializer2 = new Serializer<Serializer2>();

string name2 = serializer2.Name(s2);
