    copied!<p>I have a class with a method that returns an object of type <code>User</code></p> <pre><code>public class CustomMembershipProvider : MembershipProvider { public virtual User GetUser(string username, string password, string email, bool isApproved) { return new User() { Name = username ,Password = EncodePassword(password) ,Email = email ,Status = (isApproved ? UsuarioStatusEnum.Ativo : UsuarioStatusEnum.ConfirmacaoPendente) // ... }; } // .. } </code></pre> <p><code>User</code> is a domain object. Note the <code>Id</code> property with <strong>setter as protected</strong>:</p> <pre><code>public class User : IAuditable, IUser { public virtual int Id { get; protected set; } public virtual string Name { get; set; } public virtual string Email { get; set; } public virtual UsuarioStatusEnum Status { get; set; } public virtual string Password { get; set; } } </code></pre> <p><em>Id is protected because it is generated by the database.</em></p> <h2>Test project</h2> <p>In my Test project I have a Fake repository with a method <code>Store</code> to save/update the object:</p> <pre><code>public void Store(T obj) { if (obj.Id &gt; 0) _context[obj.Id] = obj; else { var generateId = _context.Values.Any() ? _context.Values.Max(p =&gt; p.Id) + 1 : 1; var stubUser = Mock.Get&lt;T&gt;(obj); // In test, will always mock stubUser.Setup(s =&gt; s.Id).Returns(generateId); _context.Add(generateId, stubUser.Object); } } </code></pre> <p>In <code>CustomMembershipProvider</code> I have <code>public override MembershipUser CreateUser</code> method that calls the <code>GetUser</code> to create a <code>User</code>.<br> This way, all I have to do is mock the <code>GetUser</code> method so that the repository can generate the <code>Id</code></p> <pre><code>var membershipMoq = new Mock&lt;CustomMembershipProvider&gt;(); membershipMoq.CallBase = true; membershipMoq .Setup(p =&gt; p.GetUser(It.IsAny&lt;string&gt;(), It.IsAny&lt;string&gt;(), It.IsAny&lt;string&gt;(), It.IsAny&lt;bool&gt;())) .Returns&lt;string, string, string, bool&gt;( (username, password, email, isAproved) =&gt; { var moqUser = new Mock&lt;User&gt;(); moqUser.Object.Name = username; moqUser.Object.Password = password; moqUser.Object.Email = email; moqUser.Object.Status = (isAproved ? UsuarioStatusEnum.Ativo : UsuarioStatusEnum.ConfirmacaoPendente); return moqUser.Object; }); _membershipProvider = membershipMoq.Object; </code></pre> <h2>Problem</h2> <p>In theory everything is correct. When <code>CreateUser</code> call 'GetUser' to create a user, the user will return Mock filled;</p> <pre><code>[TestMethod] public void CreateUser_deve_criar_usuario_no_repositorio() { // Act MembershipCreateStatus status; var usr = _membershipProvider.CreateUser( _fixture.Create&lt;string&gt;(), _fixture.Create&lt;string&gt;(), _fixture.Create&lt;string&gt;(), null, null, true, null, out status); // usr should have name, email password filled. But not! // Assert status.Should().Be(MembershipCreateStatus.Success); } </code></pre> <p>The problem is that Email, Name, Password are empty (with default values)!</p> <p><img src="https://i.stack.imgur.com/WTpee.jpg" alt="enter image description here"></p>
