I have a class with a method that returns an object of type User
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)
// ...
};
}
// ..
}
User
is a domain object. Note the Id
property with setter as protected:
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; }
}
Id is protected because it is generated by the database.
Test project
In my Test project I have a Fake repository with a method Store
to save/update the object:
public void Store(T obj)
{
if (obj.Id > 0)
_context[obj.Id] = obj;
else
{
var generateId = _context.Values.Any() ? _context.Values.Max(p => p.Id) + 1 : 1;
var stubUser = Mock.Get<T>(obj); // In test, will always mock
stubUser.Setup(s => s.Id).Returns(generateId);
_context.Add(generateId, stubUser.Object);
}
}
In CustomMembershipProvider
I have public override MembershipUser CreateUser
method that calls the GetUser
to create a User
.
This way, all I have to do is mock the GetUser
method so that the repository can generate the Id
var membershipMoq = new Mock<CustomMembershipProvider>();
membershipMoq.CallBase = true;
membershipMoq
.Setup(p => p.GetUser(It.IsAny<string>(), It.IsAny<string>(), It.IsAny<string>(), It.IsAny<bool>()))
.Returns<string, string, string, bool>( (username, password, email, isAproved) => {
var moqUser = new Mock<User>();
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;
Problem
In theory everything is correct. When CreateUser
call 'GetUser' to create a user, the user will return Mock filled;
[TestMethod]
public void CreateUser_deve_criar_usuario_no_repositorio()
{
// Act
MembershipCreateStatus status;
var usr = _membershipProvider.CreateUser(
_fixture.Create<string>(),
_fixture.Create<string>(),
_fixture.Create<string>(),
null, null, true, null,
out status);
// usr should have name, email password filled. But not!
// Assert
status.Should().Be(MembershipCreateStatus.Success);
}
The problem is that Email, Name, Password are empty (with default values)!
Best Answer
The way you prepare the mocked user is the problem.
will not set the name, unless you have setup the mock properly. Try this before assigning values to properties:
This method will prepare all properties on the mock to be able to record the assigned value, and replay it later (i.e. to act as real property).
You can also use SetupProperty() method to set up individual properties to be able to record the passed in value.
Another approach is:
