for unit-testing my asp.net MVC web application, I'd like to mock my IGenericRepository (I'm using Moq).

The method that has to be mocked looks like this:

IEnumerable<TEntity> Get(Expression<Func<TEntity, bool>> filter = null, 
        Func<IQueryable<TEntity>, IOrderedQueryable<TEntity>> orderBy = null, string includeProperties = "");

I've already mocked the repository without any problems:

useraccountRepository = new Mock<IGenericRepository<Useraccount>>();

Now I'd like to tell Moq that when the Get method of my interface is called, a list of useraccounts should be returned:

useraccountRepository.Setup(r => r.Get(u => u.Email == useraccount.Email && u.Password == useraccount.Password)).Returns(useraccounts);

I think there is a mistake in my second lambda because this one works:

useraccountRepository.Setup(r => r.Get(null, null, "")).Returns(useraccounts);

But where's my error?

What also works:

useraccountRepository.Setup(r => r.Get(u => u.Email == useraccount.Email 
            && u.Password == useraccount.Password, null, "")).Returns(useraccounts);

It looks like the default parameter values don't apply in my mock. Why is that?

If I use 

useraccountRepository.Setup(r => r.Get(u => u.Email == useraccount.Email 
            && u.Password == useraccount.Password, null, "")).Returns(useraccounts);

anyway, then the method in my controller throws an exception when the Get message is called:

private bool validateUser(Useraccount useraccount)
    {
        try
        {
            Useraccount useraccountLogin = UnitOfWork.UseraccountRepository.Get(
                u => u.Email == useraccount.Email && u.Password == useraccount.Password).Single<Useraccount>();

            return (useraccountLogin != null);
        }
        catch (Exception exc)
        {
            return false;
        }            
    }

Where are my mistakes?

Thank you in advance. Michael
