Is there an in-memory provider for Entity Framework?

Question

I am unit testing code written against the ADO .NET Entity Framework. I would like to populate an in-memory database with rows, and make sure that my code retrieves them pro

Answer 1

I am not familiar with Entity Framework and the ObjectQuery class but if the Include method is virtual you can mock it like this:

// Arrange
var customerSourceStub = MockRepository.GenerateStub>();
var customers = new Customer[] 
{
    // Populate your customers as if they were coming from DB
};
customerSourceStub
    .Stub(x => x.Include("Order"))
    .Return(customers);
var sut = new CustomerService(customerSourceStub);

// Act
var actual = sut.GetCustomerById(5);

// Assert
Assert.IsNotNull(actual);
Assert.AreEqual(5, actual.Id);
