C# – Can’t get Latest Rhino Mocks to work

crhino-mocks

I don't get it – I've looked at the documentation, and I can't see what's wrong with this code:

var mocks = new MockRepository();
var repository = mocks.StrictMock<IRecipeRepository>();
IList<Recipe> recipes = new List<Recipe>();
recipes.Add(new Recipe { ID = 1, Name = "Fish" });
recipes.Add(new Recipe { ID = 2, Name = "Chips" });

// This line doesn't compile:
Expect.Call(() => repository.All()).Return(recipes);

This is Rhino Mocks v3.6, for which I can only assume there are breaking changes that aren't in any of the documentation yet.

Never mind - I fixed it:

var mocks = new MockRepository();
var repository = mocks.StrictMock<IRecipeRepository>();
IList<Recipe> recipes = new List<Recipe>();
recipes.Add(new Recipe { ID = 1, Name = "Fish" });
recipes.Add(new Recipe { ID = 2, Name = "Chips" });

Expect.Call(repository.All()).Return(recipes);

It is late, I guess I couldn't see the wood for the trees. :)

C# – How to get the index of the current iteration of a foreach loop

Ian Mercer posted a similar solution as this on Phil Haack's blog:

foreach (var item in Model.Select((value, i) => new { i, value }))
{
    var value = item.value;
    var index = item.i;
}

This gets you the item (item.value) and its index (item.i) by using this overload of LINQ's Select:

the second parameter of the function [inside Select] represents the index of the source element.

The new { i, value } is creating a new anonymous object.

Heap allocations can be avoided by using ValueTuple if you're using C# 7.0 or later:

foreach (var item in Model.Select((value, i) => ( value, i )))
{
    var value = item.value;
    var index = item.i;
}

You can also eliminate the item. by using automatic destructuring:

<ol>
foreach ((MyType value, Int32 i) in Model.Select((value, i) => ( value, i )))
{
    <li id="item_@i">@value</li>
}
</ol>

What are the differences between mocks and stubs on Rhino Mocks

As per this

... Put simply there is a difference between Mock and Stub objects and RhinoMocks recognizes that allowing us to write tests that better state their purpose.

Mock objects are used to define expectations i.e: In this scenario I expect method A() to be called with such and such parameters. Mocks record and verify such expectations.

Stubs, on the other hand have a different purpose: they do not record or verify expectations, but rather allow us to “replace” the behavior, state of the “fake”object in order to utilize a test scenario ...
