N Unit Alphabetical Order Assertion

I have a search box on a website that returns search results, based on keyword (storing these as a list in c#)

There are filter options which I need to test, one of which is product name A-Z.

When this is selected, the search results should be sorted accordingly.

Is there anyway to assert that this has been done against the list with N Unit ?

If you just need to ensure they are sorted, use the constraint assertion syntax. It's as simple as this:

string[] yourActualSearchResults = new string[] ( "alpha", "beta", "gamma" );

Assert.That(yourActualSearchResults, Is.Ordered);

Yes, you can use CollectionAsserts which succeed if the two collections contain the same objects, in the same order. Of course this requires you to have expected collection sorted, like:

var expected = new[] { "A", "B", "C" };
var actual = ...
CollectionAssert.AreEqual(expected, actual);

Similar effect can be achieved with constraint model and Enumerable.SequenceEqual:

var expected = new[] { "A", "B", "C" };
var actual = ...
Assert.That(expected.SequenceEqual(actual), Is.True);

But this will have less localized failure message (true vs false), rather than pointing where collections differ (which is the case for CollectionAssert).
