You could use the ShouldContainOnly(IEnumerable<T>) extension method.

So if you have 2 lists, listA and listB use:

listA.ShouldContainOnly(listB)

...but check that your objects implement `Equals` appropriately. Machine.Specifications looks for `IComparable`, `IComparable`, `IEquatable`, and then uses `Comparer.Default`. – Roger Lipscombe Nov 28 '11 at 15:28
will that include order of the items check? – Sly Nov 12 '15 at 09:18

If the order of the items in the list doesn't matter, you would use

listA.ShouldContainOnly(listB); // both lists must have exactly the same items
listA.ShouldContain(listB);     // listA must at least contain the items of listB

If the order of the items matters, you can use

listA.ShouldEqual(listB);
