NUnit: Dictionary Assert

I want a one liner, in NUnit, that asserts whether two dictionary are the same. i.e., I want a concise version of the below code:

public static void DictionaryAssert<T, U>(Dictionary<T, U> dictionaryResult, Dictionary<T, U> expectedRes开发者_开发技巧ult)
{
    Assert.AreEqual(dictionaryResult.Count, expectedResult.Count);
    foreach (var aKey in expectedResult.Keys)
    {
        Assert.AreEqual(expectedResult[aKey], dictionaryResult[aKey]);
    }
}

Surely it isn't so difficult, but I can't find the reference, any idea?

Have a look at CollectionAssert.AreEquivalent. This will assert that the two dictionaries have the same contents, but are not necessarily the same instance.

Try using CollectionAssert.AreEqual or CollecitonAssert.AreEquivalent.

Both will compare the collection's items (rather than the collection's reference), but as discussed before, The difference is the item's order within the collections:

• AreEqual - The collections must have the same count, and contain the exact same items in the same order.
• AreEquivalent - The collections must contain the same items but the match may be in any order.

You can write framework agnostic asserts using a library called Should. It also has a very nice fluent syntax which can be used if you like fluent interfaces. I had a blog post related to the same.
