Why does Assert.AreEqual(T obj1, Tobj2) fail with identical byte arrays

Question

I have two identical byte arrays in the following segment of code:

    /// 

    ///A test for Bytes
    ///
    [TestMethod()]
            


        

Answer 1

The method Assert.AreEqual under the hood will end up defaulting to Object.Equals() for non-null values. The default implementation of Object.Equals() is referential equality. The 2 arrays are identical value wise but difference reference wise and hence will not be considered equal.
