Title:
  NUnit's logic for comparing arrays - use Comparer<T[]> if it is
  provided.

Status in NUnit Test Framework:
  Fix Released
Status in NUnit V2 Test Framework:
  Fix Released

Bug description:
  In the following code snippet, NUnit uses passed comparer as elements'
  comparer, which prevents us from treating array types just like any
  other data types in unit tests. The workaround is to check for
  equality in the following way - Assert.AreEqual(0,
  comparer.Compare(expected, actual))).

  [TestFixture] 
  public class NUnitFeatures 
  { 
     [Test] 
     public void CustomArrayComparison() 
     { 
        Assert.That(new[] { 1 }, Is.EqualTo(new[] { 1 }).Using(new IntArrayComparer())); 
     } 

     class IntArrayComparer : IComparer<int[]> 
     { 
        public int Compare(int[] x, int[] y) { return 0; }  // just a stub
     } 
  }
