How do I verify that the expected array is the actual array in MSTest?

Question

The following method fails:

[TestMethod] public void VerifyArrays() {     int[] actualArray = { 1, 3, 7 };     Assert.AreEqual(new int[] { 1, 3, 7 }, actualArray); } 

How do I make it pass without iterating over the collection?

Answer 1

Microsoft has provided a helper class CollectionAssert.

[TestMethod] public void VerifyArrays() {     int[] actualArray = { 1, 3, 7 };     CollectionAssert.AreEqual(new int[] { 1, 3, 7 }, actualArray); } 

Answer 2

You can use the Enumerable.SequenceEqual() method.

[TestMethod] public void VerifyArrays() {     int[] actualArray = { 1, 3, 7 };     int[] expectedArray = { 1, 3, 7 };      Assert.IsTrue(actualArray.SequenceEqual(expectedArray)); }
