Unit Test Comparing Results of List

Hi Experts!

Thanks for reading this.

For MS Test project how would you compare that the two List of SomeModel have the same contents?

In the Test Method we have this:

List<SomeModel> expected = CreateExpectedSomeModel();
List<SomeModel> actual;

//If this was an array would use SequenceEqual
Assert.IsTrue(expected.SequenceEqual(actual));

TIA!

Use the CollectionAssert class. You can use the AreEqual method to check for the same elements, in the same order; you can use the AreEquivalent method to check for the same elements, but in any order.

Thanks kaufmed; I'll try it later .. I'm really heading out now ....

Tried AreEqual and this came up:

CollectionAssert.AreEqual failed. (Element at index 0 do not match.

Tried AreEquivalent failed and this came up:

CollectionAssert.AreEquivalent failed. The expected collection contains 1 occurrence(s) of <Blah.DomainClasses.SomeModel>. The actual collection contains 0 occurrence(s).

Manually inspected the contents of expected and actual (setting breakpoint) and the contents are the same.

Dumped contents of expected and actual to separate db tables and the contents are the same.

If it's any help here are the contents from the Intermediate windows during debugging:

Any ideas?

Even if we do this:

List<SomeModel> expected = CreateExpectedSomeModel();
List<SomeModel> actual = CreateExpectedSomeModel();

And try to compare with either:

CollectionAssert.AreEquivalent(expected, actual);
CollectionAssert.AreEqual(expected, actual);

we still get the same errors.
