Question

I have the following test which is failing:

[TestCase]
public void Should_order_numeric_suffix()
{
    var names = new List<string>
                    {
                        "Buisness Unit 7",
                        "Business Unit 1",
                        "Buisness Unit 3",
                        "Business Unit 6",
                        "Business Unit 4",
                        "Buisness Unit 2",
                        "Business Unit 5"
                    };

    List<string> ordered = names.OrderBy(x => x).ToList();

    Assert.That(ordered[0], Is.EqualTo("Business Unit 1"));
}

The actual order of the ordered List is:

Business Unit 2
Business Unit 3
Business Unit 7
Business Unit 1
Business Unit 4
Business Unit 5
Business Unit 6

Obviously it is ordering alphabetically correctly but I expected the numeric suffix to be ordered also.

Answer 1

You have typos in your list, some entries spell “Buisness” instead of “Business”… and “Buisness” comes before “Business” in alphabetical order
