How do I put new List {1} in an NUNIT TestCase?

Question

I have the method:

public static int Add(List numbers)
    {
        if (numbers == null || numbers.Count == 0)
            return 0;

        if          


        

Answer 1

My solution is simpler, I just use params. I hope this works for you!

[TestCase(1, 1)]
[TestCase(10, 5, 1, 4)]
[TestCase(25, 3, 5, 5, 12)]
public void Linq_Add_ShouldSumAllTheNumbers(int expected, params int[] numbers)
{
    var result = CalculatorLibrary.CalculatorFunctions.Add(numbers);
    Assert.AreEqual(expected, result);
}
