Unit Test with input parameter

Question

How to call method as a parameter into TestCase attribute NUnit?

Like we can write: [TestCase(1, 2, 3)]

How to call a function like below?: [TestCase(SomeFunction(), 1, 2, 3)]

Answer 1

You can try TestCaseSource attribute and use static method for your use case.

    public static IEnumerable<EditModel> Generator()
    {
        // You can also call methods here
        yield return new EditModel();
    }

    [Test]
    [TestCaseSource(nameof(Generator))]
    public void DoSomething(EditModel model)
    {
        Console.WriteLine($"{model.commentText}");
    }
