Понятные тесты...

Да, опять тесты...

Вот такие тесты сейчас я нахожу очень понятными (в таком формате я и чужие тесты понимаю, и свои многолетней давности):

    [TestFixture]
    public class RibbonFormTests {
        [Test]
        public void RibbonForm_ControlsAddRibbon_SizeSet700x700_Show() {
            using(RibbonForm form = new RibbonForm()) {
                form.Controls.Add(new RibbonControl());
                form.Size = new Size(700, 700);
                form.Show();
                Application.DoEvents();
                Assert.AreEqual(700, form.DesktopBounds.Width);
                Assert.AreEqual(700, form.DesktopBounds.Height);
            }
        }
