Put Arrange and Act in SetupContext method and test all results in each test method: [TestFixutre] public class WhenAddingValueToTheContainer() { [TestFixtureSetup] SetupContext() { // Create sample data // Act on it } [Test] public void ShouldContainOneElement() { Assert.That(_container.Items, Has.Count.EqualTo(1)); } [Test] public void ShouldHaveTotalValueEqualTo100() { Assert.That(_container.TotalValue, Is.EqualTo(100)); } AAA unit test patern is very good on simple object, on more complex it is sometimes better to create one test class for each context of tested class.
