Test Framework

MSTest is the standard test framework.

MSTest Conventions

Naming

• Test project: <Project>.Tests
• Test class: <ClassUnderTest>Tests
• Test method: <MethodName>_<Scenario>_<ExpectedResult>

Structure (Arrange-Act-Assert)

[TestClass]
public class OrderServiceTests
{
    [TestMethod]
    public void CalculateTotal_WithValidItems_ReturnsCorrectSum()
    {
        // Arrange
        var service = new OrderService();
        var items = new List<OrderItem> { /* ... */ };

        // Act
        var result = service.CalculateTotal(items);

        // Assert
        Assert.AreEqual(expected, result);
    }

    [TestMethod]
    [ExpectedException(typeof(ArgumentNullException))]
    public void CalculateTotal_WithNullItems_ThrowsArgumentNull()
    {
        // Arrange
        var service = new OrderService();

        // Act
        service.CalculateTotal(null);
    }

    [DataTestMethod]
    [DataRow(0, 0)]
    [DataRow(1, 10)]
    [DataRow(5, 50)]
    public void CalculateTotal_WithItemCount_ReturnsExpected(int count, decimal expected)
    {
        // Arrange & Act & Assert
    }
}

Test Categories

What to Test

Must Test

• All public methods
• Edge cases (null, empty, boundary values)
• Error/exception paths
• Business logic and calculations
• Data validation rules
• State transitions

Should Test

• Integration points (with mocks/fakes)
• Configuration handling
• Mapping/transformation logic

Test Quality Rules

1. One assertion concept per test — test one behavior
2. No test interdependence — tests must run in any order
3. No hardcoded paths or connection strings — use configuration
4. Use test builders for complex object setup
5. Mock external dependencies — don't call real services in unit tests
6. Test names must describe behavior — readable without seeing code
