# MSTest Testing Skill

## Core Patterns

### Basic Test

```csharp
using Microsoft.VisualStudio.TestTools.UnitTesting;

[TestClass]
public class CalculatorTests
{
    private Calculator _calc;

    [TestInitialize]
    public void SetUp() => _calc = new Calculator();

    [TestMethod]
    public void Add_TwoNumbers_ReturnsSum()
    {
        Assert.AreEqual(5, _calc.Add(2, 3));
    }

    [TestMethod]
    [ExpectedException(typeof(DivideByZeroException))]
    public void Divide_ByZero_Throws()
    {
        _calc.Divide(10, 0);
    }
}
```

### Data-Driven Tests

```csharp
[DataTestMethod]
[DataRow(2, 3, 5)]
[DataRow(-1, 1, 0)]
[DataRow(0, 0, 0)]
public void Add_Parameterized(int a, int b, int expected)
{
    Assert.AreEqual(expected, _calc.Add(a, b));
}

[DataTestMethod]
[DynamicData(nameof(GetTestData), DynamicDataSourceType.Method)]
public void Add_DynamicData(int a, int b, int expected)
{
    Assert.AreEqual(expected, _calc.Add(a, b));
}

private static IEnumerable<object[]> GetTestData()
{
    yield return new object[] { 1, 2, 3 };
    yield return new object[] { 10, -5, 5 };
}
```
