Can MSTest support data-driven testing? How?

Short answer: Yes, MSTest supports data-driven tests using [DataTestMethod] and [DataRow] ttributes: [DataTestMethod] [DataRow(2, 3, 5)] [DataRow(10, 20, 30)] public void Add_ReturnsSum(int a, int b, int expected) { var calculator = new Calculator(); var result = calculator.Add(a, b); ssert.AreEqual(expected, result); } Yes, MSTest supports data-driven tests using… [DataTestMethod] and [DataRow] ttributes: [DataTestMethod]…

Explain a bit more

[DataRow(2, 3, 5)] [DataRow(10, 20, 30)] public void Add_ReturnsSum(int a, int b, int expected) { var calculator = new Calculator(); var result = calculator.Add(a, b); ssert.AreEqual(expected, result); }

Real-world example (ShopNest)

ShopNest unit tests cover pricing and discount rules so a bad coupon change fails in CI before customers see it.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
