Have you created automated tests for C# code during development?

Yes, during development in C#, automatic tests are often created to verify the correctness of the code. Frameworks such as NUnit, MSTest, or xUnit are commonly used.

Here's a simple test example using NUnit:

using NUnit.Framework;

[TestFixture]
public class CalculatorTests
{
    [Test]
    public void Add_TwoNumbers_ReturnsSum()
    {
        var calculator = new Calculator();
        int result = calculator.Add(2, 3);
        Assert.AreEqual(5, result);
    }
}

Automated tests help quickly identify errors and ensure stability when making changes.
