How do you evaluate the role and importance of automated tests in the software development process?

Automated tests play a key role in ensuring software quality. They allow for quick and reliable verification of code correctness when making changes, reducing the risk of regressions. They are especially important in frequent releases and in team development, where manual testing becomes costly and error-prone.

For junior and middle developers, automated tests help better understand requirements and code structure, as well as speed up the debugging process. An example in C# is writing a unit test using NUnit:

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

Thus, test automation increases product stability and team efficiency.
