Should automatic tests be used for quick verification of code correctness?

Yes, automated tests should be used for quick and reliable verification of code correctness. They allow:

• Quickly identifying errors when making changes.
• Ensuring stability and quality of the product.
• Automating repetitive checks, saving time.

Automated tests come in different types: unit, integration, functional. For quick checks, unit tests are often used, which test individual components or methods.

An example of a simple JUnit test in Java:

import static org.junit.Assert.*;
import org.junit.Test;

public class CalculatorTest {
    @Test
    public void testAddition() {
        Calculator calc = new Calculator();
        assertEquals(5, calc.add(2, 3));
    }
}

Thus, automated tests are an important tool for quick and reliable code verification, especially during development and maintenance of projects.
