<code class="language-java">import static org.junit.Assert.assertEquals;
import org.junit.Test;

public class AdditionVerification {
   @Test
   public void verifySum() {
      FunctioningClass initiator = new FunctioningClass();
      assertEquals(&quot;The sum of 10 and 5 should be 15&quot;, 15, initiator.sum(10, 5));
   }
}</code>

Here, verifySum is a distinct unit test, specifically created to grant authority to the sum operation in the FunctioningClass. The assertEquals validates the calculation of initiator.sum(10, 5), which is supposed to be 15.

Unit testing tactics possess distinctive attributes, potential, and challenges. There are copious options available, such as renowned frameworks including JUnit for Java, NUnit for .NET, PHPUnit for PHP, and PyUnit for Python.
