How do you test code that uses List?

Testing code that uses lists in Java can be done with various approaches, including using JUnit or other testing frameworks. Lists are a crucial part of Java's Collections framework, providing dynamic arrays that can grow as needed. Here’s an example demonstrating how to create a list, add elements, and perform assertions in a test case.

// Example Java code to test a List import org.junit.jupiter.api.Test; import java.util.ArrayList; import java.util.List; import static org.junit.jupiter.api.Assertions.assertEquals; public class ListTest { @Test public void testListAddition() { List list = new ArrayList<>(); list.add("Hello"); list.add("World"); assertEquals(2, list.size()); assertEquals("Hello", list.get(0)); assertEquals("World", list.get(1)); } }
