lease help me with this problem. Thank you Testing Your MergeSorter: I have given you a very limited set of JUnit tests to help determine if your implementation is correct. You need to add at least 5 more JUnit tests for the mergeSort method that test typical and edge cases. You are welcome to create more than five JUnit tests, but as long as you create and pass five JUnit tests package divideandconquer; import static org.junit.Assert.*; import org.junit.Before; import org.junit.BeforeClass; import org.junit.Test; public class MergeSorterTest { @BeforeClass public static void setUpBeforeClass() throws Exception { } @Before public void setUp() throws Exception { } @Test public void test() { int[] nums = new int[]{4,3,2,1}; int[] sorted = new int[] {1,2,3,4}; MergeSorter.mergeSort(nums); assertArrayEquals(sorted,nums); }

Testing Your MergeSorter:
I have given you a very limited set of JUnit tests to help determine if your implementation is correct. You need to add at least 5 more JUnit tests for the mergeSort method that test typical and edge cases. You are welcome to create more than five JUnit tests, but as long as you create and pass five JUnit tests
package divideandconquer;
import static org.junit.Assert.*;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
public class MergeSorterTest {
@BeforeClass
public static void setUpBeforeClass() throws Exception {
}
@Before
public void setUp() throws Exception {
}
@Test
public void test() {
int[] nums = new int[]{4,3,2,1};
int[] sorted = new int[] {1,2,3,4};
MergeSorter.mergeSort(nums);
assertArrayEquals(sorted,nums);
}
}
To add at least 5 more JUnit tests for the mergeSort
method, you can test the following cases:
- An array with duplicated elements. This test will check if the implementation can handle arrays with duplicated elements and sort them correctly.
@Test
public void testDuplicatedElements() {
int[] nums = new int[]{4,3,3,2,1};
int[] sorted = new int[] {1,2,3,3,4};
MergeSorter.mergeSort(nums);
assertArrayEquals(sorted,nums);
}
