Testing Your Insert Method

Here is given a very limited set of JUnit tests to help determine if implementation is correct. need to add at least 5 more JUnit tests for the insert method that test typical and edge cases. You are welcome (and encouraged) to create more than five JUnit tests, but as long as you create and pass five JUnit tests.

package trees;

import trees.RBTree.Color;//import the enum
import trees.RBTree.Node;//import the Node inner class
import static org.junit.Assert.*;

import java.util.ArrayList;

import org.junit.After;
import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;

public class RBTreeTest {

@BeforeClass
public static void setUpBeforeClass() throws Exception {
}

@AfterClass
public static void tearDownAfterClass() throws Exception {
}

@Before
public void setUp() throws Exception {
}

@After
public void tearDown() throws Exception {
}

@Test
public void testInsert() {
RBTree rootTest = new RBTree();
boolean result = rootTest.insert(1);
Node n = rootTest.root;
assertTrue(result);
assertEquals((Integer)1,n.data);
assertEquals(Color.BLACK,n.color);
}

@Test
public void testInsert1() {
RBTree test = new RBTree();
test.insert(1);
test.insert(0);
test.insert(2);
ArrayList<Integer> actual = new ArrayList<>();
for(Node n: test.inOrder())
actual.add(n.data);

ArrayList<Integer> expected = new ArrayList<>();
for(int i=0;i<3;i++)
expected.add(i);
assertEquals(expected,actual);



}
