This is a JUnit test for ArrayList_rc1. To use this file, follow these steps.

1. Create a new "JUnit Test Case" by right-click on the project, choose new, choose JUnit Test Case. A dialog will appear.
2. Choose new JUnit 4 test.
3. In "Name", enter TestArrayList_rc1.
4. In "Class under test", enter ArrayList_rc1.
5. Click finish.
6. Replace the content of the newly created file with the following code.

[code lang="java"] import static org.junit.Assert.*;

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

public class TestArrayList_rc1 { private ArrayList_rc1 list;

@Before
public void setUp() throws Exception {
    list = new ArrayList_rc1(5);
}

@After
public void tearDown() throws Exception {
    list = null;
}

@Test
public void testRemove() {
    list.add(\"Obj1\");
    list.add(\"Obj2\");
    list.add(\"Obj3\");
    list.add(\"Obj4\");
    list.add(\"Obj5\");
    
    assertEquals(0, list.indexOf(\"Obj1\"));
    assertEquals(1, list.indexOf(\"Obj2\"));
    assertEquals(-1, list.indexOf(\"hahaha\"));
    
    list.remove(\"Obj9\");
    
    assertEquals(5, list.size());
    
    list.remove(\"Obj2\");
    
    assertEquals(\"Obj1\", list.get(0));
    assertEquals(\"Obj3\", list.get(1));
    assertEquals(4, list.size());
}

@Test
public void testIndexOf() {
    list.add(\"Obj1\");
    list.add(\"Obj2\");
    list.add(\"Obj3\");
    
    assertEquals(0, list.indexOf(\"Obj1\"));
    assertEquals(1, list.indexOf(\"Obj2\"));
    assertEquals(-1, list.indexOf(\"hahaha\"));
}

@Test
public void testGet() {
    list.add(\"Obj1\");
    list.add(\"Obj2\");
    list.add(\"Obj3\");
    
    assertEquals(\"Obj1\", list.get(0));
    assertEquals(\"Obj2\", list.get(1));
    assertEquals(\"Obj3\", list.get(2));
}

@Test
public void testSet() {
    list.add(\"Obj1\");
    list.add(\"Obj2\");
    list.add(\"Obj3\");
    
    assertEquals(\"Obj1\", list.get(0));
    assertEquals(\"Obj2\", list.get(1));
    assertEquals(\"Obj3\", list.get(2));
    
    list.set(1,\"Obj9\");
    assertEquals(\"Obj9\", list.get(1));
    assertEquals(3,list.size());
