JUnit使用示例

package xyz.yearn.sorts;

import org.junit.Test;

import static org.junit.Assert.*;

import java.util.Arrays;

public class FakeSortTest

{

Sort s = new FakeSort();

Comparable[] a = {1,5,1,3,7,1,9,7,7,5,6};

@Test

public void testLess(){

assertTrue (a[0]==a[2]);

assertTrue (s.less(a[0], a[1]));

assertFalse(s.less(a[0], a[2]));

assertFalse(s.less(a[1], a[3]));

}

@Test

public void testExch()

{

Comparable[] b = {1, 2};

Comparable[] c = {2, 1};

assertFalse(Arrays.equals(b, c));

s.exch(b, 0, 1);

assertTrue (Arrays.equals(b, c));

}

@Test

public void testIsSorted()

{

assertFalse(s.isSorted(a));

s.sort(a);

assertTrue (s.isSorted(a));

}

}
