　　参数化测试，SquareTest.java:
1 import static org.junit.Assert.*;
2
3 import java.util.Arrays;
4 import java.util.Collection;
5
6 import org.junit.Before;
7 import org.junit.Test;
8 import org.junit.runner.RunWith;
9 import org.junit.runners.Parameterized;
10 import org.junit.runners.Parameterized.Parameters;

12 @RunWith(Parameterized.class)
13 public class SquareTest {
14     private static Calculator calculator = new Calculator();
15     private int param;
16     private int result;
17

19     @Parameters
20     public static Collection data(){
21         return Arrays.asList(new Object[][]{
22                 {2，4}，
23                 {0，0}，
24                 {-3，9}，
25         });
26     }
27
28     //构造函数，对变量进行初始化
29     public SquareTest(int param，int result){
30         this.param = param;
31         this.result = result;
32     }
33
34     @Test
35     public void square(){
36         calculator.square(param);
37         assertEquals(result，calculator.getResult());
38     }

　　打包测试，AllCalculatorTests.java:
1 import org.junit.runner.RunWith;
2 import org.junit.runners.Suite;
3
4 @RunWith(Suite.class)
5 @Suite.SuiteClasses({
6     CalculatorTest.class，
7     SquareTest.class
