Practice on Junit and Eclemma

1.Install Junit and Eclemma

　　1.1. Install Junit

Download necessary JARs packages

技术分享

Click right key on the project – Properties – Java Build Path – Libraries – Add External JARs
Add Junit and harmcrest-all-*

技术分享

　　1.2. Install Eclemma

Help –- Install New Software –Add
Input the name eclemma and the Location with http://update.eclemma.org.

技术分享

Select the eclemma and complete click Next
Reboot the eclipse to complete the installation

2.Using Junit and eclemma

Under src folder, create com.Triangle package
Write Triangle.java

 1 package com.Triangle;
 2 
 3 public class Triangle {
 4     
 5     int a, b, c;
 6     
 7     public Triangle(int x, int y, int z){
 8         a = x;
 9         b = y;
10         c = z;
11     }
12     
13     public String isPositive(){
14         String msg = "";
15         if(a > 0 && b > 0 && c > 0){
16             msg = "positive";
17         }else{
18             if(a <= 0)
19                 msg += "a is negative";
20             if(b <= 0)
21                 msg += "b is negative";
22             if(c <= 0)
23                 msg += "c is negative";
24         }
25         //System.out.println(msg);
26         return msg;
27     }
28     
29     public String isTriangle(){
30         String msg = "";
31         if(a+b > c && a+c > b && b+c > a){
32             msg = "triangle";
33         }else{
34             msg = "not a triangle";
35         }
36         //System.out.println(msg);
37         return msg;
38     }
39     
40     public String isIsosceles(){
41         String msg = "";
42         if(a == b || b == c || c == a){
43             msg = "isosceles";
44         }else{
45             msg = "not isosceles";
46         }
47         //System.out.println(msg);
48         return msg;
49     }
50     
51     public String isEquilateral(){
52         String msg = "";
53         if(a == b & b == c){
54             msg = "equilateral";
55         }else{
56             msg = "not equilateral";
57         }
58         //System.out.println(msg);
59         return msg;
60     }
61     
62     public String judge(){
63         String msg = "";
64         msg = this.isPositive();
65         if(msg.equals("positive")){
66             msg = this.isTriangle();
67             if(msg.equals("triangle")){
68                 msg = this.isIsosceles();
69                 if(msg.equals("isosceles")){
70                     msg = this.isEquilateral();
71                     if(!msg.equals("equilateral")){
72                         return "isosceles";
73                     }
74                 }else{
75                     return "triangle";
76                 }
77             }
78         }
79         return msg;
80     }
81 }

Create new source folder test and create com.Triangle package similarly
Write several classes for test

 1 package com.Triangle;
 2 
 3 import static org.junit.Assert.*;
 4  
 5 import java.util.Arrays;
 6 import java.util.Collection;
 7 
 8 import org.junit.After;
 9 import org.junit.Before;
10 import org.junit.Test;
11 import org.junit.runner.RunWith;
12 import org.junit.runners.Parameterized;
13 import org.junit.runners.Parameterized.Parameters;
14  
15 import com.Triangle.Triangle;
16 
17 @RunWith(Parameterized.class)
18 public class JudgeTest {
19     private int a;
20     private int b;
21     private int c;
22     private String expected;
23     private Triangle triangle;
24     
25     public JudgeTest(int a, int b, int c, String expected){
26         this.a = a;
27         this.b = b;
28         this.c = c;
29         this.expected = expected;
30     }
31     
32     @Before
33     public void setUp(){
34         System.out.println("Before Judge Test");
35         this.triangle = new Triangle(this.a, this.b, this.c);
36     }
37     
38     @After
39     public void tearDown(){
40         System.out.println("After Judge Test");
41     }
42     
43     
44     @Parameters
45     public static Collection<Object[]> getData(){
46         return Arrays.asList(new Object[][]{
47             {3,3,3,"equilateral"},
48             {3,4,3, "isosceles"},
49             {2,3,4, "triangle"},
50             {1,2,3, "not a triangle"},
51             {-1,1,2, "a is negative"},
52             {1,-2,1, "b is negative"},
53             {1,1,-2, "c is negative"}
54         });
55     }
56     
57     @Test
58     public void testAdd(){
59         assertEquals(this.expected, triangle.judge());
60     }
61 }

In order to practice @Runwith(Suite.class), I also write some other test classes

 1 package com.Triangle;
 2 
 3 import static org.junit.Assert.*;
 4

17 @RunWith(Parameterized.class)

19     private int a;
20     private int b;
21     private int c;
22     private String expected;
23     private Triangle triangle;
24     
25     public PositiveTest(int a, int b, int c, String expected){
26         this.a = a;
27         this.b = b;
28         this.c = c;
29         this.expected = expected;
30     }
31     
32     @Before
33     public void setUp(){
34         System.out.println("Before Positive Test");
35         this.triangle = new Triangle(this.a, this.b, this.c);
36     }
37     
38     @After
