軟體測試 實驗一

標籤：

一、junit、hamcrest和eclemma的安裝。

1.junit和hamcrest在建立了junitHw1工程後在build path裡通過add external jars添加junit－4.12.jar和hamcrest－all－1.3.jar。

2.eclemma在eclipse下點擊help－eclipse marketplace－find－eclemma安裝。

二、編寫Triangle以及TestTriangle1。

1.Triangle－判斷三角形類型

public class Triangle { int[] data;  Triangle(){ data = new int[3]; } public void setData(int[] number){ for(int i = 0;i < data.length;i++){ data[i] = number[i]; } }     public String checkTriangle(){     for(int i = 0;i < data.length;i++){      if(data[i]<=0)      return "Illegal";     }     if(data[0]+data[1]<=data[2]||data[0]+data[2]<=data[1]||data[1]+data[2]<=data[0]){     return "Not triangle";     }     else if(data[0]==data[1]&&data[0]==data[2]){     return "Equilateral";     }     else if(data[0]==data[1]||data[0]==data[2]||data[1]==data[2]){     return "Isosceles";     }     else     return "Scalene";     }}

 2.TriangleTest

import static org.junit.Assert.*;import java.util.Arrays;import java.util.Collection;import org.junit.Test;import org.junit.runner.RunWith;import org.junit.runners.Parameterized;import org.junit.runners.Parameterized.Parameters;@RunWith(Parameterized.class)public class TriangleTest{@Parameterspublic static Collection prepareData(){return Arrays.asList(new Object[][]{{1,3,5,"Not triangle"},{1,2,-3,"Illegal"},{3,4,5,"Scalene"},{2,2,2,"Equilateral"},{2,3,3,"Isosceles"}});}public TriangleTest(int param1,int param2,int param3,String result){this.param1 = param1;this.param2 = param2;this.param3 = param3;this.result = result;}@Testpublic void Test(){triangle.setData(new int[]{param1,param2,param3});assertEquals(result, triangle.checkTriangle());}private int param1,param2,param3;private String result;private static Triangle triangle = new Triangle();}
