軟體測試基礎上機實驗1(三角形的判斷)

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.安裝eclemma

二.編寫Triangle以及Triangletest:

 1.主要代碼（判斷三角形性質）

 1 package example; 2  3 /** 4  * Created by Ev_Eraser on 2016/3/18. 5  */ 6 public class Myclass { 7     public String triangle(int a,int b,int c) { 8         if(a + b < c || a + c < b || b+ c < a) 9             return "notTriangle";10         if(a == b && b == c)11             return "isosceles";12         if(a == b || b == c || a == c)13             return "equilateral";14         else15             return "scalene";16     }17 }

2.測試

package example;import org.junit.After;import org.junit.Before;import org.junit.Test;import org.junit.runner.RunWith;import org.junit.runners.Parameterized;import java.util.ArrayList;import java.util.Arrays;import java.util.Collection;import static org.junit.Assert.*;@RunWith(Parameterized.class)public class MyclassTest {    private Myclass myClass;    private int input1;    private int input2;    private int input3;    private String expected;    public MyclassTest(int input1, int input2,int input3,String expected){        this.input1 = input1;        this.input2 = input2;        this.input3 = input3;        this.expected = expected;    }    @Before    public void setUp() throws Exception {        myClass = new Myclass();    }@Parameterized.Parameters    public static Collection<Object[]> getData(){    return Arrays.asList(new Object[][]{            {2,2,2,"isosceles"},            {2,2,3,"equilateral"},            {2,4,3,"scalene"},            {2,9,2,"notTriangle"}    });    }//    @After//    public void tearDown() throws Exception {////    }    @Test    public void testTriangle() throws Exception {        assertEquals(this.expected, myClass.triangle(input1,input2,input3));    }}

3.測試結果

 

 

四個測試案例都通過，覆蓋率90%
