软件测试第一次上机

一.junit、hamcrest和eclemma的安装：

1.junit和hamcrest在新建了junitHw1工程后在build path里通过add external jars添加junit－4.12.jar和hamcrest－all－1.3.jar。

2.eclemma在eclipse下点击help－eclipse marketplace－find－eclemma安装。

二.编写Triangle以及Triangletest:

1.判断三角形：

package example;

/**
 * Created by Ev_Eraser on 2016/3/18.
 */
public class Myclass {
    public String triangle(int a,int b,int c) {
        if(a + b < c || a + c < b || b+ c < a)
            return "notTriangle";
        if(a == b && b == c)
            return "isosceles";
        if(a == b || b == c || a == c)
            return "equilateral";
        else
            return "scalene";
    }
}

2.测试:

package example;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;

import java.util.Arrays;
import java.util.Collection;

import static org.junit.Assert.assertEquals;

@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));
    }
}
