《软件测试》实验报告

一、实验目的

Junit最初是有ErichGamma 和KentBeck编写的一个回归测试框架(regressiontestingframework),为单元测试(UnitTest)的支持框架,用来编写和执行重复性的测试,即所谓的白盒测试,Junit是一套框架,继承TestCase类,就可以用Junit进行自动测试。

本次实验就是用Junit框架编写测试用例,进行自动化的白盒测试。

实验包括三道题目:

1〕DoubleLinkList

2〕NextDay

3〕Vector

二、实验要求

1〕实验环境:

JavaJDK1.7,eclipse;

2〕在慕测平台提交实验结果;

3〕提交一份Word版实验报告到ftp,报告内容需包含实验代码;

4〕本次实验提交截止日期为10月28号晚12点〔写周六晚12点〕。

三、实验设备〔环境〕

JDK1.7

EclipseLuna

Eclemma

四、实验内容与结果

1〕DoubleLinkList

测试类中定义双向链表,考虑清楚其分支情况;

代码:

importstatic org.junit.Assert.*;

import;

import java.util.ArrayList;

import java.util.Collection;

import org.junit.Test; //双向链表,拥有增加结点,按索引搜寻

 

publicclass DoubleLinkedListTest{

Test

publicvoid test(){

DoubleLinkedList doubleLinkedList1 = new DoubleLinkedList();

doubleLinkedList1.clear();

Object object = new Object();

doubleLinkedList1.indexOf(object);

doubleLinkedList1.add(object);

doubleLinkedList1.indexOf(object);

Collection collection = new ArrayList();

collection.add("1");

collection.add("2");

collection.add("3");

 

DoubleLinkedList doubleLinkedList = new DoubleLinkedList(collection);

//

// assertEquals(true,actual);

assertEquals(true, doubleLinkedList.contains("1"));

assertEquals(false, doubleLinkedList.contains(null));

assertEquals(3, doubleLinkedList.size());

doubleLinkedList.add("4");

doubleLinkedList.remove("4");

doubleLinkedList.remove("");

String s = null;

doubleLinkedList.remove(s);

doubleLinkedList.add(null);

doubleLinkedList.remove(s);

 

assertEquals("1", doubleLinkedList.get(0));

doubleLinkedList.add(0, "999");

doubleLinkedList.add(4, "999");

doubleLinkedList.remove(4);

 

try {

doubleLinkedList.entry(-1);

} catch (Exception e){

// TODO:

handleexception

}

try {

doubleLinkedList.entry(5);

} catch (Exception e){

// TODO:

handleexception

}

doubleLinkedList.add(null);

assertEquals(4, doubleLinkedList.indexOf(null));

assertEquals(0, doubleLinkedList.indexOf("999"));

assertEquals(-1, doubleLinkedList.indexOf("99"));

assertEquals(0, doubleLinkedList.lastIndexOf("999"));

assertEquals(4, doubleLinkedList.lastIndexOf(null));

doubleLinkedList.remove(s);

assertEquals(-1, doubleLinkedList.lastIndexOf(null));

 

doubleLinkedList.repOK();

doubleLinkedList.inList(doubleLinkedList.entry(0));

doubleLinkedList.inList(doubleLinkedList.entry

(1));

doubleLinkedList1.inList(doubleLinkedList.entry(0));

DoubleLinkedList doubleLinkedList2 = null;

doubleLinkedList1.repOK();

Object[] objects ={object};

doubleLinkedList.toArray(objects);

DoubleLinkedList doubleLinkedList3 = new DoubleLinkedList();

Object[] objects1 ={object,object,object,object,object,object,object};

doubleLinkedList.toArray(objects1);

collection.clear();

doubleLinkedList3.addAll(0, collection);

doubleLinkedList3.addAll(4, collection);

doubleLinkedList1.addAll(1, collection);

doubleLinkedList1.addAll(55, collection);

// Class

>c=DoubleLinkedList.class;

// Method[]methods=c.getDeclaredMethods();

// for(Methodm:

methods){

// System.out.println(m.getName());

// }

assertEquals(true, doubleLinkedList.entry(3).previous.repOK());

 

}

}

2〕NextDay

3)}Vector

Vector是一个可扩展容器

测试类中创建vector实例

代码:

importstatic org.junit.Assert.*;

import java.util.ArrayList;

import java.util.Collection;

import org.junit.Test;

 

publicclass VectorTest{

Test

publicvoid test(){

Vectorvector = newVector();

Vectorvector4 = newVector(1,2);

try {

Vectorvector2 = newVector(-1,1);

} catch (Exception e){

assertEquals(true, einstanceof IllegalArgumentException);

}

Collection collection = new ArrayList();

Object object1 = new Object();

Object object2 = new Object();

Object object3 = new Object();

collection.add(object1);

collection.add(object2);

Vectorvector3 = new Vector(collection);

vector.ensureCapacity

(2);

vector3.ensureCapacity

(2);

vector3.ensureCapacity(3);

vector4.ensureCapacity(5);

 

assertEquals(2, vector3.size());

assertEquals(true, vector3.contains(object1));

assertEquals(false, vector3.contains(null));

assertEquals(0, vector3.indexOf(object1));

vector3.setElementAt(object2,1);

try {

vector3.setElementAt(object2,2);

} catch (Exception e){

assertEquals(true, einstanceof ArrayIndexOutOfBoundsException);

}

vector3.removeElement(object2);

vector3.removeElement(object3);

vector3.addElement(object2);

vector3.removeElementAt

(1);

 

vector3.get(0);

try {

vector3.get

(2);

} catch (Exception e){

// TODO:

handleexception

}

try {

vector3.removeElementAt(3);

} catch (Exception e){

// TODO:

handleexception

}

try {

vector3.removeElementAt(-1);

} catch (Exception e){

// TODO:

handleexception

}

vector3.addElement(object2);

vector3.addElement(object2);

vector3.addElement(object2);

vector3.removeElementAt

(2);

vector3.addElement(null);

vector3.indexOf(null,1);

}

}

五.总结与分析

1.知识薄弱,测试类容易重复

2.分支覆盖

3.画树状图有利于分析代码
