一、题目简介
写一个程序,计算出一组文本文档的英文单词的频率。
二、源码的github链接

三、所设计的模块测试用例、测试结果截图
本实现有三个方法,分别对三个方法做了测试:
对获取文件中的字符串方法做的三项测试:
1 @Test
2 public void tsetNullFile() throws IOException{
3 File file =null;
4 Deal dos = new Deal();
5 String result = dos.getString(file);
6 assertNull(result);
7 }
8
9 @Test
10 public void testNoContentFile() throws IOException {
11 File file =new File("D:/Empty.txt");
12 Deal dos = new Deal();
13 String result = dos.getString(file);
14 assertEquals("",result);
15 }
16
17 @Test
18 public void testNormalFile() throws IOException {
19 File file =new File("D:/Normal.txt");
20 Deal dos = new Deal();
21 String result = dos.getString(file);
22 assertEquals("hello,my name is Matin,I am thirty-three years old.",result);
23 }
对提取单词的方法做了如下测试:
1 @Test
2 public void testTakeWord() throws IOException {
3 File file =new File("D:/Normal.txt");
4 Deal dos = new Deal();
5 String str = dos.getString(file);
6 List<String> result = dos.takeWord(str);
7 for(String show:result){
8 System.out.print(show);
9 }
10 }
该测试打印结果为:hello my name is Matin I am thirty three years old
对计算单词频率做了如下测试:
1 @Test
2 public void testFrequency() {
3 List<String> list = new ArrayList<String>();
4 list.add("three");
5 list.add("three");
6 list.add("two");
7 list.add("two");
8 list.add("three");
9 list.add("one");
10 list.add("one");
11
12 Deal dos = new Deal();
13 HashMap map = dos.getFrequency(list);
14
15 Iterator iter = map.entrySet().iterator();
16 while (iter.hasNext()) {
17 Map.Entry entry = (Map.Entry) iter.next();
18 String key = (String) entry.getKey();
19 int val = (Integer) entry.getValue();
20 System.out.println(key+":"+val);
21 }
22 }
该测试打印结果:
three:3
two:2
one:2

四、问题及解决方案、心得体会.
这次作业我学会了软件测试的一些操作,对软件测试有了初步的了解 激发了强烈的学习兴趣 以后会好好学习这么课程
