软件测试第二次作业

第一题：

package songjiaming;

import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;

public class shushu {

public void countWord(String str) {
String[] wordsArray = str.split(" ");
Map<String, Integer> wordsMap = new HashMap<String, Integer>();
for (String word : wordsArray) {

if (wordsMap.containsKey(word)) {
wordsMap.put(word, wordsMap.get(word) + 1);
} else {
wordsMap.put(word, 1);
}
}

Set<String> setKey = wordsMap.keySet();
Iterator<String> itKey = setKey.iterator();
while (itKey.hasNext()) {
String word = itKey.next().toString();
int count = wordsMap.get(word);

System.out.println("单词 " + word + " 出现" + count + "次");

}
}

}

JUnit测试

package songjiaming;

import static org.junit.Assert.*;

import org.junit.Test;

public class shushuTest {
@Test
public void testCountWord() {
shushu s1= new shushu();
s1.countWord("Hello World My First Unit Test Test");
}

}

第二题：

package com.song.work2;

import java.util.Scanner;

public class diandao {

public static void reverse(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print("请输入相应的英文：");

String str = input.nextLine();

String[] strArr = str.split("\s+|[,]");

StringBuffer result = new StringBuffer();

for (int i = strArr.length - 1; i >= 0; i--) {

result.append(strArr[i] + " ");

}

result.setCharAt(str.length() - 0, ' ');

System.out.println("颠倒顺序后的结果为：" + result.toString());

}
}

Junit测试代码如下：

package com.song.work2;

import static org.junit.Assert.*;

import org.junit.Test;

public class Question2Test {

@Test
public void test() {
Question2 q2 = new Question2();
q2.reverse(null);;
}

}
