软件质量与测试博客

一、Github地址

https://github.com/kangzhishi/wcTest

 

二、PSP表格

三、解题思路

分函数实现功能,并实现通过正则表达式来判断词,行,特殊行。

由空格或逗号分割开的都视为单词,且不做单词的有效性校验,例如:thi#,that视为用逗号隔开的2个单词。

自制arg解析,方便命令行指令功能需求。

四、程序设计实现过程

  • 解析参数

    设计ArgsParser类

  • 针对错误设计函数

    error

  • 针对文件读写设计函数

    getFileContents,fileToWord,findfiles

  • 针对复杂功能设计函数

    countWord,countLine,sumChar

  • 整合功能以及输出

    countFile

  • 五、代码说明
  • public class WordCount {

    public static void main(String[] args) throws FileNotFoundException{
    String[] args ={"-s","WordCount.java"}
    String[] param=args;
    int length=param.length;
    FileInfo fileInfo=null;
    PrintWriter pw=new PrintWriter(new BufferedOutputStream(new FileOutputStream("result.txt",true)));
    if(length==2){
    Command command=analysisCommand(args[0]);
    fileInfo=new FileInfo(Paths.get(args[1]));
    execute(command, fileInfo, pw);
    pw.flush();
    }
    else if(length>2){
    Command[] commands=new Command[length];
    for(int i=0;i<length;i++)
    commands[i]=analysisCommand(args[i]);
    int index;
    if((index=indexOf(Command.OUTPUT, commands))!=-1){
    pw=new PrintWriter(new BufferedOutputStream(new FileOutputStream(args[index+1],true)));
    commands[index]=null;
    }
    String name=param[selectFirstNull(commands)];
    if((index=indexOf(Command.SALL, commands))==-1){
    fileInfo=new FileInfo(Paths.get(name));
    for(Command command:commands)
    if(command!=null)
    execute(command, fileInfo, pw);
    }else{
    commands[index]=null;
    String[] list=new File("").getAbsoluteFile().list(new DirFilter(name));
    for(String item:list){
    FileInfo fileInfo2=new FileInfo(Paths.get(item));
    for(Command command:commands)
    if(command!=null)
    execute(command, fileInfo2, pw);
    }
    }
    pw.flush();

    }
    pw.close();
    }
    private static int selectFirstNull(Command[] commands){
    for(int i=1;i<commands.length;i++)
    if(commands[i]==null&&commands[i-1]!=null)
    return i;
    return -1;
    }
    private static int indexOf(Command command,Command[] commands){
    for(int i=0;i<commands.length;i++)
    if(command.equals(commands[i]))
    return i;
    return -1;
    }
    private static void execute(Command command,FileInfo fileInfo,PrintWriter pw){
    switch (command) {
    case CHAR:pw.write(fileInfo.path()+", 字符数: "+fileInfo.charNum()+"\r\n");break;
    case WORD:pw.write(fileInfo.path()+", 单词数: "+fileInfo.wordNum()+"\r\n");break;
    case LINE:pw.write(fileInfo.path()+", 行 数: "+fileInfo.lineNum()+"\r\n");break;
    case ALL:fileInfo.toFile(pw);break;
    }
    }

    private static Command analysisCommand(String command){
    String string =command.replaceAll("\\s", "");
    if(command.equals("-c"))
    return Command.CHAR;
    else if(command.equals("-w"))
    return Command.WORD;
    else if(command.equals("-s"))
    return Command.SALL;
    else if(command.equals("-a"))
    return Command.ALL;
    else if(command.equals("-e"))
    return Command.EXCEPT;
    else if(command.equals("-l"))
    return Command.LINE;
    else if(command.equals("-o"))
    return Command.OUTPUT;
    else return null;
    }
    }


    class FileInfo{
    private int charNum;
    private int wordNum;
    private int lineSum;
    private int spaceSum;
    private int codeSum;
    private int noteSum;
    private Path path;
    private boolean isAnalysis=false;
    public FileInfo(Path path){
    this.path=path;
    charNum=0;
    wordNum=0;
    lineSum=0;
    spaceSum=0;
    codeSum=0;
    noteSum=0;
    analysis();
    }

    public String path(){
    return path.toString();
    }

    public int charNum(){
    return charNum;
    }
    public int wordNum(){
    return wordNum;
    }
    public int lineNum(){
    return lineSum;
    }


    private void analysis(){
    if(!isAnalysis){
    isAnalysis=true;
    String s;
    BufferedReader in = null;
    try {
    in =new BufferedReader(new FileReader(path.toString()));
    while((s=in.readLine())!=null){
    switch(analysisLine(s)){
    case SPACE:spaceSum++;break;
    case CODE:codeSum++;break;
    case NOTE:noteSum++;break;
    }
    charNum+=s.replaceAll("\\s", "").length();
    wordNum+=s.split("\\W+").length;
    //sb.append(s);
    lineSum++;
    }

    } catch (IOException e) {
    System.out.println("文件不存在"+path());
    }finally{
    try {
    in.close();
    } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
    }
    }
    }
    }
    public void toFile(PrintWriter pw){
    pw.write(path.toString()+", 字符数: "+charNum+"\r\n"
    +path.toString()+", 单词数: "+wordNum+"\r\n"
    +path.toString()+", 行数: "+lineSum+"\r\n"
    +path.toString()+", 代码行/空行/注释行: "+codeSum+"/"+spaceSum+"/"+noteSum+"\r\n");
    }
    public String toString(){
    return path.toString()+"charNum="+charNum+" wordNum="+wordNum+" lineSum="+lineSum+" codeSum="+codeSum+" noteSum="+noteSum+" spaceSum="+spaceSum;
    }

    private Type analysisLine(String line){
    return (line.equals("")||Pattern.matches("\\s+", line))?Type.SPACE:(Pattern.matches("//.*", line)?Type.NOTE:Type.CODE);
    }
    }

    enum Command{
    CHAR,WORD,LINE,ALL,OUTPUT,SALL,EXCEPT;
    }

    enum Type{
    SPACE,CODE,NOTE
    }

    class DirFilter implements FilenameFilter{
    private Pattern pattern;
    public DirFilter(String regex){
    pattern = Pattern.compile(regex);
    }
    public boolean accept(File dir,String name){
    return pattern.matcher(name).matches();
    }
    }

  • 六、测试设计过程
  • 测试过程对于每一项功能单独测试,再进行组合测试,确保覆盖了所有可执行的代码,对文件名输入文件和文件夹也作出了测试,总共设计13个测试用例:

    wc.exe
    wc.exe -a
    wc.exe -a ../test/test.c
    wc.exe -l ../test/test.c -o out1.txt
    wc.exe -w ../test/test.c -o out2.txt
    wc.exe -a ../test/test.c -o out3.txt
    wc.exe -c ../test/test.c -o out4.txt
    wc.exe -l -w -a -c ../test/test.c -o out5.txt
    wc.exe -a ../test/ -o out6.txt
    wc.exe -a -s ../test/ -o out7.txt
    wc.exe -a ../test/*.c -o out8.txt
    wc.exe -a ../test/*.c -e ../stop.txt -o out9.txt
    wc.exe  -l -w -a -c -s ../test/ -e ../stop.txt -o out10.txt

    测试结果见项目下bin

    out10.txt       out3.txt        out5.txt        out7.txt        out9.txt        
    out1.txt        out2.txt        out4.txt        out6.txt        out8.txt        result.txt

       软件测试工作是一个系统而复杂的工程,软件测试的目的就是确保软件的质量、确认软件以正确的方式做了你所期望的事情,所以工作的主要任务是发现软件的错误、有效定义和实现软件成分由底层到高层的组装过程、验证软件是否满足规格书要求和系统定义文档所规定的技术要求、为软件质量模型的建立提供依据。
        而且软件的测试不仅是要确保软件的质量,还要给开发人员提供信息,以方便其为风险评估做相应的准备,以及为其提供分析依据,重要的是要贯穿在整个软件开发的过程中,保证整个  软件开发的过程是高质量的。
       软件测试对测试工程师来讲,要求具备较强的专业知识,严谨细心耐心的测试态度,良好的反向思维、发散思维能力、沟通能力等等。

    七.借鉴了梁锦霖同学的代码,并做了一些改动。
