学号：201531040455项目代码
单独写了一个md文件，放在git上，快速查阅
修正代码风格（变量定义、注释等）
算法错误并没有找到算误，至于效率，我就不是很在意了
由于我没有找到队友（我已经是一个在准备考研的大四老学长），所以我没抽出时间去做这件事
我在上一个文档中已经完成这个部分，所采用的是写一个shell文件自动测试并对比结果（linux自带一个wc命令），得出程序是否正确。有关其详细论述可以参照我的上一个readme，这里只把shell文件内容放出来
#!/bin/sh #Author: seven #date: 2018/09/27 #aim: an automatic script to test the program #a function to print test result #function will receive 2 parameters, #first is the type of the test, #second is whether the test tested as expected test_result_print(){ if [ $2 -eq 1 ] then echo `date "+%Y-%m-%d %H:%M:%S"` " $1 test succeeded!" | tee -a test_log.txt else echo `date "+%Y-%m-%d %H:%M:%S"` " $1 test met with failure!" | tee -a test_log.txt fi } compare_result_with_standard(){ if [ "$1" = "$2" ] then if_test_success=1 else if_test_success=0 fi } test_file_name="input" #Here is the test for ./wc -h #the ideal result is the usage of the program standard_result="Usage: wc.exe [OPTIONS]... [FILE] --character -c calculate the numbers of characters in the file --word -w calculate the numbers of words in the file --line -l calculate the numbers of lines in the file --outtofile=x -o x transfer the result to the specific file" result=`./wc -h` compare_result_with_standard "$result" "$standard_result" test_result_print "wc -h" $if_test_success #Here is the test for ./wc -h input #the ideal result is to print "-h parameter should work alone!" standard_result="-h parameter should work alone!" result=`./wc -h input` compare_result_with_standard "$result" "$standard_result" test_result_print "wc -h print" $if_test_success #Here is the test for wc -w input standard_result=`wc -w $test_file_name | sed 's/[^0-9]//g'` result=`./wc -w $test_file_name | sed 's/[^0-9]//g'` compare_result_with_standard "$result" "$standard_result" test_result_print "wc -w input" $if_test_success #Here is the test for wc -w nothing standard_result="Fail to Open the File!" result=`./wc -w nothing` compare_result_with_standard "$result" "$standard_result" test_result_print "wc -w nothing" $if_test_success #Here is the test for wc -l nothing standard_result="Fail to Open the File!" result=`./wc -l nothing` compare_result_with_standard "$result" "$standard_result" test_result_print "wc -l nothing" $if_test_success #Here is the test for wc -c input standard_result=`wc -c $test_file_name | sed 's/[^0-9]//g'` result=`./wc -c $test_file_name | sed 's/[^0-9]//g'` compare_result_with_standard "$result" "$standard_result" test_result_print "wc -c input" $if_test_success #Here is the test for wc -c nothing standard_result="Fail to Open the File!" result=`./wc -c nothing` compare_result_with_standard "$result" "$standard_result" test_result_print "wc -c nothing" $if_test_success #Here is the test for wc -w -o result.log input standard_result=`wc -w $test_file_name | sed 's/[^0-9]//g'` result=`./wc -w -o result.log $test_file_name | sed 's/[^0-9]//g'` compare_result_with_standard "$result" "$standard_result" test_result_print "wc -w -o result.log input in std output" $if_test_success result=`cat result.log | sed 's/[^0-9]//g'` compare_result_with_standard "$result" "$standard_result" test_result_print "wc -w -o result.log input in outputfile" $if_test_success先看看扩展功能要求： wc.exe -s //递归处理目录下符合条件的文件 wc.exe -a file.c //返回更复杂的数据（代码行 / 空行 / 注释行） wc.exe -e stopList.txt // 停用词表，统计文件单词总数时，不统计该表中的单词 [file_name]: 文件或目录名，可以处理一般通配符。
由于要求使用TDD，所以先写测试用例：
#Here is the test for ./wc -s -w input* standard_result="input, word number:23\ninput1, word number:4" result=`./wc -s -w input*` compare_result_with_standard "$result" "$standard_result" test_result_print "wc -c input" $if_test_success #Here is the test for ./wc -e stop_list.txt input* standard_result="input, word number:21" result=`./wc -e stop_list.txt input` compare_result_with_standard "$result" "$standard_result" test_result_print "wc -c input" $if_test_success #Here is the test for ./wc -a input standard_result="the lines of input is 12\nthe empty of input is 2\nthe explanatory lines of input is 3" result=`./wc -a input` compare_result_with_standard "$result" "$standard_result" test_result_print "wc -c input" $if_test_success下面是脚 本运行情况
seven@mylab:~/wordcount/bin/linux_amd64$ ./test.sh 2018-10-21 20:06:47 wc -h test succeeded! 2018-10-21 20:06:47 wc -h print test succeeded! 2018-10-21 20:06:47 wc -w input test succeeded! 2018-10-21 20:06:47 wc -w nothing test succeeded! 2018-10-21 20:06:47 wc -l nothing test succeeded! 2018-10-21 20:06:47 wc -c input test succeeded! 2018-10-21 20:06:47 wc -c nothing test succeeded! 2018-10-21 20:06:47 wc -w -o result.log input in std output test succeeded! 2018-10-21 20:06:47 wc -w -o result.log input in outputfile test succeeded! 2018-10-21 20:06:47 wc -s -w input test succeeded! 2018-10-21 20:06:47 wc -e stop_list.txt input test succeeded! 2018-10-21 20:06:47 wc -a input test succeeded!最后三排说明我写的程序已经通过了！
用到了一个c 语言的检验工具splint 其运行结果如下
Running from dir: command: C:\Users\seven\splint.exe -standard -preproc -warnposix -retvalint -compdef -usedef -exportlocal -unrecog -imptype \ -bufferoverflowhigh -predboolothers -varuse -type -mayaliasunique -boolops -branchstate -nullpass -nullderef -retvalother \ -nullret -formattype -onlytrans -mustfreefresh -globs -isoreserved -namechecks -isolib -exportfcn -paramuse -exportheader \ -declundef -temptrans -nullassign -formatconst -readonlytrans -noeffect -globstate -compdestroy \ ============= stdout: ============= ============ end stdout ============= ============= stderr: ============= ================================ Checking finished这个意思好像是我的程序一点错都没报，那就是说我写得很完美~
选用所有单元测试中的等价类和无效等价类进行进行测试，然后将各模块进行联合测试。
系统是否满足预期的性能需求。
判断系统是否满足预期的性能需求；寻找软件系统可能存在的性能问题，定位性能瓶颈并解决问题； 判定软件系统的性能表现，预见系统负载压力承受力，在应用部署之前，评估系统性能。（是否满足上线性能要求？系统极限承载如何？系统稳定性如何？）
减少了库的引用，定位到某个要用的模块，而不是整个引用，优化判断分支，减少了判断次数，提高效率，同时减小重复性。
本次写得比较匆忙，没有上一个文档那么认真，主要原因是因为我在准备考研，时间确实紧张，但是我还是改尽我所能多做一些，因为多做课程设计对自己是有帮助的，我也乐意去做一个老师认真布置的作业。
