上一篇为 bug统计分析初步
本篇重点讨论基于sql的bug统计分析方法。
1、与时间和状态的关系:
1)考察每个时间单位(年、月、日)产生的bug量
2)考察每个时间单位(年、月、日)解决的bug量
3)考察每个时间单位(年、月、日)遗留的bug量
4)考察每个bug遗留的时间单位(年、月、日)
5)考察平均bug遗留的时间单位(年、月、日)
6)通过结合1)、2)、3)考察分析发现、解决bug的时间段(月、日、时)峰值
其中6可以用来指导测试、开发效率
2、与时间、角色的关系:
1)考察每个测试每个月发现的bug量
2)考察每个开发每个月解决的bug量
3)考察每个测试自开发提交版本测试之后,发现每个新bug的时延
4)考察每个开发自测试提交bug之后,解决每个新bug的时延
此1234均可以用来指导绩效考核
3、其他可以考虑与bug发生关系的系数:
1)基于项目划分
2)基于模块(硬件、固件、底层软件、上层应用(前端、后台)等,根据不同项目可以不同的划分情况)
3)基于功能性质划分(非致命、一般、界面、崩溃等)
4)基于重现概率划分
等等
3、高级扩展
1)判断一个bug是否是难bug,并把它找出来:根据解决时延、重复reopen的次数、测试和开发人员的标注
2)定义每个项目子模块解决本项目子模块bug最多的人为项目子模块负责人,查询每个人所负责的项目子模块数等
4、案例:
使用bugfree,会发现一个问题,所有的bug信息都放在一张表bf_buginfo里。ModulePath字段在项目有多个子模块时,是作为整字段中间加‘/‘区分层级的。
下面是我用到的一些SQL统计语句(为其中一个考察点,笔者在下一篇博客里专门抽象出一个SQL面试题):
#--查询bug总体情况 #select ProjectName,ModulePath,BugTitle,BugStatus,OpenedDate from bf_buginfo order by ProjectName,ModulePath,OpenedDate; #--查询每个项目的bug数目(XXXX算一个项目) #select count(*),ProjectName from bf_buginfo group by ProjectName having count(*) >= 1; #--查询XXXX项目每个模块的bug数目 #select count(*),ModulePath from bf_buginfo where ProjectName like 'XXXX' group by ModulePath having count(*) >= 1; #select * from bf_buginfo where ProjectName like 'XXXX' and ModulePath = '/'; #select BugId,ProjectName,ModulePath,BugTitle,BugStatus,OpenedDate from bf_buginfo order by OpenedDate,ResolvedDate,ClosedDate group by DATE_FORMAT(OpenedDate,'%Y%m'); #--查询每个月产生的bug数目 #select count(*),DATE_FORMAT(OpenedDate,'%Y-%m') from bf_buginfo group by DATE_FORMAT(OpenedDate,'%Y%m'); #--查询XXXX每个月产生的bug数目 #select count(*),DATE_FORMAT(OpenedDate,'%Y-%m') from bf_buginfo where ProjectName like 'XXXX' group by DATE_FORMAT(OpenedDate,'%Y%m'); #--查询XXXXbug高峰期的详细内容 #select ModulePath,BugTitle,BugStatus,OpenedDate,DATE_FORMAT(OpenedDate,'%Y-%m') from bf_buginfo where ProjectName like 'XXXX' and ( DATE_FORMAT(OpenedDate,'%Y%m') = '201310' or DATE_FORMAT(OpenedDate,'%Y%m') = '201406' ); #--查询XXXXbug状态情况 #select count(*),BugStatus from bf_buginfo where ProjectName like 'XXXX' group by BugStatus #--查询全项目bug状态情况 #select count(*),BugStatus from bf_buginfo group by BugStatus #--查询重难点bug:初级过滤方法:从已解决的bug中分析:reopen的 : 需要了解如何获取reopen的记录 :bf_testaction和bf_buginfo #select count(distinct(bugId)) from Bf_testaction as taction , bf_buginfo as buginfo where ActionType = 'Activated' and taction.idvalue = buginfo.bugid #select count(distinct(bugId)) from bf_testaction as taction , bf_buginfo as buginfo where ActionType = 'Activated' and taction.idvalue = buginfo.bugid and ProjectName like 'XXXX' #activated 226 #activated 138 #--查询重难点bug:初级过滤方法:从已解决的bug中分析:长时间未解决 #690/1695/2715 datediff>=2-fixed/closed/all #select count(*),BugID,ResolvedDate,ProjectName,ModulePath,BugTitle,datediff(ResolvedDate,OpenedDate) from bf_buginfo where bugstatus = 'closed' and datediff(ResolvedDate,OpenedDate) >= 2 and Resolution = 'Fixed' order by ModulePath DESC,BugID DESC #378/927/1248 datediff>=2-fixed/closed/all #ResolvedDate用于对比svn记录,方便查看 #select BugID,ResolvedDate,ProjectName,ModulePath,BugTitle,datediff(ResolvedDate,OpenedDate) from bf_buginfo where ProjectName like 'XXXX' and bugstatus = 'closed' and datediff(ResolvedDate,OpenedDate) >= 2 and Resolution = 'Fixed' order by ModulePath DESC,BugID DESC #--根据解决人查询bug #select count(*),ResolvedBy from bf_buginfo where Resolution = 'fixed' and BugStatus = 'closed' group by ResolvedBy order by count(*) #--定义每个项目子模块解决本项目子模块bug最多的人为项目子模块负责人,查询每个人所负责的项目子模块数 select count(*),ResolvedBy from ( select B.* from (select ModulePath, ResolvedBy, count(*) as num from bf_buginfo where Resolution = 'fixed' and BugStatus = 'closed' group by ModulePath, ResolvedBy) B , (select A.ModulePath, MAX(A.num) as num from ( select ModulePath,ResolvedBy,count(*) as num from bf_buginfo where Resolution = 'fixed' and BugStatus = 'closed' group by ModulePath, ResolvedBy ) A group by A.ModulePath ) C where B.ModulePath = C.ModulePath and B.num = C.num order by B.ResolvedBy ) D group by ResolvedBy
