What makes a bug severe?
What makes a bug severe? Difficulty of fixing? But that can seldom be known in advance.Microsoft uses a four-point scale to describe severity of bugs.
Severity 1 is a crash or anything that loses persistent data , i.e., messing up your files on disk.
Sev 2 is a feature that doesn't work.
Sev 3 is an aspect of a feature that doesn't work.
Sev 4 is for purely cosmetic problems, misspellings in dialogs, redraw issues, etc. This system works very well. (Interestingly, sev 4 bugs end up getting set to priority 1 fairly often, because they are frequently VERY annoying to users, and fixing them is generally easy and doesn't destabilize things.) -- MichaelGates
怎样定义Bug的严重性？
怎样定义Bug的严重性？与修复的难度相关？但是很少事先就能知道。微软用4个级别来描述Bug的严重性。
severity 1 就是导致死机，崩溃或数据丢失等，比如，弄乱你硬盘上的文件。
Sev2 就是功能、特性失效。
Sev3 就是特性失效的某个方面，单一方面。
Sev4 Bug通常终止于被设置成优先级1时。因为他们时常是那些使用户感到很不舒服的bug，并且修复它们通常有非常简单，不是那些造成系统不稳定的因素的bug 谢谢了！！！ 我们公司的测试bug分类也是这样的。
