<p><b>Summary:</b> <b>How would you describe the bug, in

approximately 60 or fewer characters?</b><br>
|
||||
A good summary should <b>quickly and uniquely identify a bug
|

report</b>. Otherwise, an engineer cannot meaningfully identify
|
||||
your bug by its summary, and will often fail to pay attention to
|
||||
your bug report when skimming through a 10 page bug list.<br>
|
||||
<br>
|
||||
A useful summary might be
|
||||
"<tt>PCMCIA install fails on Tosh Tecra 780DVD w/ 3c589C</tt>".
|
||||
"<tt>Software fails</tt>" or "<tt>install problem</tt>" would be

browser's content region.)

<p><b><a name="tips"></a> 1. General Tips for a Useful Bug
|
||||
Report</b>
|
||||
</p>
|
||||
|
||||
<blockquote>
|
||||
<p>
|
||||
<b>Use an explicit structure, so your bug reports are easy to
|
||||
skim.</b> Bug report users often need immediate access to specific
|
||||
sections of your bug. If your Bugzilla installation supports the
|
||||
Bugzilla Helper, use it.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
<b>Avoid cuteness if it costs clarity.</b> Nobody will be laughing
|
||||
at your funny bug title at 3:00 AM when they can't remember how to
|
||||
find your bug.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
<b>One bug per report.</b> Completely different people typically
|
||||
fix, verify, and prioritize different bugs. If you mix a handful of
|
||||
bugs into a single report, the right people probably won't discover
|
||||
your bugs in a timely fashion, or at all. Certain bugs are also
|
||||
more important than others. It's impossible to prioritize a bug
|
||||
report when it contains four different issues, all of differing
|
||||
importance.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
<b>No bug is too trivial to report.</b> Unless you're reading the
|
||||
source code, you can't see actual software bugs, like a dangling
|
||||
pointer -- you'll see their visible manifestations, such as the
|
||||
segfault when the application finally crashes. Severe software
|
||||
problems can manifest themselves in superficially trivial ways.
|
||||
File them anyway.<br>

<p><b><a name="summary"></a>2. How and Why to Write Good Bug Summaries</b>
|
||||
</p>
|
||||
|
||||
<blockquote>
|
||||
<p><b>You want to make a good first impression on the bug
|
||||
recipient.</b> Just like a New York Times headline guides readers
|
||||
towards a relevant article from dozens of choices, will your bug summary
|
||||
suggest that your bug report is worth reading from dozens or hundreds of
|
||||
choices?
|
||||
</p>
|
||||
|
||||
<p>
|
||||
Conversely, a vague bug summary like <tt>install problem</tt> forces anyone
|
||||
reviewing installation bugs to waste time opening up your bug to
|
||||
determine whether it matters.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
<b>Your bug will often be searched by its summary.</b> Just as
|
||||
you'd find web pages with Google by searching by keywords through
|
||||
intuition, so will other people locate your bugs. Descriptive bug
|
||||
summaries are naturally keyword-rich, and easier to find.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
For example, you'll find a bug titled "<tt>Dragging icons from List View to
|
||||
gnome-terminal doesn't paste path</tt>" if you search on "List",
|
||||
"terminal", or "path". Those search keywords wouldn't have found a
|
||||
bug titled "<tt>Dragging icons
|
||||
doesn't paste</tt>".
|
||||
</p>
|
||||
|
||||
<p>
|
||||
Ask yourself, "Would someone understand my bug from just this
|
||||
summary?" If so, you've written a fine summary.
|
||||
</p>
|
||||
|
||||
<p><b>Don't write titles like these:</b></p>

A good summary should <U>quickly and uniquely identify a bug report</U>. Otherwise,

A summary of "PCMCIA install fails on Tosh Tecra 780DVD w/ 3c589C" is a

examples of a bad title.</P>
