Bug Reporting Rules:
Do not assume all the companies have same approach to writing bug reports
Rule of WWW – What happened, Where it happened, under Which circumstances
“Problem” bug report versus “Solution” bug report
Bug report is not about perfect English
Before reporting a bug, make sure that you are using the latest version of the AUT
Report a bug immediately, do not postpone
Make sure the bug is reproducible before reporting
Minimize number of steps-to-reproduce
Write one bug report for each fix to be verified
The difference between actual and expected results should be clear
Do not quote the violated rules or requirements (developers know them) – just talk about the problem itself
Do not assume developer knows less than you do about the application
Bug reports should be as concise as possible
Bug report should be as complete as possible
Attach screen shots, data files, logs to clarify the bug description
Each “problem” has a story (each decision is a compromise) research before reporting
Use technical terms, not “people off the street” language
