Why good Bug report?
If your bug report is effective, chances are higher that it will get fixed. So fixing a bug depends on how effectively you report it. Reporting a bug is nothing but a skill and I will tell you how to achieve this skill.
“The point of writing problem report(bug report) is to get bugs fixed” - By Cem Kaner. If tester is not reporting bug correctly, programmer will most likely reject this bug stating as irreproducible. This can hurt testers moral and some time ego also. (I suggest do not keep any type of ego. Ego’s like “I have reported bug correctly”, “I can reproduce it”, “Why he/she has rejected the bug?”, “It’s not my fault” etc etc..)
What are the qualities of a good software bug report?
Anyone can write a bug report. But not everyone can write a effective bug report. You should be able to distinguish between average bug report and a good bug report. How to distinguish a good or bad bug report? It’s simple, apply following characteristics and techniques to report a bug.
1) Having clearly specified bug number:
Always assign a unique number to each bug report. This will help to identify the bug record. If you are using any automated bug-reporting tool then this unique number will be generated automatically each time you report the bug. Note the number and brief description of each bug you reported.
2) Reproducible:
If your bug is not reproducible it will never get fixed. You should clearly mention the steps to reproduce the bug. Do not assume or skip any reproducing step. Step by step described bug problem is easy to reproduce and fix.
3) Be Specific:
Do not write a essay about the problem. Be Specific and to the point. Try to summarize the problem in minimum words yet in effective way. Do not combine multiple problems even they seem to be similar. Write different reports for each problem.
How to Report a Bug?
Use following simple Bug report template:
This is a simple bug report format. It may vary on the bug report tool you are using. If you are writing bug report manually then some fields need to specifically mention like Bug number which should be assigned manually.
Reporter: Your name and email address.
Product: In which product you found this bug.
Version: The product version if any.
Component: These are the major sub modules of the product.
Platform: Mention the hardware platform where you found this bug. The various platforms like ‘PC’, ‘MAC’, ‘HP’, ‘Sun’ etc.
Operating system: Mention all operating systems where you found the bug. Operating systems like Windows, Linux, Unix, SunOS, Mac OS. Mention the different OS versions also if applicable like Windows NT, Windows 2000, Windows XP etc.
Priority:
When bug should be fixed? Priority is generally set from P1 to P5. P1 as “fix the bug with highest priority” and P5 as ” Fix when time permits”.
Severity:
This describes the impact of the bug.
Types of Severity:
- Blocker: No further testing work can be done.
- Critical: Application crash, Loss of data.
- Major: Major loss of function.
- Minor: minor loss of function.
- Trivial: Some UI enhancements.
- Enhancement: Request for new feature or some enhancement in existing one.
Status:
When you are logging the bug in any bug tracking system then by default the bug status is ‘New’.
Later on bug goes through various stages like Fixed, Verified, Reopen, Won’t Fix etc.
Click here to read more about detail bug life cycle.
Assign To:
If you know which developer is responsible for that particular module in which bug occurred, then you can specify email address of that developer. Else keep it blank this will assign bug to module owner or Manger will assign bug to developer. Possibly add the manager email address in CC list.
URL:
The page url on which bug occurred.
Summary:
A brief summary of the bug mostly in 60 or below words. Make sure your summary is reflecting what the problem is and where it is.
Description:
A detailed description of bug. Use following fields for description field:
- Reproduce steps: Clearly mention the steps to reproduce the bug.
- Expected result: How application should behave on above mentioned steps.
- Actual result: What is the actual result on running above steps i.e. the bug behavior.
These are the important steps in bug report. You can also add the “Report type” as one more field which will describe the bug type.
The report types are typically:
1) Coding error
2) Design error
3) New suggestion
4) Documentation issue
5) Hardware problem
Some Bonus tips to write a good bug report:
1) Report the problem immediately:If you found any bug while testing, do not wait to write detail bug report later. Instead write the bug report immediately. This will ensure a good and reproducible bug report. If you decide to write the bug report later on then chances are high to miss the important steps in your report.
2) Reproduce the bug three times before writing bug report:Your bug should be reproducible. Make sure your steps are robust enough to reproduce the bug without any ambiguity. If your bug is not reproducible every time you can still file a bug mentioning the periodic nature of the bug.
3) Test the same bug occurrence on other similar module:
Sometimes developer use same code for different similar modules. So chances are high that bug in one module can occur in other similar modules as well. Even you can try to find more severe version of the bug you found.
4) Write a good bug summary:
Bug summary will help developers to quickly analyze the bug nature. Poor quality report will unnecessarily increase the development and testing time. Communicate well through your bug report summary. Keep in mind bug summary is used as a reference to search the bug in bug inventory.
5) Read bug report before hitting Submit button:
Read all sentences, wording, steps used in bug report. See if any sentence is creating ambiguity that can lead to misinterpretation. Misleading words or sentences should be avoided in order to have a clear bug report.
6) Do not use Abusive language:
It’s nice that you did a good work and found a bug but do not use this credit for criticizing developer or to attack any individual.
Conclusion:
No doubt that your bug report should be a high quality document. Focus on writing good bug reports, spend some time on this task because this is main communication point between tester, developer and manager. Mangers should make aware to their team that writing a good bug report is primary responsibility of any tester. Your efforts towards writing good bug report will not only save company resources but also create a good relationship between you and developers.
For better productivity write a better bug report.

Hi
Really nice to read this article. I personally feel if you could interrelate this with testcase and execution report that it would give more info. Ie.

If you are working in client place then as per the latest trend all follows V-model where developers, business users and Testers will work together. Which will lead to be productive with best results with time saving and better sharring of thoughts and knowledge with all. There will be very less of misscommunication. Other then that you sprial model is the best one, If you are not working in client side.

Principles of Test Automation
In considering how to approach a systematic and productive test automation effort, it may help to keep the following principles in mind. They are culled from the experience of many test automation engineers and managers, over the last 15 years. Some of them I have explained in detail in my article Test Automation Snake Oil, and in my book Lessons Learned in Software Testing.
Transitioning to Agile Test Automation
1) Establish and announce the role of the test automation team to developers and testers.
2) Establish a reporting system and a dispatching system for the automation team.
3) Make an inventory of known testware within the company.
4) Make a quick survey of testware available outside the company.
5) Have toolsmiths sit with testers, understand how they test, and identify test automation opportunities
6) Create the experience for the testers of making a request and seeing it rapidly granted.
7) Review the progress of the automation effort no less frequently than every two weeks.
8 ) Continue to improve the training of the testers, so that they are better able to conceive of sophisticated test strategies.

Hi All,
On seeing many requests, I feel that the below one would be helpful to you all.
Lets assume in your application you want to create a new user with his/her information, for that you need to logon into the applicataion and navigate to USERS menu > New User, then enter all the details in the User form like, First Name, Last Name, Age, Address, Phone etc. Once you enter all these need to click on SAVE button in order to save the user and you can see a success message saying “New User has been created successfully”.
Now you entered into your application by logging in and navigete to USERS menu > New user, entered all the information and clicked on SAVE button and now the application creashed and you can see one error page
on the screen, now you would like to report this BUG.
BUG REPORT:
Bug Name: Application crash on clicking the SAVE button while creating a new user.
Bug ID : It will be automatically created by the BUG Tracking tool once you save this.
Area Path: USERS menu > New Users
Build Number:/Version Number 5.0.1
Severity: HIGH (High/Medium/Low)
Priority: HIGH (High/Medium/Low)
Assigned to: Developer-X
Created By: Your Name
Cerated On: Date
Reason: Defect
status: New/Open/Active - Depends on the Tool you are using
Environment: Windows 2003/SQL Server 2005
Description:
Application crash on clicking the SAVE button while creating a new
user, hence unable to create a new user in the application.
Steps To Reproduce:
1) Logon into the application
2) Navigate to the USers Menu > New User
3) Filled all the fields
4) Clicked on Save button
5) Seen an error page “ORA1090 Exception: Insert values Error…”
6) See the attached logs for more information
7) And also see the attached screenshot of the error page.
Expected: On clicking SAVE button should be prompted to a success message “New User has been created successfully”.
Save the defect/bug in the BUG TRACKING TOOL.

VijayD

hiiiiiiiiiiiiiiiiiiiii
its very nice article and very usefullllllll.
thank u very much.
Hello……..
i read all the bonus points to write the effective bug report and i totally agreed with u except one……….
here u say before writing the bug report we reproduce it three time but in some case we found the error in single time and in future it will not generate…….then what we will do with these type of bugs……….
e.g. in some case while testing we found the scripting error but if we try to reproduce it then we may or may not get it again.
then I want to know in this case what we will do.
Thanks

In a day how many test cases you write in your company.
or
In a day how many test cases you have to write.
In a day how many test cases you can write in your company
or
In a day how many test cases you have to write.
writing of test cases depends upon the type of task if the task is typical then u have too think too much about the various conditions.
remember one thing better the test cases and the planning best is ur testing and for both of it u have too think deeply.
how do we deal with the bugs which are reproducible but end user has no control on reproducing them, for example there is some test requested and a test number is generated ….. 1 request opens one test # and is shown to end user …. but actually some times 2 test numbers are generated and the other one is hidden.
Thanks ashwani
