Software bug life cycle and defect management.
Every software tester must be trying to prove that after fixing one bug in an application that has X number of bugs, the number of remaining bugs in the same application will be X+1.
Summary:
The purpose of this tutorial is to put together all the information that may be useful for software testers about software bugs, bug life cycle in software testing, bug management during software development life cycle (SDLC), types of bug tracking systems and tools, customization of bug tracking systems and tools, as well as a little bit about communication with the developer, fixing bugs and regression testing.

1. What is a bug in software testing?
Let us begin our tutorial with some popular definitions related to software defects /bugs:
The golden rules of software testing defined by Glenford J. Myers, [The Art of Software Testing, 1979]
Testing: run program with intent to find an error
Synonyms of Bug : glitch, error, goof, slip, fault, blunder, boner, howler, oversight, botch, delusion, elision. [B. Beizer, 1990], defect, issue, problem, variance
Defect. The difference between the functional specification (including user documentation) and actual program text (source code and data). Often reported as problem and stored in defect-tracking and problem-management system
Defect. Also called a fault or a bug, a defect is an incorrect part of code that is caused by an error. An error of commission causes a defect of wrong or extra code. An error of omission results in a defect of missing code. A defect may cause one or more failures.[Robert M. Poston, 1996.]
I think that there is no need to explain the above definitions and so we move on.

2. Bug life cycle in software testing
1. When a tester finds a variance from requirement, he/she needs to report the
problem and try to describe it so, that the defect will be easy to reproduce and
understand.
Open new log in XXX system (Can be Problem Originator like Tester or Technical
Support person)
Try to reproduce the problem. If the problem is not reproducible, specify in the
problem log.
Verify whether any duplicates of the same problem is already in the system
Enter full description of the problem
If necessary print the log & attach any supporting printouts
Assign the Priority an Severity of the Problem
Assign the Owner as a responsible person to look after the problem resolution
(may be Development team lead or product manager/coordinator)
In the case when Sales Person receives the problem description from the client,
he/she supplies the problem description to the Technical Support with the names of the
client and the Sales Person the problem came from. The Technical support will be acting
as Problem Originator.
2. Review the Problem (Owner may be Development Leader)
Review the Problem Priority and Severity. If disagree – change the Priority and Severity
and specify the reason why the severity or/and Priority was changed:
3. If this is a bug, but it will not be corrected at this time due to the low
Priority/Severity rating, time or resources limitation:
Escalate for decision/agreement
Set the problem type as appropriate
Annotate the log with recommended solution
Set status to pending
The Development Leader remains as a problem owner until the problem will be
re-assign for resolution, corrected, send to training or closed by the management
decision with a Pending status assigned
4. If this is an environmental issue, initiate the environment correction
process by assigning to the appropriate person
5. If this is an Originator’s error:
Annotate the problem log with explanation
Change problem type to Non a problem, Duplicate or Change Request
Get a Problem Originator’s agreement
Set status to Void
6. If the problem will not be corrected, but it was reported by the Technical
support or Sales as a client complain:
Change problem type to User Education
Annotate the problem log with explanation on the workaround
Get a Problem Originator’s agreement
Assign the Ownership to Product Manager
Set status to Deferred
Consider the problem correction in the next release
7. Fix and Unit test a corrected problem (Owner Developer)
Update the problem log with resolution information
Set the status to Fixed
Pass back to problem Development Leader for Promotion.
Notify Technical Writer with Problem Resolution.
8. Promote any modified programs to the next release, and update the problem
status to Promoted. (Owner - Development Leader)
9. Retest the fix (Originator)
Update the problem log
Change status to Closed or Re-open
Annotate the test execution history with retest information
10. If the problem is fixed:
Change the problem status to Closed
Originator remains as a problem owner after he/she closes the problem
11. If the problem is not fixed or other problems were created as a result of
the fix:
Change status of the problem to Re-open
Annotate the test execution history with retest information
Redirect the ownership to Development Team Leader
NOTE:
Priority 1 problems will require immediate attention, because they will hold up the
testing. If Priority 1 problems will be discovered, the problem resolution will follow
the process that will be structured as follows:
Problem will be logged into the XXX system
The notification with request for immediate problem resolution will be sent to
Development Team Leader
The problem fix will be done in the Test environment and promoted if necessary
into the development after the fix the retest in test environment is done.

3. Activities for tracking all bugs found through SDLC.
The process must be defined and approved for tracking all bugs in a bug tracking system through SDLC.
Every bug must have a unique name that will help find it in the future. The bug name must describe the main details of the defect as well. By correctly tracking we mean that all necessary fields in the bug tracking system must be used correctly. Correct combination of the fields helps in uniquely identifying the bug reported by the tester and for finding duplication in future.It is important to reopen the old, fixed bug instead creating a new bug with the same description.
[Bug Management Back to Top]
4. Types of bug tracking software systems and tools.
For bug tracking, use Bugzilla open-source free bug tracking software , with a web-based interface. Written in Perl, with MySQL database back-end, you can download Bugzilla from http://www.bugzilla.org/ Bugzilla is the best choice if the number of users is greater than 20. Otherwise look for something simpler.
Remember that the use of expensive QA tools does not inherently lead to the creation of a bug-free environment. The brittle, buggy and costly systems can be built with any methodology, technology and software tools for automation testing. For example, try to compare one of the most expensive defect and change tracking systems ClearQuest, with Bugzilla free open-source bug tracking software, and you will find that there are no big differences.
And remember: As Voltaire once said, “better is the enemy of good.” If you search the web, you will find that current experience shows that open source software like Bugzilla is the greatest insurance policy a QA lab can have.

5. Fields selection and customization for bug tracking tools
.
Recommendation on bug tracking software customization.
A variety of free open source, commercial, problem-tracking and bug management software systems and tools is available. These systems and tools allow tracking of all necessary information during software development and the bug life cycle. A detailed description of a bug in this system will give complete information to all involved personnel. See a list of available tools and their comparison on: http://www.aptest.com/bugtrack.html
In order to select the fields that we will use in our bug tracking system, let us first identify all possible field choices.
Bug Components -Bug tracking criteria:
1) Bug # (primary key)
1) Short Description – (defect name)
2) Author (tester or person found a bug)
2) Date bug discovered
3) Bug Status/state (Open, Pending, Verified, Fixed, in test, Closed,)
4) Product/Project Name and version # (Found in Build Number)
5) Software module / Section (if a project has several different code modules)
6) Operating System— if applicable
7) Web Browser— if applicable
8) Test Case name (test case used when bug was discovered)
9) Priority (1-5, or better using definition High, Medium, Low) Crashes must be P1;
Data loss must be P1
10) Originator or Test Engineer name (tester who discovered the bug or assign to
it)
11) Software Engineer (person assigned to repair bug)
12) Developer Resolution— (general text entry)
13) Fixed in Build Number
14) Keywords 1 & 2 (To describe bugs for future database queries)
15) Summary of bug (general text entry)
16) Steps to reproduce (general text entry)
17) Comments (general text entry)
18) Attachments— screenshots, files,
Additional functionality of any bug tracking system:
Customizable fields
Auto-populate fields
Submit by email (automatic Email notification )
Attachments
Let us drill down and add some description to some of the attributes:
Bug priority (Priority is Business):
Must be fixed as soon as possible. Bug is blocking further testing or progress
in this area.
Should be fixed soon, before product release.
Fix if time allows; somewhat trivial. This defect may be postponed. (better
create special maintenance release where all this types of defects will be fixed)
Bug severity can be categorized as follows (Severity is Technical):
Cosmetic (Bug contains typos, unclear wording or non descriptive error messages,
low visibility fields or difficult not friendly navigation.)
Inconvenience (Bug causes minor functionality problems, may affect "fit and
finish".)
Loss of Function (Bug causes loss of major functionality or other severe
problems in the product.)
System crash or hang (Bug causes system crashes in obscure cases.)
Loss of Data (Bug causes system data loss)
And remember the law:
Any non-trivial program that contains a significant number of low-severity
non-critical bugs has evidence for the existence of a critical number at which
the limit of these bugs makes this application unusable.[ersasoft]
Defect can be found in different functions of the system:
Entry of a data
Front-end
Backend
Database of other types of storage
Output
Process or logic
Resolution field (Possible situations)
Need More Information
Not a Bug
Not Reproducible
No Plan to Fix
User Error
Choose only the necessary fields from the above list!
Remember: Adding additional fields to the bug tracking system increases the amount of
work to create and maintain the bug. The project cost rises as well. Keep in mind that
the same rules apply to the test suite and a test log document.

6. Description of a bug in the software testing.
The following are sample requirements for the description of a bug in software testing.
Let’s switch from theory to real world testing. Read the bug description example.
Note that the main attributes of the defect description in the bug tracking system are:
1. The description allows easy reproduction of the problem.
2. The description narrows down the possibilities of recreating the problem.
3. The description eliminates things that can't be related to the problem.
4. The description must help to easily find root causes of a failure.
5. The description must have all critical input values that cause the defect.
Example:
Following the sequence below has unexpected result.
1. open revise applet
2. enter client number for revise
3. go to debtor screen, add new debtor with name and surname (P)
4. go to defendant screen, add a blank record
5. go to creditor screen, add a blank record
6. go to judgment screen, add a blank record
7. click revise button
8. close error message
9. remove blank record from defendant screen
10. click revise button
11. close error message
12. remove blank record from creditor screen
13. click revise button
Unexpectedly nothing appears to have happened. No pop-up message of any
Sort was displayed. The revise button was simply disabled and the application
remained on creditor screen. When go to judgment screen, one can still see the blank record there.
Revise -difficult navigation from judgment to creditor to defendant and
debtor.
How to reproduce: open revise, go to judgement screen. enter some data, click
revise you will return to basic screen with message enter mandatory fields. However, judgment is still highlighted on the tree panel. After entering client number you cannot return to judgement panel by clicking on judgment on the tree panel. You must click on another panel first and then click on judgment.

7. The probability of locating more errors in a module is directly proportional to the number of errors already found in that module.
At first glance, this may seem surprising. However, it has been shown that if certain modules or sections of code contain a high number of errors, subsequent testing will discover more errors in that particular section than in other sections.
Consider a program that consists of two modules, A and B. If testing reveals five errors in module A and only one error in module B, module A will likely display more errors than module B in any subsequent tests.
Why is this so? There is no definitive explanation, but it is probably due to the fact that the error prone module is inherently complex or was badly programmed. By identifying the most “bug prone” modules, the tester can concentrate efforts there (if this module has high business risk factor) and achieve a higher rate of error detection than if all portions of the system were given equal attention.
[Bug Management Back to Top]
8. Regression testing and reproducible test cases.
Reproducible test cases become important later when a program is revised, due to the discovery of bugs or because the user requests new options. In such cases, the revised program can be put through the same extensive tests that were used for the original version. (Extensive testing of the system after modifications have been made is referred to as regression testing.) Without saved test cases, the temptation is strong to test only the logic handled by the modifications. This is unsatisfactory because changes, which fix one, problem often, create a host of other apparently unrelated problems elsewhere in the system. As considerable time and effort are spent in creating meaningful tests, tests which are not documented or cannot be duplicated should be avoided.
[Bug Management Back to Top]
9. Communication between software testers and developers, as well as developers’ view on bug fixing
There is a different view between developers and testers on bug fixing. (Tips for Beginners)
Sometimes bug fixing really only introduces additional bugs and does not even fix the existing problem. In a complex system, it is sometimes easier to rewrite all modules / classes than it is to fix the existing defect. There are some cases when it is impossible to fix the bug without rewriting the application. However, developers never like bug fixing and almost never confirm that it is their mistake in the code. Some fixes are very simple, like changing one number (e.g., if boundary conditions do not match the requirements.)
Finding a bug is sometimes the same or requires even more of the art of thinking than does fixing that bug.
The main philosophy is that the competence and attitude of individual testers and developers is the single most important component of a successful project.
Sometimes bugs (defect, issue, problem, error) are valid but don’t really hold any importance from the user’s point of view and sometimes only enhance the application’s behaviour in comparison to the requirements. If coding was done by an experienced developer who understands the users’ needs well, he or she can suggest a better, or more user friendly, solution. However, it is still formally known as a bug and in this case the requirement document must be fixed and sometimes approved to match the real behaviour of the system.
Sometimes one bug in a software application may cost millions of dollars for banks or other financial institutions and sometimes it can put human life in danger (e.g. if the software is used in the medical or aircraft industry.) When you define severity and priority to the bug you must take into account the influence of many different factors such as technical risk, business risk, and the frequency of use of the current function.
As an example, for a common financial application, rounding is the main possible source of bugs.
Many bugs can be called problematic, particularly when you are running a usability test.
What is obvious navigation through the application from one person’s point of view may be difficult to understand for another person with a different mentality.
Lets switch from theory to the real world testing and be prepared receive the following replies from developers after they review your bug description.
Top 24 replies by programmers when their programs don't work :
24. "It works fine on MY computer"
23. "Who did you login as ?"
22. "It's a feature"
21. "It's WAD (Working As Designed)"
20. "That's weird..."
19. "It's never done that before."
18. "It worked yesterday."
17. "How is that possible?"
16. "It must be a hardware problem."
15. "What did you type in wrong to get it to crash?"
14. "There is something funky in your data."
13. "I haven't touched that module in weeks!"
12. "You must have the wrong version."
11. "It's just some unlucky coincidence."
10. "I can't test everything!"
9. "THIS can't be the source of THAT."
8. "It works, but it's not been tested."
7. "Somebody must have changed my code."
6. "Did you check for a virus on your system?"
5. "Even though it doesn't work, how does it feel?"
4. "You can't use that version on your system."
3. "Why do you want to do it that way?"
2. "Where were you when the program blew up?"
1. "I thought I fixed that."

10. Murphy's Laws about bugs
**********************
Any non-trivial program contains at least one bug
There's always one more bug.
Every program has at least one bug.
Programmers also know that every program has at least one line of unnecessary source code. By combining these two rules and using logical induction, it's a simple matter to prove that any program could be reduced to a single line of code with a bug.
Undetectable errors are infinite in variety, in contrast to detectable errors, which by definition are limited.
In any program, any error which can creep in will eventually do so.
Not until the program has been in production for at least six months will the most harmful error be discovered.

11. If you decided to design you own bug tracking system you can use the following
document as a draft of Requirements.
Introduction
Bug tracking system.
The purpose of this document is to describe Requirements for the selection/creation of
the Bug Tracking on-line system that will support basic requirements. Bug Tracking
Procedure must support internal as well as possible remote locations.
Bug Tracking System - Project Overview.
Describe specific to your company requirements to bug tacking software..
General Bug Tracking Process for the XXX program.
All problems found during the testing will be logged in the XXX Bug tracking system,
using a single database for all participating systems. Everyone who will be testing,
fixing bugs, communicating with a clients, or managing teams doing either activity, will
be given “write” access to the database.
Several different kinds of reports and graphs can be produced in XXX using its standard
versions, or using the included report writer to create custom reports. Either of these
can be combined with XXX’s filtering capabilities to report on selection of data.
During the testing activities all promotions to the test environment must be associated
with a problem log, and agreed with a Testing Team. To avoid destabilizing the test
environment unnecessarily, promotions may be scheduled to include several changes,
except for problems classed as high priority (urgent), because they will hold up the
testing.
Updating & Routing Bug Logs
When you route or update a bug log, you should always:
Annotate the log with information about what you did, and/or with the reason you are
routing it to someone else
Change the status (substate) to reflect the log’s new status
Change the owner to the person you are routing the log to
Please do not enter any of the statuses which belong to the state “closed”. These will
be entered by the test team or test manager as appropriate. The restricted statuses are:
Void (use “pending” and the problem type “non-problem” if you think a log should
be voided
Deferred (use “pending” and enter the reason you want to defer the problem in
the log)
Closed (entered by the test team when a fixed and promoted problem has been
retested and confirmed to be fixed)
The Project Management will be review “pending” logs periodically, and decide whether
they should be worked on, voided or deferred.

Alternate bug management by Google
BUGS BUGS BUGS BUGS Template for bug tracking tool.
Assigned to (Assignee)
[Optional] LDAP name of one person who should take the next step in handling this issue.
This person is automatically emailed when the issue is created and whenever anyone changes the value of any field in the issue.
Buganizer administrators specify a default assignee for every component.
CC
[Optional] Zero or more LDAP names of people to email when an issue is created or modified.
Names are LDAP or mailing list names only, no @google, so only Google mailing lists or employees are valid entries.
This is a comma-delimited list. Do not include the “Assign to” name when filing an issue,
because this person is emailed by default.
Attachments
[Optional] Zero or more attachments to the bug. Any file type is accepted.
There is no limit to the number of attachments for an issue, but the maximum total size of each attachment is 100MB.
Blocking
[Optional] The IDs of bugs that this bug prevents from being resolved.
This is a comma-delimited list. Updating this list will automatically update the Depends On field in the listed bugs.
Depends On
[Optional] The IDs of bugs that must be fixed before this bug can be fixed.
Updating this list will automatically update the Blocking field of all listed bugs.
This is a comma-delimited list.
Changed
[Read-only] The date and time when any value in the issue was last changed.
Changelists
[Optional] Zero or more change list (CL) numbers for CLs dealing with this issue in some way.
Only specify CLs that have been submitted; do not specify pending CLs.
Component
[Required] The thing that has the bug or feature request if it is known. When filing an issue, this should be a complete path
to the component.
An infinitely long path is now supported. When filing an issue, you do not need to assign the issue
to a leaf component (that is, one without children).
Additional components can be created only by project and engineering managers.
Created
[Read-only] The date when the bug was created.
Found In
[Optional] Use for versioning by entering the number of the software version where you found the issue, such as 1.1.
Last modified
[Read-only] The date that any field in the issue was last modified.
Notes
[Optional] Detailed description of the problem and running comments as the issue is handled over time.
When filing the issue, describe the steps required to reproduce a bug or how to get to a screen involving a feature request.
The more information you put here, the less likely future issue handlers will need to contact you.
You cannot edit previous entries in the Notes field, not even if you added them; you can add only new values to the Notes field.
Priority
[Required] The importance of a bug, where P0 is the highest priority. This indicates how soon it should be fixed
and how many resources should be allocated to fix it. For example, misspelling "Google" in the search page logo would be low severity (the page function would not be affected),
but high priority (it would be a Very Bad Thing). Setting both fields lets the bug fix team
allocate its time more wisely. See also the Severity description.
Reported by (Reporter)
[Read-only] The Google login of the person who originally reported the bug.
The default value is assigned to the person creating the bug, but this can be modified to give credit where credit is due.
Resolution
[Optional, entered by Buganizer] The final action chosen by the verifier. Values include Not feasible, Works as intended,
Not repeatable, Obsolete, Duplicate, and Fixed.
Severity
[Required] How much the bug affects the use of the product, where S0 is the most severe.
Setting both priority and severity can help prioritize the importance of this bug to bug fixers. For example, misspelling "Google" in the search page logo
would be low severity (the page function would not be affected), but high priority (it would be a Very Bad Thing).
Setting both fields lets the bug fix team allocate its time more wisely.
Severity values have the following text equivalents:
- s0 = System unusable
- s1 = High
- s2 = Medium
- s3 = Low
- s4 = No effect on system
Status
[Required] The current state of the bug. See Life of an issue (see Figure 3.24) for details on how these
values are set in the issue. Available statuses include the following:
- New: The issue has just been created and not assigned yet.
- Assigned: An assignee has been specified.
- Accepted: The assignee has accepted the issue.
- Fix later: The assignee has decided that the issue will be fixed in the future.
- Will not fix: The assignee has decided that the issue will not be fixed for some reason.
- Fixed: The issue has been fixed, but the fix has not been verified.
- Verifier assigned: A verifier has been assigned to the issue.
- Verified: The fix has been verified by the verifier.
Summary
[Required] A descriptive summary of this issue. Be sure to make this as descriptive as possible; when scrolling through
a list of issues in a search result, this is what helps the user decide whether or not to examine the issue further.
Targeted To
[Optional] Use for versioning by entering the number of the software version in which the issue should be fixed, such as 1.2.
Type
[Required] What type of issue:
- Bug: Something that causes the program not to work as expected
- Feature request: Something you would like to see added to the program
- Customer issue: A training issue or general discussion
- Internal cleanup: Something requiring maintenance
- Process: Something tracked automatically via the API
Verified In
[Optional] Use for versioning by entering the number of the software version where the issue fix was verified, such as 1.2.
Verifier
[Required before issue can be resolved] Each issue is assigned one person who has the right to mark the issue as resolved.
This person need not be assigned until the issue is ready to be resolved, but the verifier is the only one who can change the
status to “Verified” (the issue is closed).
The verifier can be the same person as the assignee.
