Defect Tracking SoftwareWhat is a Defect ?September 4, 2009DTS | Final Year Project | Dept. of CT,YCCEA software Defect is the common term used to describe an error, flaw, mistake, failure, or fault in a computer program or system that produces an incorrect or unexpected result, or causes it to behave in unintended ways.Most defects arise from mistakes and errors made by people in either a program's source code or its design, and a few are caused by compilers producing incorrect code.Defects can have a wide variety of effects, with varying levels of inconvenience to the user of the program. Some defects have only a subtle effect on the program's functionality, and may thus lie undetected for a long time. More serious defects may cause the program to crash or freeze leading to a denial of service. Others qualify as security defects and might for example enable a malicious user to bypass access controls in order to obtain unauthorized privileges.
Defect Tracking SoftwareWhat are the Types Of Defects ?September 4, 2009DTS | Final Year Project | Dept. of CT,YCCEConceptual error :Code is syntactically correct, but the programmer or designer intended it to do something else Maths DefectsDivision by zero
Arithmetic overflow or underflow
Loss of arithmetic precision due to rounding or numerically unstable algorithms Logic DefectsInfinite loops and infinite recursion Syntax DefectsUse of the wrong operator, such as performing assignment instead of equality test. In simple cases often warned by the compiler; in many languages, deliberately guarded against by language syntax (continued)Defect Tracking SoftwareWhat are the Types Of Defects ? September 4, 2009DTS | Final Year Project | Dept. of CT,YCCEResource defectsNull pointer dereference
Using an uninitialized variable
Off by one error, counting one too many or too few when looping
Access violations
Resource leaks, where a finite system resource such as memory or file handles are exhausted by repeated allocation without release.
Buffer overflow, in which a program tries to store data past the end of allocated storage. This may or may not lead to an access violation. These defects can form a security vulnerability.
Excessive recursion which though logically valid causes stack overflow (continued)
Defect Tracking SoftwareWhat are the Types Of Defects ?September 4, 2009DTS | Final Year Project | Dept. of CT,YCCECo-programming defectsDeadlock
Race condition
Concurrency errors in Critical sections, Mutual exclusions and other features of concurrent processing. Time-of-check-to-time-of-use (TOCTOU) is a form of unprotected critical section. Team working defectsUnpropagated updates; e.g. programmer changes "myAdd" but forgets to change "mySubtract", which uses the same algorithm. These errors are mitigated by the Don't Repeat Yourself philosophy.
Comments out of date or incorrect: many programmers assume the comments accurately describe the code
Differences between documentation and the actual productDefect Tracking SoftwareSome Unusual DefectsSeptember 4, 2009DTS | Final Year Project | Dept. of CT,YCCEHeisenbugs:Those bugs that manifest only under certain condition . These bugs normally escape the debugger of the developers .Bohrbug:A Bohr bug or bohrbug is a bug that manifests itself consistently under a well-defined (but possibly unknown) set of conditionsMandelbugA mandelbug is a computer bug whose causes are so complex that its behavior appears chaotic.SchroedinbugA schroedinbug is a bug that manifests only after someone reading source code or using the program in an unusual way notices that it never should have worked in the first place, at which point the program promptly stops working for everybody until fixed.Defect Tracking SoftwareWhat is a Defect Tracking System ?September 4, 2009DTS | Final Year Project | Dept. of CT,YCCEDefect tracking is the process of finding defects in a product (by inspection, testing, or recording feedback from customers), and making new versions of the product that fix the defects. Defect tracking is important in software engineering as complex software systems typically have tens or hundreds or thousands of defects: managing, evaluating and prioritizing these defects is a difficult task.Defect tracking systems are computer database systems that store defects and help people to manage them.A Defect tracking system is a software application that is designed to help quality assurance and programmers keep track of reported software defects in their work. It may be regarded as a sort of issue tracking system
Defect Tracking SoftwareWhy is it Necessary ?Software defects are expensive. Moreover, the cost of finding and correcting defects represents one of the most expensive software development activities. For the foreseeable future, it will not be possible to eliminate defects. While defects may be inevitable, we can minimize their number and impact on our projects. To do this development teams need to implement a defect management process that focuses on preventing defects, catching defects as early in the process as possible, and minimizing the impact of defects. A little investment in this process can yield significant returnsSeptember 4, 2009DTS | Final Year Project | Dept. of CT,YCCE
Cost of Defects during the Software LifeCycle
Defect Tracking SoftwareWhat are the Components of a good Defect Tracking System ?A major component of a bug tracking system is a database that records facts about known defects. Facts may include the time a bug was reported, its severity, the erroneous program behavior, and details on how to reproduce the bug; as well as the identity of the person who reported it and any programmers who may be working on fixing it.Typical bug tracking systems support the concept of the life cycle for a bug which is tracked through status assigned to the bug. A bug tracking system should allow administrators to configure permissions based on status, move the bug to another status, or delete the bug. The system should also allow administrators to configure the bug statuses and to what status a bug in a particular status can be moved to.September 4, 2009DTS | Final Year Project | Dept. of CT,YCCE
Defect Tracking SoftwareWhy is it Critical to software development ?defects can have a wide variety of effects, with varying levels of inconvenience to the user of the program. Some defects have only a subtle effect on the program's functionality, and may thus lie undetected for a long time. More serious defects may cause the program to crash or freeze leading to a denial of service. Others qualify as security defects and might for example enable a malicious user to bypass access controls in order to obtain unauthorized privileges.September 4, 2009DTS | Final Year Project | Dept. of CT,YCCE
Defect Tracking SoftwareExamples of Extreme Effects of DefectsDefects in the code controlling the Therac-25 radiation therapy machine were directly responsible for some patient deaths in the 1980s. In 1996, the European Space Agency's US$1 billion prototype Ariane 5 rocket was destroyed less than a minute after launch, due to a bug in the on-board guidance computer program. In June 1994, a Royal Air Force Chinook crashed into the Mull of Kintyre, killing 29. It was caused by a software bug in the aircraft's engine control computer. September 4, 2009DTS | Final Year Project | Dept. of CT,YCCE
Defect Tracking SoftwareFinancial ImplicationsIn 2002, a study commissioned by the US Department of Commerce' National Institute of Standards and Technology concluded that software defects, or errors, are so prevalent and so detrimental that they cost the US economy an estimated $59 billion annually, or about 0.6 percent of the gross domestic product.As per GARTNER estimates the global market for testing will be about $13 bn by 2010 . And Indian IT companies would take over 70 % of testing market. September 4, 2009DTS | Final Year Project | Dept. of CT,YCCE
Defect Tracking SoftwareWhat is the standard methods of Defect Classification?The mainly used defect classification approaches have been proposed by companies: IBM and HP. The IBM approach is called Orthogonal Defect Classification (ODC) . A defect is classified across the dimensions: Defect type
Source
Impact
Trigger
Phase found
Severity (continued)September 4, 2009DTS | Final Year Project | Dept. of CT,YCCE

Defect Tracking SoftwareWhat software does Sun use for Defect Tracking ?September 4, 2009DTS | Final Year Project | Dept. of CT,YCCESun uses a software called BugDB , for managing its hardware and software defects .It has a rich set of user interfaces and reporting tools.It has been recently shifted from the SYBASE database to Oracle Database .
Defect Tracking SoftwareWhat software does Open Source (Firefox, Linux) Use ?September 4, 2009DTS | Final Year Project | Dept. of CT,YCCEBoth Linux and Firefox use BugZilla for the Defect Tracking.BugZilla Supports the following features that make it very attractive for users The ability to run on freely available, open source tools. While Bugzilla development includes work to support commercial databases, tools, and operating systems, this is not intended to come at the expense of open source ones.
The maintenance of speed and efficiency at all costs. One of Bugzilla's major attractions to developers is its lightweight implementation and speed, so calls into the database are minimized whenever possible, data fetching is kept as light as possible, and generation of heavy HTML is avoided.

  • 6. Defect Tracking SoftwareWhat is a Defect ?September 4, 2009DTS | Final Year Project | Dept. of CT,YCCEA software Defect is the common term used to describe an error, flaw, mistake, failure, or fault in a computer program or system that produces an incorrect or unexpected result, or causes it to behave in unintended ways.Most defects arise from mistakes and errors made by people in either a program's source code or its design, and a few are caused by compilers producing incorrect code.Defects can have a wide variety of effects, with varying levels of inconvenience to the user of the program. Some defects have only a subtle effect on the program's functionality, and may thus lie undetected for a long time. More serious defects may cause the program to crash or freeze leading to a denial of service. Others qualify as security defects and might for example enable a malicious user to bypass access controls in order to obtain unauthorized privileges.

  • 11. Off by one error, counting one too many or too few when looping
  • 13. Resource leaks, where a finite system resource such as memory or file handles are exhausted by repeated allocation without release.
  • 14. Buffer overflow, in which a program tries to store data past the end of allocated storage. This may or may not lead to an access violation. These defects can form a security vulnerability.
  • 15. Excessive recursion which though logically valid causes stack overflow (continued)

These errors are mitigated by the Don't Repeat Yourself philosophy.
  • 19. Comments out of date or incorrect: many programmers assume the comments accurately describe the code
  • 20. Differences between documentation and the actual productDefect Tracking SoftwareSome Unusual DefectsSeptember 4, 2009DTS | Final Year Project | Dept. of CT,YCCEHeisenbugs:Those bugs that manifest only under certain condition . These bugs normally escape the debugger of the developers .Bohrbug:A Bohr bug or bohrbug is a bug that manifests itself consistently under a well-defined (but possibly unknown) set of conditionsMandelbugA mandelbug is a computer bug whose causes are so complex that its behavior appears chaotic.SchroedinbugA schroedinbug is a bug that manifests only after someone reading source code or using the program in an unusual way notices that it never should have worked in the first place, at which point the program promptly stops working for everybody until fixed.Defect Tracking SoftwareWhat is a Defect Tracking System ?September 4, 2009DTS | Final Year Project | Dept. of CT,YCCEDefect tracking is the process of finding defects in a product (by inspection, testing, or recording feedback from customers), and making new versions of the product that fix the defects. Defect tracking is important in software engineering as complex software systems typically have tens or hundreds or thousands of defects: managing, evaluating and prioritizing these defects is a difficult task.Defect tracking systems are computer database systems that store defects and help people to manage them.A Defect tracking system is a software application that is designed to help quality assurance and programmers keep track of reported software defects in their work. It may be regarded as a sort of issue tracking system
  • 21. Defect Tracking SoftwareWhy is it Necessary ?Software defects are expensive. Moreover, the cost of finding and correcting defects represents one of the most expensive software development activities. For the foreseeable future, it will not be possible to eliminate defects. While defects may be inevitable, we can minimize their number and impact on our projects. To do this development teams need to implement a defect management process that focuses on preventing defects, catching defects as early in the process as possible, and minimizing the impact of defects. A little investment in this process can yield significant returnsSeptember 4, 2009DTS | Final Year Project | Dept. of CT,YCCE
  • 22. Cost of Defects during the Software LifeCycle
  • 23. Defect Tracking SoftwareWhat are the Components of a good Defect Tracking System ?A major component of a bug tracking system is a database that records facts about known defects. Facts may include the time a bug was reported, its severity, the erroneous program behavior, and details on how to reproduce the bug; as well as the identity of the person who reported it and any programmers who may be working on fixing it.Typical bug tracking systems support the concept of the life cycle for a bug which is tracked through status assigned to the bug. A bug tracking system should allow administrators to configure permissions based on status, move the bug to another status, or delete the bug. The system should also allow administrators to configure the bug statuses and to what status a bug in a particular status can be moved to.September 4, 2009DTS | Final Year Project | Dept. of CT,YCCE
  • 24. Defect Tracking SoftwareWhy is it Critical to software development ?defects can have a wide variety of effects, with varying levels of inconvenience to the user of the program. Some defects have only a subtle effect on the program's functionality, and may thus lie undetected for a long time. More serious defects may cause the program to crash or freeze leading to a denial of service.

  • 25. Defect Tracking SoftwareExamples of Extreme Effects of DefectsDefects in the code controlling the Therac-25 radiation therapy machine were directly responsible for some patient deaths in the 1980s. In 1996, the European Space Agency's US$1 billion prototype Ariane 5 rocket was destroyed less than a minute after launch, due to a bug in the on-board guidance computer program. In June 1994, a Royal Air Force Chinook crashed into the Mull of Kintyre, killing 29. It was caused by a software bug in the aircraft's engine control computer. September 4, 2009DTS | Final Year Project | Dept. of CT,YCCE
  • 26. Defect Tracking SoftwareFinancial ImplicationsIn 2002, a study commissioned by the US Department of Commerce' National Institute of Standards and Technology concluded that software defects, or errors, are so prevalent and so detrimental that they cost the US economy an estimated $59 billion annually, or about 0.6 percent of the gross domestic product.As per GARTNER estimates the global market for testing will be about $13 bn by 2010 . And Indian IT companies would take over 70 % of testing market. September 4, 2009DTS | Final Year Project | Dept. of CT,YCCE

  • 219. Defect Tracking SoftwarePlug-in applicationsPlug-in applications are programs that can easily be installed and used as part of your Web browser. Initially, the Netscape browser allowed you to download, install, and define supplementary programs that played sound or motion video or performed other functions. These were called helper applications. A plug-in application is recognized automatically by the browser and its function is integrated into the main HTML file that is being presented.September 4, 2009DTS | Final Year Project | Dept. of CT,YCCE
