6. Defect Tracking Software What is a Defect ? September 4, 2009 DTS | Final Year Project | Dept. of CT,YCCE A 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.

8. Arithmetic overflow or underflow

10. Using an uninitialized variable

11. Off by one error, counting one too many or too few when looping

12. Access violations

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)

17. Race condition

19. Comments out of date or incorrect: many programmers assume the comments accurately describe the code

21. Defect Tracking Software Why 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 returns September 4, 2009 DTS | Final Year Project | Dept. of CT,YCCE

22. Cost of Defects during the Software LifeCycle

23. Defect Tracking Software What 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.

24. Defect Tracking Software Why 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.

25. Defect Tracking Software Examples of Extreme Effects of Defects Defects 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, 2009 DTS | Final Year Project | Dept. of CT,YCCE

26. Defect Tracking Software Financial Implications In 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.

191. Defect Tracking Software Software Testing Life Cycle- Phases Define testing ? Process of exercising or evaluating a system or system component by manual or automated means to verify that it satisfies specified requirement (IEEE 83a) What is Testing? process used to help identify the correctness, completeness and quality of developed computer software. Find out difference between actual and expected behavior. The process of exercising software to verify that it satisfies specified requirements of end user and to detect errors We Test !! We Test !! Why Detect programming errors - programmers, like anyone else, can make mistakes. To catch bugs/defect/errors. To check program against specifications Cost of debugging is higher after release Client/end user should not find bugs Some bugs are easier to find in testing Challenge to release a bug-free product.

192. Defect Tracking Software Software Testing Life Cycle- Phases Requirement Analysis The objective of Requirement Analysis is to ensure software quality by eradicating errors as earlier as possible in the development process, as the errors noticed at the end of the software life cycle are more costly compared to that of early ones, and there by validating each of the Outputs.

207. Defect Tracking Software SOME IMPORTANT TERMS Versioning Control Systems (VCS) are useful for recording the history of documents edited by several developers. History Touch (HT). We define a history touch to be one of the commit actions where changes made by developers are submitted and include modifying, adding or removing files. History. The history of a file subsumes all HTs that occurred to that file from its birth until present Release is a point in time in the history of a project which denotes that a new or upgraded version is available. Defect count is the number of defects identified in a file. The file a is more fault-prone than the file b if the defect count of the file ais higher than the defect count of the file b.
