A million Dollar question!!!
Why does Software have bugs?
There are many reasons for Bug in software, Most are man introduced and some are machine oriented.
Here is the the broad list:
1. Miscommunication or no communication -
As to specifics of what an application should or shouldn’t do (the application’s requirements).
2. Software complexity -
The complexity of current software applications can be difficult to comprehend for anyone without experience in modern-day software development. Windows-type interfaces, client-server and distributed applications, data communications, enormous relational databases, and sheer size of applications have all contributed to the exponential growth in software/system complexity. And the use of object-oriented techniques can complicate instead of simplify a project unless it is well-engineered.
3. Programming errors -
Programmers, like anyone else, can make mistakes.
4. Changing requirements -
The customer may not understand the effects of changes, or may understand and request them anyway - redesign, rescheduling of engineers, effects on other projects, work already completed that may have to be redone or thrown out, hardware requirements that may be affected, etc. If there are many minor changes or any major changes, known and unknown dependencies among parts of the project are likely to interact and cause problems, and the complexity of keeping track of changes may result in errors. Enthusiasm of engineering staff may be affected. In some fast-changing business environments, continuously modified requirements may be a fact of life. In this case, management must understand the resulting risks, and QA and test engineers must adapt and plan for continuous extensive testing to keep the inevitable bugs from running out of control.
5. Time pressures -
Scheduling of software projects is difficult at best, often requiring a lot of guesswork. When deadlines loom and the crunch comes, mistakes will be made.
Egos - people prefer to say things like:
‘no problem’
‘piece of cake’
‘I can whip that out in a few hours’
‘it should be easy to update that old code’
Instead of:
‘that adds a lot of complexity and we could end up
making a lot of mistakes’
‘we have no idea if we can do that; we’ll wing it’
‘I can’t estimate how long it will take, until I
take a close look at it’
‘we can’t figure out what that old spaghetti code
did in the first place’
If there are too many unrealistic ‘no problem’s’, the result is bugs.
1. Poorly documented code -
It’s tough to maintain and modify code that is badly written or poorly documented; the result is bugs. In many organizations management provides no incentive for programmers to document their code or write clear, understandable code. In fact, it’s usually the opposite: they get points mostly for quickly turning out code, and there’s job security if nobody else can understand it (’if it was hard to write, it should be hard to read’).
2 Software development tools -
Visual tools, class libraries, compilers, scripting tools, etc. often introduce their own bugs or are poorly documented, resulting in added bugs.

Prajaktha i sincerely advice one thing as you are from commerce background i recommend you to go to finance side it is very difficult to survive in IT field according to the present situations so if possible learn acountiting packages and go in that direction. I know every one now a days looing farwrd to become a test engineer but it is very difficult. If you think that you that capability to go a head in this competition means i really wish u all the best for your commitement
If you are hyderabad means u can take coaching from

you should learn SQL SEVER also.
any way all the best for your career.
keep in touch and all the best once again.
Hi seema,
you did not mention your qualification. One thing i want to mention you seema that your are free with doing any job all these 4 years.
To start a career as test engineer you have to make that 4 years as you worked some where untill unless you keep experience it is impossible to get a job.If you want to keep experience means u should be technically sound in Manual testing, tools like QTP AND LOAD RUNNER, and more over you should have good command over UNIX, SQL SERVER and ORACLE. I am not frightening you this is the basic fact you should know. To get command over this it takes not less than 1 year so once think upon this if you are really want to get into IT job then reoly me again i will give you the details.
keep in touch

hi
i have a doubt
What is the difference between Bug and Defect
hi
i have a doubt
What is the difference between Bug and Defect
Thanks in advance
Defect: When an error found by the test engineer (testing department) then it is called defect Or Defect is nothing but deviation from the requirement.
Bug: if the defect is agreed by the developer then it converts into bug, which has to fix by the developer or post pond to next version. If am wrong pls let me know…..
Thnx
Thanq very munch Mr.jaykay

Can any help me out , wht is rapid test scrip wizard, why it is used in teting tools
Rapid test script wizard
Hi Devi,
RapidTest Script Wizard, which is used in WinRunner, learns the application graphical user interface (which is abbreviated as GUI). It automatically creates a full suite of basic tests. The requirement of testers to create tests one at a time is reduced considerably. This is because the RapidTest Script Wizard walks through the application itself and reverse-engineers the test scripts directly from the application.
The RapidTest Script Wizard learns all the objects or windows which are present in the application. The RapidTest Script Wizard basically performs two tasks. The first task which the RapidTest Script Wizard performs is it systematically opens the windows in your application and learns the description of every GUI object. The wizard then stores the information in a GUI Map file. The second task which the RapidTest Script Wizard performs is it automatically gene rates tests which are based on the information which it learns as it navigates through the application.
Thanks for help!
