Can there be bug-free software application on the planet? Unquestionably. When you are bug-free isn’t the factor that lasts. To become as free from bugs as you possibly can, software needs to be correctly maintained. To become totally free of bugs, software needs to be not used at all. Or it has to come with an army of QA engineers behind it, which will not be cost-effective for that software owner. You have less bugs in software (and that is the direct objective of quality assurance and developers), but it is extremely difficult to become totally free of bugs, except for the easiest products.
If there’s no bug-free software application, then what’s QA for? Is this just any excuses for low quality?
No. Definitely not. Regular tests are vital, it enables to locate and take care of certain classes of bugs which make the majority of greatest problems. Each one of these words concerning the impracticality of getting no bugs don’t imply that developers wish to omit the responsibility of responsibility for the caliber of the program they’ve created. On the other hand, bugs are unacceptable and should be fought against. The factor is they are fought against throughout the whole duration of the program.
What prevents software from being bug-free?
1) Evolution of technology
Consider your just-cooked favourite meal before you. It appears perfect, and tastes perfect. What happens with time? Your food will get cold and fewer tasty. Time does not spare software either – it will not be fresh forever. You need to ensure that it stays warm – relevant, smooth and fast. Let us take advantage apparent example – the forthcoming iOS 7. It introduces radical alterations in the interface of iOS, and software proprietors will need to adjust their goods to iOS 7 to ensure that bugs wouldn’t haunt them and wouldn’t make users abandon the apps. Or there might be updates in APIs that the software is likely to, for example social networking discussing. These updates could potentially cause bugs that must be removed. Never change anything inside your software and bugs can have up themselves.
2) Complexity of the software
There might be an internet site, for example ”Is It Christmas?”, which is completely bug-free. But can you (or anybody) need this type of website for business purposes? Certainly not. What both you and your users require is valuable software that solves some problems. Such software programs are usually sophisticated – and also the more it’s, the greater bugs can be displayed during its lifetime. The correct answer is possible that you’d like to obtain capabilities, and that’s also an origin of new bugs, which must be eliminated.
Keep the software fresh and attractive.
Bug-free software application is really a myth that needs to be treated properly. The very best factor would be to rapidly respond to appearing bugs. After QA calculates all failure scenarios they are able to, there’ll always be something to look more than a certain time. Check out the apps you’ve in your mobile phone – you will find frequent updates, and possibly one half of these concerns bugfixing, that is mentioned in ‘What’s new’. The longest-living and many popular applications (say, Twitter, Dropbox, Gmail etc.) – these undergo updates to keep going longer and turn into fresh, polished and relevant for brand new waves of users.
