A software bug is an error or fault in a computer program making it behave in unexpected ways. Bugs can be present at any stage during SDLC (software development lifecycle), or at the design, development, or user-acceptance testing phase. Whether you are testing a web portal for general bugs or for browser-compatibility issues, proper understanding and elimination are necessary.
Bugs can never be eliminated completely. No software can turn out to be 100 percent bug-free. But the testing team can adopt certain practices so that the elimination of bugs from software becomes easy. A good management system ensures that most bugs are found and fixed well before it enters production. If the testers and developers work efficiently, the time period from a bug’s discovery to its abolition can be minimized.
