This tutorial explains the Sample Bug Report Template field with examples and explanations to give you an exact idea of how to report a Bug:
If all building/development practices result in perfect systems and solutions, there is nothing left to question and validate. However, that is rarely true. Many things go wrong to various degrees and that warrants thorough verification and validation testing to ensure things are in order.
Enter systematic software testing and bug/defect reporting. Bug or Defect reports are part and parcel of a tester’s day-to-day life. We create defects, assign defects, retest fixed defects, find defect root causes, categorize defects per functionality, reference defects in our conversations, etc.
So, it is understandably a very important part of a tester’s job profile.
