FAQs On Defect, Bug and Failure
1. In which phases of software development defect, bug and failure come?
Phases in which Software Development Defect comes:
- In Testing Phase if Testers find any mismatch they call it as Defect or Bug or Fault.
- In Production Phase if Customers or End Users find any mismatch they call it as Failure.
- In the Development Phase, if developers find any mismatch they call it an Error or mistake.
2. What is the producible defect ?
If in every execution i.e, if every time defect came then it is called producible defect.
3. How failure analysis is done in software engineering?
To analyse failure some techniques are used like Fault Tree Analysis (FTA), Failure Mode and Effects Analysis (FMEA).
Differences between defect, bug and failure – Software Engineering
Generally, when the system/application does not act as per expectation or abnormally, we call it an error or it’s a fault, and so on. Many of the newbies in the Software Testing industry are confused about using this, so let’s know what is the difference between defect, bug, error, and failure. We will see these terms in detail one by one.
