Difference Between Bug And Defect: This is mostly asked question in interviews for all experienced level of testers. bug and defect is a pretty similar term but it has itsw own differences which we are going to see in this post.
The main difference between a bug and a defect is how they are used. “Bug” is a more informal term that developers and users often use to refer to any software problem, while “defect” is a term that is only used in testing and quality assurance to describe problems that don’t work the way they were supposed to.
When referring to issues or problems in a software programme, the terms “bug” and “defect” are frequently used interchangeably. However, there are a few key distinctions between the two:
Difference Between Bug And Defect
Table of Contents
| Aspect | Bug | Defect |
|---|---|---|
| Terminology | Informal term | Formal term |
| Usage | Widely used by developers and users to refer to software issues | Primarily used in the context of software testing and quality assurance |
| Origin | Arises from various sources, such as coding errors, design flaws, or external factors | Arises due to discrepancies between the actual behavior and specified requirements or design |
| Context | Used in general discussions and conversations about software problems | Used specifically during the testing phase to identify deviations from expected behavior |
| Severity | Can range from minor glitches to critical errors affecting functionality | Usually associated with the failure to meet specified requirements and considered as deviations from expected behavior |
| Importance | Addressed during development and maintenance phases | Identified and documented during testing and resolved before release |
| Resolution | Can be fixed without being documented as a formal issue | Typically documented in a defect tracking system and must be resolved and validated |
| Formality | Often resolved informally or through informal communication | Requires a formal process to track, manage, and resolve defects |
Even though these are two different things, the terms are often used interchangeably, and they both mean the same thing: problems or flaws in the software that need to be fixed.
