Software Testing Tutorial #42 - Defect Bug Error Failure in Testing

In this Software Testing Tutorial, we will learn about difference between defect bug error failure in software testing. There is very minor difference between defects and bug but in the actual scenario we will use bug and defects interchangeably.

A deviation is categorized as bug only if the failure is because of the coding error but if it is related to requirements like missing requirements or misunderstood requirement and the actual outcome is not as per expectation because of the requirement issues then that is known as defect.

**Notes: Defect, Bug, Error, and Failure in Testing - Software Testing Tutorial #42**

**Defect vs. Bug:**
- **Defect**: A broad term encompassing any deviation from the expected result.
- **Bug**: Specifically related to coding errors; deviations from expected results caused by coding mistakes.

- In practice, defects and bugs are often used interchangeably in most scenarios.
- Tools like Jira track both as one category and distinguish them using the "resolution" field.

**Error vs. Failure:**
- **Error**: Mistakes occurring at various stages, including requirements, coding, and testing.
- **Failure**: Occurs when software doesn't perform as expected due to defects or bugs.

**Relationship Between These Terms:**
- Errors can lead to defects or bugs.
- Defects or bugs can result in failures when software is used or tested.
- Not all code errors lead to immediate failures; some remain dormant until specific conditions trigger them.

Defect means.. - any deviation found by the developer is called defects.

Bug- bug is something which is due to of testing team.

Error - it is something which is found by any of thm which could be by the requirements or coding..

Failure- it is something we found when the customer gets any deviation from the expected results..

This is what i understand about these four terms.
