Regression bug, also known as a regression, is a type of software bug that occurs when a change, such as a new feature or a bug fix, inadvertently causes existing functionality to break. This can happen in various stages of software development, including coding, testing, and deployment. Regression bugs are particularly problematic because they can disrupt the stability and reliability of a software application, leading to a poor user experience.

The term "regression" comes from the idea that the software is "regressing" to an earlier, less functional state. These bugs can be introduced in several ways, such as when a developer makes a mistake while modifying code, or when a new feature interacts unexpectedly with existing code. Regression bugs can be particularly challenging to identify and fix because they may not be immediately apparent and can be difficult to reproduce.

To mitigate the risk of regression bugs, software development teams often employ several strategies. These include thorough testing, such as regression testing, which involves re-testing existing functionality after changes have been made. Automated testing tools can also help identify potential regressions early in the development process. Additionally, code reviews and continuous integration practices can help catch and address regression bugs before they reach the end user.

In summary, a regression bug is a software defect that causes previously working functionality to fail after changes have been made. These bugs can be introduced at any stage of development and are challenging to identify and fix. Effective strategies for mitigating regression bugs include thorough testing, code reviews, and continuous integration practices.
