Difference Between Error and Bug in Testing

Understanding the distinction between errors and bugs is crucial in the realm of software testing. In software development, both terms are frequently used but often confused or used interchangeably. However, they represent different aspects of issues that arise during the development and testing phases. Errors are mistakes made by developers during coding, which can result from misinterpretation of requirements or logical flaws in the code. These are typically discovered during the coding phase and are corrected before the software reaches the testing phase. Bugs, on the other hand, are defects in the software that occur after the code has been written and compiled. They manifest when the software is executed and can lead to incorrect behavior or performance issues. Bugs are identified during the testing phase, and their resolution is essential for ensuring the software functions as intended. This article delves into the specific differences between errors and bugs, providing insight into their impact on the software development lifecycle, and exploring strategies for managing and mitigating both to enhance software quality.
