Defect Management Process in Software Testing (Bug Report Template)

A Defect in software testing refers to a deviation or discrepancy in the software application’s behavior from the specified end user’s requirements or the original business requirements. It stems from an error in the coding, causing the software program to produce results that are incorrect or unexpected, thus failing to meet the actual requirements. Testers encounter these defects while executing test cases.

In practice, the terms “defect” and “bug” are often used interchangeably within the industry. Both represent faults that need to be addressed and rectified. When testers run test cases, they may encounter test results that deviate from the anticipated outcome. This discrepancy in test results is what is referred to as a software defect. Different organizations may use various terms like issues, problems, bugs, or incidents to describe these defects or variations.
