what is defect in software testing

In software testing, a defect refers to any error or bug in the system under test that causes it to behave differently than the expected or specified behavior. When the actual result of a test case deviates from the expected result, we consider it a defect. This could be due to issues in the software’s code, design, or logic.

For example, if a calculator app is expected to return the result ‘4’ when ‘2’ and ‘2’ are added together, but it instead returns ‘5’, this would be considered a defect.

The goal of software testing is to find and document these defects so they can be fixed before the software is released. Defects are usually logged into a defect tracking system with details such as:

1. Description of the defect.
2. Steps to reproduce the defect.
3. Expected and actual outcomes.
4. Severity and priority of the defect.
5. Screen shots or other relevant information.

The process of finding, documenting, and tracking these defects is a critical part of ensuring software quality. It helps to prevent defective software from being delivered to end users, and it provides a way to manage the process of fixing issues and verifying that they have been resolved.

It’s worth noting that not all defects are created equal. Some may have a minor impact on the software’s functionality or usability, while others may be critical and prevent the software from functioning at all. The severity of a defect often determines its priority for being fixed.
