what is defect

A defect can refer to different things depending on the context. In general, it means an imperfection or abnormality that impairs quality, function, or utility. For example, a heart defect is an abnormality in the heart that impairs its function. In software engineering, a defect is a bug or an error that causes the software to behave in an unwanted or unexpected way. Defects can occur when a developer makes a mistake while building the software. When testing a software application or product, if the actual result deviates from the expected result, it results in a defect. Defects are reported to the development team via a detailed document called a bug report. The bug report contains information such as the defect ID, defect description, steps to reproduce the defect, and severity of the defect.
