Defect leakage in software testing refers to the situation where defects or bugs in a software system remain undetected during the testing process and are discovered later on by the end-users or customers.
It occurs when the testing team fails to identify all the defects in the software, resulting in issues and errors that can negatively impact the user experience.
Defect leakage can be caused by various factors such as inadequate test coverage, insufficient testing, or a lack of proper communication between the testing and development teams.
