What are escaped defects?},{

Escaped defects are defects (errors, bugs) that were not detected and fixed in the early stages of development or testing, but 'escaped' into production or to the end user. Such defects are considered critical in terms of quality because they affect the user and require urgent correction.

For example, if a bug is not identified during unit testing or integration testing, but is discovered after release, it is an escaped defect. The escaped defects metric helps evaluate the effectiveness of quality control and testing processes in the project.
