Traceability

Traceability is the ability to link and track relationships between different artifacts in a software development project. This ensures that every requirement is covered by a test case, and every test case can be traced back to a specific requirement.

Example: A requirement for a login page states, "Users must be able to log in with a valid email and password." Traceability links this requirement to a specific test case that verifies this functionality, and any defects found during testing are also linked to both the test case and the original requirement.
