Test environment issues should be treated as part of defect logging in the test management tool.

A defect found during testing that leads to a major requirement change indicates poor requirement analysis during the STLC.

Exploratory testing is a structured activity that fits neatly within the traditional STLC phases.

STLC assumes that once a defect is fixed, it will not need further testing unless it was a critical issue.

A traceability matrix can help ensure that every requirement has at least one corresponding test case.

Usability testing is considered part of STLC only if it is explicitly requested by the client.

Test metrics such as defect density, test execution rate, and test effectiveness are collected only during the test planning phase.

Peer review of test artifacts like test cases and test plans is optional and rarely impacts overall test effectiveness.

Test data should be generated only after test cases have been executed to ensure that the data fits real-world scenarios.

A well-prepared test closure report includes test summary, defect density, and lessons learned.
