INTRODUCTION
Enterprise QA is about evidence. Leaders need proof of what was tested, what risks remain, and how release decisions were made. Test coverage and traceability provide that proof when used together.
From a Merito perspective, these are core delivery controls. Coverage shows how much of the system was exercised. Traceability proves that testing connects to requirements, execution results, and defects. Together, they support release governance, audit readiness, and risk-based decision making.
TEST COVERAGE AND TRACEABILITY AS COMPLEMENTARY CONTROLS
TEST COVERAGE AS A COMPLETENESS SIGNAL
Test coverage measures how much of the intended scope has been tested.
Key types:
- Functional coverage across features and workflows
- Requirements coverage linking tests to business needs
- Code coverage showing executed paths during automation
Business value:
- Supports release planning and regression sizing
- Identifies gaps in testing scope
- Highlights over testing in low-risk areas
Risk perspective
- High coverage does not guarantee real-world validation
- Teams may miss critical workflows despite strong metrics
TRACEABILITY AS A GOVERNANCE CONTROL
Traceability connects SDLC artifacts end to end.
Key links:
- Requirements to test cases
- Test cases to execution results
- Failures to defects and resolution status
