Overview
Measure, Don't Obsess
Code coverage is a useful diagnostic tool but a dangerous primary goal for a QA team.
High coverage can hide poor test quality. Focus on path coverage and meaningful assertions rather than just hitting lines of code.

Best Practices
Dos and Don'ts
Avoid common mistakes that can lead to flaky tests and maintenance nightmares.
What to do
- •Use coverage to find 'dark' areas of the code that aren't tested at all.
- •Set a baseline and prevent coverage from dropping in new PRs.
Common Pitfalls
- •Don't mandate 100% coverage; it leads to 'junk' tests that pass but check nothing.
- •Don't confuse code coverage with functional requirement coverage.
