Your tests passed. Your users didn’t.
Code coverage counts the lines your tests ran. TestMap shows the buttons, forms and links they never touched — ranked by how many real users hit them.
Code coverage tells you about your code. Test coverage tells you about your product
94.2% coverage. 847 green tests. And the checkout button 89% of users hit had zero tests. The badge counted lines. Nobody counted the product. Three questions every team should be able to answer:

See what your tests actually protect.
Every page. Every element. Painted from the tests you already run.
Open any page and see which DOM elements your Playwright or Selenium suite touches — and which it skips. Click a red element to read its selector: the test that needs to exist.
Catch the test that quietly stopped clicking.
A refactor renames a selector. A .only slips in. An AI-written test asserts on the wrong element. Line coverage barely moves. TestMap lists every element that lost coverage since the last run, with its traffic, so the checkout button stands out from a footer link.
Rank every gap by what users actually do.
Plain coverage treats every element as equal. TestMap weights each one by real Google Analytics 4 traffic and sorts your gaps into four buckets: Not Tested, Under Tested, Over-Tested, Optimized. A to-do list ordered by risk — and a Test Efficiency Score from 0 to 100 that leadership can track.
Works with what you already have.
Why is code coverage misleading?
Code coverage measures execution, not verification. A line counts as covered the moment a test runs through it — asserted or not, used by real users or not. The number rises when you add tests anywhere and stays flat when a test stops clicking the one button that matters. That is how a suite reports 94% and still misses mobile checkout.
