This article is an example of the straw-man fallacy , binary thinking fallacy and other inconsistencies. The title is click bait. At most you can say: "Code Coverage alone is not a sufficient metric for software quality"

There are many other things lacking in this article making is not a balanced analysis of code-coverage
