I would go further and say that you should never trust code reviews to catch bugs.  They&#x27;re great for all the reasons in the article and what &quot;zhemao&quot; said but they&#x27;re horrible for catching any bugs beyond the most trivial ones.  Humans simply aren&#x27;t good at running code in their head like that.  Code review is no substitute for good code coverage and automated testing, preferably pre-commit.
