🔗 Treat test code like production code

You have to read and maintain test code, too.

I don't think I've previously published an article with the following simple message, which is clearly an omission on my part. Better late than never, though.

Treat test code like production code.

You should apply the same coding standards to test code as you do to production code. You should make sure the code is readable, well-factored, goes through review, etc., just like your production code.
