Why Testing Should Always Be at the Top of Your Development List

After 20+ years of coding, I made one small change… and it quietly broke over 160 pages on my website.

The worst part?
The pages were still on the server.
But users were getting 404 errors for months — and I didn’t notice.

This video is a real developer lesson on why testing should always be at the top of your development process, especially when running a custom CMS built with Node and MongoDB.

I explain:

How a single typo caused cascading 404 errors

Why “quick manual checks” are not real testing

The hidden SEO damage from unnoticed bugs

How I used AI to build automated testing safeguards

Why startups and solo developers are most at risk

If you ship fast, iterate often, or run your own bespoke system, this is a mistake you only want to learn from once.

Because bugs don’t forgive.
And they are always one change away.
