The Complete Next.js Testing Course

Master Production Ready Testing in Only One Course… the only thing standing between you and senior developer roles.

Stop gambling with every deployment.
Here’s a little known fact.

Only 1 in 4 Next.js developers write production-ready tests.

The other 3? They deploy and pray.

So who’s the one? What companies do they work for?
Take a look.

The best devs have already realized they need to test their apps or get left behind.

Here’s the catch.

My team and I and these massive companies don’t just write tests.
We write tests that actually catch bugs.

If you try testing Next.js 16 like plain React, you’ll write weak tests that break with every refactor and miss the real bugs.

That’s because you’re taught that…

“Testing is just writing a few unit tests”

Wrong. Testing is an iceberg.

You think you know it because you only see the 15% of it that’s above water.

So you write some tests. Get 80% coverage. Feel safe.

Like the Titanic hitting an iceberg that seemed tiny, what you skip testing sinks you.

The same thing happened to me.

I was looking for a good way to learn testing for a long time, but I couldn’t find anything.

Every tutorial I came across was basic. It didn’t teach me production patterns.

Most of the people teaching testing have no experience maintaining test suites for massive apps in prod – so they give superficial advice (if the advice is up to date at all).

You don’t want to read the never-ending docs or 7,153 articles to learn it all.

So I spent 9 months deep into testing.

Building massive 5 and 6-figure apps with comprehensive test suites.

Testing real production features – authentication, databases, AI integrations.

Rebuilding test architectures from scratch for apps that had zero test coverage.

After all this? I kept getting daily requests to make a testing course. I’m finally doing it.

Here’s a three-part testing method so you don’t have to struggle.
