No leftover data. No slow database resets. Clean environment every run.

We’re using it while testing mention syncing in our Laravel mentions course.

Fast tests. Clean state every run.

A small testing trick that makes Laravel tests way faster:

Use SQLite in-memory during test runs.

Before adding comment editing, we’re locking down mention syncing with Pest and an SQLite in-memory test DB.

When you’re building something like @mentions, tests matter more than you think.

This week’s topic on Code Course: testing mention syncing in Laravel.

We’ve been talking about caching authenticated users all week.

But do you actually understand what’s happening?

Full video + quiz is live.

Go test yourself: zurl.co/VzQWP

If the user hasn’t changed,
why are you re-fetching them 100 times?

Caching isn’t about Redis hype.

Laravel’s default Eloquent driver
will fetch the authenticated user
on every request.

So we replaced it.

Check out the full Snippet here:

zurl.co/djOjM

Start with the authenticated user query.

Then decide what deserves caching.

If your comments, likes, and attachments
all have separate schemas…

You missed the abstraction.

Hot take:
If polymorphic relationships confuse you,
you’re probably overbuilding your schema.
