Do you want to start testing your codebase but don't know where to start?

Unit testing can be difficult to get going, with questions like:
- How do I set up unit tests?
- What even *are* unit tests?
- How do I make an assertion? (again, what even IS an assertion!?)
- Do I use PHPUnit, Pest, or... something else?
- What is mocking?
- Oh no, I have a legacy code base and the code is pretty much untestable... What do I do now?

Oh, and we'll also cover code coverage so we're covered... 😏

We'll go through all of this and maybe a bit more.

We'll also look at refactoring a classic piece of legacy code to make it more testable.
