How to connect phpunit 8+ without composer autoloader?

Question

PHP

I realized my insignificant knowledge in php, I decided to write my own microframework for learning.
I specifically do not use the autoloader from composer.
I have not written my own yet (due to insignificant knowledge).
Therefore, the following question arose:
how to connect phpunit 8+ without the composer autoloader?

Answer 1

Yes, he is good, do not refuse. The loader then only searches for classes in files and that's it. No, you will have to require class.php in the loader ... but the eggs in the profile will be the same.
There, under the hood, spl autoload register and a complete list of all files in a cached form, otherwise no magic
