I think we are going a bit off topic, by the way: 1. Symplify/CodingStandard takes `'Class'` string, asserts that is a real class with `*_exists()` functions or with a regex,...

Yes, we could re-use a lot of PHP-CS-Fixer code in a new PHP-CS-Fixer+PHPUnit test component/plugin, in order to have checks/sniffs that are content-aware, because test suites are by definition content-aware.

@Jean85 yup, this can be a solution, making the `vendor/autoload.php` option path mandatory for this Fixer. Reminder: if we are going to do so, after requiring the autoload it should...

Other two points came to my mind: 1. Alongside `ComposerAutoloaderInit` and `composerRequire` there also is `ComposerStaticInit` but has the exact same implication, so no issue 1. If instead of being...
