Consider moving tests outside of src/

[Wojciechem]

A pretty standard practice for libraries is to have two directories at the root:

• src/
• tests/

and include tests only in autoload-dev.

This also allows to exclude tests from "dist" library, using .gitattributes with tests/ export-ignore - making it a bit more lightweight - great for production use.

@Wojciechem Thanks for creating first issue in my repo :-). Your suggestion sounds legit. Could you please confirm that you're talking about something like that: https://madewithlove.com/blog/software-engineering/gitattributes/ ?

@Wojciechem I am not an expert on .gitattributes. Could you please review my PR or tell how to properly test this change?

[Wojciechem]

@michalbiarda Yes, the article summarizes it well.
I'm no expert either, literally used .gitattributes once, just for this use-case :) but yours looks fine.
Github will generate zip archive - "release" for tag, the export-ignored files should not be present - that's it :)

Thanks @Wojciechem 👍. I merged it at it worked just fine :-).
