Test added.

Hey @jcmartineztiempo, thanks!
I couldn't pause to understand why the last test wouldn't finish, but it seems to have been fixed in recent commits.

Also, sorry for the lack of infos or support, December is usually very hectic 😅

Hi @wellwelwel,

Yeah...the last test wouldn't finish due a sql syntax error in mysql 5.7. I'll look into it later.

Don't worry about support...it's my first ever pool request!!
