Hello guys!
I have a question, currently those who work on the automatic testing that you use, POM, Builder design pattern, Factory design pattern?

[voinywolnyprod]

No need to use re, just
import string
string.punctuation

Using string methods are faster, then re.
Btw re patterns could be precompiled
