Is there any point in the globals or “evil” monophonic

Question

I previously used Singletons for global classes, if absolutely necessary, that is, a log, error handling. But now I use unit testing that they don’t like!

I would like to ask a basic question about global signs. What is the point of them? What happened to creating a new instance of the class when you need it?

Answer 1

It’s true, sometimes singletones can create problems that you won’t have without them.
