Helper Methods - Help!

Rails
1

How can I call a helper method standalone, that is, not within a
controller or anything? For instance, let’s say I have a class - not a
subclass of ActiveAnything - that wants to do url_for , or the like?

The reason I am asking is that I want to create UNIT tests for my
helper methods, but can’t get them to work. I can’t figure out how to
invoke them outside of templates or controllers.

Am I the only one that has thought to unit test my helpers? How does
everyone else do it?

There was some discussion of this a little while ago.

You don’t need to unit test your helpers. Helpers are like private
methods, they’re arrived at by extraction.

If you write a view, and your tests pass. Then when you extract the
functionality to a helper, if your tests still pass, then you’ve
extracted properly.
