Typically the function has access to whatever props or state it needs because it's in the scope of the component. It's not pure, but it's rare that I need to verbosely pass props into the function call and then accept them in myFunction. I don't typically test these functions in isolation as the component itself is pure and I test the output of the component as a whole instead.

Oh gotcha, I thought this was a function that was defined outside of the component.
