I'm very new to ruby and mocking a dynamic language. I would like to mock a helper method in Sinatra. So an example is this:helper do def my_helper_method puts "Should do something useful here..." end end How would I mock that method and how would I mock a method in general that is a global method. Is it better practice not to have global methods? Should I rather have an object inside the method call that does all the work and I can mock that?
You can probably set an expectation on Kernel#puts, since although #puts looks global, it belongs to Kernel.
As for whether you should use #puts directly here, or indirectly through another object that you can easily control, that depends on the situation. Try both and compare the results.
In your situation, I'd probably just set expectations on Kernel#puts until that caused me problems, at which point I'd separate the behavior of deciding what to print from deciding where to print it. I find formatting messages much easier to check, in general, than displaying them.
