WebJan 1, 2013 · So how do we write a test which checks if the method is called recursively? In Ruby, we can use aliases for methods. They look like: def x puts "Hi" end alias :y :x y => "Hi" Given this, we alias our method inside our test to allow us to create the stub RSpec needs while still calling the method to kick everything off: WebRecursion is the technique of making a function call itself. This technique provides a way to break complicated problems down into simple problems which are easier to solve. Recursion may be a bit difficult to understand. The best way to figure out how it works is to experiment with it.
