RSpec Mock Object Example

Question

I am new to mock objects, and I am trying to learn how to use them in RSpec. Can someone please post an example (a hello RSpec Mock object world type example), or a link (or any

Answer 1

I don't have enough points to post a comment to an answer but I wanted to say that the accepted answer also helped me with trying to figure out how to stub in a random value.

I needed to be able to stub an object's instance value that is randomly assigned for example:

class ClumsyPlayer < Player do

  def initialize(name, health = 100)
    super(name, health)
    @health_boost = rand(1..10)
  end
end

Then in my spec I had a problem on figuring out how to stub the clumsy player's random health to test that when they get a heal, they get the proper boost to their health.

The trick was:

@player.stub!(health_boost: 5)

So that stub! was the key, I had been just using stub and was still getting random rspec passes and failures.

So thank you Brian
