Question

I’ve wrote a class method, which calls other class methods of the same class.

class Statistic
  def self.do_something
    #...
  end

  def self.update_statistic
    Statistic.do_something
  end
end

How do I test, that update_statistic calls do_something?

I use Rails 3 & rspec 2.

Answer 1

You should be able to set an expectation on do_something and then call update_statistic directly.

Statistic.should_receive(:do_something)
Statistic.update_statistic
