使用RSpec测试方法？ （路轨）

Question

My question is I have a module which is going back to a controller and I want to test it with RSpec but its not a class / there is no class inside the module its just a method so how would I test for example the methods return values , here is what I currently have in my module,

require 'rspec'

module LeagueModule
  module ScrapeProPlayers

    def scrape
      players = []
      return players
    end

  end
end

describe LeagueModule::ScrapeProPlayers do
  it "Check for any pro players" do
     host = Object.new.extend(LeagueModule::ScrapeProPlayers)
     host.scrape.should == 0

  end
end

Answer 1

Ok I figured it out this firstly I shouldn't of been using 'should' its better to use 'expect' and that was the wrong way of writing it :

describe LeagueModule::ScrapeProPlayers do
  it "Check for any pro players" do
     host = Object.new.extend(LeagueModule::ScrapeProPlayers)
     result = host.scrape
     expect(result.length).to eq(0)
  end
end
