Question

I have following code like this in ‘artists_helpers’ class.

def round_to(x)
  (self * 10**x).round.to_f / 10**x
end

Similarly, in the artist_helper_spec.rb, I have code like this.

describe ArtistsHelper do
  it "should return a two digits after decimal" do   
    mock=12.234
    mock.round_to(2).should == 12.23
  end
end

How do I write script to make this function to test.

The problem is that, I dont get value of ‘:self’ variable in helpers, when running rspec test.

Is their any other links which are helpful ?

Answer 1

ArtistHelper.round_to(2).should == 12.23
