How to stub a view helper method?

[murphyslaw]

Hello,

I have a view helper method that is used in almost all of my cells.

class MyCell << Cell::Rails
  helper :my_helper

  def show
    ...
  end

  ...
end

module MyHelper
  def my_helper_method
    ...
  end
end

How can I stub it? I tried

controller.stub(:my_helper_method)

render_cell(:my_cell, :show)

but this doesn't work and I have no clue what to look for to find the object that the method is later called on. Do you have an idea?

A way seems to be

MyCell.view_context_class.any_instance.stub(...)

Thanks. I will close the issue, as I'm currently not working on it anymore. Your suggestion sounds good.

Reopening it - I have an idea how to fix that very easily: in the newest Cells release the way cells are constructed was simplified so it should be quite easy provide the cell instance that is then to be rendered. Thanks!

I found out that this is working already! Just do the following:

  it "renders empty posts list" do
    posts = cell(:posts)
    posts.stub(:recent_posts).and_return([])

    posts.render_state(:count).should have_selector("p", :content => "No posts!")
  end

I added this to the README: https://github.com/apotonick/rspec-cells#api

Anyone wants to format this to Markdown? :)
