ApplicationHelper

Testing RSpec
1

When working with views, I use instance methods of ApplicationHelper:

app/helpers/application_helper.rb:

module ApplicationHelper
def distribute(total, min, cutof, list)
[1,2,3]
end
end

app/views/planner/_mta_colors.rhtml:

<% ... dist = distribute(total_v_px, 4, 0, colors.collect{|color| color[1]}) ... %>

So to test the distribute method in ApplicationHelper, I have to extend
my
spec models:
describe ApplicationHelper do
extend(ApplicationHelper)
it "doesn’t find what it’s looking for do
distribute(1,2,3,[4,5,6]).should eql([1,2,3])
end
end

This could use some documentation.

You could just write specs for ApplicationHelper::distribute

If I need to have it interact with the object it is mixed into, I
usually
put the following above my examples

class TestMixer
include MyMixIn
end

or, even,

class TestMixer
end

then, in the spec,

TestMixer.include MyMixIn

That shouldn’t be needed. In my spec’s it works fine. does:

describe ApplicationHelper do
it "doesn’t find what it’s looking for do
helper.distribute(1,2,3,[4,5,6]).should eql([1,2,3])
end
end

work? I know that there was some talk of introducing an explicit
helper object on the list.
