Recommendations for writing view index spec for a resource which behaves differently for different u

Testing RSpec
1

hi guys,

In my index view specs for a given resource, I have successfully
written it for admin users.

For the given resource, when admin users are looking at the index
page, they should see
-a link to add a new resource object
-links to delete/edit/show for each resource object created

My index view specs does this perfectly and it reads:

------- file: begin -----------------------

192-168-1-4:categories anexiole$ cat index.html.erb_spec.rb
require ‘spec_helper’

describe “categories/index.html.erb” do
before(:each) do
view.stub(:is_admin).and_return(true)

assign( :categories, [
FactoryGirl.create(:category_intakes),
FactoryGirl.create(:category_audio),
]
)
end

it “renders a list of categories” do
render
assert_select ‘tr>td’, :text => ‘intakes and filters’.to_s, :count
=> 1
assert_select ‘tr>td’, :text => ‘audio’.to_s, :count => 1
end

it ‘renders an interface with the new link’ do
render
rendered.should contain (‘New Category’)
end

end

------- file: end -----------------------

Now, I would then like to put more specs in the index view spec.

When a non-admin user (ie someone who has not logged in) looks at the
index page, the user
should NOT see
-a link to add a new resource object
-links to delete/edit/show for each resource object created

  1. How can I best write this?
  2. Would using “:let” before each different spec (admin and non-admin)
    be a good way to do it?

thank you :slight_smile:

^^ I’ve been in the habit of using view.stub(:is_admin => true).

Also, the Ruby idiom for questions like “is this being viewed by an
admin” is a Ruby predicate - a method name with a question mark at the
end:

view.stub(:admin? => true)

Names like is_admin are usually holdovers from Java :slight_smile:

assert_select ‘tr>td’, :text => ‘audio’.to_s, :count => 1
^^ ‘intakes and filters’ and ‘audio’ are already strings, so you don’t
need .to_s.

  1. How can I best write this?

Best is subjective. One way you can write it is:

context “viewed by a non-admin” do
before do
view.stub(:admin? => false)
# set up assigns
end
it “should not see xxx” do
render
assert_select selector, … :count => 0
# or, if you’re using Capybara
rendered.should_not have_tag(selector)
end
end

  1. Would using “:let” before each different spec (admin and non-admin)
    be a good way to do it?

let() is for creating objects, which is not what you’re doing here -
you’re simulating different logins. I’d stick with stubbing :admin? in
the before declaration.
