Question

I’m building an app while following a tutorial in the book Simply Rails 2 and am having trouble getting some tests to pass.

Here are the errors I’m receiving:

  1) Failure:
test_should_show_index(StoriesControllerTest)
[/Users/ryanclark/Projects/shovell/test/functional/stories_controller_test.rb:8:in `test_should_show_index'
 /Users/ryanclark/.rvm/gems/ruby-1.8.6-p420/gems/activesupport-2.0.2/lib/active_support/testing/default.rb:7:in `run']:
<nil> expected to not be nil.

  2) Failure:
test_should_show_navigation_menu(StoriesControllerTest)
[/Users/ryanclark/.rvm/gems/ruby-1.8.6-p420/gems/actionpack-2.0.2/lib/action_controller/assertions/selector_assertions.rb:297:in `assert_select'
 /Users/ryanclark/Projects/shovell/test/functional/stories_controller_test.rb:44:in `test_should_show_navigation_menu'
 /Users/ryanclark/.rvm/gems/ruby-1.8.6-p420/gems/activesupport-2.0.2/lib/active_support/testing/default.rb:7:in `run']:
Expected at least 2 elements matching "#navigation li", found 3.
<false> is not true.

  3) Failure:
test_should_show_new_form(StoriesControllerTest)
[/Users/ryanclark/.rvm/gems/ruby-1.8.6-p420/gems/actionpack-2.0.2/lib/action_controller/assertions/selector_assertions.rb:297:in `assert_select'
 /Users/ryanclark/Projects/shovell/test/functional/stories_controller_test.rb:18:in `test_should_show_new_form'

Expected at least 3 elements matching "form p", found 4.
<false> is not true.

My project is on Github and I would really appreciate a little insight if someone would take a look and help me out.

Also, I’m happy to provide more details and code, just trying to keep the post short.

Answer 1

Failure 1: In test ‘test_should_show_index’ at line 8 assert_not_nil assigns(:stories).

You have no stores with ‘votes_count >= 5’ in your test database. Here is your fixture for Stories (stories.yml):

one:
  name: My shiny weblog 
  link: http://poocs.net
  user: patrick

two:
  name: SitePoint Forums
  link: http://www.sitepoint.com/forums/
  user: patrick 

All stories have default value for votes_count (it is 0, see db/schema.rb, line 20). You need at least one story to have votes_count >= 5, thus change fixture to something like this:

one:
  name: My shiny weblog 
  link: http://poocs.net
  user: patrick

two:
  name: SitePoint Forums
  link: http://www.sitepoint.com/forums/
  user: patrick 
  votes_count: 5

Failure 2: In test ‘test_should_show_navigation_menu’ at line 44 assert_select '#navigation li', 2

Your navigation div has 3 child <li> tags instead of 2 expected (see application.html.erb):

<ul id="navigation">
    <li><%= link_to 'Front page stories', stories_path %></li>
    <li><%= link_to 'Upcoming stories', bin_stories_path %></li>
    <li><%= link_to 'Submit a new story!', new_story_path %></li>
</ul>

Failure 3: In test ‘test_should_show_new_form’ at line 18 assert_select 'form p', :count => 3.

Your form contains 4 <p> tags instead of 3 expected. You can find it inside your template for ‘new’ action method (new.html.erb):

<% form_for(@story) do |f| %>
  <p>
    <b>Name</b><br />
    <%= f.text_field :name %>
  </p>

  <p>
    <b>Link</b><br />
    <%= f.text_field :link %>
  </p>

    <p>
        description:<br />
        <%= f.text_area :description %>
    </p>

  <p>
    <%= f.submit "Create" %>
  </p>
<% end %>

Hope this helps.
