Failure of index.html.erb_spec

After running bin/rake I've encountered a failure described as follows

1)  todo_lists/index renders a list of todo_lists
     Failure/Error: assert_select "tr>td", :text => "MyText".to_s, :count => 2
       <MyText> expected but was
       Expected: 2
         Actual: 0
     # ./spec/views/todo_lists/index.html.erb_spec.rb:21:in `block (2 levels) in <top (required)>'

Here is a sample of my index.html.erb_spec.rb

describe "todo_lists/index" do
  before(:each) do
    assign(:todo_lists, [
        :title => "Title",
        :description => "MyText"
        :title => "Title",
        :description => "MyText"

  it "renders a list of todo_lists" do
    # Run the generator again with the --webrat flag if you want to use webrat matchers
    assert_select "tr>td", :text => "Title".to_s, :count => 2
    assert_select "tr>td", :text => "MyText".to_s, :count => 2

Here is a sample of the code in my index.html.erb

    <% @todo_lists.each do |todo_list| %>
      <tr id="<%= dom_id(todo_list) %>">
        <td><%= todo_list.title %></td>
          <%= link_to "List Items", todo_list_todo_items_path(todo_list) %>
          <%= todo_list.description %>
          <%= link_to 'Show', todo_list %>
          <%= link_to 'Edit', edit_todo_list_path(todo_list) %>
          <%= link_to 'Destroy', todo_list, method: :delete, data: { confirm: 'Are you sure?' } %>
    <% end %>

Any help would be appreciated in solving this issue! Thanks.

Hi Robert, Are you using RSpec? I am not sure if your spec file is named correctly. I use the naming convention my_test_abc_spec.rb, so there is only only dot in the name. Also I run my tests like this:

rspec path/to/file/my_test_abc_spec.rb 

if I only want to test that specific file.
