What is the exact error? It always shows you which line, what it expected and what it got.

This is not the full error. Please copy everything from your console from the moment you entered rspec until the next prompt. You may have to scroll up for that.

Deprecation Warnings:

--------------------------------------------------------------------------------
RSpec::Core::ExampleGroup#example is deprecated and will be removed
in RSpec 3. There are a few options for what you can use instead:

  - rspec-core's DSL methods (`it`, `before`, `after`, `let`, `subject`, etc)
    now yield the example as a block argument, and that is the recommended
    way to access the current example from those contexts.
  - The current example is now exposed via `RSpec.current_example`,
    which is accessible from any context.
  - If you can't update the code at this call site (e.g. because it is in
    an extension gem), you can use this snippet to continue making this
    method available in RSpec 2.99 and RSpec 3:

      RSpec.configure do |c|
        c.expose_current_running_example_as :example

If you need more of the backtrace for any of these deprecations to
identify where to make the necessary changes, you can configure
`config.raise_errors_for_deprecations!`, and it will turn the
deprecation warnings into errors, giving you the full backtrace.

OK, so as you can see here:

Unable to find css "#todo_list_1"

It isn't able to find the proper css element, the problem is not with .reload. Run the server, go to the browser and make sure you can find such element in the page source code. Also, please post the code for the index view, Maybe it will tell us something.
