I get some deprecation warnings during testing. How can I fix that?

I got this warning: 

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
      end

(Called from /home/tomasz/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/capybara-2.1.0/lib/capybara/rspec.rb:20:in `block (2 levels) in <top (required)>')
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------

My question is how can I fix that?

My example test looks like that:

    it "displays an error when todo list have no description" do
        expect(TodoList.count).to eq(0)

        visit "/todo_lists"
        click_link "New Todo list"
        expect(page).to have_content("New todo_list")

        fill_in "Title", with: "Grocery list"
        fill_in "Description", with: ""
        click_button "Create Todo list"

        expect(page).to have_content("error")
        expect(TodoList.count).to eq(0)

        visit "/todo_lists"
        expect(page).to_not have_content("Grocery list")
    end

Here's another forum post from 4 months ago that may be useful to you: https://teamtreehouse.com/forum/how-do-i-removed-these-depreciation-warnings

Sorry I don't know more about the issue.
