Error when : rspec spec/features/todo_lists/create_spec.rb

I got an Error : .... C:\Treehouse\Project\odot (master) λ rspec spec/features/todo_lists/create_spec.rb FF

Failures:

1) Creating Todo lists redirect to the todo list index page on success Failure/Error: expect(page).to have_content("New todo_lists") expected to find text "New todo_lists" in "New Todo List Title Description Back" # ./spec/features/todo_lists/create_spec.rb:6:in `block (2 levels) in <top (required)>'

2) Creating Todo lists displays an error when the todo list has no title Failure/Error: expect(page).to have_content("New todo_lists") expected to find text "New todo_lists" in "New Todo List Title Description Back" # ./spec/features/todo_lists/create_spec.rb:19:in `block (2 levels) in <top (required)>'

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 C:/Ruby21/lib/ruby/gems/2.1.0/gems/capybara-2.1.0/lib/capybara/rspec.rb:20:in `block (2 levels) in <top (required)>')

You did the same thing I did, which is relying on the instructor to actually write passing code ( while his passes, it should not )

The line:

expect(page).to have_content("New todo_list")

should actually be:

expect(page).to have_content("New Todo List")

Hi Justin I still can't get this thing solve after make changes of what you advised me.

Failures:

1) Creating Todo lists redirect to the todo list index page on success Failure/Error: expect(page).to have_content("My Todo List") expected to find text "My Todo List" in "Todo list was successfully created. Title: My todo list Description: This is what I'm doing today. Edit | Back" # ./spec/features/todo_lists/create_spec.rb:11:in `block (2 levels) in <top (required)>'

2) Creating Todo lists displays an error when the todo list has no title Failure/Error: expect(page).to have_content("error") expected to find text "error" in "Todo list was successfully created. Title: Description: This is what I'm doing today. Edit | Back" # ./spec/features/todo_lists/create_spec.rb:26:in `block (2 levels) in <top (required)>'

Failed examples:

rspec ./spec/features/todo_lists/create_spec.rb:3 # Creating Todo lists redirect to the todo list index page on success rspec ./spec/features/todo_lists/create_spec.rb:14 # Creating Todo lists displays an error when the todo list has no title

--please help! -- What is wrong with the code.

def create_todo_list(options={})
    options[:title] ||= "My todo list" #If we do not send in title, it's going to default be My todo list
    options[:description] ||= "This is my todo list."

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

    fill_in "Title", with: options[:title]
    fill_in "Description", with: options[:description]
    click_button "Create Todo list"
  end

it "redirects to the todo list index page on success" do
    create_todo_list #you may not have gotten to the point of refactoring this part
    expect(page).to have_content("My todo list")
  end
it "displays an error when todo list has no title" do
    expect(TodoList.count).to eq(0)
    create_todo_list title: ""
    expect(page).to have_content("error")
    expect(TodoList.count).to eq(0)

    visit '/todo_lists'
    expect(page).to_not have_content("This is my todo list.")
  end

if it still fails, then it's either the html.erb file or the controller that has issues.

Thanks, Justin.

This makes sense and also worked for me.

Well, do you have capybara in your gem file? in your spec file are you requiring capybara/rspec and capybara/rails?

You can try putting include Capybara::DSL in your environment...

Aside from that I'm not sure. If none of that fixes your issues, i'm going to pull the "i'm greater than thou" response and say ditch windows and get on linux. Much easier, less headache, and it's not by microsoft... It's a 3 way win... If this site did hashtags, i'd type #microsoftsucks right about now...

But seriously, if you're using windows to develop on -- you're not a real developer.
