Makes perfect sense now, thank you for the help, great explanation of the fix as well, I honestly didn't realize it was case sensitive like that but I now I see, once i changed

<pre><code>fill_in "Title", with: "My todo list"</code></pre>

to

<pre><code>fill_in "Title", with: "My Todo list" </code></pre>

it worked perfect!

Thank you very much!

And nothing more? Perhaps this: "New Todo list" should be "New Todo List" (open the browser and see what the button really says on that page).

this is what it looks like on the default page, that i setup in the routes.rb file

Listing todo_lists

Title Description

New Todo list

OK, but your error is probably longer and tells you exactly which expectation fails, what it expected and what it got instead. This would help a lot.

your right this is the entire error, I somehow must have overlooked the top section

ฮป rspec spec\features\todo_lists\create_spec.rb F

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

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 you are doing this:

fill_in "Title", with: "My todo list"

and expecting this:

expect(page).to have_content("My Todo list")

You have to change the letter to capital in the fill_in or make it lower case in the expect.

one more question for you what markdown did you use for showing the above examples? Do you have a link to the source? I have tried the 3 backticks with Ruby () and others just cant find itThanks Very much!

You can simply copy them from the Markdown Cheatsheet or use the ones on the left side of the keyboard, above the Tab, before the 1 key. You just write three ticks, the word ruby without any spacer or parentheses and write the code in the next line. And then close the code in the separate line. You should also have an empty line before the three ticks and ruby and after the closing three ticks.
