Checking for the presence of an input field with Capybara

Lets say I have the following form field:

<%= simple_form_for @page do |f| %>
  <%= f.input :name, label: false, placeholder: "Name" %>
  <%= f.button :submit %>
<% end %>

How can I test it's presence?

The following says no matches were found:

it { should have_field("name")}

Also tried "page[name]", which is the name given to the field in HTML, but then RSpec gives me this error:

it { should matcher }

RSpec expects the matcher to have a #description method. You should either add a String to the example this matcher is being used in, or give it a description method. Then you won't have to suffer this lengthy warning again.

Is it the square brackets that cause this? Thanks in advance.

What that message is saying is you are missing a description string for the example, which is because you only have it { should have_field("name")}

Update your example as follows: 

it 'has name input field' { should have_field("page[name]")}

If you have multiple examples that may fall under same group then you can use describe with it as:

describe 'Page form' do 
  it 'has name input field' { should have_field("page[name]")} 
  it ... { ... }
end

Please reference Better Specs for other suggested best practices in working with RSpec.

Providing that page is a subject:

it { should have_selector("form input[name='page[name]']") }
