How can I check that a form field is prefilled correctly using capybara?

Question

I have a field with a proper label that I can fill in with capybara without a problem:

fill_in \'Your name\', with: \'John\'

I\'d like to check

Answer 1

If the field is a hidden one with an id of 'some_field', then you can use

expect(find("input#somefield", :visible => false).value).to eq 'John'
