Capybara 3 has changed the page.has_text? method that is used e.g. by the I should (not) see … steps to respect white space, including \n. This breaks tests that rely on the previous behavior, which normalized all white space like Rails' squish.

Fortunately, the has_text? method takes options and passes them to assert_text. This method takes a :normalize_ws option that restores the previous behavior if set to true:

An update for the I should see … steps could look like this:

patiently do
  expect(page).to have_text(text, normalize_ws: true)
end
