RSpec ignoring Turbo delete method

Question

I have a link to delete a resource in a Rails app that works fine during manual testing but I cannot make the RSpec test for it pass. The link uses Turbo. It looks like the tests are ignoring the turbo-method, as I get the error:

Failures:

I have tried adding js: true but this doesn’t seem to make any difference.

RSpec

feature 'user deletes a kalendar' do
  let!(:kalendar) { create :kalendar }

  scenario 'successfully' do
    sign_in kalendar.user
    visit user_path(kalendar.user)
    expect { click_on 'Remove calendar' }.to change { Kalendar.count }.by -1
    expect(page).to have_content("#{kalendar.name} has been removed")
  end
end

The view

      <li>
        <strong><%= kalendar.name %></strong>
        <%= link_to "Remove calendar", kalendar_path(kalendar), data: { "turbo-method": :delete } %>
      </li>
