How do I assert the unexistance of a model in Cucumber?

How do I assert that a user was not created while using Cucumber? In RSpec, I would use the following block, which I can not translate to Cucumber:

...
describe "with invalid information" do
  it "should not create a new user" do
    expect { click_button submit }.not_to change(User, :count)
  end
end

# Cucumber equivalent
When /^he submits invalid information$/ do
  click_button "Sign up"
end
Then /^an account should not be created$/ do
  # not sure how to translate the expect block
end

You can use a lambda to directly translate your RSpec test, rather than rely on a workaround.

Then /^an account should not be created$/ do
  save = lambda { click_button :submit }
  expect(save).not_to change(User, :count)
end

You could also do

Given I have 3 users
When I submit with invalid information
Then I should have 3 users

In this example, you'll know the email that the user would use, so you could:

Then /^an account should not be created$/ do
  User.where(email: "[email protected]").first.should be_nil
end
