[Solved] Ruby on rails tutorial – integration test – valid/invalid user info sign failing – user_param issue?

I think you should remove params key before user parameters, e.g.:

test "invalid signup information" do
  get signup_path
  assert_no_difference 'User.count' do
    post users_path, user: { name:  "",
                             email: "user@invalid",
                             password: "foo",
                             password_confirmation: "bar" }
  end
  assert_template 'users/new'
  assert_select 'div#error_explanation'
  assert_select 'div.field_with_errors'
end

Also you can debug received parameters in controller with pry:

  • add gem pry to your Gemfile (if there is no one);
  • run $ bundle install;
  • add binding.pry in controller before method user_params is called;
  • check that params contains expected parameters.
