Rspec and Capybara uninitialized constant - ruby

Question

I am using Rspec 3.2 and Capybara 2.4 in a non RoR project. I am trying to test with feature mode provided by Capybara gem.
$ cat .rspec
--color
--require spec_helper
$ cat spec/features/test_spec.rb
feature 'login' do
username ="rspec#{Time.now.to_i}"
valid_email = "#{username}#gmail.com"
scenario 'with valid email' do
sign_up_with valid_email, 'pwd', 'pwd', username
expect(page).to have_content('LOGOUT')
end
end
$ cat spec/support/session_helper.rb
module SessionHelper
def sign_up_with(email, password, confirm_password, username)
visit '/signup'
fill_in 'email', with: email
fill_in 'password', with: password
fill_in 'passconf', with: confirm_password
fill_in 'username', with: username
click_button 'submit'
end
end
$ cat spec/spec_helper.rb
require 'capybara/rspec'
Capybara.default_driver = :selenium
RSpec.configure do |config|
...
config.include SessionHelper, type: :feature
...
end
This is a non RoR project, when I run the test I have this error:
$ rspec
spec/spec_helper.rb:26:in `block in <top (required)>': uninitialized constant SessionHelper (NameError)
In online documentation there are many examples, I have structured my files like the examples but it not works.

Answer 1

The way I handle this in all of my projects is like this:
Require all the support files:
In spec_helper.rb
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
And then your spec/support/session_helper.rb should look like this:
module SessionHelper
def sign_up_with(email, password, confirm_password, username)
visit '/signup'
fill_in 'email', with: email
fill_in 'password', with: password
fill_in 'passconf', with: confirm_password
fill_in 'username', with: username
click_button 'submit'
end
end
RSpec.configure do |config|
# Remove the equivalent line from spec_helper.rb
config.include(SessionHelper)
end
