I'm learning how to do integration testing in a simple Rails application using Capybara.
However, an error occurred while starting the 'rspec spec':
bundle exec rspec spec

My gemfile (partial):
group :test do
gem 'fake'
gem 'capybara'
gem 'database_cleaner'
gem 'launchy'
end
group :development, :test do
gem 'rspec-rails'
gem 'factory_girl_rails'
gem 'guard-rspec'
gem 'growl'
gem 'dotenv-rails'
end
My test case (location: /spec/features/users_spec.rb):
require 'spec_helper'
describe 'User authentication' do
context 'new user signs up' do
it "saves the new user" do
visit "/"
expect {
click_button 'Sign up'
fill_in 'Name', with: 'alexjiao'
fill_in 'Email', with: "alexjiao@yahoo.com"
fill_in 'Password', with: 'asdfasdf'
fill_in 'Password confirmation', with: 'asdfasdf'
click_button 'Create my account'
}.to change(User, :count).by(1)
end
end
end
My spec_helper.rb (location: /spec/spec_helper.rb):
require 'capybara/rails'
require 'capybara/rspec'
RSpec.configure do |config|
config.include Capybara::DSL
end
Here you can find several solutions, such as installing a test case in the function folder and creating a config statement for capybara DSL. But I can’t get the capybara to work. It seems that my situation is a bit unique, especially with the error message above. It should be noted that after starting rails g rspec:installmine is spec_helper.rbempty (is this normal?). Therefore, this explains its short code above.
Any thoughts?
