Feature: generator with shell prompts spec
Generator specs live in spec/generators. In order to access
the generator's methods you can call them on the "generator" object.
Background: A simple generator
Given a file named "lib/generators/awesome/lamest_generator.rb" with:
"""
class LamestGenerator < Rails::Generators::NamedBase
source_root File.expand_path('../templates', __FILE__)
class_option :super, :type => :boolean, :default => false
def create_lamest
@lame = false
@awesome = false
@user_name = ask("What is your name?")
if yes?("Are you the lamest?")
@lame = true
end
if yes?("Are you awesome?")
@awesome = true
end
template 'lamest.html.erb', File.join('public', name, "#{"super_" if options[:super]}lamest.html")
end
end
"""
And a file named "lib/generators/awesome/templates/lamest.html.erb" with:
"""
<%= @user_name %> <%= "is the lamest" if @lame %> and <%= "is not awesome!" if @awesome == false %>
"""
Scenario: A spec that runs the entire generator
Given a file named "spec/generators/lamest_generator_spec.rb" with:
"""
require "rails_helper"
require 'generators/awesome/lamest_generator'
describe LamestGenerator do
describe 'invoke' do
before do
gen = generator %w(my_dir)
set_shell_prompt_responses(gen, { :ask => "Thomas", :yes? => [true, false] })
run_generator
end
describe 'public/my_dir/lamest.html' do
subject { file('public/my_dir/lamest.html') }
it { expect(subject).to exist }
it { expect(subject).to contain 'Thomas is the lamest and is not awesome!' }
it { expect(subject).to_not contain 'This text is not in the file' }
end
end
end
"""
When I run `rake spec`
Then the output should contain "3 examples, 0 failures"
