Shoulda-matchers: Use Shoulda::Matchers.configure got NoMethodError

[JuanitoFatas]

Follow the README's configuration section, I got a NoMethodError when I use Shoulda::Matchers.configure in spec_helper.rb.

Can try with this demo repository to reproduce.

In this repository, I only strip all comments in Gemfile and install rspec-rails and shoulda-matchers gem:

source 'https://rubygems.org'

gem 'rails', '4.2.1'
gem 'sqlite3'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc

group :development, :test do
  gem 'byebug'
  gem 'web-console', '~> 2.0'
  gem 'spring'
  gem 'rspec-rails'
end

group :test do
  gem 'shoulda-matchers'
end

Then did:

$ rails g rspec:install
$ rails g scaffold user name

when I run the spec, bin/rspec I got:

/Users/Juan/null/shoulda-config/spec/spec_helper.rb:91:in `<top (required)>': undefined method `configure' for Shoulda::Matchers:Module (NoMethodError)

The Shoulda::Matchers configure block lives here:

require 'shoulda/matchers'

Shoulda::Matchers.configure do |config|
  config.integrate do |with|
    # Choose a test framework:
    with.test_framework :rspec

    # Choose a library:
    with.library :active_record
    with.library :active_model
    with.library :action_controller
  end
end

What is the right way to configure shoulda-matchers alone without meta shoulda gem? Thanks!!!

You've got the syntax right, but there isn't a release that contains the new configuration stuff just yet -- it's only in master. We'll probably be publishing some kind of pre-release version soon, but if you want to try it out now, you can use:

gem 'shoulda-matchers', github: 'thoughtbot/shoulda-matchers'

Got it. Thank you, Elliot.
