Undefined method validate_uniqueness_of error on sinatra app

[lucasdavila]

Hey guys!

I'm testing a sinatra app, I can use the validate_presence_of matcher without problem, but the validate_uniqueness_of is failing.

I already tried to:

• Take a look in the issues #203 and #552
• require all needed gems manually.
• put require: false on Gemfile, and require shoulda/matchers on the spec_helper.
• configure the Gemfile exactly like the Readme file (without the require: false).

None of these attempts worked 😿 Do you have any idea about what could be misconfigured?

Thank you.

Here is my gems versions:

Here is my Gemfile:

source "https://rubygems.org/"

gem 'sinatra'

gem 'pg'
gem 'activerecord'
gem 'sinatra-activerecord'

gem 'activesupport'

group :test do
  gem 'rspec'
  gem 'shoulda-matchers', github: 'thoughtbot/shoulda-matchers'
end

group :development do
  gem 'rake'
  gem 'sinatra-contrib'
end

Here is my spec_helper:

ENV['RACK_ENV'] = 'test'

Bundler.require :default, :test

Shoulda::Matchers.configure do |config|
  config.integrate do |with|
    with.test_framework :rspec

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

RSpec.configure do |config|
  config.expect_with :rspec do |expectations|
    expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end

  config.mock_with :rspec do |mocks|
    mocks.verify_partial_doubles = true
  end
end

Here is the complete log:

I'm closing this issue since I submitted it in the wrong repo, I will submit it again on thoughtbot/shoulda-matchers.
