Ruby unittest error: "you should require 'minitest/autorun' instead." - ruby

I have a very simple unit test that I copied from http://en.wikibooks.org/wiki/Ruby_Programming/Unit_testing.
require_relative "simple_number"
require "test/unit"
class TestSimpleNumber < Test::Unit::TestCase
def test_simple
assert_equal(4, SimpleNumber.new(2).add(2) )
assert_equal(6, SimpleNumber.new(2).multiply(3) )
end
end
Executing this code causes error:
Warning: you should require 'minitest/autorun' instead.
Warning: or add 'gem "minitest"' before 'require "minitest/autorun"'

What might be wrong?

Test::Unit::TestCase is deprecated in favor of Minitest::Test. If you want your example to work you need to change a few things:
replace require "test/unit" with require "minitest/autorun"
replace Test::Unit::TestCase with with Minitest::Test

Sinatra rspec capybara: "rack test requires a rack application"

We've tried requiring the spec_helper file in our feature test, and also requiring our app.rb in the feature test and we get a different error saying it cannot load sinatra-base
Here is our spec_helper
ENV['RACK_ENV'] = 'test'
require File.join(File.dirname(__FILE__), '..', 'app.rb')
require 'capybara'
require 'capybara/rspec'
require 'rspec'
Capybara.app = Battle
RSpec.configure do |config|
config.include Capybara::DSL
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
Any direction would be massively appreciated.
Thanks
Russ
Have a look here:
http://recipes.sinatrarb.com/p/testing/rspec
It suggests, among other things, adding the following to your spec_helper.rb:
module RSpecMixin
include Rack::Test::Methods
def app() Sinatra::Application end
end
RSpec.configure do |config|
config.include RSpecMixin
end

unable to create rake DB migration

I am trying to create a migration for a Ruby project using Sinatra. My model class is inside the app.rb file. When I run create_migration:

I get the following exception with trace:

My app.rb is copied below:
require 'rubygems'
gem 'activerecord'
require 'sqlite3'
require 'active_record'
ActiveRecord::Base.logger = Logger.new(File.open('database.log', 'w'))
#ActiveRecord::Base.logger = Logger.new(STDERR)
ActiveRecord::Base.establish_connection(
:adapter => 'sqlite3',
:host => "localhost",
:database => 'test6.db'
)
class Bill < ActiveRecord::Base
belongs_to :admin
end
class Admin < ActiveRecord::Base
validates :email, presence: true, uniqueness: true
validates :name, presence: true
has_many :bills
end
My Rakefile is copied below:
# Rakefile
require './app'
require 'sinatra'
require 'active_record'
#require 'rake'
Note: I am not using rails - I am using sinatra with activerecord
You can use sinatra-activerecord instead 'activerecord', and make minor changes like below -
in Gemfile
source 'https://rubygems.org'
gem "sinatra"
gem "pg"
gem "activerecord"
gem "sinatra-activerecord"
in rakefile.rb
require "./app"
require "sinatra/activerecord/rake"
This should work

Extending Faker gem locally uninitialized constant Faker::xxx

I want to extend the faker gem for rails to also generate other random date (in my case computer game names)
#lib/extended_faker.rb
require 'faker'
require 'extended_faker/game'
#lib/extended_faker/game.rb
Module Faker
class Game < Faker::Base
class << self
def name
fetch('game.name')
end
end
end
end
#config/locals/faker_en.yml
en:
faker:
game:
name: ["a", "b", "c"]
#config/application.rb
...
config.autoload_paths += Dir["#{config.root}/lib/**/"]
...
then when i run it in a rails console i get the following

The weird thing i don't understand is that the first time i run the generator, i get a valid result, but the second time around i get an error...
What am i missing?
you shoud put it in
lib/faker/game.rb
starting in the lib directory, rails convention is outermost module name -> in are folder names. Then the actual class/module name is the file name, underscored to the camelcase.
Another example
module Foo
module Bar
class BazParty
def self.hello
puts "hello"
end
end
end
end
would go in lib/foo/bar/baz_party.rb

"undefined method 'groups' for Rails:Module" when running "rails generate rspec:install" on Mac

Maybe it works with the following:
In config/application.rb substitute
if defined?(Bundler)
Bundler.require(*Rails.groups(:assets => %w(development test)))
end
with
Bundler.require(:default, Rails.env) if defined?(Bundler)
