Setup

unset HOST
export API_SECRET_TOKEN=whatevercomestoyourmind

Integrationtest

place a save_page or screenshot before running the test
`open tmp/capybara

Run a Minitest

run a mini-test-file

cd backend
bundle exec rake test TEST=test/functional/bl/backend/products_controller_test.rb

run a single mini-test

bundle exec rake test TEST=test/functional/bl/backend/products_controller_test.rb TESTOPTS="--name=test_product_edit_redirect -v"

run a folder of files

rake test TEST=test/features/foobar/*.rb

run a nested folder of files

rake test TEST=test/features/**/*.rb

Assert a Minitest

expect redirect

assert_response :redirect

Write a Minitest

point to controller name-space

class AuthorizedUserTest < ActionController::TestCase
  tests Bl::Backend::ProductsController
end

set a scope in minitest

rmodule Bl
  module Backend
    module ProductsControllerTest
      class AuthorizedUserTest < ActionController::TestCase
        tests Bl::Backend::ProductsController

        def setup
          authorized_user = create(:superadmin)
          sign_in :bl_user, authorized_user
        end
      end
    end
  end
end

Stub a Mailer in a functional test

def test_confirm_producttests_use_producttest_participation_mailer
 producttest = create(:producttest)
 user = create(:user, notify_me: true)
 r = create(:participation_request, user: user, group: producttest)

 object = stub(confirm: true)
 Bl::Backend::ProducttestParticipationRequestMailer.expects(:delay_for).returns(object)
 bl_put :confirm, user_id: r.user.id, request_id: r.id
end

sequence provides subsequent row of numbers for the sake of ununiq data-sets

FactoryGirl.define do
  factory :um_user, parent: :user do
    sequence :um_account_number do |n|
      12345 + n
    end
  end
end

Stub a Constant

minitest-stub-const

module Foo
  BAR = :original
end

Foo.stub_const(:BAR, :stubbed) do
  Foo::BAR
end
# => :stubbed

Foo::BAR
# => :original
