minitest-metadata

• Source code: https://github.com/wojtekmach/minitest-metadata
• API reference: http://rubydoc.info/github/wojtekmach/minitest-metadata/master/frames

Description

minitest-metadata allows you to set metadata (key-value) for your test cases so that before and after hooks can use them.

You can use it to:

• change environments (prepare drivers, mocks etc)
• mark tests as slow, fast or (God forbid) order dependant

Example

require 'minitest/autorun'
require 'minitest-metadata'

describe 'thing' do
  it 'does stuff', vcr: true do
    puts metadata[:vcr] # => true
  end
end

Example with capybara

Suppose you want to tag some of your Capybara acceptance tests to use JavaScript driver

class AcceptanceTest < MiniTest::Spec
  include Capybara::DSL

  before do
    if metadata[:js] == true
      Capybara.current_driver = Capybara.javascript_driver
    end
  end

  after do
    Capybara.current_driver = Capybara.default_driver
  end
end

class UsersAcceptanceTest < AcceptanceTest
  it "basic pagination" do
    visit "/users"
    assert page.has_content?("Current page: 1")

    click_link "Next page"

    assert page.has_content?("Current page: 2")
  end

  it "keyboard shortcuts pagination", :js => true do
    visit "/users"
    assert page.has_content?("Current page: 1")

    press_key "n"

    assert page.has_content?("Current page: 2")
  end
end

As in RSpec, more compact syntax can be used:

it "keyboard shortcuts pagination", :slow, :wip, :driver => :poltergeist

Note about speed

minitest-metadata adds some overhead so you might want to limit it to only acceptance specs. If that's the case do this:

# Gemfile

group :test do
  gem 'minitest-metadata', :require => false
end

# test/acceptance_test_helper.rb
require 'minitest/metadata'

class AcceptanceTest < MiniTest::Spec
  include MiniTest::Metadata
end

Requirements

• minitest

Instalation

gem install minitest-metadata

or put in a Gemfile:

gem 'minitest-metadata'
