RSpec2MiniTest

Provides a generic factory to automatically convert the RSpec matchers of your favorite gems into assertions and expectations for MiniTest::Unit and MiniTest::Spec. It is a generalization of Jared Ning's capybara_minitest_spec.

Installation

# Gemfile
gem 'rspec2minitest'

Integrations

Capybara

To create assertions / expectations from all Capybara RSpec matchers add to your test_helper:

require 'rspec2minitest/capybara'

For the have_text matcher you can then use:

# Unit
assert_page_has_text(page, text)
refute_page_has_text(page, text)

# Spec
it { must_have_text(text) }
it { wont_have_text(text) }

For all matchers see Capybara/RSpecMatchers

This is exactly what the capybara_minitest_spec gem does. If Capybara matchers are the only ones you need to convert, I recommend using that gem.

Paperclip

# test_helper
require 'rspec2minitest/paperclip'

The have_attachment matcher gets converted to assert_model_has_attachment and must_have_attachment and their negative counterparts.

For all matchers see Paperclip::Shoulda::Matchers

Custom integrations

You can use the API of rspec2minitest to easily create your own integrations within your test_helper. require 'rspec2minitest' provides you with an RSpec2MiniTest module that provides an add_matcher function to convert single matchers and an add_matchers function to convert all public instance methods of a given module.

Have a look at the integrations in lib/rspec2minitest for examples and do not forget to issue a pull request to add lib/rspec2minitest/#{gemname}.rb to the rspec2minitest spec. :)
