Shoulda-matchers: Dependence issue with shoulda-matchers 3 and should 3.5

[olimart]

Following installation instructions and since I'm using Minitest I've added both shoulda and shoulda-matchers to Gemfile.

Bundler could not find compatible versions for gem "shoulda-matchers":
  In snapshot (Gemfile.lock):
    shoulda-matchers (3.0.1)

  In Gemfile:
    shoulda (~> 3.5) ruby depends on
      shoulda-matchers (< 3.0, >= 1.4.1) ruby

Yes, shoulda needs to be updated to support shoulda-matchers 3.x. I'll submit a PR over there. Thanks for reminding.

[mcmire]

I'm delaying this until we get all of the 3.0.0 regressions under control.

[mcmire]

In the meantime, I've updated the README to suggest that shoulda users use shoulda-matchers 2.8.0.

[gamov]

Is it possible, in the meantime, to use shoulda-matchers and minitest without shoulda-context (which provides the 'should' keyword?)? For example, calling them in some fashion in a regular test?

[olimart]

@gamov I've tried a bunch of things but all failed so I gave up and now waiting for the release (not sure what's holding on though).

[mcmire]

Sorry to keep you waiting. I've created https://github.com/thoughtbot/shoulda/pull/261 to address this.

Any news on this? It would be nice to use pure minitest with shoulda matchers.

@gamov @olimart @samuelpismel
I'm successfully using shoulda-matchers with standard MiniTest tests thanks to the minitest-matchers_vaccine gem:

_Gemfile_:

group :test do
  gem 'shoulda-matchers'
  gem 'minitest-matchers_vaccine'
end

_test_helper.rb_:

Shoulda::Matchers.configure do |config|
  config.integrate do |with|
    with.test_framework :minitest
    with.library :rails
  end
end

_user_test.rb_:

class UserTest <  Minitest::Test
  def test_validation
    user = User.new
    assert_must validate_presence_of(:email), user
  end
end

or using @subject and must:

class UserTest < Minitest::Test
  def setup
    @subject = User.new
  end

  def test_validation
    must validate_presence_of :email
  end
end

I have created a wiki page to help others with this problem: https://github.com/thoughtbot/shoulda-matchers/wiki/Usage-with-standard-MiniTest-tests

Thanks @zavan

[mcmire]

That is really great! I'm guessing that you can use this gem alongside shoulda-context if you like? Has anyone tried this?

[zavan]

@mcmire I haven't tried it, but I think so. The gem is super simple:
