SHOULDA BEEN GONE

We haven’t been taking pull requests on shoulda-matchers as much as we shoulda, but it’s back in the spotlight now. Shoulda’s been gone … but it’s back.

Here are the new features in shoulda-matchers 1.1.0:

• A NEWS file so you can track new hottness in REAL TIME
• shoulda-matchers’ very first dependency: ActiveSupport >= 3.0.0. This was an implicit dependency for a while, but now it’s official.
• An only_integer option for validates_numericality_of
• A query_the_database matcher, so that you can do it { should query_the_database(4.times).or_less }
• Database column primality is correctly checked
• The flash matcher can check specific keys using [], like so: it { should set_the_flash[:alert].to("Bad username") }
• A validates_confirmation_of matcher: it { should validate_confirmation_of(:password) }
• A serialize matcher: it { should serialize(:details).as(Hash).as_instance_of(Hash) }
• A have_sent_email matcher can now check reply_to: it { should have_sent_email.reply_to([user, other]) }
• An accept_nested_attributes matcher

If you filed a pull request and we didn’t take a look, please re-submit or ping me on Github. We’d love to hear from you.

This Week in Open Source

clearance

Gabe Berke-Williams (gabebw - that’s me!) cleaned up the clearance Rakefile a bit (4f016db).

factory_girl

Joshua Clayton (joshuaclayton) released version 3.1.0 of factory_girl (f1d3018). For the full list of changes, see the NEWS file. Josh updated a few dependencies too (20becc9, 29157d6). Kristian Mandrup (kristianmandrup) added the ability to alias sequences, just like you can alias factories (f387e38, 178a7ab). To see how to use it, see the documentation (f013335) he added for it. I love documentation pull requests.

factory_girl_rails

Joshua Clayton (joshuaclayton) bumped factory_girl_rails to version 3.1.0 (4259e4c) to match factory_girl’s new version.

paperclip

Prem Sichanugrist (sikachu) released version 3.0.2 (240147e) of paperclip. Unfortunately, the NEWS file hasn’t been updated for 3.0.2 yet. Prem removed an obsolete generator, then added a test for it (a2a4c7a, 03700c8). Preston Guillory (pguillory) fixed a typo (853595a). Typo fixes are always welcome! Michael Galero (mikong) pluralized the table name in the migration generator to follow Rails convention (28e2d1b). And Rafael Mendonça França (rafaelfranca) removed init.rb, since plugins will be deprecated in Rails 4.0 (ae7b7c5).

shoulda-matchers

Gabe Berke-Williams (gabebw - me again!) finally released a new version of shoulda-matchers! Version 1.1.0 has a bunch of changes that you can see in the NEWS file. One of the noteworthy changes is that shoulda-matchers now depends on ActiveSupport >= 3.0.0 (c65e43a), meaning it’s Rails 3-only. We’ve been only testing against Rails 3 for a while, so this just makes it official. Gabe made a couple of documentation fixes (9203275, 8fcc3d2, a4edff0) and also cleaned up the code (5873502, 41088bc, 3039cc6, 820f216, 2e73b35, 457be62). Brendan Loudermilk (bloudermilk) added an accept_nested_attributes_for matcher (ee74222).

this-week-in-open-source

Finally, Gabe Berke-Williams (gabebw) fixed a little bug in this-week-in-open-source (which I used to generate this post!) to print missing directories before doing anything else (564c7c9).

This week in open source

laptop

I was reminded that I’ve been missing out on our sweet laptop script, which is a program we maintain to get a Rails environment set up on OS X as quickly as possible. So over the past week, Antonio Salazar Cardozo (Shadowfiend) fixed our capitalization of Qt (b667280), Prem Sichanugrist (sikachu) fixed our capitalization of JavaScript (87fe88f), and Dan Croak (croaky) removed the deprecated Heroku Labs plugin (842cd0d) and gave instructions on installing the command-line XCode tools (a177cca).

suspenders

The suspenders gem, which has helped many people start a Rails app, now shows that the build is broken. Gabe Berke-Williams (gabebw) added that (76e42eb).

shoulda-matchers

The shoulda-matchers gem is a collection of RSpec matchers for various Rails things. Gabe Berke-Williams (gabebw) went to town on it this week, cleaning everything up in an effort to make it more pleasant to hack on (2b98e49, 09544fa, 7b3d6d0, 96df0b1, 36006d8, 4ff1344, 3b3181b, 4574f51, 1c517d2, bd52483, e70e1bf, 41bccc8). Having done that, he added a :primary option to the have_db_column matcher (68e65b2). Matthew Daubert (MDaubs) fixed a JRuby failure and also added support for Rails 3.0 (d85503f).

bourne

Due to my complaining last week, the bourne gem now has a NEWS file (8dfb077), thanks to Gabe Berke-Williams (gabebw).

paperclip

So we have this gem named paperclip. You might have heard of it. This week, Tony Brewerio (tony-brewerio) fixed the :content_type validator (c4c22f8).

Prem Sichanugrist (sikachu) released version 3.0.1, which breaks backward compatibility (d61ddd5, 51bb0f9, 7088f5b, e1951ed, 9ea4a9b, 36d1289, 8390516, b3f9690, 8e80310, ee4107a, b3a63ed, 8a758c2, 84d2d08, fe706c6, b54904e, d3a7427, da5d716, ee42b19, e83f88f, 03f777f, 5232b19, 19aedbc).

Jon Yurek (jyurek) merged in something he has been working on: adapters for different types of I/O (6c5fe19, e10edcd, f4b6d48, 78cfebd, 89c8d11). Adding new file-like things is now easier, including URLs that act like files. Yeah, that’s right.

Jon is so going to write a blog post about this with more explanations, after he updates the README.

factory_girl

A bunch of fun commits to factory_girl this week. Chris Griego (cgriego) used pull requests as a forum to promote his ActiveAttr gem (81c9f2c and 4e2a672). Joshua Clayton (joshuaclayton) added a before_create callback (24d417d).

Vasiliy Ermolovich (nashby) used ActiveSupport for deprecation warnings (bca13f1 and 28e3c25) and also made use of the singleton_class method in Ruby 1.9 (08d01c1).

Mike Subelsky (subelsky) fixed a typo in the docs around the name FactoryGirl::Syntax::Methods (266b1d6), Dan Croak (croaky) mentioned the supported Ruby versions in the README (bed50ec), Josh renamed Changelog to NEWS because that’s exactly what it is (4f5b775) and also renamed *rb files to *erb to handle yardoc better (a6ccbcb).

capybara-webkit

I totally dropped the ball on releasing a new version of capybara-webkit this week. Sorry about that! Joe Ferris (jferris), however, refactored some of the C++, which is very welcome (c2a2bd0 and 4531f65).

appraisal

Some news in our appraisal gem this week: Gabe Berke-Williams (gabebw) added a contribution guideline (fd05fdf), then osheroff fixed appraisal to handle weird filenames (1d4fa93, b21220a, and 75a4970).

Do End Your Braces

Braces and do/end are completely swappable—almost all the time. They have different precedence. It’s not often that anyone comes across what this means in practice.

In shoulda, these do different things:

should redirect_to('#edit') { article_edit_path(@article) }
should redirect_to('#edit') do
  article_edit_path(@article)
end

To get a better grasp on the differences, consider these two simple methods:

def outer(inner, &block)
  inner
  block.call('outer') if block_given?
end

def inner(&block)
  block.call('inner') if block_given?
  1
end

Here outer is analogous to should and inner to redirect_to. Instead of having any real logic, though, they call a block with what they are. In practice:

outer inner {|where| puts "#{where} called me"}

# "inner called me"

outer inner do |where|
  puts "#{where} called me"
end

# "outer called me"

Short, explicit test setups

You probably know about this Factory Girl definition syntax:

FactoryGirl.define do
  factory :user do
    name 'Connie Customer'
  end
end

But did you know about this Factory Girl invocation syntax?

setup do
  @user = create(:user)
end

Or:

setup do
  @user = build(:user)
end

Or:

setup do
  post :create, user: attributes_for(:user)
end

It’s in there.

Configuration for Test::Unit / Shoulda:

class ActiveSupport::TestCase
  include FactoryGirl::Syntax::Methods
end

Configuration for RSpec:

RSpec.configure do |config|
  config.include FactoryGirl::Syntax::Methods
end

Configuration for Cucumber:

World FactoryGirl::Syntax::Methods
