Upgrade to rspec-1.2.9
What’s new
spec/spec.opts
If you have a spec/spec.opts file, the spec command will now use that automatically as long as you don’t include any options on the command line.
let()
Writing specs tends to follow a regular pattern of using local variables, discovering duplication, and then having to convert to local variables to instance variables by adding an “@” symbol. The let() method assigns the result of a lazy eval’d block as the return value of an instance method using the same name. This way you can go from this:
describe Subscription do
it "does something" do
subscription = Subscription.create :limit => 1
subscription...
end
it "does something else" do
subscription = Subscription.create :limit => 1
subscription...
end
end
to this:
describe Subscription do
let(:subscription) { Subscription.create :limit => 1 }
it "does something" do
subscription...
end
it "does something else" do
subscription...
end
end
its()
If you’re in the habit of writing one-liners using implicit subject, this new its() feature is for you. Here’s the basic idea:
describe Array do
its(:length) { should == 0 }
end
Upgrade to rspec-1.2.3-1.2.7
What’s Changed
Matcher DSL
Use Spec::Matchers.define instead of Spec::Matchers.create (which is now deprecated).
Explicit Predicate Matchers are deprecated
With the addition of the new Matcher DSL the old, confusing, and almost-nobody-uses-it explicit predicate matcher functionality’s days are now numbered.
If you’re not familiar with this feature, don’t worry about it. If you have anything that looks like this:
predicate_matchers[:swim] = :can_swim?
Or this
config.predicate_matchers[:swim] = :can_swim?
Change it to this:
Spec::Matchers.define :swim do
match do |potential_swimmer|
potential_swimmer.can_swim?
end
end
Custom Formatters
If you have an custom formatter, the add_example_group method has been changed to example_group_started, and kept as an alias so your formatters will still work. Though not yet, add_example_group will be deprecated in a future minor release, and removed in a future major release, so we recommend you make this change now.
Upgrade to rspec-1.2.2
What’s Changed
require 'rubygems' unless ENV['NO_RUBYGEMS']
After minor public outcry and confusion, we restored necessary references to rubygems in rspec. If you use a different mechanism for managing gems, just set a NO_RUBYGEMS environment variable (to any non-nil value).
Proxies and locations
This is probably only interesting to you if you use custom formatters.
Formatters now receive Spec::Example::ExampleGroupProxy and Spec::Example::ExampleGroup objects with cohesive APIs for reporting. See the RDoc for those classes and Spec::Runner::Formatter::BaseFormatter for more information.
What’s new
The new matcher DSL works with test/unit (without the rest of rspec)
We’ll be separating this out to its own gem for rspec 2.0, but for now, just install rspec >= 1.2.1 and add the following to your test_helper file:
require 'spec/expectations' class Test::Unit::TestCase include Spec::Matchers end
This will add should() and should_not() to your objects, make all of rspec’s built-in matchers available to your tests, INCLUDING rspec’s DSL for creating matchers (see below, under Upgrade to rspec-1.2.0)
debugger
If you have ruby-debug installed, you can set a breakpoint by adding debugger() in your code:
# some code ..... debugger # some more code ....
… and using the --debugger or -u command line option.
spec path/to/file.rb --debugger
Upgrade to rspec-1.2.0
What’s Changed
WARNINGS
- If you use the ruby command to run specs instead of the spec command, you’ll need to require ‘spec/autorun’ or they won’t run. This won’t affect you if you use the spec command or the Spec::Rake::SpecTask that ships with RSpec.
- require ‘spec/test/unit’ to invoke test/unit interop if you’re using RSpec’s core (this is handled implicitly with spec-rails)
- setup and teardown are gone - use before and after instead
- you can still use setup and teardown if you’re using Test::Unit::TestCase as the base ExampleGroup class (which is implicit in rspec-rails)
- The matcher protocol has been improved. The old protocol is still
supported, but we added support for two new methods that speak a bit more
clearly:
failure_message => failure_message_for_should negative_failure_message => failure_message_for_should_not
- All references to rubygems have been removed from within rspec’s
code.
- See gist.github.com/54177 for rationale and suggestions on alternative approaches to loading rubygems
What’s New
Ruby 1.9
RSpec now works with Ruby 1.9.1. See wiki.github.com/dchelimsky/rspec/ruby-191 for useful information.
Improved heckle integration
RSpec works with heckle again! Gotta use heckle >= 1.4.2 for this to work though, and it only works with ruby-1.8.6 and 1.8.7 (heckle doesn’t support 1.9.1 yet).
[sudo] gem install heckle --version ">=1.4.2" spec spec/game/mastermind.rb --heckle Game::Mastermind
New Matcher DSL
We’ve added a new DSL for generating custom matchers very simply and cleanly. We’ll still support the simple_matcher method, so never fear if you’re using that, but we recommend that you start developing your new matchers with this new syntax.
Spec::Matchers.create :be_a_multiple_of do |smaller|
match do |bigger|
bigger % smaller == 0
end
end
9.should be_a_multiple_of(3)
