[ANN] Bacon 1.0, a small RSpec clone

Hello,

Today I'm proud to release Bacon 1.0.

= Bacon -- small RSpec clone.

   "Truth will sooner come out from error than from confusion."
                                               ---Francis Bacon

Bacon is a small RSpec clone weighing less than 350 LoC but
nevertheless providing all essential features.

== Whirl-wind tour

    require 'bacon'
    
    describe 'A new array' do
      before do
        @ary = Array.new
      end
      
      it 'should be empty' do
        @ary.should.be.empty
        @ary.should.not.include 1
      end
    
      it 'should have zero size' do
        @ary.size.should.equal 0
        @ary.size.should.be.close 0.1, 0.5
      end
    
      it 'should raise on trying fetch any index' do
        lambda { @ary.fetch 0 }.
          should.raise(IndexError).
          message.should.match(/out of array/)
    
        # Alternatively:
        should.raise(IndexError) { @ary.fetch 0 }
      end
    
      it 'should have an object identity' do
        @ary.should.not.be.same_as Array.new
      end
    
      # Custom assertions are trivial to do, they are lambdas returning a
      # boolean vale:
      palindrome = lambda { |obj| obj == obj.reverse }
      it 'should be a palindrome' do
        @ary.should.be.a palindrome
      end
    
      it 'should have super powers' do
        should.flunk "no super powers found"
      end
    end

Now run it:

    $ bacon whirlwind.rb
    A new array
    - should be empty
    - should have zero size
    - should raise on trying fetch any index
    - should have an object identity
    - should be a palindrome
    - should have super powers [FAILED]
    
    Bacon::Error: no super powers found
    	./whirlwind.rb:39: A new array - should have super powers
    	./whirlwind.rb:38
    	./whirlwind.rb:3
    
    6 specifications (9 requirements), 1 failures, 0 errors

If you want shorter output, use the Test::Unit format:

    $ bacon -q whirlwind.rb
    .....F
    Bacon::Error: no super powers found
    	./whirlwind.rb:39: A new array - should have super powers
    	./whirlwind.rb:38
    	./whirlwind.rb:3
    
    6 tests, 9 assertions, 1 failures, 0 errors

It also supports TAP:

    $ bacon -p whirlwind.rb
    ok 1        - should be empty
    ok 2        - should have zero size
    ok 3        - should raise on trying fetch any index
    ok 4        - should have an object identity
    ok 5        - should be a palindrome
    not ok 6    - should have super powers: FAILED
    # Bacon::Error: no super powers found
    # 	./whirlwind.rb:39: A new array - should have super powers
    # 	./whirlwind.rb:38
    # 	./whirlwind.rb:3
    1..6
    # 6 tests, 9 assertions, 1 failures, 0 errors

    $ bacon -p whirlwind.rb | taptap -q
    Tests took 0.00 seconds.
    FAILED tests 6
       6) should have super powers: FAILED

    Failed 1/6 tests, 83.33% okay.

(taptap is available from http://chneukirchen.org/repos/taptap/)

== Implemented assertions

* should.<predicate> and should.be.<predicate>
* should.equal
* should.match
* should.be.identical_to / should.be.same_as
* should.raise(*exceptions) { }
* should.change { }
* should.throw(symbol) { }
* should.satisfy { |object| }

== Added core predicates

* Object#true?
* Object#false?
* Proc#change?
* Proc#raise?
* Proc#throw?
* Numeric#close?

[... for more documentation see README ...]

== Where can I get it?

== Thanks to

* Michael Fellinger, for fixing Bacon for 1.9 and various improvements.

* James Tucker, for the autotest support
* everyone contributing bug fixes.

== History

* January 7, 2008: First public release 0.9.

* July 6th, 2008: Second public release 1.0.
  * Add Context#should as a shortcut for Context#it('should ' + _).
  * describe now supports multiple arguments for better organization.
  * Empty specifications are now erroneous.
  * after-blocks run in the case of exceptions too.
  * Autotest support.
  * Bug fixes.
