Asp Forum - [ANN] Bacon 0.9, a small RSpec clone

Hello,

Today I'm proud to release Bacon 0.9.

= Bacon -- a small RSpec clone.

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

Bacon is a small RSpec clone weighing less than 300 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/rep...)

== 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 ...]

== Object#should

You can use Object#should outside of contexts, where the result of
assertion will be returned as a boolean. This is nice for
demonstrations, quick checks and doctest tests.

>> require 'bacon'
>> (1 + 1).should.equal 2
=> true
>> (6*9).should.equal 42
=> false

== Where can I get it?

You can download Bacon 0.2 at

http://chneukirchen.org/releases/bacon-0....
http://rubyforge.org/project...

Alternatively, you can checkout from the development repository with:

darcs get http://chneukirchen.org/r...

(Patches using "darcs send" are most welcome.)

== Installing with RubyGems

A Gem of Bacon is available. You can install it with:

gem install bacon

I also provide a local mirror of the gems (and development snapshots)
at my site:

gem install bacon --source http://chneukirchen.org/rel...

Is it compatible with Test::Unit like Test/Spec ?

Is this a replacement for test/spec, or is test/spec bacon's big brother?

It is not a replacement for test/spec, but a reimplementation of the
ideas behind it in a compact way.

It does not use Test::Unit.

It is not completely compatible to test/spec or RSpec, but suites are
reasonably easy to port.

It's unfortunate you didn't name contexts strips and examples bits.
You really could've played up this bacon thing. :)

I like the way this looks. It plays nice with some specs I was working on.

Thanks for finally gemming it up! I just started writing the specs for
Halcyon and was really distraught over using RSpec or Bacon. Very cool
and very good timing.

Also, again, I think this is a very cool name considering its inspiration.

Cheers,
Matt

Okay, time to admit that quote was not *really* the inspiration... :-)

Bacon in German is Speck, which is written and sounds like spec.

Neat...I checked out the code and it looks very nice and slim.

My only concern is converting our many thousands of lines of specs
written in test/spec if bacon is where all the goodness is going to be
happening =).
