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 ...]
