MiniTest: A curious case of include (1.8 vs 1.9)
require 'rubygems'
require 'minitest/spec'
module A
module B
end
end
class DirectInclude
include A
end
class EvalInclude
end
EvalInclude.class_eval "include A"
class BlockInclude
end
block = lambda { include A }
BlockInclude.class_eval(&block)
class MethodEvalInclude
class << self
def class_include(&block)
class_eval(&block)
end
end
end
MethodEvalInclude.class_include { include A }
describe "Manual Includes" do
it "should show direct inclusion works" do
DirectInclude::B.must_equal A::B
end
it "should show eval inclusion works" do
EvalInclude::B.must_equal A::B
end
it "should show block inclusion works" do

#
# Including a module in a spec does not make constants
# available under ruby 1.8 but it does under ruby 1.9.
#
# This script requires the minitest gem to be installed:
#
# % gem install minitest
#
# See: http://groups.google.com/group/ruby-talk-google/browse_thread/thread/a8a516f8732150db
module A
module B
end
end
# This passes on ruby 1.9, but not on 1.8.
describe "MiniTest Includes" do
include A
it "should show inclusion works" do
B.must_equal A::B
end
end
# This passes on both. What's more, if you uncomment this
# spec, the assignment TRANSLATES to the "MiniTest Includes"
# spec and that spec will pass! It indicates some pollution
# of one spec with another.
#
# describe "MiniTest Assigns" do
# B = A::B
#
# it "should show assignment works" do
# B.must_equal A::B
# end
# end
#
# NOTE: it's actually pollution of the enclosing namespace!
# You can show this:
#
# puts B # => 'A::B' on 1.8, error on 1.9
#
# Here is an example showing the assignment case works.
module X
module Y
end
end
describe "MiniTest Assigns X::Y" do
Y = X::Y
it "should show constant assignment works" do
Y.must_equal X::Y
end
end
# Here are some workarounds...
module M
module N
end
describe "Nested" do
it "should show nesting works" do
N.must_equal M::N
end
end
end
describe "Full Constant Name" do
it "should show full names works" do
M::N.must_equal M::N
end
