Write spec for class var behavior
Reported by Evan Phoenix | May 18th, 2008 @ 07:22 PM | in 1.0 preview
module B
def blah
@@blah ||= []
p @@blah.include?(1)
end
end
class A
extend B
end
A.blah
This code creates class variable @@blah on B, not A. Rubinius recently fixed it's handling of this, but a spec needs to be written to document the behavior.

Rubinius behavior still seems to be different.
describe "Module" do
it "should assign ownership of class variables to the Modules metaclass when class variables are defined as part of method evaluation" do
declare_class_variable = Module.new do
def define_class_var
@@class_var = :value
end
end
access_class_variable = Module.new do
extend declare_class_variable
end
access_class_variable.define_class_var
declare_class_variable.class_variable_defined?("@@class_var").should == false
access_class_variable.class_variable_defined?("@@class_var").should == false
declare_class_variable.instance_eval("class << self; self; end").class_variable_defined?("@@class_var").should == true
end
end
