RSpec and Ruby 1.9
Currently, RSpec (core) is mostly compatible with Ruby 1.9.1. There are still outstanding issues, some of which we plan to address and some we don't.
RSpec/Test::Unit interop will run with the test-unit-1.2.3 gem, but you must install it.
Due to changes in scoping rules, class variables within example groups are not supported in Ruby 1.9.
describe "a class variable" do @@class_variable = "a class variable" it "can access class variables in examples in Ruby 1.8" do with_ruby 1.8 do @@class_variable.should == "a class variable" end end it "can NOT access class variables in examples in Ruby 1.9" do with_ruby 1.9 do lambda do @@class_variable.should == "a class variable" end.should raise_error(NameError) end end end
