Thanks for the explanations, Costi G. I didn't thought that the `DATA`
constant isn't seen by the interpreter if it is in the required file.
The only solution that I can think of right now is the following:
~~~
# data_spec.rb
describe 'DATA' do
it 'contains lines following the __END__ keyword' do
data = File.read(__FILE__).split("__END__\n")[-1]
data.should == "Hello from the underground!\n"
end
end
__END__
Hello from the underground!
