See the test suite.
N.B.: Overwriting files or functions a.k.a. cheating is not necessary.
I don't think the test suite works. It errors out with 'Undefined function or variable your_code'. Can't figure out why.
It works for me. It may be a little tricky.
I agree with Guillaume, the test suite can't work.
Someone already solved it yesterday. If I tell you how to solve that obstacle, I would make it a lot easier.
Just a little hint: I bet you can solve it in your own computer without changing the test suite.
The problem I believe is that your test suite is linux specific, so it's impossible to find why it doesn't work on a Windows computer. On Windows, your echo command creates invalid files as it writes the quotes to the files. If I remove the quote from your echos, my solution works fine on Windows.
That is true. But Cody is running on Unix. Anyhow, I have modified the test suite to be platform independent.
