Subject: Re: Questions about test-driven development and optparse

If I were you, I wouldn't use regexps for testing the output here.
That would imply that you're basically only checking that the output
format is right.

You should probably take a simple, short log file, and package it with
the tests. Then run it once for each options combination you want to
test, save the output (which you have manually verified is correct),
and write a test that checks the the output still looks exactly the
same.


You could also just forget about tests here entirely. What you have
here is (when you don't count country code list and documentation) a
100-line script that does just one thing, and you've already verified
it works. Tests are only useful in one case – when you are making
changes to your software and want to make sure they don't introduce
bugs in old code.

Still, it might turn out later that you actually need to change stuff,
and then you'll be wishing you wrote the tests earlier :(
