one-time data conversion script.
I would not write tests for a one-time data conversion script. There's only one test for a one-time script: its run.

    Arguably, feeding the head of the 25GB input file to your one-liner and checking the output displayed looks right, is a different one-time script to the feeding it the whole thing and redirecting the output to the results file.

    But it's definitely a test worth doing :)

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.

    The start of some sanity?

      Of course, no disagreement there. I certainly would not write a test suite using Test::* for that.

        As may be obvious by now, neither would I :)

    I don't think anyone is advocating writing tests for one-time data conversion scripts. Certainly I am not.

    I think you've confused all the things that you think I said into newer meta-things that I haven't said.

    Rule 6, "Testing will go on as long as it has to." only matters if you're optimizing. If you're not optimizing (or any sort of refactoring) that data conversion script, then no testing need take place.
