I think a goal of 100% coverage is ridiculous if taken too seriously, but I do think that

    Untestable code is low-quality code.

Note that I don't say "untested", I say code that cannot be tested. As projects grow it becomes harder to introduce tests if you didn't think about testability as you went along. And there goes your quality.

But for me, the strongest takeaway from the bits I've read about XP, TDD, and so on is the principle that you should always be free to rework what you have. I think you can get it right the first time, but then time passes and it is no longer very right. If you have tests and enough support from your development culture, you are not afraid to refactor, redesign, rewrite. All in the appropriate degree, of course. Don't throw everything away as change comes. Only what you need to.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
