The whole point of coding it beforehand is that later you won't have time to fiddle with coding and testing; whereas right now, you do.

The idea is that if you can build something smaller and faster while keeping the code clean enough to add to later, you can deliver it months earlier. I think we've all seen programmers waste time on pet abstractions in pursuit of a cool architectural idea.

This is one of those comfortable academic ideas that doesn't make much business sense: doing a lot of work on a program, that if done correctly, will result in a product that does the same exactly same thing as it did before, and if done wrong might ruin the product.

If you let things get to the point where refactoring is "a lot of work", you've already screwed up. You're supposed to do it as you build the program, so that you get the benefits of cleaner code while you are building it.

In order to test, you need to know exactly what you're testing, and how. To properly test a section of the program, you need to define what that section does, and how it does it (all preconditions, post conditions, and side effects, etc.) You can't do that until you write the code

At some point, you define the interface. It could be while coding, or it could be while writing tests. You will probably make some changes over time, but the work of defining the interface has to happen anyway, so it's not wasted time.

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.
