The Way of the Web Tester

Step 1: Fix the Spacing

A quick scan of the code reveals that while the test code is spaced reasonably nicely, the class itself is in a bit of a mess. Nothing is lined up. The flow of the method is confusing. And it takes just too much mental work to figure out what is going on.

Let’s see what happens though, if we indent things properly and we inject a few well-placed lines of whitespace.

class MeterPrinter

  def print(m)

    r = StringIO.new

    case m.type
      when 'gas'
        r << "Meter Report\n"
        r << "Type: Gas\n"
        r << "Construction Co. Ltd.\n"
      when 'wind'
        r << "Meter Report\n"
        r << "Type: Wind\n"
        r << "Construction Co. Ltd.\n"
      when 'solar'
        r << "Meter Report\n"
