Unit Size

The distribution of size of units (measured in lines of code).

Intro
  • Unit size measurements show the distribution of size of units of code (methods, functions...).
  • Units are classified in four categories based on their size (lines of code): 1-20 (small units), 20-50 (medium size units), 51-100 (long units), 101+ (very long units).
  • You should aim at keeping units small (< 20 lines). Long units may become "bloaters", code that have increased to such gargantuan proportions that they are hard to work with.

  • There are 1,933 units with 33,144 lines of code in units (61.9% of code).
    • 31 very long units (5,620 lines of code)
    • 105 long units (7,285 lines of code)
    • 274 medium size units (8,394 lines of code)
    • 416 small units (6,150 lines of code)
    • 1,107 very small units (5,695 lines of code)
