The distribution of complexity of units (measured with McCabe index).
Intro
- Conditional complexity (also called cyclomatic complexity) is a term used to measure the complexity of software. The term refers to the number of possible paths through a program function. A higher value ofter means higher maintenance and testing costs (infosecinstitute.com).
- Conditional complexity is calculated by counting all conditions in the program that can affect the execution path (e.g. if statement, loops, switches, and/or operators, try and catch blocks...).
- Conditional complexity is measured at the unit level (methods, functions...).
- Units are classified in four categories based on the measured McCabe index: 1-5 (simple units), 6-10 (medium complex units), 11-25 (complex units), 26+ (very complex units).
Conditional Complexity Overall
- There are 35,629 units with 1,163,723 lines of code in units (49.3% of code).
- 141 very complex units (74,703 lines of code)
- 346 complex units (60,535 lines of code)
- 4,516 medium complex units (317,898 lines of code)
- 10,498 simple units (430,030 lines of code)
- 20,128 very simple units (280,557 lines of code)
