Tracking Code Quality

  • Presentation by Marty Andrews
  • The Cyclomatic Complexity of a method is really the minimum number of unit tests needed to test very path in a method.
  • By reducing CC, usually by breaking large methods down, you reduce the number of tests you need to write !
  • Complexian - www.cogentconsulting.com.au/resources/complexian/index.html
  • FindBugs - usually needs human to interpret. Good to hook in but not run in CI. Human can run so often
  • SourceMonitor
  • JOODI - Package level checking. Good to enforce certain layers only access other layers e.g.
  • Spec#
  • Clover2
    • Project Risk Coverage Cloud - A tag cloud containing every class that exposes those which have low test coverage but high cyclomatic complexity
    • Custom Columns - Define your own quality metric by combining any of Clover's built in ones
    • Track code quality over time using historical charts and reports
