If you test at a high enough level you shouldn't have to throw the tests away while refactoring.

  You need throwable characterization tests when you don't know what the legacy code is supposed to do, but don't want to change its behaviour.

    Why should those characterizing tests be throwable if you don't want to change its behavior?
    • grayclhn 11y ago
      Because you may want or need to change aspects of the behavior, but not while refactoring.
