Do I have a healthy test suite?

Source: Owned by the author
With TDD etc we are all assuming that we have a healthy test suite. Now some researchers from the Netherlands and Belgium have published a way to actaully measure this. Their idea is to plot

  • on one axis the percentage of the total code base that is test rather than production code and
  • on the other axis the test coverage.

In a healthy project, they argue, the coverage should increase or at least not decrease while the test code percentage grows or does not decrease.
