A sense of fun can help new practice adoptions. After reading a post by Clint Shank on coming up with a continuous integration game Erik Ramfelt went ahead and created a Hudson plugin.
Currently the points you get are:
- -10 points for breaking a build
- 0 points for breaking a build that already was broken
- +1 points for doing a build with no failures (unstable builds gives no points)
- -1 points for each new test failures
- +1 points for each new test that passes
Looks like a good starting point. I really like the idea of getting points for implementing new tests.
