what is testing nirvana?
you want to write tests
know what to test, what not to test
confidence in your code
more productive writing tests before code,
then just code alone

Testing
‣ *Unit test runner (JUnit, NUnit)
‣ code coverage (rcov, NCov)
‣ test augmenter (jester, pester, heckle)
‣ high level testing (fit, story)
Refactoring
‣ IDE plugin (anything by JetBrians)
‣ code analyzer (fxCop, flog, saikuro)
‣ Smalltalk Refactoring Browser
Automation
‣ CI tools (cruisecontrol*)
‣ continuous test runner (autotest)
‣ continuous code metric (autometric)
