"I now spend less time testing...rely more on logging" /via Karl Seguin  #readingToday 

To conclude, it's safe to say I still believe in unit testing and I feel that integration tests are becoming more and more critical. I now spend less time testing: unit tests are focused on testing code, not interactions, and integration tests are the common paths. I rely more on logging which is easier to implement and other benefits, to ensure that the system behaves as it should.
