Google is extremely test-oriented, every project is covered by a test suite and there is a powerful distributed continuous integration infrastructure in place that executes tests "in the cloud" and doesn't allow to commit code that doesn't pass. Not to forget about the public Google Testing Blog[1] and the famous Testing on the Toilet[2]. People in the Ruby community also use temporary puts/logging statements for exploratory debugging, but of course nobody in right mind commits such code to the repository.
