Grown-up software developers know perfectly well that testing is important. But — speaking here from experience — many aren’t doing enough. So I’m here to bang the testing drum, which our profession shouldn’t need to hear but apparently does.
My general thought was, that we maintain the quality of the code to be quite high, and we have a reasonably good work methodology.
