“Tests are useless if they don’t fail.”

Some time ago, I saw this statement passing by on Twitter. My first thought was, why? Why are tests useless when they don’t fail. I disagree with that. Test is about gathering qualitative information. Test is about questioning the product to observe it, to learn from it. Test is about making informed decisions. If a…

First Impression Test
