Dark Side of Testing: The Failures We Cause Ourselves - Bart Knaack
Testing is supposed to prevent failures in production, yet sometimes the test itself is what breaks things. Bart Knaack calls this the dark side of testing, and we talk about test data leaking out of poorly protected environments, test systems that give attackers a look at your code, and why testing in production needs a risk assessment of its own. Bart would rather ask questions than hand out checklists, because a ticked box stops people thinking. He also tells the story of a team with 10,000 end-to-end test cases that ended up needing only 50.
