Shift Your Testing Mindset: From Right Answers to Fast Feedback - Jean-Francois Riverin

With Jean-Francois Riverin I get into a question that bothered him for over 20 years: why are there still bugs in production even when you tested as well as you possibly could? His answer is that software stopped being a complicated problem, like building a bridge, a long time ago. It is now complex, more like medicine or meteorology, and that means the whole idea of finding the right answer through testing is the wrong goal. We talk about what it looks like to switch that mindset, what "safe to fail" means in practice, and how to make that argument to a manager who still expects predictable budgets and zero surprises on Friday afternoons.
