Metamorphic testing: how to check code when you can't predict the output
Most testing advice assumes you already know the right answer. You call the function, you assert it equals the value you wrote down, green. That assumption breaks the moment the output is hard to predict: a ranking function, a route planner, a physics simulation, a machine-learning classifier, an L…
