I heard this a few times in the ruby community by some well known figures like Sandy Metz. Simple example : time related tests can be cumbersome to setup, but if you inject time in the method, test becomes easy, incidentally improving your design by not relying on globale objects... But I am sceptical this can work without knowing and practicing good design principles (SOLID) independently from tests ! However I believe tests are super important for refactoring, wether the design is good or not. My 2 cents : if the design is bad, (spaghetti and all) tests should be done more at the functional level, when your confident design is getting good then rely more on unit test |
