I agree, and commend how well you've noted the problems when code is written without tests. Such a codebase becomes mentally exhausting and expensive to probe into; much more expensive than the original time saved by ignoring testing practices altogether. Sure, a huge amount of legacy software may not have tests, let alone comments. Then yes, it's like where do you even begin and have any confidence in what youre testing for. But ignoring proper testing practices in new, modern codebases, especially in a business where the single product or service offering is software, is extremely risky and irresponsible. This is a little ranty because why are devs justifying not writings tests in 2018!
