No. That's the job of unit tests, integration tests and your CI/CD pipeline or alternatively the test environment (dev, staging, quality control, you name it...). Moreover, the person having written the code is supposed to have checked that it runs and meets business requirements - although the latter should be ultimately checked by your Product Owner or client.

I do test manually when the author does not practice TDD. (Or if there aren't tests.)

Additional benefit is that this shows to devs and management what a time saver TDD and testing in general is. It shows immediately that lacking tests cost valuable, senior, time, rather than save time by not writing tests.

It also is simply needed: when there are no tests, we'll need to manually verify and check for regressions.

makes me sad to see this so far down.
