I'm currently at a phase where I'm just not as worried about TDD or Unit testing. I've realized that most of my buggy code is in integration points. For example, I'm working on an internal project that creates VMs with some provider (be it Virtual Box, AWS, etc) and then deploys a user defined set of docker container to it. I've found that I don't have bugs in situations I would typically test using mocking/stubbing/etc in traditional unit tests. I usually need to have the real AWS service with the docker service running to get any value out of the test. And at that point it's more work to mock anything else than it is to just start up the app embedded and do functional testing that way. I'm becoming more of a fan of verifying my code with some good functional tests in areas that feel like high risk and then some contract testing for APIs other apps consume. Then if I find myself breaking areas or manually testing areas often I fill those in with automated tests.
