I like TDD in theory and I spent so many years trying to get it perfect. I remember going to a conference where someone was teaching TDD while writing tic tac toe. Unsurprisingly, he didn't finish in time.

The thing that I hate is people conflating TDD with testing or unit testing. They're vastly different things. Also, I hate mocks. I spent so long learning all the test doubles to pass interviews: what's the difference between a spy, fake, stub, mock, etc. Also doing it with dependency injection and all that. I much prefer having an in-memory database than mock what a database does. Last company I worked at, I saw people write tests for what would happen if the API returned a 404 and they wrote code that would handle it and all that. In practice, our HTTP library would throw an exception not return with a statusCode of 404. Kinda funny.

You obviously can't always get replacements for things and you'll need to mock and I get that. I just prefer to not use them if I can.

Also, TDD advocates love saying, you're just not doing it well or you just don't know enough.

I get it, you love TDD and it works for you and more power to you.

I definitely believe in testing and having resilient tests that will minimize changes upon refactoring, but TDD doesn't work for me for most of the work I do. It works for some and I love it when it does, but yeah .... sorry random long ramble.

This reminds me when a senior engineer asked me to write exception handling on a one-off python script, not a production code - just a script devs can use internally. The "handling" was that the program should exit when a file is not found. He wanted me to try the file open, except the file error, print "file not found" message and exit(1).

Guess what, genius. Python already does that for you. No need to write an extra wrapper needlessly.
